4 Major Factors That Affect Drug Absorption in the Body 

In order for any drug to do its intended job — relieve pain, kill an infection, etc. — it must be absorbed by the body. This is a process we often take for granted. We simply swallow a pill or receive an injection and wait for the drug to begin working. But there are many factors that can affect drug absorption within the body, some of which may extend your wait time to feel better and become healthier. Drugs are generally made up of both active and inactive ingredients. The active ingredients are what actually treat the condition of concern (pain, etc.), while the inactive ingredients, such as the cellulose that makes up a capsule’s outer shell, simply make the drugs easier to swallow. Absorption involves the body breaking down the drug, which separates the active ingredients from the inactive ones and enables the active ingredients to enter the bloodstream. Only then will you begin to benefit from the drug’s effects.

What Is Disease X and How Could It Change the World?

From the everyday uncertainties of choosing what to have for dinner to pondering the mysteries of life and death, our daily lives are riddled with anxieties that add unnecessary stress. But one fear in particular has loomed since the outbreak of COVID-19 in 2020: the dread of the next major, potentially catastrophic disease. Could it eclipse the unforgettable impact of COVID-19, which has claimed over 7 million lives worldwide? This mysterious threat, referred to as “Disease X,” has gripped the world’s imagination. Scientists and researchers across the globe are working tirelessly to prepare for it. Yet, how do you prepare for something when you don’t know what it is or how it infects people?

How Does the Body React to the COVID-19 Vaccine?

First appearing in China near the end of 2019, COVID-19 spread to North America and Europe by February 2020. By November 2020, two major pharmaceutical manufacturers had developed vaccines that were shown to be about 95% effective, which means vaccinated test subjects were 95% less likely to get COVID-19 than unvaccinated ones. The U.S. Food and Drug Administration (FDA) approved these vaccines for use within about a year of their inception. Prior to this, the shortest time in which a vaccine had been both developed and FDA approved was four years: for the mumps vaccine, introduced in 1967. At time of writing, there are three primary vaccines in use in the United States, generally known by the names of their manufacturers: Pfizer, Moderna and Johnson & Johnson.

What Organs Can You Live Without?

Our organs keep us alive, individually and in combination with other organs. There are about 78 organs in the human body, and each performs one or more vital functions. But do we really need all of those, or are there organs we can live without? As it turns out, we don’t exactly need all of our organs in order to survive. Let’s look at a few “unnecessary” organs, their purpose and why you can live without them. Appendix What It Does The appendix is somewhat of a mystery organ, as doctors and scientists aren’t 100% sure of its purpose. One common theory is that this little appendage to the large intestine is where the body stores good bacteria. It may also assist our immune system.

High Altitude: How Our Bodies Adapt

Whether you’re climbing a fourteener or just visiting the Mile High City for a week of recreational fun, one thing is for certain — both locations are a lot higher than sea level. But what’s the magic number that dictates when you’ve reached a high altitude?  The sweet spot is anywhere between 4,900 to 11,500 feet. If you go higher, you’ve reached the even more elusive (and slightly less oxygenated) very high altitude. So, while you’re sipping that CBD-infused latte in downtown Denver, it may not look or even feel like you’re on top of the world. But if you’ve only just arrived, we’re willing to bet that you might notice one or two of the side effects of being in a high-altitude location, like dizziness, headaches or nausea.  So why do we face these occasional uncomfortable symptoms and how do our bodies adapt to such a drastic change in height? In this article, we’ll break down how we acclimate to high altitude, what altitude sickness is and how to prepare for your next high-elevation getaway.  How Does Your Body Adapt to High Altitude? When you arrive at a high-altitude location, it would be wonderful if you could snap your fingers and bam — instantly adjust your body to its new environment

What Happens If You Don’t Get Enough Sunlight?

From sunburns and dark spots to more severe long-term consequences like skin cancer, you may be all too familiar with the potential repercussions of enjoying one too many beach days without sunscreen. And while it’s likely that your parents discussed the negative effects of having a little too much fun in the sun, they probably never took the time to go over what happens if you don’t get enough of it. The sun’s potentially damaging UV rays are the very same ones that provide your body with a natural form of vitamin D: an essential nutrient that keeps your bones healthy, reduces inflammation and supports your immune health and metabolism. But what happens when you’re not receiving enough sunlight? While it’s safe to say you won’t turn into a vampire, it is possible to experience some less-than-pleasant effects. In this article, we discuss the potential impacts of not getting enough sunlight and how much sun you actually need.

The Role of Bacteria in Gut Health, Digestion and Immunity

What comes to mind when you think of bacteria? Infection? Illness? While these ailments are often associated with bacteria, not all species of bacteria cause harm. Some are actually quite beneficial, and understanding how these microorganisms operate will make you feel much better about knowing that they’re alive inside you right now.  Bacteria are tiny organisms — living things — that exist within the bodies of humans and animals and in just about every environment on the planet. To give you an idea of just how small bacteria are, compare these single-celled microbes to the average adult human male, who is made up of more than an estimated 37 trillion cells. Despite their microscopic size, bacteria have the potential to do a great deal of harm or good within our bodies.   What Is Gut Flora?  Our digestive system (or gastrointestinal system) is home to five different types of bacteria, each of which contains multiple bacterial species. Bacteria are an important part of our flora, or the organisms that live in our bodies
