Eat your vegetables. Sleep eight hours a day. An exercise.
There are so many truisms about staying healthy that we sometimes do not use due diligence in determining how much we give advice. Then there are old wives. stories transmitted from one generation to another, which often ignore the difference between fact and fiction. Below you will find a list of the 10 most common health clichés. None of them are right.
We use only 10 percent of our brains:
Weighing just over 1.4 kilograms (3 pounds), the human brain is home to nearly 100 billion neurons. They transmit information to each other through intervals called synapses, of which the brain has almost one quadrillion.
The brain is divided into three primary parts - the brain, cerebellum and brainstem. Cerem is about 85 percent of the body and is responsible for most of the higher work that we associate with being human. Sitting below, you will find the cerebellum, which controls basic coordination and balance. And finally, you have a brain stock. Connected to the spinal cord, the brain controls most of your automatic functions, such as breathing and digestion.
Would it be unbelievable if all this processing used only 10 percent of the bandwidth of the brain?
Alas, this “fact” is completely wrong. We do not know where the claim came from that we use only 10 percent of our brain, but it seemed to leak from the late Victorian era. In the late 1890s, Harvard psychologists William James and Boris Sidis used the last wunderkind (his IQ was almost 300) as proof that all people should have the ability to be so smart. We just need to try.
Pretty funny, right?
Further research at the beginning of the 20th century showed that rats with brain damage can be assigned specific tasks. This has been used to reinforce the already weak case when our human brain is full of untapped potential. Alas, this factoid is completely ridiculous, without foundation in modern science. Just reading this paragraph uses more than 10 percent of your brain. Well.
It takes seven years to accumulate a piece of gum:
After swallowing a particularly large piece of bubble, many of you may remember how terrible it is to hear that your digestive tract will spend the next seven years trying to digest it. If your seven years are not over yet, you can be relieved to know that this “fact” is a complete nonsense.
Although the origins of this myth are elusive, he confirmed the relative truth about chewing gum. It is indigestible. The Food and Drug Administration defines rubber as a “non-nutritional chewable.” (Translation: this is not food).
Although it is not recommended to swallow your chewing gum, what happens to it is not so exciting. Exceptional ingredients, such as sweeteners, can be digested, but the main part of the chewing gum is an elastomer that moves through the digestive tract without being broken. Then the gum exits from the other end through the excretory system and is usually intact.
Foreign, inedible items should be about more than a quarter of the United States to get stuck in your digestive system. Otherwise, they flow like junk downstream, straight from the other end.
Chocolate will make your skin broken:
As if puberty, middle school and those teenage years are not complicated enough, many of us grow up after learning that our chocolate consumption has a causal link with breakthroughs. It's pretty awful that chocolate, the only thing that makes adolescent tolerant, illuminates your face with ugly zits.
Well, are we here to let you know that these old wives? the tale is false. Eating chocolate will not make you break free. However, eating foods high in fat and sugar can increase your natural production of sebum, which makes your skin more oily. In addition, these unhealthy products lead to higher levels of skin inflammation.
But will there be chocolate or any food in this regard - snatch the skin? The answer to this sounds no. Consumption of high levels of fatty foods will certainly lead to an increase in blood sugar levels, which may indirectly affect breakthrough levels. But not a single food is your golden ticket to avoid teen acne.
Carrot improves eyesight:
The myth that carrots will improve your vision ends in the perverse history of wartime propaganda. In fairness, it should be noted that carrots are an excellent source of beta-carotene, inactive retinol, which is converted to vitamin A during digestion. Vitamin A provides all sorts of benefits for the body, including the protection of vision.
But does it really improve night vision?
No. The British Ministry of Information campaigned during World War II, in which the Royal Air Force pilots ate a lot of carrots, explaining their supernatural ability to shoot down German fighter pilots under the cover of darkness. In truth, all the carrots in the world could not give you the gift of night vision.
British troops defended the German bombers with new technology on the radar radar. It is illegal that German intelligence bought the idea that British pilots were feeding on high-octane carrots.
However, for almost a century, when the public of the Western world remained firm, believing that if they eat enough orange material, their eyes will be grateful to them. We hate to be the ones who break it to you, but in the near future you will not have night vision.
We have five senses:
It should be easy, right? Not so fast. The belief that we have five senses dates back to the time of the Greek philosopher Aristotle, who was the first to recognize the five discrete senses of the human body. You probably recognized them in elementary school: sight, hearing, smell, touch, taste.
Yes, these are your five senses. But they are not the only ones.
Let's start with the basics. What is the "meaning"? Well, this is something with a sensor that can sense a given stimulus. Every feeling is activated by a unique phenomenon.
In fact, the feeling of touch is actually much more complicated than just one feeling. Many neuroscientists break the “touch” of diverging sensations, including the perception of pressure, temperature, and pain.
Depending on what you ask, people have as many as 33 feelings. These include certain feelings, such as blood pressure and balance, that you knew, but were not considered “meaning.” So, the next time someone says that they have a sixth sense, you can answer by saying that you have 33. They may not know what you mean, but you know!
Rolling your tongue is genetic:
Many of us remember how a biology teacher teaches no less that our ability to roll our tongues was a simple genetic fate. Most people can scroll through their tongues, and public wisdom says that language skipping is the dominant genetic trait. If one of your parents could do it, so can you. Or so they told us.
In fact, it is not so simple. Unlike many of these myths of the human body, we have a good idea where this one comes from. In 1940, the American geneticist Alfred Stoutevant published a study in which it was concluded that your ability to roll the tongue is a hereditary trait based on the dominant gene.
However, Sturtevant's abundance over his find was short lived. People quickly realized that there are similar twins, where you can roll the tongue, and the other - no. As a result, the Stotevant's finds were quickly debunked, and the man at the helm lost the defeat.
And yet, after decades in classrooms around the world, this lie is unfolding anew. Now that you know the truth, you can stop the madness from spreading the next time someone opens this fancy hallway.
Heat comes out of my head:
Between the myth that we use only 10 percent of our brain and the prevailing idea that we lose most of our body by heating our heads, it seems that our skulls cannot break. The prevailing hypothesis about the origin of this myth: Scientists conducted research in the 1950s, when objects were exposed to low temperatures and lost a continuous piece of their heat through their leggins.
The problem with this research is that the items were collected in a coat, and only their heads were exposed to the elements. So yes, if every part of your body is isolated and your head is missing, you will lose a disproportionate amount of body heat through your head.
However, more recent studies show that, ceteris paribus, an excessive amount of heat does not escape your head. You lose about 7 percent of your body heat through your head, which makes sense because your head makes up about 7 percent of your body's area.[[[[
So, treat your head like any other part of your body. When he has a cold, pack it and everything will be fine.
Hair and nails continue to grow after death:
This “fact” about the human body seems to be creepy, isn't it? The idea that keratin turtles grow on our lands for several days and weeks after death is whimsical. Well, we are here to let you know that this is simply not true.
Our bodies dehydrate rather quickly, as soon as we die. When this happens, our skin starts to wrinkle and pulls inward. This gives the illusion that our hair and nails are still growing. On the contrary, the rest of the body simply shrinks. For this reason, suicide bombers often put corpses in moisturizer to prevent them from trimming.
Crack joints can cause arthritis. :
Arthritis is not one condition, but rather a universal term for a group of pain syndromes characterized by joint pain, swelling and inflammation. Unfortunately, this is quite common, affecting more than 50 million adults and 300,000 children in the United States. Arthritis can be mild or debilitating. It may flare up or feel like a slow and steady burn.
Obviously, if you can avoid arthritis related actions, you should. For many people who care about their health, this includes a seemingly simple request - do not crack joints. However, we must tell you that hacking your joints does not make a list in your fight to prevent arthritis.
But first, what is “hacking” joints? This sound is associated with blisters, breaks in your synovial fluid (a material that lubricates your joints). As bad as it sounds, a cross-sectional analysis by doctors at Harvard Medical School found no evidence that cracking of the knuckles has a causal relationship with arthritis.
However, you can still give up the habit. Chronic cracking is associated with weaker traction. Besides, it is just annoying to listen.
Break your beard, and it will return Darker:
Who has not heard this? You can shave your beard or women’s hair on your legs, but your efforts will be in vain. Not only will hair grow, we are told, but it will grow faster and darker than before.
This is absolutely wrong. In fact, we know that this is quite a while. One of the first modern studies on this issue took place in 1928. The participating men all shaved in the same way with the same brand of shaving cream. Then their subsequent new hair was analyzed at a higher growth rate.
A lot of this myth comes down to perception. As our hair grows, our biased bias can affect us. Also, when you wax or shave your hair, it’s like chopping wood and leaving a stump. You are left with wider and more visible hair, contributing to tangible benefits from your stubble.
Alas, any changes in growth rate can be caused by hormonal changes. But otherwise it's all in your head!
