No, but it's good for the breast tissue to be without sometime.
No.
There is no scientific evidence to support the claim that wearing a bra to sleep can stop the growth of the breast. Breast growth is primarily determined by genetics, hormones, and age. It is generally recommended to wear a comfortable bra that provides support during the day, but it is not necessary to wear one while sleeping.
No it does not. It's not good for them to sleep with a bra on though.
No, not at all.
It will not affect breast development but it might be uncomfortable.
Yes. There is no medical reason not to do so. If your bra is too tight or the under wire is poking out then you shouldn't be wearing it in general, especially while sleeping. If it is a padded bra, sleeping in it may compress the padding and leave it wrinkled and misshapen.
Depends. Some people have said if you are sleeping with a bra on, you could get breast cancer and less worse, breast pain. The Genie Bra has no hooks, compared to others. There is a higher chance of getting breast cancer. So I say there is no chance of getting cancer, but maybe pain. That's it.
Not necessarily. There is no reason to think that sleeping with a bra on will lead to harm to your health. However, as with wearing any restrictive clothing, awake or asleep, your growth may change slightly as you sleep. Some people believe that wearing bras whilst sleeping minimises the size of your breasts. Some people simply find it more comfortable. In the end, it is simply your choice.
yes bra helps shaping your breast
No, and I don't know what you mean with too often since most girls and women wear them all day long.
Getting breast cancer has nothing to with wearing a bra.
