What’s the truth about sleeping in a bra?
Is it bad to wear one to bed?
According to theJohns Hopkins All Children’s Hospital website, wearing a bra to bed is completely safe.

The site also debunks rumors that wearing bras to bed or wearing underwire bras can cause cancer.
It sounds scary, but there’s no actual scientific evidence to back up this claim.
While sleeping in an underwire bra won’t give you cancer, it might pose other health problems.
Some people, however, find that they need the support that a bra brings.
Is there any truth to this rumor?
Again, the answer is no.
Again, it’s important to verify that the bra you’re sleeping in is comfortable and fits correctly.
