Sleep eight hours every day. Exercise.
There are several truisms about staying healthy that we sometimes do not use due diligence in ascertaining whether the advice given to us is correct. Then there are the old wives’ tales, passed down from one generation to another, that frequently disregard the difference between fiction and fact. Below, you’ll get a list of 10 of the most frequent health clichés out there.
Weighing in at just over 1.4 kilograms (3 pounds), the human mind is home to almost 100 billion neurons. They transmit information to one another across gaps called synapses, where the mind has almost 1 quadrillion.
The mind is sectioned into three main parts-the cerebrum, the cerebellum, and the brain stem. The cerebrum composes roughly 85 percent of the organ and is responsible for a lot of the higher-level operation we associate with being human. Seated below it, you will discover that the cerebellum, which controls basic balance and coordination. And finally, you’ve got the brain stem.
Wouldn’t it be amazing if all of this processing is just using 10 percent of their brain’s bandwidth?
Alas, this “reality” is completely wrong. We’re not certain in which the claim that we only use 10 percent of our brains came out, but it seemed to percolate from the late Victorian age. From the late 1890s, Harvard psychologists William James and Boris Sidis employed the latter’s wunderkind (his IQ was almost 300) as evidence that all humans have to have the capability to be smart. We just need to try harder.
Further research at the onset of the 20th century discovered that rats with cerebral damage could be retaught particular tasks. This was used to reinforce the already weak case that our mind is full of untapped potential. Regrettably, this factoid is totally ridiculous with no basis in modern science. Just reading this paragraph uses over 10 percent of your mind. Oh well.
After consuming a particularly large piece of bubblegum, a lot of you might remember being horrified to hear that your digestive tract could spend the next seven years trying to digest it. If your seven years is not up yet, you might be relieved to learn that this “reality” is complete crap.
Even though the origins of the myth are elusive, it’s borne out a comparative truth about chewing gum.
While it’s not a good idea to swallow your chewing gum, what happens to it is not all that exciting. Excess ingredients like sweeteners could be digested, but the majority of the gum is an elastomer which gets moved through your digestive tract without being broken down. Then the gum comes out the other end through the excretory system and is normally unscathed.
Otherwise, they leak like crap down a stream, right out the other end.
As if puberty, high school, and those teenage years are not hard enough, lots of us grew up learning that our chocolate ingestion had a causal connection with breakouts. Pretty awful that chocolate, the 1 thing that makes adolescence bearable, lights up your face with nasty zits.
Eating chocolate won’t allow you to break out. However, eating foods high in sugar and fat can raise the body’s natural sebum production, making your skin oilier. What’s more, those unhealthy foods contribute to high levels of skin inflammation.
However, will chocolate-or any food for this matter-make your skin break out? Eating high levels of fatty foods will definitely trip up your blood glucose, which can indirectly impact breakout levels. However, no single food item is the golden ticket to preventing teenage pimples.
To be honest, carrots are amazing sources of beta-carotene, an inactive retinol that’s converted into vitamin A during digestion. Vitamin A provides all kinds of benefits to the body, for example, protection of eyesight.
However, does it really enhance one’s nighttime vision?
No. The British Ministry of Information conducted a campaign during World War II that indicated pilots in the Royal Air Force were eating huge amounts of carrots, describing their uncanny ability to shoot down German fighter pilots under the veil of darkness. Truth is, all of the carrots in the world could not give you the gift of nocturnal sight.
It is unlikely that German intelligence bought into the notion that British pilots were fueled by high-octane carrots.
We hate to be the ones to break it to you, but you are not likely to get night vision anytime soon.
We’ve Five Senses:
This one ought to be simple, right? The belief that people have five senses dates back to the time of Greek philosopher Aristotle, who was the first to identify the five distinct senses of the human body.
Yes, these are just five of your senses. But they are not the only ones.
Let us start with the fundamentals. What’s a “sense”? Well, it is something with a detector that could perceive a given stimulus. Every sense is triggered by a special phenomenon.
In actuality, the sensation of touch is truly much more complex than simply a single sensation. Many neurologists break down “touch” into divergent senses, including perceptions of stress, fever, and pain.
Based on whom you ask, people have as many as 33 senses. These include some senses, such as blood pressure and equilibrium that you knew you had but did not count as a “sense” So, next time someone says they have a sixth sense, you could respond by saying you’ve 33. They might not know exactly what you mean by that, but you will know!
A lot people can remember being taught, by a biology teacher no less, our capacity to roll up our tongues was straightforward genetic fate.
In fact, it is not that easy. Unlike a number of these body myths, we’ve got a fantastic idea from where this one came. In 1940, American geneticist Alfred Sturtevant released a study that concluded that your tongue-rolling ability was a hereditary characteristic according to a dominant gene.
But, Sturtevant’s exuberance over his finding was short lived. People realized quickly that there were identical twins where one can roll his tongue and another could not. Because of this, Sturtevant’s findings were quickly debunked, with the guy at the helm conceding defeat.
And yet, decades later in classrooms throughout the world, this falsehood has been spread anew. Now you know the truth, you can stop the madness from spreading the next time somebody unveils this unique parlor trick.
Between the fantasy that we only use 10 percent of our brains and the prevailing belief that we lose nearly all our body heat through our heads, it feels like our craniums can not catch a break. A prevailing theory on the origin of the myth: Scientists conducted research in the 1950s in which subjects were exposed to low temperatures and dropped a good chunk of the heat through their noggins.
The problem with this study is that the topics were bundled up in coats and only their heads were exposed to the elements. So yes, if each part of your body is insulated and your mind is not, you will lose a disproportionate quantity of body heat through your head.
However, more recent study finds that, all else being equal, an inordinate quantity of heat does not escape from your mind. [
So, treat your mind like every other part of the body. When it is cold, package it up and everything will be OK.
This “reality” about the human body is kind of creepy, is not it? Well, we are here to let you know that it’s not really correct.
Our bodies dehydrate rather quickly once we die. At these times, our skin begins wrinkling and pulls inward. Because of this, morticians will frequently snore corpses in lotion to keep them out of pruning up.
Arthritis can be debilitating or mild.
Obviously, if you’re able to stay away from activities associated with arthritis, you need to. For many health-conscious people, this includes a seemingly straightforward request-don’t crack your knuckles. However, we are here to tell you that cracking your knuckles does not make the list on your struggle to prevent arthritis.
That popping sound is connected with bubbles bursting on your synovial fluid (the substance that greases your joints).
Having said that, you still may want to give up the habit. Chronic knuckle cracking is connected to poorer grip power.
Shave Your Beard, And It Will Grow Back Darker:
Who has not heard this one? Not only will the hair grow back, we are told, but it will grow back faster and darker than before.
This is totally false. In actuality, we have known this is not true for quite a while. One of the earliest modern studies on the issue took place in 1928. The engaging men all shaved in precisely the exact same manner with the identical brand of shaving cream. Then their following new hairs have been examined for increased rates of expansion.
A whole lot of this myth comes down to understanding. As our hair grows back, we might be affected by our preexisting biases. Additionally, when you wax or shave hair off, it is like chopping down a tree and leaving the stump.
Regrettably, any changes in growth rate could result from underlying hormonal changes. But otherwise, it is all in your head!
