A number of stereotypes regarding human health can be singled out, which turned out to be in fact only delusions. This article presents the most common myths about human health.
10. It is better to eat several times a day, but little by little - a myth!
Experts have proved that if you eat often, but in small portions during the day, this will not affect weight changes, body fat and metabolic rate. Many people still believe that it is better to eat that way, but there is no reliable scientific justification for the benefits of this method of eating food. The main thing is to control the number of calories, give preference to healthy food and take into account the principles of proper nutrition. So you can effectively control your weight and maintain your body in good condition for a long time.
9. Each person’s fingerprints are unique - a myth!
Every person from childhood is confident that his fingerprints are unique, but this statement is doubtful. British forensic expert Mike Silverman notes that it is impossible to prove the uniqueness of fingerprints at this time. Just over 10 years ago, fingerprints were repeatedly identified erroneously, as a result of which many innocent people were punished. The expert said that papillary patterns on the fingers of relatives can be almost identical, but it’s impossible to say that each print is unique.
8. Antiperspirant should be used in the morning - a myth!
Almost all people use antiperspirants after waking up, before work or school. This seems to be quite logical. However, Nikita Wilson, a cosmetic chemist, argues that such products are best used in the evening, after water procedures. The skin on which the antiperspirant is applied should be dry and clean. As part of such funds there are active elements that clog the sweat ducts during a person’s sleep. So the action of antiperspirant is significantly extended.
7. Nerve cells cannot recover - a myth!
Scientists have been very confident for a long time that each person is born with a certain number of nerve cells (neurons), and over time they become less and less, since they are consumed throughout life. However, nerve cells are produced continuously by the brain: the name of this process is neurogenesis. At the beginning of the XXI century, scientists proved that even 70-year-old people have new neurons: this happens in some areas of the brain.
6. If there are no problems with vision, there is no need to go to the ophthalmologist - a myth!
Usually people who have good eyesight do not visit an ophthalmologist because they think that they do not need it. However, it should be borne in mind that some eye diseases can develop asymptomatically: for example, glaucoma. So says ophthalmologist Ann Sumers. Even one of the main symptoms of glaucoma is often overlooked: loss of peripheral vision. To avoid such problems, you should visit an ophthalmologist every year. An experienced specialist can easily determine a disease in the early stages.
5. People have become smarter - a myth!
Gerald Crabtree, a specialist in the field of genetics, is convinced that the people who live now are more emotionally unstable and stupid than their ancient ancestors. Medical and technological achievements of people in this regard do not save. The intelligence of our ancestors began to deteriorate when hunting and gathering ceased to be their main means of survival. At present, the struggle for life has ceased to be fierce, since now people are facing significantly less dangers, and all that is needed can be purchased in stores (and without even leaving home).
4. If you wear a bra all the time, the risk of developing cancer increases significantly - a myth!
A few years ago, scientists found that a bra can not affect the development of cancer. It is absolutely safe even if you wear it not from time to time, but daily. At the end of the 20th century, the book “Dressed for Murder” was published: it was she who caused fears regarding the influence of the bra on the development of such a terrible pathology. Moreover, it was written not by medical researchers, but by anthropologists.
3. The appendix is useless - a myth!
Scientists have long been convinced that the appendix is an organ that is completely useless, that human health does not depend on it. However, later it turned out that it is a kind of reservoir, which contains bacteria that are beneficial to humans. If necessary, they help fight infections and help improve digestion.
2. People suddenly turn gray from sudden intense stress - a myth!
According to legend, Marie Antoinette, Queen of France, before her execution became gray-haired due to strong unrest. For a long time it was believed that people turn gray, experiencing great stress, and almost in a few moments, but this is not so. This myth has not yet been proven by any study. However, experts note that healthy pigmented hairs gradually fall out if a person is constantly in chronic stress. This can take several months or even years.
1. The heart stops briefly when a person sneezes - a myth!
All people know that the sensations that arise during sneezing are not very pleasant: it seems that the heart jumps out from the inside. The man exhales sharply, his eyes shut. Many people believe that temporary heart failure occurs during sneezing. However, David Ratlen, an American cardiologist, claims that while sneezing, intrathoracic pressure increases. Blood flows worse to the heart, so it starts pounding differently, but this organ still remains active, does not stop its work.
