7 Diseases That Are Caused By Sleeping With Wet Hair

Many of us are used to go to bed with wet hair. However, this is a big mistake. In fact, sleeping with damp or wet hair can be the culprit of many ailments. This doesn’t mean that we will catch a cold or pneumonia, but trigger other health issues.

When we go to bed with damp or wet hair, the moisture is retained and it can inflame the scalp, causing an annoying itching sensation. Moreover, this can also cause damage to the mane. What’s more, you shouldn’t keep the towel on your head for too long as it has the same effect of retaining moisture.



When the hair is wet, it is more prone to breakage. So, sleeping with wet hair only increases the risk of hair breakage.


Sleeping with wet hair will cause sticky hair. Hence, the hair can be difficult to be entangled. This is especially the case for people with long hair.


As we mentioned before, the wet hair retains the moisture throughout the night. On the other hand, when we sleep, the temperature of the body rises. Thus, there will be a big temperature difference and this will cause headaches.


Sleeping with wet hair can trigger different types of itching. This will happen due to the moisture that is formed in the skin of your head.


Moreover, sleeping with wet hair will wet the pillow and towel, which becomes the perfect breeding place for bacteria. Therefore, it may lead to infections.


Due to the temperature change, sleeping with wet hair may cause muscle pain, severe cramps, and facial paralysis. In some rare cases, it may even lead to paralysis of the whole body and cause death.


When your scalp remains moist for a longer time period, it will interfere with the function of sebaceous glands on the scalp. As a result, these glands will either start to produce more oil or reduce oil production. Moreover, this may disrupt the natural pH balance of the scalp and trigger dandruff or excessive oily scalp.

Therefore, you should avoid sleeping with damp or wet hair and wash your hair during day hours.

If you must sleep with wet hair

If drying your hair fully before bed is just not an option, here are some things you can do to make going to sleep with wet hair as safe as possible:

Apply coconut oil to your hair

There is evidence that coconut oil protects wet hair from breakage.

The hair cuticle is made up of flaps similar to shingles on a roof. When wet, your hair soaks up water and swells, causing these flaps to stand up, making hair vulnerable to damage.

The oil reduces the amount of water absorbed so it’s less prone to damage. This isn’t recommended if you have seborrheic eczema, however, since coconut oil could make it worse.

Use conditioner

Conditioner helps seal the hair cuticle, reduce friction, and make hair easier to detangle.

Bleached or chemically-treated hair can benefit even more from regular conditioning.

Dry and detangle hair as much as possible

If you can get in a quick blow dry or are able to shower a few minutes earlier for some extra air-drying time, do it.

The less water you have in your hair, the better to minimize damage. Be sure to (gently) detangle your hair before going to sleep to help avoid any extra stress on your hair.

Use a silk pillow

There’s some evidence that sleeping on a silk pillowcase is better for the skin because it’s less drying and provides a frictionless surface.

Though there isn’t any evidence of its benefits for hair, the milder surface may also help lessen damage if you go to sleep with your hair wet — or dry, for that matter.
