Why shouldn't you go to bed with wet hair?

Because of working all day, then continuing to attend meetings, go to school or take care of the family, many people often shower and wash their hair quite late. Sometimes, the hair cannot dry in time for bed. If you dry your hair with a hair dryer, it will damage your hair in the long run, while letting your hair dry naturally takes a long time, according to the health website Healthline (USA).

Sleeping with wet hair makes hair prone to breakage

Sleeping with wet hair can lead to the following health risks:

prone to runny nose

Some people think that sleeping with wet hair will easily cause a cold. However, scientifically this is not true. Because colds are caused by viral infections, usually Rhinovirus.

We can only catch a cold by coming into contact with the virus on surfaces, droplets, or shaking hands with an infected person. However, going to bed with wet hair can cause a runny nose and nasal congestion.

Fungal infection

Going to bed with wet hair will keep your hair and scalp moist for a long time. This is the perfect condition for fungus to grow. Fungi like Malassezia will cause conditions like dandruff or dermatitis.

Not only the scalp but also wet hair makes the pillow damp. In particular, if the pillowcase is damp, it will be an extremely favorable environment for mold to grow. If mold grows a lot, it can irritate the trachea and lead to some respiratory problems.

Hair breakage

Wet hair is prone to damage if not properly cared for. Going to bed with wet hair can cause breakage when we turn over or lie on it.

To prevent these harmful effects, people should wash their hair early so that it can dry. If it is close to bedtime, you can use a hair dryer. However, you should not dry it at too hot a temperature or too often because it will cause the hair to lose its natural oil layer. As a result, the hair will lose moisture, become dry and prone to frizz and breakage.

In addition, to avoid hair damage, everyone should use conditioner after shampooing. Conditioner will create a thin layer covering the outer cuticle of the hair, thereby helping to reduce friction and make it easier to detangle when tangled. In particular, people who have dyed their hair or used chemicals on their hair should use hair conditioner after each shampoo, according to Healthline .
