7 Consequences of going to bed with wet hair

Going to sleep with wet hair is a very common routine. Whether it is for not making the extra effort of using the blower and wanting to go to rest after a well deserved shower, or because we are headed to the hair salon the very next day. However, very few people are aware that this practice is not as good as it seemed. Having wet hair when going to sleep is actually very dangerous for our health.

Negative effects of sleeping with wet hair

Here we are listing some of the damages this practices causes to your hair and body.


Wet hair is a constant source of humidity during our time in bed. When we sleep, our body temperature rises, especially during REM sleep. If you combine your warm body with cold temperature of your head cause by the humidity of the wet hear, you will get a shock and the difference can cause you having severe headaches.

Hair breakage

If you ever wonder why there is so much hair on your pillow when you wake up in the morning, sleeping without drying your hair is your reason. When wet, your hair breaks easier than normally. Therefore, if you desire you keep your strands in one piece, dry them out.

Sticky buns of hair

Going to sleep with braids or a bun of wet hair causes your strands to be in a rebellious form, untidy and scrambled, not to mention with unnecessary build up. Performing these so-called tricks will certainly cause more damages to your hair. The few efforts or time you might save at night by not drying your hair will be require tenfold the next day, to unscramble the hairy mess of wet hair.


Pillowcases are perfect magnets for undesired bacteria and fungus to grow on itself. When you couple this culture with the dampness and raised temperature of your head with wet hair, you are creating a perfect storm of bacteria and fungi that will last through many nights. This results in acquiring infections to the scalp (such as the ringworm) that will generate bald spots.

Itchy scalp

Beyond getting infections on our scalp and possible diseases, wet hair is the perfect environment to cultivate fungus on your hair and on your pillow case. The result of this combination is the irritation of your scalp and therefore, an itchy head. It might not lead to severe disease, but it will certainly give you a bad image being seen scratching your head in public.

Source of Dandruff

This dreaded affection is almost a certainty if you sleep with your hair wet. Considering that the practicing we are trying to warn against causes fungal infections and itchiness, dandruff is another consequence of this environment of fungus creation. If you do not want to have flaky dead skin cells wreaking havoc on your looks and scalp health, it is best to dry up the hair.

Bad Sleep

Finally, one of the reasons why you neglected to blow your hair dry before bed might be the exact opposite consequence in this case: not having a good night sleep. The difference in temperatures between hair and body, the hair dripping cold on our face, and the itchy sensation in our scalp are enough disturbances to keep from actually getting that desired good night sleep that made you go to sleep without taking the time to dry your hair even with a towel.
