What Really Happens When You Wear A Bra Every Day (2 of 3)
Breathing Room In Your Bras Is Essential
If you have ever let out an audible sigh of relief after taking off your bra at the end of a long day, your body might be talking to you, and very loudly. Tight bras with features like underwire can begin to compress on your chest and armpits, which can possibly interfere with lymphatic drainage and circulation of blood. Your lymph system is a critical component of your immune system, and cannot function properly without the room to flow freely.
Research now speculate that wearing tight bras can potentially hinder the flow of lymphatic fluid, which can possibly have an impact on immune response and detoxification over time. These results are not definitive, but they do indicate that there are potentially negative side effects to wearing a bra that you feel pressure from.

Skin Irritation and Breakouts
One aspect of wearing a bra that many dont talk about is bra acne, or what dermatologists refer to as mechanical acne. The bra you wear all day while sweating and moving with friction can cause bacteria to build up in the compressed areas along the band or the back. The result of this is inflamed skin, pimples, breakouts, and rashes.
Synthetic fabric that many bras are made out of, along with the tight-fitting nature, can make matters worse. If you dont have breathability in your bra, and you wear it multiple days without washing, you are asking for irritation and skin problems.
Choose softer fabrics that have moisture-wicking features, such as bamboo or cotton. Also be sure to regularly rotate out your bras and give your skin a chance to just breathe.
