Benefits and drawbacks of wearing a bra while you sleep

You don’t have to wear a bra to sleep? Technically it is not necessary. When you’re lying flat, a soft, elasticized bra can make you more comfortable and support you over the night.

Back pain relief

The use of a bra to support the back can help with some back problems, especially the upper back, and lead to more restful sleep.

Improved sleeping

A bra can help women sleep better; so many women opt to wear it. A bra that supports your breasts is comfortable can help you feel more confident, especially if you have larger breasts.

Cons of wearing a bra to bed

Health and medical issues

Circulation Issues

There are many important anatomy details around the chest area. A tight bra can restrict blood supply to the breasts and other areas. This can cause arm pain or even numbness.

Skin irritation

When you toss and turn in the night, hooks, lacing, or other parts of your bra rub, it can irritate. It can lead to irritation and rashes if you rub your sensitive breasts too often. Ouch.

Hyper pigmentation

If the skin is constantly under pressure like a bra band or strap, it can become darker and more swollen.

Breast Fungus

Excessive sweating can be a breeding ground for breast fungus. This is an aggressive skin infection that requires medical attention. This risk is magnified by wearing a bra while you sleep.


Skin irritation can disrupt sleep and lead to restlessness. The same goes for underwire bras. It can impact your sleep quality regardless of whether you realize it.

It is ultimately up to you. The main reason women opt to wear bras to bed is that there’s no evidence to show that they make their breasts feel firmer.

Tips for Finding the Perfect Size and Fit

The band should not be too tight or too loose.

The right size band should allow you to comfortably fit your finger between the strap and your back with just a few inches of stretch. If the underwire is digging into your breast tissue, then your band is too small. Support is important, so it’s not better to be loose. People mistakenly believe that looser means more comfort (think caftans and sweatpants), but this is not true for bras. The band holds the breasts up most effectively, so a loose bra that sits between your shoulders will not give you the support you require and make you feel less comfortable.

Different bra styles and materials serve various purposes.

Your bra options should match your outfit. Styles that can be worn from day to night should be versatile and comfortable. Multiple bras are important to avoid overstretching a bra. Experts I spoke with agreed that everyone should own at least:

Two traditional bras in the style of a T-shirt bra or a black bra, which would cover 70 to 80 percent.

A sports bra which minimizes bounce and doesn’t hinder your performance. Different bras might be better for different activities, such as running or yoga, but they may not provide the same level of support. You might also need several bras if you exercise a lot.

Convertible bras that can be strapless or racer back halter or crisscrossed for tops with unusual necklines and formal occasions.

A bralette or bralette that is not under wired, which you can wear while traveling or lounging. To get the perfect fit, make sure the straps can be adjusted.
