There are deeply rooted beliefs about the human body that are passed down from generation to generation. Since childhood, we listen to the advice of our grandmothers and mothers, teachers, and even doctors, which we are sure are good for us, but they are not scientifically based. These are the myths we believe:
Hair grows thicker after shaving
It is a widely held belief that shaving hair causes it to grow back thicker and firmer. This is not true because shaving only removes dead hair on the surface of the skin and does not affect the type of growth.
Reading in half-darkness impairs vision
When you read in a dimly lit room, your eyes strain a little more than usual, but there is no scientific evidence that you will harm your vision in the long run. Semi-darkness will cause faster eye fatigue and dryness, but without consequences, unless you read constantly in the dark.
It is dangerous to wake a sleepwalker
It is believed that it is dangerous to wake a sleepwalking person, but actually it is a worse option to leave him alone because he can get hurt. It's best to walk him back to bed so he won't feel disoriented and confused.
We need eight hours of sleep
Although experts claim that we need at least eight hours of sleep every night to be able to function normally during the day, this does not apply to everyone. For some people, less sleep is enough.
We must drink eight glasses of water
The advice was about liquid, not just water. The human body needs a lot of liquid, but also through the intake of food and other drinks, not just water.
Superfit means super healthy
Playing sports is healthy, but overdoing it causes health problems. Professional athletes are at high risk for various injuries, but they are not the only ones at risk. If you exercise daily for more than two hours, there is a greater possibility of chronic fatigue, insomnia, depression, problems with the menstrual cycle and reduced sexual desire.
We gain weight because of a slow metabolism
A faster metabolism is thought to cause more calories to be burned. But obesity is not only caused by slow metabolism, but also by other factors such as unhealthy diet, lack of exercise and more.
Wet hair in winter invites a cold
Although cold is believed to cause colds, there is no connection between the two. In winter, people are more likely to get infected indoors because they spread viruses to each other.
Experts even claim that cold weather helps boost immunity for the future.
A high protective factor protects against skin cancer
Sunscreens protect the skin from burns and premature aging, but they are not sufficient and complete protection against skin cancer. When spending time in the sun, be sure to use products that contain protection against UVB and UVA rays, and during the strongest sun (from 11 a.m. to 16 p.m.) stay in the shade.
