Video: ❶ The Stupidest Health Myths
The latest medical research provides more and more reliable information about human health. This helps to get rid of widespread myths about health based on false information. The most popular misconceptions include the following false truths. Location: Location:
1. An ordinary person uses only 5-10 percent of the capabilities of his brain
This is one of the most common health misconceptions. In fact, there are no inactive parts in the human brain, just certain parts of the brain are better at coping with certain operations. However, a decrease in brain volume will affect a person's personality in a very destructive way, as proved by experiments with lobotomy, widespread in the first half of the last century.
2. Every day you need to drink at least two liters of water
Water is vital for the body, but there is no exact norm to be followed. In matters of the volume of fluid consumed, it is more correct to focus on your own well-being. For example, it will not be superfluous to increase your water intake after exercise or just in the heat. By the way, the body's fluid reserves are replenished both from pure water and from the soups, juices, milk and tea consumed in food.
3. The best treatment for a cold is nasal drops.
In fact, drops of a runny nose do not cure at all, but only temporarily facilitate breathing with severe nasal congestion. Therefore, they should be used in this capacity, and even then no longer than a week. Longer use of the drops will harm your health, as the nose will become addicted to them and will no longer be free of mucus on its own. Over time, drops will have to be applied more and more often until the nose stops responding to them at all.
4. Reading in low light reduces vision
The only health impact of reading in semi-darkness is to increase eye fatigue. But from the fact that the eyes get tired, vision will not deteriorate. This is true both for watching TV and for working at a computer. In the worst case, the eyes will turn red and a feeling of "sand" will appear.
5. You can not wake a person suffering from somnambulism
If someone wakes the sleepwalker, nothing bad will happen to him. However, the danger exists for the person who woke him up. Because sleepwalkers in the first minutes after a sharp awakening can behave aggressively.
