The head is the most important part of the human body because the brain is located inside it. To protect it from heat, cold and shock, nature gave us hair. When it’s hot outside, hair plays the role of a “built-in hat,” and during frosts it helps to retain heat, at least a little. Also, luxurious hair can soften the blows, which is also vitally important. As you can understand, hair plays a very important role, so it must be protected. Unfortunately, many people lose them due to stress, genetic predisposition and many other factors. It is also believed that hair can be seriously damaged if you wash it and go to bed with wet hair. Is this true?

You can catch a cold with a wet head

Wet hair can give you a headache
There is also an opinion that if a person goes to bed without drying his hair, he will wake up with a sore head. Where this rumor came from is not clear, nor is the reason why people believe it. Perhaps the authors of this assumption believed that while sleeping with a wet head, a person would unconsciously try to escape the cold humidity and strain his neck muscles. But there is no evidence that this is true.

If someone has experienced a headache after sleeping with a wet head, there could be other reasons for this. Perhaps the person had an uncomfortable bed or pillow. It could also be that he was under a lot of stress or drank alcohol.
Sleeping with wet hair can damage your hair
With a wet head, a person is unlikely to catch a cold, and a headache can bypass him. However, hair can actually become damaged while you sleep. In 2015, scientists conducted a study and found that stretching hair 30-70 percent of its original length can cause damage. Wet hair is already prone to breakage because water weakens the protein structure of the hair, making it more elastic. Therefore, friction against a pillow during sleep is a particularly serious test for them.
