there's two schools of thoughts. one being it helps support the breasts during sleep keeping them lifted from the effects of aging.( a comfort thing as well ) the second being, its not good for drainage of the lymph nodes.

I wouldn't ever wear a bra to bed if I were you. Just like someone else said, the glands in the breasts get blocked up and there is little movement. This can, over long long periods of time, lead to cancers. When your body cannot drain itself and get the juices flowing, toxins build up and can form tumors and such.
Plus, all that sweating will lead to breast acne. Gross.
