Dining Out: A Major Contributor in COVID-19 Transmission

Man with mask eatingOh how we all love to eat! And going out to our favorite restaurants makes it all the more fun, but now we have COVID and this is one situation that we cannot turn our heads and pretend that it is not there.

This omnipresent virus has turned the world upside down and by the looks of it, things are not going to change anytime soon. The rapid spread of the coronavirus continues to steadily infect people in nations worldwide. But between the intractable virus and healthcare professionals struggling to concoct an antidote, the public is desperately looking for some solace.

And what better way to gain some well-deserved comfort than gorging on delicious food? Owing to the widespread uncertainty and suffocating restrictions due to the pandemic, people are running out of patience and doing things they shouldn’t be, such as dining out any chance they get.

Eating at Bars and Restaurants: A Big No-No

Who knew that the seemingly unimportant saliva would become such a threat to the simple pleasure of eating out? But sadly, that’s what the world has come to because now the dribble that is ever ready to drizzle down at first sight of appetizing food can take lives.

And whether you like it or not, restaurants and bars are its main attacking arenas, which is why dining out is extremely dangerous these days.

A study conducted in September revealed that people who tested positive for the coronavirus are twice more likely to have eaten at a restaurant than those who tested negative. This means that no matter how quickly you devour a chocolate pie at a swanky café or gobble down the ever-popular succulent hamburger at your favorite fast food joint, you are equally at risk of contracting the novel coronavirus.

Mask or No Mask: The Threat Remains

Illustration of people wearing masks for the United NationsThe unfortunate circumstance about eating is that it requires you to open your mouth, which means you will be exposed to respiratory drops one way or another.

So even if you are one of those honorable people who always abide by COVID policy, you will have to compromise on your principles and go against the mandated restrictions when having a meal. Unless you find a way to consume food without removing your facemask, you will increase the odds of acquiring the virus, as well as endangering others by eating outside of your home.

According to the Center for Disease Control, eating at restaurants is a chief risk factor in spreading the SARS-Cov-2. Just thirty minutes of exposure to someone carrying the virus can leave you infected. Moreover, sharing dips and dishes is also a veritable source of COVID-19 transmission. You never know if a sauce you are sharing with someone carries droplets from an infected person’s mouth, which can, in turn, give you the infection.

And since not all COVID patients exhibit symptoms, someone can transmit the virus without ever knowing that they had the disease in the first place (asymptomatic). Simply put, there is no way you can dodge the coronavirus bullet at an indoor eating place.

Can You Wheedle Your Way Into the Dining Out Fun?

The coronavirus pandemic has been going on for quite a while now, prompting restaurant and bar owners to shut down business every few weeks during the past year to control the disease’s transmission. But without an end in sight, bistro owners are forced to look into ways to keep the business up and running despite the health threat. And that is why many restaurateurs are employing creative techniques to stay afloat.

Long story short, you might be able to enjoy dining out after all, but not without a slew of restrictions.

Taking Inspiration from the Italians

Just as Italy was beginning to recover from the coronavirus’s first wave, a second tide washed over the country. Businesses were only starting to open up again, but as the biting winter winds rolled around, people began falling sick again.

A second wave of the pandemic meant lockdowns in cities and restrictions on social gatherings. In the wake of which, restaurant owners had to find a way to keep their diners in business without taking any drastic measures such as doubling their prices. And that is what the owners of VagInUfezzi Bologna did.

To survive the resurgence of the coronavirus, Antonella De Sanctis and her husband, MircoCarati decided to follow the post-war Bolognese osterie, a tempo’s lead to save VagInUfezzi Bologna from a loss. Now, the diners are coming to satiate their hunger by paying by the hour instead of the dishes being served. So the less time someone spends inside the restaurant, the less they pay.

A table at VagInUfezzi Bologna costs $21.00 per person for one hour and $31.44 for two hours, excluding wine, liqueurs and coffee. And adhering to the social distancing rules, the restaurant has gone from catering to 25-30 people at a time to just 10-15.

Antonella and Micro didn’t want to suddenly shoot up the prices of their dishes because they thought that would be unfair on the eaters. Hence, they chose to charge people by the hour; this way, visitors get to enjoy the experience of dining out while minimizing the risk of COVID transmission.

In order to pay as little as possible, diners eat quickly and vacate the tables, which in turn reduces the duration of exposure. In short, the less time spent at the bistro equals less cost and minimal chances of contracting the coronavirus.

However, putting a time constraint on diners eating out doesn’t completely eliminate the possibility of catching the virus, but that seems to be the only viable option to save eatery businesses. 

Is There Light at the End of the Tunnel?

According to the guidelines published by the CDC, it’s safer to stick to pick-ups, drive-throughs and delivery services to satisfy your taste buds during the pandemic. And if you still choose to go to a restaurant to eat, be sure you wear a mask at all times, maintain a six-foot distance from fellow diners and not touch anything unnecessarily. You should also keep a bottle of hand sanitizer on you and avoid sharing dips, sauces, or any food.

Additionally, the vaccine is coming and will be here hopefully by the end of the year, but until then, follow all COVID policies and work out a plan for eating out so you can minimize getting infected while also helping to keep restaurants financially alive.  

 

Role of Nurses in the Healthcare Environment

The profession of nursing is often looked down upon on the pretext that it has no major role to play in medical healthcare other than checking blood pressure and pulse, administering the medicine prescribed by the doctors and other tasks of the sort.  Looking at the hefty degrees and expansive experiences of the doctors, quite a few people assume that doctors are all that the medical arena comprises of. This notion cannot be further from the truth and during this time of the COVID epidemic, it is indeed unfortunate for people to have this false notion. It plays right into the idea that in order to be important, you have to be ‘out there’ and ‘in-your-face’.

The sight of a doctor clad in his or her radiant white coat or surgery scrub might be impressively daunting to see, but what most ignore are the nurses not only following the doctors but their swift train of commands as well. And it’s anything but easy to do. The medical science and healthcare advancements as we see them today, owe a lot to the role that nurses have been playing all along.

Let’s look at the training a person has to go through before becoming a nurse.

Nurse Training

Generally, to become a nurse, you must have at the very least achieved a two-year degree in nursing, which includes medical classes same as a freshman and sophomore doctor would take, but a four-year college degree would be preferred due to the competition a person might be subjected to when applying for the position.

A two-year degree would give you the title of an LPN – Licensed Practical Nurse. A four-year graduate would make you an NPN – Licensed Registered Nurse.

If you want to pursue a higher level of nursing, you can become nurse practitioners, nurse anesthetists or nurse midwives, which requires a master’s degree. Additionally, nurse anesthetists are also required to complete 800 hours of clinical work after they have graduated with their MS.

After all that, you need to take the NCLEX exam, AKA National Council Licensure Examination, which is a required test that every prospective nurse needs to take which will determine if you are ready to become licensed as a nurse.

Now, let’s look into a few of the important roles that nurses play in facilitating effective health care:

Handling Crucial First Aid

Admit it or not, first aid is the most crucial part of the treatment, more so in emergency cases. Nurses are almost always responsible for looking into cases requiring immediate help. Whether or not a patient is able to survive until the doctor takes over the case is entirely dependent on the efficacy of the first aid and the usage of just the right life-saving techniques. Having been trained in such preliminary crucial procedures, nurses are at the heart of first aid administering and keeping the patient stable for further treatment.

Being the Source of Information to Patients

Doctors don’t always have the time to address each and every concern of the patients in detail by explaining to them about their disease/illness; which is quite understandable considering how such a large number of cases they have to tend to. As such, it is the nurses whose patients turn to when they have important questions to ask. Especially the patients who are admitted in the hospitals for days on end, this role of nurses becomes all the more important. From medicines to all sorts of strange discomforts or pains a patient might feel, it is the nurse who is a single bell away and who looks into what’s bothering the patient.

The Bridge Between Patient and Doctor

This is the most important role that a nurse plays. Doctors are mostly dependent on the report of the preliminary assessment done by the nurses for further treatment. The most trivial of things also matter when it comes to healthcare. As such, it is the nurses who facilitate this by collecting all that information and effectively passing it on to the doctor.

Also, any complaints that a patient might have are directly addressed to the nurses since doctors are not available all the time. Even if they are, the protocol calls for nurses to be at the interface between doctor and patient. In the simplest of terms, nurses facilitate effective healthcare by significantly sharing the burden with the doctors so they can better do their job.

If this is not enough to convince one of the importance of nursing, think about what would happen if they didn’t exist?

 

The Rates of Human Aging Between Young and Old

It appears that some of our younger generation are aging faster than expected. At least that is the consensus from a number of research studies that have been done.

Let’s take a look at these studies and see if we can make sense of this phenomenon. 

Participant Studies

According to the Los Angeles Times, in “Science Now”, “humans age at remarkably different rates. Additionally, we start aging earlier than one might guess,”. Also, in a study published in the Proceedings of the National Academy of Sciences, a 954-participant research program revealed that “young adults already showing signs of aging aren’t just prematurely old; they seem to be getting older faster than” other people. 

The participants who were “taking part in a lifelong medical study since they were born at a hospital in Dunedin, New Zealand in 1972 and 1973.”, as per NBC News. Investigators “came up with a batch of 18 measurements they believe correlate with aging,” including “medical measures of their lungs, their kidneys, their livers, their hearts, their immune system and even the integrity of their DNA.”

The report showed that at age 38, participants’ “biological age’ – the state of their organs, immune system, heart health and chromosomes – ranged from as young as 30 to as old as 60.” People whose biological age was older even looked older. In addition, “the fast-agers showed worse balance and poorer motor coordination, and reported having more trouble with tasks such as climbing stairs or carrying groceries.” The report noted that, according to the National Institute on Aging, among others, provided support for the study.

Why Is This Happening?

There is conjecture that this might be due to younger people being more fixated on computers and computer or office jobs than exercise; although many do exercise and go to the gym, they are compromised by the eight-hour daily sit down at the office.

Then there are the game junkies who play nonstop for hours each day. Playing video games for extended amounts of time can inhibit their perspective on life as well as their bodies. Parents should be aware of the amount of time their kids are on the computer playing games and consider consequences if they are neglecting other things like doing homework or studying for a school exam. Video games are a good escape but too much can do wonders for their fingers but not much else.

As mentioned, there is no concrete evidence yet, but common sense does work its way here since lack of exercise can accelerate health issues or even cause the creation of issues that may not have existed if the person was keeping fit.

As the term sitting is the new smoking explains, staying off your feet for an extended amount of time on a daily basis can increase blood pressure, weight gain, abnormal cholesterol levels and a possible increased risk of death from cardiovascular disease or cancer.

How Do We Control Excessive Sitting?

Every 15 or 30 minutes, get off your chair and walk around the office. If your office is small, go outside and take a brisk walk. Does your company have a gym? If yes, take advantage of it! Or why not try going to the gym before you get to work? These suggestions might be a little premature at this time since we are in the COVID era, so we suggest calling your local sports club and find out their current rules, as some states are more lenient than others, which is dependent on the infection rate. 

There are also new devices that allow you to stand while working on the computer. You can adjust the stand to a height that is comfortable for you.

Summary

Man Riding BicycleBesides making sure you get that blood running through your body at a healthy rate, make sure you are eating the right foods as well. All these components add up to a healthier lifestyle and one which will help you deal with the constant sit-downs at your office.

And you game addicts – wake up and realize that getting a heart illness at an early age is not worth creating that fantasy empire or getting an extra kill in a military war game. But if you must, let that blood run through your legs and stand up for the win!. 

 

 

 

How the Eyes Work

Let’s take a look at our eyes (pun intended).  One of our most important senses, it contains an array of intricate parts that comprise the materials and intelligence for us to see. From one part to another, it’s like an assembly line of light. As the light passes through each component, the image that the eye sees gets more focused and adjusted for brightness or darkness. 

The Parts of the Eye

Your eyes consist of numerous parts. Let’s focus on the main ones, which are the cornea, iris, pupil, lens, vitreous, and retina. We’ll start with the basic phenomenon of light entering the eye. What’s the first part in which the light hits? 

The Cornea

The cornea is the front part of the eye. It is transparent and dome-shaped. Its function is to help the eye focus. Since it is transparent, you won’t notice it if you look in the mirror, but it is there. You could think of it as your window to the world.

The Iris 

Illustration of the Anatomy of the EyeBehind the cornea is the iris. Now, this component is very visible, as it is your eye color. So, if you have hazel eyes, it is the iris that you are looking at.

The iris’s function is to control the amount of light received from the cornea. It is a regulating mechanism that knows when to shrink the pupil, which is behind the iris or when to widen it, in proportion to the amount of light that comes in. The regulating mechanism is a muscular component that controls this. If the iris is not working correctly, you will see too much brightness or not enough light, which, of course, will inhibit what you usually see.  

The Pupil

The pupil is a dark opening situated in the focal point of the iris that permits light to strike the retina. 

For those among us who are photographers, you will probably be interested in this analogy that you can think of the pupil as the lens aperture (how much the lens opens) and the iris as the F-Stop (the mechanism that controls the aperture). So when light hits your eye, it passes through the cornea and is intersected with the iris. The iris determines how much of an F-Stop setting is necessary and then that amount of light is passed to the pupil, which accepts that amount of light.

The Retina

The retina converts the surrounding image into electrical impulses. Like camera film or, for our millennial generation, a light sensor in a camera adjusts for the proper amount of light, then transfers this information into electrical signals that it sends to the brain. 

More specifically, it converts light into electrical signals and then sends these signals to the brain for visual recognition. Using our camera analogy, it would be similar to the camera sensor, which acts as the CPU to determine the amount of light, colors, and dimensions and then translates that to neural impulses. 

Just like the neurons in the brain, the retina contains layers of nerve cells interconnected by synapses. Some of these cells are light-sensing cells and are called photoreceptor cells, which convert light into electrical signals. 

There is an outer layer of the retina called pigmented epithelial cells and contains two types of cells called rods and cones. Rods process dim light and cones process a well-lit environment, as well as determining color. 

The following video explains how the eye works in a nutshell.

Summary

Our eyes are complex organs that convert the images that are sent to them into a visual perception that we humans can understand. We only brushed upon the basics of how our eyes work, but our intention was for you to get a general understanding of how they function and how they convert the light that hits our eyes into the objects that we see. See what I mean? 

 

 

 

Recovering from COVID-19 – What to Expect?

Female doctor with mask on holding a globeNow that the President of the United States has been infected with the COVID-19 virus, people are more than ever taking a closer look at what would happen to them should they get infected. Of course, the ‘cocktail’ that is being used for the president is most likely not what the average citizen would receive, so we will be concentrating on the commercial recommendations from the doctors and scientists for the general public.

If you look at the numbers, as of September 24, 2020, more than 23 million people have recovered from COVID-19. But the road to recovery is not always the same. Since COVID-19 affects people differently, every coronavirus patient recuperates at a different pace. Moreover, their recovery rate depends on the severity of their symptoms and a prior history of their medical conditions.  

In this post, we will be focusing on people that are considered healthy (those that are not immune-compromised, have existing illnesses or are seniors). Discussing recovery for people in the compromised category demands a completely different article of which we will post soon. For people in the healthy category, you will find information about what to expect if you recovering from the COVID-19 and some of the essential things that you need to know once you have recuperated from the infection. 

Note: Even if you are healthy, you may still bear the effects of those that are compromised. There are no guarantees when it comes to COVID-19. At least not yet! Additionally, the information provided here is for general information only from reliable sources, but is not based upon any scientific data. For more information on the information provided on this website, please see our disclaimer. 

Recovering from COVID-19: What to Expect?

a-male-patient-smiles-while-holding-the-hand-of-a-friendPerhaps, the most critical factor that affects the recovery process is the severity of its symptoms.

How quickly and how well you recover depends on whether your case is mild, moderate or severe.

Let’s look at each of the three scenarios and find out how the recovery looks. 

In Case of Mild Symptoms 

According to statistics, 80% of the people who get infected by COVID-19 experience mild symptoms. Moreover, a certain percentage of patients are asymptomatic, which means that they do not experience any symptoms. However, this does not mean that they are entirely healthy.

In mild infections for healthy people, the average recovery time can take up between seven and ten days, maybe more, depending upon how your body reacts to recovering. In general, you can expect the recovery to be similar to other viral infections, such as the common flu.

And while the symptoms may completely subside within two weeks, patients may continue to experience weakness and shortness of breath (especially after performing the strenuous activity) for another few weeks. However, these after-effects can improve on their own. Therefore, a healthy diet, mild exercise and a lot of rest are generally recommended for almost every patient infected by COVID-19.

In case of Moderate Symptoms 

In case of moderate symptoms, you can expect the recovery process to be longer compared to those with milder symptoms. Since moderate symptoms may warrant ER visits and possible hospitalization, you should keep in mind that these conditions may persist for a period. While the average recovery period is two weeks and the fever usually subsides within that time, you still may have a cough, fatigue and shortness of breath which could continue for several more weeks.

An infected person with moderate symptoms can take up to six weeks to completely recover.

In Case of Severe Symptoms 

Severe symptoms of COVID-19 mean that the infection has affected the lungs which have led to the development of pneumonia or an autoimmune response to tackle the virus that has damaged the lung tissue, a condition known as acute respiratory distress syndrome (ARDS). Therefore, the patient would require hospitalization and intensive care with the possibility of a ventilator as well. 

In that case, the recovery process can take anywhere from a few weeks to a few months or longer. And if you spend time on a ventilator, you can expect a lot more time when it comes to recovery. Once off the ventilator, you will need a lot of time to regain your strength. Moreover, a lot more time will be required for the pulmonary function to return to normal.

An important thing to remember is that a person with severe symptoms may continue to be contagious for a while. While the average recommended period for isolation is two weeks, this does not apply to people with severe symptoms. Therefore, it is highly recommended that even if you have recovered from severe symptoms, you should continue to wear a face mask and repeatedly wash your hands using soap and water. This will protect those around you and keep you safe as you recover from this viral infection.

Recovering from COVID-19 with a Prior History of Medical Conditions

According to statistics, people with a prior history of medical conditions, such as diabetes, hypertension and cardiac problems, experienced more severe symptoms than those who do not have any such medical condition. And since such people experience more severe symptoms, it is only natural to expect a longer recovery time. The risk factors highlighted below can significantly lengthen your recovery period. 

  • Age 60 and more 
  • A history of disturbed lipids (such as high cholesterol and triglycerides) and cardiac problems,
  • Diabetes
  • Hypertension
  •  Chronic Kidney Disease
  • Cancer or
  • Any other person in an immunocompromised state (whether due to recovery from an infection or cancer, organ transplant or any other medical condition that can weaken your immune system) 

Long-term Impact of COVID-19

So far, there is limited information on the long-term impact of COVID-19. Since the infection affects the lungs, it is expected that patients who have recovered from COVID-19 may develop lung and heart diseases in the future. Moreover, some research in preliminary stages indicates that the infection may have an impact on the brain as well. However, a lot of research is required, and in the next five years, the medical practitioners will be in a better position to figure out the long-term impact of COVID-19. One thing is for sure that even patients with mild symptoms complain of fatigue, which is considered a long-term impact of the infection.

Can I Get Infected Again?

The answer is possible. Research indicates that it is possible to get infected with COVID-19 for a second time months after recovering from the infection. However, according to statistics, those who are infected again experience milder symptoms. This is because the immune system is better equipped to deal with the virus when it attacks the body for the second time.

How Can You Help Others When You Have Recovered? 

In most cases, people infected with COVID-19 have a smooth recovery. And with a recovery rate of 99%, there is a good chance that you will recover without any significant problems. Since there is no vaccine yet, you can help others once you have recovered. Health professionals are using a blood-transfusion therapy, called convalescent plasma therapy, to treat critically ill COVID-19 patients.

The plasma is drawn from the blood of recovered patients  and transfused into critically ill COVID-19 patients.  Since the plasma is rich in antibodies, it can be used to help another person fight COVID-19. While there is no guarantee that the plasma therapy will always work, it is one possible way to save lives when you have recovered from the disease. 

Bottom Line 

When fighting against COVID-19, always remember that every patient has a unique recovery process. But when you keep your spirits high, the road to recovery may become a lot easier and better. And once you have recovered, you have the power to treat others, so make sure you get well soon and help others fight COVID-19 more effectively.

Components of the Brain

Neurons in the Brain
Neurons in the Brain

We have previously discussed the hundreds of trillions of cells, AKA neurons that exist in our brains. Just think about that for a second (or two). Now let’s see what holds all these nerve cells together!

What is the Brain Made of?

There are so many additional details to this piece of ugly gray matter that we haven’t spoken about yet, so now let’s dive into it.

By now, you should have a pretty good idea of what the neurons do, but what causes these nerve cells to react? Well, our sensors (sight, smell, hearing, touch and taste) have a lot to do with this. 

When we sense something, our brain amasses the messages in a manner that has meaning to us; in other words, the nerve cells get to work in order to make us understand what just happened. If you touch something that is hot, say grab a coffee cup from freshly made coffee, that instinct of touch is translated into ‘neuron language’, where millions, perhaps billions of nerve cells get together in our brain to tell us that this item is hot. Of course, this happens instantly to us. Thousands of times faster than it took you to read this paragraph. 

The Components of the Brain

So now that we can identify how the brain translates information, what are the different parts of the brain and how do they work? 

There are three parts. The cerebrum, cerebellum, and brainstem.

The Cerebrum

The Cerebrum Illustrative View

The cerebrum is the largest part of the brain. Its function is remembering, problem-solving, thinking and feeling, and movement. The cerebrum is located in the lower back area of your brain.

There are two parts of the cerebrum called the right and left hemispheres, sometimes referred to as the right or left side of the brain. Interestingly enough, each side of the cerebrum controls the other side of the body, so if you have a stroke that comes from the left side, it will be the right side (namely your arms and legs) that will be affected.

The left cerebrum controls speech, comprehension, and math. A more generic way to label the left side of the cerebrum is that it focuses on logic or problem-solving. The left hemisphere is the dominant side for about 92% of the population, which is why so many people are right-handed.

For all of you Star Trek fans, ever wonder how Mr. Spock’s brain is assembled? He is of course a Vulcun whose species focuses specifically on logic, so is his left cerebrum more abundant (and the right side less abundant) proportionally? Or maybe he doesn’t have a right hemisphere at all? After all, he didn’t seem to be that great in music. 

The right hemisphere controls creativity, art, and artistic and musical skills. Does that mean legends such as Leonardo da Vinci, Auguste Rodin, Irving Berlin, Michael Jackson, and Frank Sinatra had larger right hemispheres or that they just used that part of the brain more often? 

Of course, when it comes to scientists, we’d like to deduce that Albert Einstein used his left hemisphere most often, but it is not as simple as that.

Neurons in the Brain

In an excerpt from Discover Magazine,

“Those who would explore Einstein’s brain are well aware they’re treading potentially controversial ground. Nevertheless, they believe they’re on to something. In 1985, neuroscientist Marian Diamond of the University of California, Berkeley, reported the Einstein brain had extra cells called glia. These cells support the “thinking” neurons in the left parietal lobe, an area above and behind the left ear involved in spatial relations and mathematics. She speculated that this “might reflect the enhanced use of this tissue in the expression of his unusual conceptual powers.” Seven years later, a researcher in Osaka, Japan, suggested a link between that higher glia-to-neurons ratio and Einstein’s purported dyslexia.”

Cerebellum

The cerebellum resides in the rear of the brain. Its functions involve coordinating voluntary movements such as motor skills, maintaining posture, equilibrium, and balance. 

If the cerebellum is not performing correctly (e.g. brain injury, poorly developed, stroke, born with a defect) can result in numerous issues; such as asynergia, which is a motor coordination illness, dysmetria, makes it difficult to use your hands (e.g. trying to pick up a cup of coffee) and Parkinson’s Disease, which is a neurodegenerative disorder and involves tremors in the hands as well as compromised functionality in other parts of the body.

Brain Stem

Appropriately named because it connects to the spinal cord and resides in front of the cerebellum. 

There are three major parts to this part of the organ:

Midbrain

The midbrain processes visual and auditory information.

Pons

This is the largest part of the brain stem. It’s located below the midbrain. It’s a group of nerves that help connect different parts of the brain. The pons also contains the start of some of the cranial nerves. These nerves are involved in facial movements and transmitting sensory information.

Situated beneath the midbrain, it is the largest part of the brain stem. It’s a gathering of nerves that interface with other parts of the brain. The pons is also part of a segment of the cranial nerves. These nerves are engaged with facial developments and sensory data.

Medulla Oblongata

Resides in the lower part of the brain. It acts as the control center for the function of the heart and lungs. It helps regulate many important functions, including breathing, sneezing, and swallowing.

This is where the heart and lungs are controlled and as such, it controls breathing and other heart/lung functions.

Conclusion:

This brief but rather definitive article gives some insight into how are brain functions and how these functions correspond to other parts of our body, so the next time you think, walk, talk or catch a baseball, consider how your brain made this happen and never take these motor skills for granted since there are some folks who are not as fortunate those with parts of the brain that do function well.

Kill Coronavirus with These at Home DIY Soaps and Hand Sanitizers

Do this. Don’t do that. Dr. Fauci said do it this way. CDC said don’t do it that way. Politicians, oh how the politicians complicate the matter. One can lose their mind listening to all this news (or as some say, fake news, depending upon your particular point of view). Well, let’s try to break through all this confusion by providing some undisputed facts!

KEEPING THE LID ON COVID-19 OVERVIEW: WASH YOUR HANDS!

Keeping your hands clean with soap or sanitizer is one of the best protections against spreading the COVID virus. Photo by Mélissa Jeanty on Unsplash

In order to contain this disease, we should wash our hands for a good 20 seconds, but if you don’t have soap immediately available, use hand sanitizers and you should be carrying these cleansing items with you at all times. 

As we know, COVID-19 is a respiratory virus that spreads through our eyes, nose and throat. Often, this virus enters your body through your hands by touching an object infected and then touching your face which is a leading cause for the virus to get into your body. So make sure you wash your hands frequently. This will minimize your chance of catching infections. (Wearing a mask is also just as important!).  

If there aren’t any soap or hand sanitizers available, fret not. You can prepare antibacterial soaps and hand sanitizers at home. Here are a few simple ways to make them in next to no time. 

DIY Antibacterial Hand/Body Soap

Ingredients

  • Green soap – this is the most essential ingredient in this soap recipe. It is made from glycerin and vegetable oils and acts as a superb disinfectant. 
  • Distilled water – if not distilled water, use cold water. 
  • Neem oil – works brilliantly on dry skin. It restores moisture and enhances the skin.
  • Essential Oils (tea tree essential oil, clove essential oil, rosemary essential oil, clove essential oil, oregano essential oil) – use all or any of these essential oils for refreshing smell and skin nourishment and enhancement. 
  • Vitamin E oil (optional) – for extra skin nourishment. 
  • Optiphen Plus – this soluble acid helps preserve the soap solution for good.

Tools

  • Soap dispenser 
  • Hand or electric blender
  • Large mixing bowl

Directions 

  1. First, transfer the distilled water in a large mixing bowl. 
  2. Add in the green soap, neem oil, essential oils, Optiphen plus and vitamin E oil (optional).
  3. With the blender, whip the ingredients until they combine well and become foamy. 
  4. Pour the content into a soap dispenser and tada! The soap is prepared for everyday use. 

Note:

  • Green soaps are easily available in stores. 
  • There’s no hard and fast rule when it comes to using the essential oils listed here. You can use any essential oil according to your preference.

  • 1 cup of 99% pure isopropyl alcohol 
  • 1 tablespoon of 3% of stabilized hydrogen peroxide 
  • 1 teaspoon of 98% glycerin
  • ¼ cup of sterile distilled water (or cold water) 

Tools

  • Measuring cup 
  • 1 pour spout 
  • Spray bottle(s) 
  • Clean spoon
  • A medium-sized container

Directions 

  1. Using the measuring cup, measure the alcohol, and pour it into the container with the pour spout. 
  2. Mix in the hydrogen peroxide.
  3. Add in the glycerin and stir the mixture using the clean spoon. 
  4. Now, pour in the water, making sure to measure it first. 
  5. Transfer the prepared mixture into a spray bottle. Shake well before use. 

 Note:

  • Keep in mind that when you mix the glycerin with alcohol, the mixture will be thick and it will take some time to mix everything together. 
  • If you prefer gel sanitizer, you will need to combine 1 cup of 91% isopropyl alcohol, ½ cup of aloe vera gel, and 15 drops of tea tree oil or any of your favorite antibacterial essential oil. 

Note: If you think that vinegar is a good disinfectant, be careful. Although it is a great cleaning agent, it does not kill many viruses or bacteria. Disinfectants, which vinegar is not, is the agent that will do the job when cleaning away surfaces that may contain viruses, so if you are shopping for disinfectants besides soap and sanitizer, make sure the item specifically states ‘disinfectant’. .

DIY Disinfectant Spray

How Your Brain Works – An Elementary View

Hey!

Did I catch your attention? How long did it take? What exactly happened that allowed you to register this thought? Well, now we are going to find out.

Previously, we discussed the elements of the brain. Now we are going to go a bit deeper to see how this cognitive process works! Are you ready? Make sure you have your thinking caps on!

Note: Be sure to read How the Brain Affects Our Behavior as a prerequisite to this article.

The Central Nervous System

TE-Nervous system diagram
The Central Nervous System

Your brain does not act alone. It communicates with your spinal cord to coordinate your body’s actions. How it does this is complex; however, we will keep it simple.

Similar to data that is communicated through the Internet, the central nervous system does the same thing within our bodies. It is an information processing system with many ‘wheels’ that regulate how we think and move. In other words, our brain coordinates with the other parts of our body so that all these components work in conjunction with each other.

For example, you decide to get something to eat because your brain has notified you that you are hungry, but who told your brain that you are hungry? Well, most would agree, that t would be your stomach. Now that you know you are hungry, you decide to walk to a restaurant, so your brain tells your legs to start walking. You open the restaurant door and, you guessed it, your brain just spoke to your hands. This process goes on 24/7, even when you are sleeping. 

Simple Cell Creatures

There are so many cells in the human body that it is almost as mind-boggling as the universe itself, but let’s see if we can make sense of it all.

When you look at a building, you look at it as one whole unit, never thinking about seeing it brick by brick. Now, what if we were to look at living organisms that way? Starting with the simple amoeba, we decide to look at it as cells or by each cell that puts it together; however, the amoeba is made up of only one cell, so we can’t do that with this fellow.

Let’s move on to more complicated creatures like tardigrades, which are tiny, almost microscopic animals that live in moist and watery areas. They are simple, but almost immortal creatures. They can live in just about any environment. Water, land, and even outer space, are very hard to kill (not sure why anyone would want to do that though).

With that said, these creatures have up to 40,000 cells, and this is our point. From the ameba to the tardigrade, there are 40,000 more of these tiny organisms in the tardigrade and that is what makes this animal look and live the way it does. But still, 40,000 is not a lot compared to the next species we are going to discuss.

Cells in the Human Brain

100,000,000,000 cells. That’s 100 billion! In comparison, this amount equates to 50 times more than the number of stars in our Milky Way galaxy. No wonder we have intelligence, although some could argue that premise :-).

Of these 100 billion cells, 86% are neurons, also known as nerve cells. These cells’ function is to transmit information from/to the brain and from/to the central nervous system. They do this by electrochemical means, which is the process where electrons move from one location to another. Yes, our brain cells have electrons.

When electrons move from one place to another, they are transmitting information, albeit, it is information that moves in extremely tiny amounts, but it is a transmission of information that is occurring. Neurons can transfer these tiny messages an inch or less or several feet, depending upon where the receiving neuron is located. 

What Neurons Are Made of

Cell Body AKA Soma  

This is the essential part of the nerve cell that contains all the necessary components needed for the cell to function. It is somewhat analogous to the heart in our bodies. The soma contains the nucleus, ribosomes (which build proteins, and mitochondria, the component which makes energy). Just like the heart, if the soma fails, then the rest of the cell fails with it.

Axon

Think of it as a pipe. The electrical impulse (message) moves down this pipe (or up). In scientific terms, it is the action potential that allows the messages to be projected away from the soma and travel down the axon where it is expelled through the dendrites.

There is an external material that the axons contain. Like a road that contains gravel and a road that is finally paved, some axons are covered with this material which is a thin layer of myelin sheath, while others do not have this sheath component and are called non-myelinated. 

The purpose of the myelin sheath is to allow the messages to travel faster, like a car traveling down a finally paved road in contrast to a non-myelinated axon (gravel road) where the message takes longer to reach its destination. In scientific terms, myelin helps to speed the transmission of the nerve impulses down the axon.

Myelinated neurons are those that are located in the peripheral nerves – neurons that are outside of the brain and non-myelinated neurons are the ones that are located within the brain and spinal cord. Indeed this makes sense since those neurons that are outside of the brain have a longer distance to travel than those that are millimeters away from each other inside the brain.

Dendrites AKA Nerve Endings

Like an octopus’s arms, they branch out from the end of the axon to make electrical contact with the destination neuron. 

If you are familiar with electronics, the transmission of the messages is actually the movement of electrons from one cell to another.

Conclusion

Neurons in the Brain
Neurons in the Brain

The nerve cells communicate or talk (send information) to other nerve cells via a series of electronic pulses that originate in the nucleus (sona) and proceed through the axon to the dendrites where they are picked up by another neuron. Thus, we have the processing of information that goes on continuously. 

The speeds at which the receptors of the dendrites receive and transmit information have not been scientifically proven to complete accuracy; however, scientists estimate that the unmyelinated nerve cells in this gray matter that we call the brain travel around 11 inches per second. So to keep it simple for us human mortals, we can say that the speed of a message is instantaneous, at least within our heads. 

Putting this all together, the processing of information in the brain of, say, deciding to turn on the TV can involve hundreds of thousands of nerve cells and be equated to just one thought; thus, neurons are the mechanisms that transmit our thoughts! What do you think of that?

Impact of the Coronavirus Pandemic on the Poor

COVID-19 has taken the world into its merciless grip, causing illnesses, untimely deaths, and global despair. Everyone – whether poor or rich – is living in constant fear due to the existing pandemic. However, the deadly virus has proven cruelest to poverty-stricken people and families. 

According to the International Labor Organization (ILO), four out of five people have been impacted by workplace restrictions around the globe. The organization further stated that approximately 1.6 billion temporary employees are at risk of losing their livelihood completely. These low-income families face absolute hunger and poverty now. They can’t stay at home despite the lockdown, as they have to look for temporary work for their next meal. We followed the stories of 4 people around the world to explain to us how the coronavirus pandemic has affected them and their families.

New Delhi, India

Since the Indian government went into a shutdown to flatten the coronavirus curve, stories of hunger deaths and suicides have emerged. A large percent of the Indian population has no access to work, food, and are emotionally unstable since the lockdown has taken place, forcing them to commit suicide in their homes. 

For example, about 80 people killed themselves due to the fear and loneliness of being affected by the life-threatening virus. Some coronavirus deaths were also reported due to exhaustion and hopelessness caused by traveling long distances for rations and facing violence while collecting them. 

Also, reportedly, a woman jumped off in the Ganges River along with her five children because of starvation; and an Indian migrant also hung himself after being severely wracked by hunger and poverty during the shutdown. 

Jakarta, Indonesia

Restaurants across the world have been hit the most due to the coronavirus pandemic in comparison to other businesses. Lockdown restrictions have ensued people to quarantine and avoid public places at all costs. Many restaurants can’t afford to stay in business with a lack of regular customers. As a result, many chefs and waiters have lost their jobs. 

One such case is of Budi Santosa, who was a cook in a Chinese fast food restaurant in Jakarta, Indonesia. The 32-year-old man is the sole breadwinner of his family. He has a wife and two young children. So, he worries about them the most. With him and his wife forced to stay at home, Santosa is worried that they won’t have food to eat and will die out of hunger. However, poor circumstances have not deterred Santosa from going out and finding work. For the time being, he has borrowed money from his friends to make ends meet.   

Nairobi, Kenya

Nairobi Kenya is counted among the world’s poorest cities. The living conditions over there are below par and have gotten worse since the pandemic. Stories of hardships are countless in Nairobi. 

The one that touched our hearts the most was Judith Andeka – a middle-aged mother of five. She lost her husband two years ago. Since then, she has been earning her livelihood by washing clothes. Before the pandemic, she could earn about $2.50 – $4 per day. But now, she is out of work with the looming pandemic threat. Many people in Kenya’s capital city have lost their jobs and can no longer afford her services. Even if they can pay, they no longer want Andeka to touch their clothes because they are worried about catching the virus. 

Owing to her poorest state of life, Andeka has sent her five children off to live with her relatives until she finds a sustainable job. What’s more is that Andeka suffers from the worst kind of treatment at food distributions. Police officers and law keepers often use sticks and tear gas to keep back large crowds from hovering over the place. She fears losing her few valuable possessions, but despite that, she has to step out and find work daily.  

Islamabad, Pakistan 

As the coronavirus outbreak has spread in this South Asian country, affecting hundreds and thousands of people, a daily wager – Shireen Khan – in the capital city of Pakistan shared that he has not earned a single rupee since the pandemic has forced the countrywide lockdown. The daily wager sits every day by the road in the hope someone will stop by and offer him work. 

The 46-year-old man does this daily out of hunger and illness. He has been suffering from typhoid for over five or six months and needs money for the treatment. Sadly, this is not just a story of Shireen Khan, but a story of hundreds of daily wagers like him who are struggling to find work and fend for themselves in these tough times. 

Final Word

The global economic crisis due to the coronavirus outbreak has worsened the lives of many lower-income people around the world. They are living in constant emotional and financial instability due to the lack of proper food, housing and employment. Specific focus is needed to reach out to the poor and provide them with the necessary means so they can afford the basics. Governments and NGOs should curate actionable plans and programs that can ease the financial hardships of the poor in these COVID-infested times.

How to Stay Safe as an Essential Worker During a Pandemic

Female doctor with mask on holding a globeDo you know the saying “don’t bring your work home with you”? Well, it is a healthy way for you to remember that you should keep work disconnected from your personal life. 

While it has been traditionally used to make sure that you take a break once in a while, it has definitely taken a new meaning during the pandemic. Essential workers who are required to continue working during the coronavirus outbreak need to take extra precautions to ensure that their work does not affect their personal life, especially their health. 

Essential workers are at an increased risk of getting infected with COVID whenever they come into work. They also risk-taking the virus back home to their families after each day. It is a concern that can increase the stress you may already have because of the pandemic. There are employees like doctors, nurses, delivery persons, grocery store workers and more that are at increased risk of infection. 

This is why it is so important for all first responders ensure they are taking extra precautions to secure their safety. With that said, if you are one of these heroes, you may find the following tips helpful. 

While at Work 

Man working on computer wearing a maskHere are some tips that can help you stay safer while you are at work. 

  • Keep personal items separate from your workstation. Items like your rings or cell phones should be kept in the break room, locker or office. This will decrease the chance of any of such items being contaminated. Before you use any of these items again, make sure that your hands are properly washed and sanitized. You should also sanitize these items at least once every day.
    .

  • Clean Your Work Area

    Don’t take for granted that the cleaning staff that comes in at night did a thorough job of disinfecting your office, specifically your desk and the items on it. Clean it yourself. Use anti-bacterial wipes or put soap and water on a cloth and wipe down the areas you use most, even places you may just rest your arms or hands.

  • Check Your Inner Feelings

    As a first responder, especially if you are in the healthcare industry, it can feel quite overwhelming. Pause for a moment or two to recollect can be important. Keeping a straight and clear mind will make sure that you don’t make any mistakes that can lead to you getting infected.

  • Maintaining Social Distancing

    While it can be hard to maintain a good six feet away from everyone at all times, you should still do your best to try to do just that. If you are working in an indoor space, such as a grocery store, it can increase the risk even more. This is why you may want to talk with your employer to make sure that not too many people enter the store at a time so that there isn’t crowding in the aisles.

  • Wash and Sanitize Your Hands Frequently

Your hands are the biggest cause of transferring the virus to your face. You may be coming in contact with plenty of contaminated surfaces, but if you regularly continue to sanitize and wash your hands, you will be safer.

You should carry a sanitizer around and regularly use it during the day. After your shift is done, you should make sure to wash your hands with water and soap thoroughly.

  • Face Covering

Having a mask on can greatly decrease the risk of infecting another person in case you are asymptomatic.

Masks are the best shield against the virus since they stop your hands from touching your face too. 

While At Home 

Keeping the germs away from the home is also important. Here are some tips you can follow to ensure that you stay safe as an essential worker during a pandemic and so does your family: 

  • Leave a pair of shoes near a door that you can wear. A place should also be set up to isolate anything you can’t wash and don’t want to take into the house. 
  • Remove your clothes and place them in a hamper by your door. You should use a garbage bag to line the hamper and wash your clothes at once using the warmest temperature possible. 
  • Wipe the phone down or any jewelry you wore during the day
  • Sanitize and wash your hands frequently
  • If you work in a high-risk environment or have people who are at high risk in the home, you should shower immediately too. 
  • Make sure to drink, sleep and eat with the essential nutrients so that your immune system is never compromised 
  • Monitoring your health is also very important. Taking your temperature twice a day to make sure that you don’t have a fever is vital. Do not go to work if you have a fever or you don’t feel well.
