In recent years, the question of whether to wear a bra to bed has become a hotly debated topic. On one hand, there are those who believe the added support for the breasts can promote good posture, reduce back pain, and even increase blood circulation in your boobs.

On the other hand, some people argue that wearing a bra for an extended period of time can cause discomfort, breathability issues, and even allergic reactions. So, what are the real benefits and drawbacks of wearing a bra to bed?

Let's dive in and find out.

The Breast Health Benefits of Wearing a Bra to Bed

First things first, the benefits:

Benefit #1: Comfort

Wearing a bra to bed can provide you with additional comfort and support while catching Zzzs. This is especially beneficial for those who have larger chests, as bras can help alleviate discomfort caused by unsupported breasts during slumber. 

Additionally, wearing a bra (in the right bra size) to bed may reduce the risk of skin irritation on your chest and back due to friction or chafing when shifting around in bed. A bra can also help absorb moisture — as long as the proper material is used. So, if you want to summon the Sandman in a bra that absorbs moisture? Avoid silk and stick with one made of cotton, preferably OEKO-TEX Certified cotton.  

Benefit #2: Temperature Regulation

Wearing a bra to bed at night can help regulate your body temperature by providing an extra layer of insulation against the cold air. This is especially beneficial if you tend to experience hot flashes or if your bedroom tends to be on the colder side. 

Additionally, bras also provide protection from heat in summer months when sleeping with fewer clothes might be more comfortable.

Pro Tip: For a snuggly bra that’ll help to keep you warm, look for cozy fabrics like French Terry and cotton. Prefer something a little cooler? Look no further than TENCEL™ Modal

Benefit #3: Improved Circulation

Wearing a bra while you sleep can promote improved circulation, which can reduce swelling and help promote better overall blood flow throughout your body.

This is particularly beneficial for those who have experienced mastectomies and need additional support for their chest area following surgery. For example, those recovering from a unilateral mastectomy might find a Holdster Bra to be just what they need.  

Benefit #4: Better Posture Support

Certain posture bras can provide additional support to your back and chest area while you sleep, which can help improve posture. This is beneficial for people who tend to experience neck or back pain due to poor sleeping posture. Wearing a bra to bed may help prevent slouching, which can be caused by unsupported breasts during sleep.

Benefit #5: Absorbs Moisture

As bras absorb sweat and oils from the body throughout the day, wearing a bra to bed at night can help keep your skin drier and reduce bacteria growth that could lead to fungal infection or irritation in sensitive areas like the nipples. 

Additionally, opting for a breathable fabric like cotton or a TENCEL™ Modal bra can further enhance hygiene, as these fabrics allow more ventilation than synthetic materials. 

The Drawbacks of Wearing a Bra to Bed

And now onto the drawbacks:

Drawback #1: Uneven Breast Support

Depending on the type of bra you choose to catch Zzzs in, it can provide an uneven level of support for your breasts. This can cause both short and long-term breast pain and possible discomfort while sleeping. Wearing a bra to bed may be more beneficial if you choose one with minimal padding that won't compress your breast tissue too much.

Drawback #2: Breathing Issues

When you have issues with a bra fitting your breast shape and breast size correctly, you might not be able to breathe as well at night. It might be time to go back to the drawing board — aka the sizing chart to re-check your bra size.

Safety always comes first: Bra bands that don’t fit can constrict ribcage. They also limit airflow during sleep, potentially resulting in breathing problems or even snoring. 

If you already suffer from a respiratory condition, wearing a tight-fitting bra at night is not recommended. 

Drawback #3: Skin Irritation

When worn to bed, even the most comfortable bras can cause friction and irritation on your skin. Wearing a tight-fitting or ill-fitting bra can dig into your skin and leave indentations. In addition, wearing a tight and dirty bra can lead to rashes, itching, and other uncomfortable skincare issues.

Pro Tip: If your skin is especially sensitive, stick with fabrics like TENCEL™ Modal, which is naturally hypoallergenic. It’s also not bleached or dyed, so you can sleep soundly without any worry of toxic chemicals causing irritation to your skin.  

We want to throw a myth-busting statement here: some people in the past have suggested that wearing underwire bras while sleeping can contribute to breast cancer. So far, science disagrees, saying that underwire bras have no relation to breast cancer

Drawback #4: Uncomfortable Material

Many types of bras, such as certain sports bras, are made with synthetic material that may be too heavy or hot when worn to bed. Sleeping in cotton or lightweight fabric is more breathable and less likely to cause any discomfort while you rest.

Go Commando

You could go commando — aka, sleep naked. According to research, snoozing in your birthday suit can cool your body to help you fall asleep faster, and it improves your overall sleep quality, too.

But that’s not all — sleeping nude is a great way to get in touch with your body and boost your self-esteem. In fact, according to one recent study, researchers found that spending time naked helped boost overall body image, which, if you ask us, is definitely a win when it comes to embracing self-love!

The Final Word

So, is it ok to wear a bra to sleep? 

There are quite a few wellness benefits to catching Zzzs in a bra. That said, it's vital to be mindful of the potential drawbacks when deciding whether or not to wear one to bed. While some people may find sleeping in a bra more comfortable, there are a few issues that can arise from doing so. 

In order to get the most restful sleep possible, perhaps opt for loose-fitting and breathable clothing such as sleep bras, comfort shirts, and tanks instead. Doing this will help ensure you get the best quality of sleep possible without risking any negative side effects associated with wearing a bra while you snooze.
