## Why are hot flashes worse at night?

### Why they can feel worse at night

Hot flashes can be worse at night because hormone levels rise and fall over the course of the day, and many women feel the strongest effects of those shifts after dark. During perimenopause and menopause, changing estrogen levels can make the hypothalamus, the part of the brain that helps regulate body temperature, overreact to small temperature changes. When that happens at night, it shows up as night sweats.

A few other things can pile on. A warm bedroom, heavy pajamas or bedding, alcohol, caffeine, spicy food, hot baths, and exercise too close to bedtime can all make nighttime hot flashes hit harder. Poor sleep can also feed into the problem, since sleep disruption and hot flashes tend to aggravate each other.

At Alloy, we usually suggest keeping the room cool, around 65°F if that’s comfortable for you, using a fan, and wearing light sleep clothes. If hot flashes are really bothering you, treatment can help.
