Is it Bad to Sleep with a Sports Bra On? (Find Out Now!)

Last Updated on September 9, 2022 by

Not really! Most experts recommend sleeping in a sports bra to give the proper breast support by keeping them separated and reducing their movement and bounce. However, you must choose the bra carefully to ensure it provides the necessary support and optimal comfort. Also, ensure that your sports bra doesn’t pinch or chafe your skin. Otherwise, choosing to sleep with a sports bra depends on personal preferences.

Bras can be restricting and uncomfortable, so it’s no surprise that many ladies like to go braless. However, if you need the support of a bra but don’t like some of the uncomfortable aspects of regular bras, going with a sports bra might work well for you. Sports bras tend to fit more snugly than typical bras, making them somewhat restrictive until you get used to wearing them.

Sports bra types include running, high-impact, and full-figure sports bras. It depends on your specific needs to find the right one for you – if you prefer being more comfortable while you sleep at night, this could be an alternative solution that may work best!

Women worldwide have known for generations what any woman who has worn a bra can confirm. Well-endowed individuals often feel more secure, comfortable, and in tune with their bodies when they wear a supportive brassiere to bed. Therefore, it is no surprise that some of the most attractive bras combine comfort, appeal, and support.

It may be challenging to narrow down one’s choices when so many beautiful styles are available online these days! But suppose you’re an individual who needs maximum support from your brasserie, our recommendation is to go with a sports bra or compression bra instead of a traditional underwire model.

Wearing a Sports Bra to Bed and Breast Sagging

Can Wearing a Sports Bra to Bed Affect Sagging

Women who wear bras for prolonged periods may experience uncomfortable side effects such as skin irritation and pain. This is partly due to the synthetic materials used in the construction and design of many modern-day undergarments. Studies have yet to determine whether sleeping in a bra can prevent breast sagging, as this is thought to be primarily caused by age and weight loss or gain.

Some argue that wearing a bra to bed can provide a modest amount of relief from stretch marks during pregnancy. However, others contend that quality support isn’t vital while resting. It’s also clear that there are no links between bras and cancer.

Wearing a Sports Bra to Bed and Breast Growth 

Various past experiments have been conducted to determine whether or not bras help increase breast size, supportability and even delay breast growth altogether. Studies after studies proved inconclusive over decades, failing to establish whether these claims were true or false. One valid theory is that a bra only supports the weight of a woman’s breast in an otherwise unsupported state. 

Indeed, wearing an adequately supportive garment would have positive psychological benefits, especially for post-mastectomy patients who often experience weakness in the pectoral muscles and psychological stress due to their scars. A properly fitting bra can also help protect against various strains such as costochondritis which can develop into a degenerative disease causing pain in your heart muscle.

When to Avoid Wearing a Sports Bra to Bed

When is it Bad to Wear a Sports Bra to Bed

Having a bra that you can depend on and get comfortable in is essential. If it is too tight or binding, making you feel uncomfortable while wearing, it isn’t working for you anymore. Do not sleep in the following bras; 

  • A bra that pinches the skin
  • Bras that cause rashes in the mornings
  • Wrong size
  • High-impact sports bra
  • A bra that is a too snug fit

As a young woman, always ensure that you wear the right sports bra style to bed. Wearing the wrong bras can result in pain and discomfort, not to mention wiry poking underwires! Be aware of what materials are generally commonly used in products of this kind to protect your health better.

Frequently Asked Questions

Does wearing a sports bra at night cause breast cancer?

There have been several cleverly worded campaigns conducted by bra manufacturers who would like women to believe there is no scientific evidence suggesting their products cause or contribute to breast cancer. However, it has not gone entirely unnoticed by scientific professionals that when women choose to wear a bra twenty-four hours a day and when sleeping, isn’t the best route for their health and wellness.

At least not according to past studies conducted through Duke University, which made the link between wearing bras and causing breast cancer more apparent and found other factors that contributed to the disease’s development.

Can sports bras damage your breasts?

Bras do support your bust. When exercising and playing sports, the breasts are held together by fatty and connective tissue. Constant stretching can result in injury over time, which can cause pain to your connective tissue. Bras that offer a lot of support avoid this issue and any potential discomfort or pain caused by worn-out sports bras that have lost their elasticity.

What are the side effects of not wearing a bra?

Not wearing a bra can result in almost as many problems as having too much caffeine before bed. Women are among the few rare species that willingly go without them (whales, spotted hyenas, and other mammals are on that list too). We know it sounds crazy, but we’re here to remind you there’s something wrong about it because, believe it or not, breasts belong on the body for reasons like a natural cushion or general health purposes.

The final point is that gravity is impartial, and unfortunately, gravity doesn’t take days off from working whether you’re wearing a bra or not, so over time, they will sag regardless of what happens to them.

Are sports bras good for a teenage girl?

Sports bras are suitable for teenage girls as they help support their developing breasts. Adolescent girls still developing their breasts require a good sports bra to protect their delicate breasts while performing rigorous activities. Manufacturers have designed sports bras with adjustable straps to aid teenage girls in supporting their tender breasts optimally.


Never make the mistake of sleeping with a regular bra, as this could be detrimental to your health. While wearing a sports bra could potentially be something done for comfort, it could be best if you avoid sleeping with a bra that pinches your skin or one that fits tightly. It is not a bad idea to wear your sports bra to bed, but if the fit is tight, you will be uncomfortable, and it is not worth it. Always ensure that the bra you wear to bed supports your breasts optimally and provides sufficient comfort.
