10 common myths about our body that are not reality.
1. If you touch a toad, you will get warts:
Warts in humans are caused by a virus known as human papillomavirus. It cannot be picked up from animals with warts, and certainly not from toads, whose pimples are not warts, but glands.
2. Can't wake sleepwalker:
With sleepwalking, a person begins to walk and perform various actions while in a dream. Waking a sleepwalker may make him feel confused and disoriented, but it's still better than the injuries he can get from tripping over objects and walking in dangerous places. Therefore, you should gently wake him up and help him return to bed.
3. You can catch a cold if you go outside in wet, cold weather:
There is no evidence to support this belief. Viruses are more common during times of lower humidity in winter. In addition, during the cold season, people spend more time indoors, where these viruses can easily spread. The only thing that is known is that the cold reduces our resistance to the infection that we have already contracted.
4. Hair and nails grow after death:
Neither one nor the other continues to grow. It's just that after death, the cuticles and skin wrinkle, which makes it seem as if the nails and hair have lengthened.
5. After shaving, the hair grows thicker and darker:
Unshaved hair is tapered and therefore does not look as thick as after shaving. In addition, uncut hair is more exposed to the sun, which lightens it a little. Therefore, cut hair appears to us darker at first.
6. Men think about sex every seven seconds:
If this were true, it would be quite difficult for men to concentrate on certain necessary things, such as work. Although there is no way to verify this, scientists say that such a claim is a gross exaggeration.
7. Different areas of the tongue are responsible for different tastes:
The idea that taste buds on different areas of the tongue correspond to sweet, sour, pungent and salty tastes has been ingrained in the minds of most people for a long time. However, this is not the case. Every area of the tongue can taste every taste. The very myth that there is a map of the tastes of a language originated from a German newspaper mistranslation of a theory proposed by a professor at Harvard University.
8. We only use 10 percent of our brain:
William James, a psychologist who lived in the 1800s, once metaphorically expressed the idea that we only use 10 percent of our brains. This phrase grew into a rumor that the rest of the brain is incomprehensible and not used. In fact, inactive neurons are just as important at any given time as active ones, and 10 percent come from different areas of the brain.
9. If you squint your eyes, they will remain so:
When you look at your nose, it creates normal convergence, that is, the number of rotations of the eyes in relation to each other in order to see the object being captured. With strabismus, one eye looks straight and the other looks to the side. Most often, this disorder occurs in children, and it is caused by diseases of the nervous system, trauma and other diseases. In adults, it occurs in extreme situations, such as stroke, Graves' disease.
10. Reading in the dark impairs vision:
Reading with a flashlight in the dark will not affect your vision, but it will make it difficult for you to read. The eyes contain two types of receptors: rods and cones. Cones allow us to read and see colors, while rods capture movement in our peripheral vision and allow us to see in dim light. It will not do any harm, except for more eye strain.
