Many people have gone to bed with wet hair after a late-night shower, especially when time is limited. While it’s a common habit, you may have heard claims that sleeping with wet hair can cause serious health problems. In reality, most of these claims are exaggerated, but there are a few practical reasons why this habit may not be ideal.
Although sleeping with wet hair won’t cause a cold or severe illness, it can contribute to hair damage, scalp irritation, and reduced sleep comfort in some individuals.
Does Sleeping With Wet Hair Make You Sick?
One of the biggest myths is that sleeping with wet hair causes colds or the flu.
Colds and influenza are caused by viruses—not by having wet hair. While being cold or uncomfortable may affect how you feel, simply sleeping with damp hair does not create a viral infection.
Maintaining good hygiene and avoiding exposure to contagious illnesses are the most effective ways to reduce your risk of getting sick.
Increased Hair Breakage
Hair is generally more fragile when it is wet.
Tossing and turning during sleep creates friction between your hair and the pillowcase, which may increase the likelihood of:
- Split ends
- Hair breakage
- Tangles
- Frizz
People with long, fine, or chemically treated hair may notice these effects more easily.
