Sleeping with breast implants is going to be at least a little bit different. If you sleep on your back, there may not be that big a change to your comfort level as you sleep. Side sleepers and stomach sleepers may need to seriously alter their sleep habits. There is also the concern about sagging, which is a common issue when a woman has larger breasts. In addition to issues with sleep position, there is an old wives’ tale that wearing a bra to bed can contribute to sagging breasts in the long run. If you have implants and want your breasts to look their best, you can understand why these are important concerns that can impact long-term results.
