No, most girls do not sleep with a bra on. While some women choose to wear a bra to bed, often due to comfort preferences related to breast size or pregnancy, the majority do not.
Prevalence of Sleeping in a Bra
Studies and online discussions show that wearing a bra to sleep is not the norm. One source explicitly states that only 40% of women wear sleep bras. [^1, ^2] This suggests a significant portion of women prefer to sleep without a bra.
Reasons for Sleeping With a Bra
- Comfort: Some women, particularly those with larger breasts, find that wearing a supportive, non-underwire bra provides more comfort during sleep. ^3 Pregnancy can also increase breast size and sensitivity, leading some women to prefer wearing a bra at night. ^3
- Personal Preference: Some women simply prefer the feeling of wearing a bra, regardless of breast size. One Reddit user reported wearing a bra 24/7, with occasional exceptions. ^4
Reasons for Sleeping Without a Bra
- Improved Circulation: Wearing a bra, especially one with underwire, can restrict blood flow. Sleeping without a bra allows for better circulation. [^1, ^5]
- Comfort and Freedom: Many women find sleeping without a bra more comfortable and liberating. [^6, ^7]
