I'm gonna have to say without. The material irritates my skin when I sleep with a regular bra on, but I don't think it gives you chances of cancer lol. Ive been sleeping with bras on for like 3 years & ihave no problems(i forget to take them off allll the time.). But sports bras are probably fine.
Lol I prefer without one but when I go to sleep I'm just too tired and I can't ever remember to take them off.. So I usually sleep with one xD but I take them off if I remember:P
I wear a c cup and I sleep without one. I toss around in my sleep so my bra just gets super uncomfortable and irritating, and puts a lot of strain on my back.
I can't sleep with a bra on, it's very uncomfortable. I don't like wearing them when it's hot either, havn't worn one in a couple of days :)
It really is personal choice, larger breasted women might find the support more comfortable though. Personaly I sleep without one.
no, there has been no evidence found to support the bra, underwire or not is a cause. http://funadvice.com/r/bt9ku1l2tgn
Its all personal preference. I personally hate bras and it comes off as soon as I get home basically :p
I think its better to sleep without one on. There isnt so much pressure on your breasts from the bra.
There's no medical or scientific proof to actually back that up, it's a proven myth if anything.
If you do sleep with a bra on you have a better chance of getting breast cancer.
That's only if it has an underwire isn't it? o-o
I LIKE TO SLEEP WITHOUT ONE! Yeeaaahh buddy.
I like to sleep with a sports bra.
Without a bra.
