Is it safe to wear a bra bed?

The answer is: maybe

Sleep bras or bralettes are typically designed for comfort, provide light support and coverage, and do not have underwires that could cause discomfort. In general, wearing a bra to bed is considered a personal preference and there is no scientific evidence to suggest significant health risks associated with it. However, for some individuals, it may cause discomfort, skin irritation, or affect sleep quality, especially if it provides too much compression or impairs blood circulation. Some women find it more comfortable to wear a loose, non-restrictive bra or sports bra for support while sleeping. Ultimately, the choice to wear a bra in bed is a personal decision based on individual comfort and preferences. If any discomfort or negative impact on sleep is experienced, it is advisable to consider going braless or choosing a more suitable sleep bra.
