Is It Bad to Sleep in a Bra? Here's What OBGYNs Think

To sleep in a bra or not to sleep in a bra, that is the question. Those who go to bed with a little extra support claim it's better for your overall breast health, while those who don't say that our chest needs the freedom to breathe at night after a long day of being constrained. So which way is the right way? And does sleeping with or without have an impact on your health? We asked the expert for their thoughts.

Ahead, learn about the pros and cons of keeping your chest wrapped up at night.

Is It Beneficial to Sleep in a Bra?

If you find bras comfortable, then yes, it’s beneficial to sleep in them. In fact, according to fertility specialist and board-certified OBGYN Dr. Lucky Sekhon, sleeping in a bra can reduce discomfort related to breast swelling—whether due to hormonal changes, engorgement during breastfeeding, or when trying to wean off of breastfeeding. 

As wonderful as comfort is, we know you might also be wondering if wearing a bra to bed can help prevent breasts from losing elasticity and, ultimately, dropping a bit from their current position.

“While some women may be more comfortable wearing a bra to bed, there is no proof that continued support through the night has any significant effect on breast tissue,” says breast surgeon Dr. Heather Richardson. “There have been attempts to both prove and disprove that wearing a bra either saves the internal ligaments from fatiguing with its support or that keeping the tissues from ‘working’ to support themselves makes them too weak and soft.” But, at the end of the day, she says it seems that good old fashioned genetics, along with patterns of breastfeeding, has far more influence on how breast shape and appearance are maintained over time—not whether or not you wear a bra to bed.

Side Effects of Sleeping in a Bra

Just like there are no major benefits of sleeping in a bra, there are also no major negative side effects. “Contrary to the common rumors, sleeping in a bra does not impair blood circulation, cause breast cancer, stunt breast growth, etc.” Sekhon says.

While wearing a bra to bed can’t lead to serious health problems, okko CEO and founder, Phoebe Kunitomi, points out that doing so can cause potentially skin issues. “Wearing a dirty bra can accumulate oil, sweat, and bacteria and result in skin irritation or acne—during the day and at night,” she says. Because of this, whenever you wear a bra—to bed or otherwise—it’s important to regularly wash it to avoid any such issues. If you opt to wear a bra to bed, make sure it is a fresh one, and not the same one you wore for hours.

Wearing a Bra During the Day

Despite what many lingerie companies would have you believe, Richardson says that, other than cosmetic issues, there is no reason to think you need to wear a bra in an attempt to avoid more serious breast health concerns. 

So, once again, it comes down to personal comfort. This is especially true if you’re bustier. “For those with larger breasts, bra-wearing can help with back and neck pain, however, some point out that posture and whether or not someone shrugs and stoops their shoulders has more influence over back and neck pain than the size and weight of breast tissue itself,” Richardson says. “Whether we wear a bra or not may make us feel more self-conscious about our breasts and how people see us, which spills into other areas of stance and comfort.”

And, while larger busts are on the brain, it’s worth mentioning that, as Richardson points out, women with very large breasts may see further benefits, as fabric between the bottom of the breast and the top of the upper abdomen prevents moisture from getting trapped, which could otherwise cause yeast and potentially skin fungi to grow. So, by keeping the cozy barrier, you’ll be able to reduce any possible skin irritation.

The Final Takeaway

Our experts agree that wearing a bra to bed is entirely a matter of personal preference. As long as you wear a clean bra that is comfortable and doesn't disrupt your sleep level, it should not affect any part of your lifestyle.
