Contrary to popular belief, our bodily functions and other functions are not the work of little intestinal goblins doing black magic deep within our insides. All anatomical riddles have an excellent scientific explanation, which remains a secret only for those who have not received a medical education. And here are some examples.

Painful aches during a cold are not caused by a virus, but by the activity of the body

White blood cells are part of the immune system, but they can also cause problems. They produce chemicals that are carried through the body and tell the immune system where the lesion is. This process causes painful sensations.

The eyes in the pool do not turn red from bleach, but from dirt

Bleach is unfairly accused of reddening your eyes after swimming in the pool. The problem is actually caused by bodily fluids such as urine and sweat. Urine enters with chlorine into compounds responsible for skin irritation and this specific pool smell. Think about it the next time you want to bathe in the baby pool without a diaper.

You feel "butterflies in the stomach" as a result of the outflow of blood

Sometimes our ancient brain feels anxiety, but cannot determine the reason - whether it is a date with a girl, or a hungry jaguar. Then he disrupts the hit-or-flight stop-tap, which causes an adrenaline rush and pumps blood from the stomach to the extremities (which becomes the cause of the "butterflies"). It also weakens the sphincter, helping to relieve bowel movements.

Peeing in the cold is a way to survive

Cold diuresis happens when your nervous system tries to ward off hypothermia by constricting capillaries in your limbs and redirecting blood to more important organs. The excess blood now circulating in the abdominal cavity instructs the kidneys to free up space and get rid of excess moisture.

You feel nauseous in the car because your body and brain cannot agree

During the ride, your eyes see movement, and your brain assumes that you are just sitting. And then a part of the brain called the thalamus decides that you have been poisoned, and presses the button to clear the system. If you are driving, your brain has more information - which is why drivers are not sick.

Does coffee disrupt the well-coordinated work of the body? Hormones are to blame

If you get up at 6:30 in the morning to go to work, then the best time for a cup of coffee will come somewhere between 9:30 and 11:30. Otherwise, cortisol levels can jump, causing anxiety or insomnia.

So there's a scientific reason for the coffee break.

Paper cuts are so painful because they are lacerations

Paper cuts hurt more than other injuries because the tips of the fingers are lined with nerve endings. And paper, even with the smoothest edges, at a microscopic level, bristles with jagged edges like a saw. Instead of a smooth cut, it leaves an untidy laceration that cannot heal in any way.

We cough in the theater because we are social creatures

On average, a person coughs about 16 times a day, but twice as often in the theater. In moments of calm, coughing rolls around the hall in a wave, because people unconsciously copy each other.

Chips trick your brain and you keep eating without getting full

Every next bite of the same taste we swallow seems less attractive to us - this is how the brain fights overeating. But chips have a complex bouquet of flavors, in which it is difficult to single out one thing. Plus, each chip melts in your mouth so quickly that your brain thinks it can't have a lot of calories.

It is difficult for obese people to adhere to a diet due to taste buds

Gaining excess weight leads to a violation of taste, and recently it was found out why this happens. In obese people, inflammation of the taste buds is often observed. Desensitization begins, which makes it difficult for fat people to be faithful to salads and lean meats.

This means that we still have not figured out how to make healthy food taste good.
