I put on my comfiest clothes every night before going to sleep to have a peaceful slumber. Many also prefer to sleep without a bra since it can feel a bit restraining. However, did you know that there is a type of bra designed specifically to wear when sleeping?

So what is a sleep bra, and why should you wear one?

What Is a Sleep Bra?

A sleep bra is an incredibly comfortable, ultra-cozy undergarment that you can wear to bed for round-the-clock support. It is wireless, with light to no padding in the cups depending on your preference. It looks like a crop top with a little more structure.

Sleeping bras are the perfect lingerie for sleeping or lounging. They are especially useful for women with bigger breasts who might need all the stability they can get without the generic, constraining bra design. Moreover, it is best if you wear a bra to bed for a number of reasons! 

Why Should You Wear a Sleep Bra?

A sleeping bra is a must-have undergarment, especially if you are full-figured and prefer to sleep in your bra. I already know that it offers the ultimate comfort for a night of uninterrupted sleep. In addition, it also has the following benefits:

  • Alleviates pain
  • Provides support
  • Breathable
  • Minimizes wrinkles

Alleviates Pain

Women with larger busts understand the challenges of managing the boobs on a daily basis since they can hurt your back and strain your neck muscles. Most often, these issues can also impact your sleep, leading to restlessness and agitation. In this case, a sleep bra can be a game-changer for you.

Putting on a sleeping bra can keep your breasts positioned correctly. It also prevents too much movement as you twist and turn in your sleep and allow you to rest more peacefully. Consequently, you no longer wake up with a strained back or neck.

Provides Support

During the day, your breasts experience a vertical force of gravity, which pulls the breasts down. Thus, you need a bra to help support your breast tissues and keep them upright. At night when you lie down, your breasts fall downwards towards your chest.

A sleep bra is designed in a way that it supports your breast from moving in the direction of your armpits. It also prevents the connective tissues in your boobs from undergoing too much wear and tear, which can cause them to lose their elasticity and cause sagging.


If you are used to wearing a bra to sleep, avoid wearing the regular one that you use during the daytime. These types of bras often have padded or lined cups that do not allow your skin to breathe.

On the other hand, a quality sleep bra is made from a soft, breathable fabric that gives your skin a break from constant congestion. When your skin is allowed to breathe, it is less prone to irritation and rashes.

Minimize Wrinkles

As you grow older, your skin becomes thinner. It loses its flexibility and ability to bounce right back after stretching. After a long night of sleep, you may experience cleavage wrinkling that may not go away as soon as you wake. 

A sleeping bra can reduce the chances of wrinkles developing on the skin. It can also protect your chest skin from stretching too much as you move around in your sleep or when you sleep on your stomach.
