Facts about human health. Random Health Facts You Didn't Know

Myth #1: Drink at least 2 liters of water a day.

For the first time this postulate of a healthy lifestyle was promulgated in 1945. Then the US Board of Nutrition advised all prudent Americans to drink 8 glasses of water a day in order to stay in shape and keep their bodies clean and tidy. Since then, many diets include the same recommendation, and there is an opinion among the people that a large amount of liquid helps to lose weight.

Actually. By itself, water will not bring you any harm, but in large quantities, as you know, anything can be harmful. Try to figure out how much liquid you consume per day: even if you exclude all other drinks, you still eat vegetables and fruits and thus get moisture. If overdone, the result can be a condition called hyponatremia, or, more simply, a lack of salts in the body. This will greatly increase the risk of cardiovascular and other serious diseases, says Dr. Rachel Vreeman, an associate at the Center for Child Health Research at Indiana University.

Myth #2: Stress makes your hair turn gray.

Recently, it is fashionable to blame everything on stress - from acne to cancerous tumors. This go-ahead is perhaps the second most popular after “lack of vitamins” and “malnutrition”. By the way, they often explain hair loss.

Actually. Stress really has a negative effect on our body. The more nervous a person is, the faster they age, says Dr. Nancy Snyderman, because stress increases the amount of free radicals in the body. And they, in turn, are the main culprits for the appearance of wrinkles and hair loss. However, there is no scientific evidence that stress is accompanied by graying, no. The timing of the appearance of gray hair is determined by our genes, not by the ability to control ourselves.

Myth #3: Reading in dim light damages your eyesight.

Do you remember what your mother told you as a child? Brush your teeth in the morning, wash your hands before eating, sit up straight and don't read under the covers. And now a good half of the population of our planet is confident in the inviolability of this rule.

Actually. When you read in low light, your eyes have to seriously strain. However, the maximum that this threatens is headache and possibly wrinkles around the eyes. In addition, the eyes may hurt for a while. You will feel itchy and dry, but this will pass fairly quickly. There is no long-term benefit from reading in low light, says Snyderman.

Myth #4. Coffee is bad.

Disputes between tea and coffee lovers have been going on since ancient times and probably will not end for a very long time. We will try to understand a lot of arguments and give only medical facts.

Actually. And again we return to the question of a sense of proportion. Of course, if you do not leave the coffee machine all day long, by the evening you will be a real bundle of nerves, ready to burst at any moment. See above for the effects of stress on the body. But in moderation, coffee can even be beneficial.

First, coffee, like green tea, contains antioxidants (of course, if we are talking about a natural product). And therefore significantly reduces your risk of developing type 2 diabetes, says Idaho Medical Center nutritionist Stacey Beeson. A recent study from Harvard University showed that for women who drink coffee daily, this risk drops by as much as 30%. Other similar studies show that coffee also reduces the risk of bowel cancer, cirrhosis of the liver, Parkinson's disease, and gallstones. Another plus is that coffee stimulates brain activity and, contrary to popular belief, does not increase the chances of undermining the cardiovascular system.

At the same time, the norm for the average person is no more than 3 cups per day (based on 100 ml per cup), Beeson believes. If even this amount brings you insomnia and high blood pressure, cut it in half or switch to substitutes. If you are pregnant or lack calcium in the body, it is better to consult a doctor.

Myth number 5. When high temperature you have to starve

This myth has been going on since those distant times, when there was simply nothing to treat a cold, and people went to any, even the most ridiculous, in our opinion, means to get rid of the disease. Another reason for this belief is that the digestion of food slightly raises the body temperature. People who are fond of self-medication also believe that in the heat you should not take away the body's strength to process food - it supposedly has few of them anyway.

Actually. As a rule, colds and fever are caused by various viruses that enter the body and live in it from a week to 10 days. How you eat during this time does not affect the lifespan of the virus, says Vreeman. Doctors have no scientific evidence that diet during illness somehow affects the body's resistance, but even if you don't really feel like eating, it's better to have a snack with something small but juicy. Because, whatever one may say, you simply need fluid to stay hydrated. In addition, moisture will help you to bear the disease more easily - it will reduce the amount of mucus, thereby alleviating a runny nose and cough.

Myth #6: Fresh food is better than frozen food.

Since scientists learned about such a wonderful thing as antioxidants, nutritionists have been praying in unison for fresh products. “Freezing kills useful substances,” is how doctors repeat the mantra. The same applies to any cooking method associated with heat treatment.

Actually. Frozen fruits and vegetables can be just as good as fresh ones if they are harvested and frozen, as they say, at their peak of ripeness. And cold processing and sealed packaging retain much more vitamins than what remains in “fresh” products that have lain in the sun or in a supermarket refrigerator.

Myth #7: Eggs increase cholesterol levels.

The logic of this statement is simple: the eggs themselves contain a lot of cholesterol - accordingly, if they are, the level of this harmful substance in the blood will increase.

Actually. The latest research in this area has shown that only certain types of dietary fats affect cholesterol levels. And they are much less in eggs than, for example, in medium-fat milk (almost 2 times). At the same time, eggs contain proteins, vitamins A and D. They are inexpensive, accessible and easy to prepare. So one egg a day would be a very healthy addition to your diet, Beeson says.

Myth number 8. If you freeze, you will catch a cold

Another common truth, told to us in childhood. And since my mother said so, then it is so?

Actually. Lowering the external temperature does not affect the state of immunity. Unless, of course, we are talking about extreme degrees of frostbite, when it is no longer necessary to worry about a cold. And we catch a cold, as mentioned above, thanks to viruses, and not because of the cold. With regard to the trend towards the largest number colds occur in the cold season, it is not associated with temperature. The fact is that in winter we are more often indoors, pushing ourselves in the subway, sitting in a cafe instead of walking along the street. And this is the most favorable soil for the spread of infection.

Why is it important to take an interest in health?

It is clear that health is of the utmost importance. Why? There are two key reasons:

• health significantly affects the emotional and spiritual development of the individual. You can get rid of a lot of things that cause harm. You can leave an unsafe job, change your region of residence, etc. However, a person cannot get rid of his body. And if he chooses something that systematically harms him, this will affect not only the body itself, but also the soul. After all, everyone knows very well how difficult it is to be in good mood if you have a headache or a toothache. But more serious health problems can be much more unbalanced;
• It is health that determines the quality of life. A simple example can be given here. Even the most thoroughbred horse will never win at the races if it is not taken care of. The same can be said about the human body. If you do not pay due attention to his health, it is impossible to use all your maximum potential.
