Sleeping without a bra is generally better for circulation, as it allows for freer circulation throughout the breast tissue and surrounding areas, which may help reduce swelling, discomfort, and promote overall breast health. Wearing a bra to bed is not necessary and can potentially restrict blood flow and lymphatic drainage in the chest area. Removing your bra at night allows for optimal blood and lymph flow, which helps remove waste products and deliver nutrients to breast tissue. Although the provided studies do not directly address the effect of sleeping with or without a bra on circulation, the principles of lymphatic drainage and blood flow can be applied to this scenario 1, 2. The study on manual lymphatic drainage for breast cancer-related lymphedema suggests that improving lymphatic drainage can have a positive effect on reducing swelling and discomfort 1. Similarly, the study on the mechanics of lymphatic pumping and lymphatic function highlights the importance of optimal lymphatic flow for maintaining tissue health 2. Therefore, it is recommended to remove your bra before going to bed each night to allow for improved circulation and lymphatic drainage. If you're concerned about support while sleeping, consider wearing a loose-fitting, soft cotton sleep bra or camisole instead of a regular bra, as they provide minimal compression while still allowing for improved circulation compared to structured bras.
