This is one of those debates that will go on and on till eternity. Even though most of the ladies are not wearing a bra when going to bed to avoid marks, the “constricted” feeling and even the fear of clogging the lymphatic glands leading to breast cancer, there are also the religious nighttime – bra – wearers (like Marilyn Monroe) who believe strongly that it prevents their breasts from becoming saggy. From a scientific perspective both of these theories are myths at best.
The function of the lymph nodes in the underarms is to act as natural filters that drain the breast of lymph fluid, and as body’s first defense against cancer cells, foreign material and infections. It hasn’t been scientifically proven that wearing a bra obstructs the pathways of the lymph nodes. So scratch the breast cancer from your list of fears
The most common causes of breast sagging are breastfeeding and pregnancy, and age and genetics are the ones that determine the extent of sagging. If the size of your breasts is above C then choose a soft – cup style, without much fasteners or hardware, which will provide some support from sagging. For all others sizes, the bra is not preventing sagging in any way. To summarize, sleeping in a bra or without a bra at night is really just a matter of the woman’s personal comfort. For some women who suffer from rashes below their breasts from the moist skin – to – skin friction, wearing a bra can be painful, and for other that have tender breasts, they need the bra support. If you do wear a bra at night, first thing is to avoid an ill fitting and choose a soft cupped, natural fiber (all – cotton wireless) bra, that will help you keep all that moisture away from your skin.
