Is it normal to sleep with wet hair?
Yep.Totally normal
Yes, it’s normal to go to bed with wet hair, and it won’t make you catch a cold. Wet hair is more fragile, though, so rough tossing and turning can cause extra tangles or breakage.
Plenty of people shower at night and don’t bother drying their hair all the way. Sleeping with it wet isn’t inherently harmful, and it won’t give you a cold.
The main downside is that wet hair is easier to tangle or break from friction against your pillow. If that’s an issue, gently squeeze out extra water, use a soft towel or pillowcase, or loosely braid longer hair before bed.
