Sleep Bra – Should You Sleep in a Bra?

Short answer: There is no health reason to sleep in a bra, so it comes down to comfort. If light support feels best at night, choose a soft sleep bra without underwire that does not squeeze or leave marks on your skin.

Is it harmful to sleep in a bra?

There is no good evidence that sleeping in a bra is harmful, and none that it prevents sagging breasts either. What matters is that the bra does not squeeze, pinch or disturb your sleep. A tight underwired bra is therefore a poor choice at night.

How a sleep bra should fit

A good sleep bra is soft, stretchy and free of underwire, hooks and hard seams. A bamboo bra without underwire is an obvious choice, because bamboo viscose is breathable and wicks moisture away, so you do not lie there hot and clammy. Many women wear the same soft model day and night.

Make the night comfortable all the way round

Pair the sleep bra with soft bamboo nightwear for women, so everything you wear at night works towards a good night of sleep. You can read more about how bamboo affects your sleep in our guide to sleeping better with bamboo.
