Getting to sleep during pregnancy can be incredibly difficult. Between aches, pains, cramps, and simply accommodating the baby growing inside you, insomnia is something that many pregnant mothers experience at some point or another.

One of these accommodations all mothers have to adapt to is the changes that happen in your breasts. Breasts begin growing very early on in pregnancy and may quickly become tender, sore, and sensitive, causing frequent discomfort and difficulty sleeping.

But should you wear your bra at night when pregnant?

Replace Your Underwire Bra With Something More Comfortable

Even if your bra is not bothering you during the day, it is recommended to avoid wearing underwire bras to bed due to the fact that they often inhibit blood flow. In extreme situations this could hurt your ability to produce milk, although a more realistic scenario is it will simply be harder to fall asleep and stay asleep.

Sleep deprivation has been linked to developmental and growth problems of babies during pregnancy, among a number of other serious health issues.

Instead, it is recommended to invest in maternity bras – bras that are specifically designed for pregnant mothers to offer maximum comfort.

Many mothers find that they quickly outgrow their bras during pregnancy anyway, and maternity bras offer much more flexibility in this regard, making them a great choice for maximum comfort throughout pregnancy (and beyond!)

Wearing Bras At Night During Pregnancy: FAQ

Will A Maternity Bra Prevent My Breasts From Sagging?

Unfortunately not!

Can I Wear Sports Bras To Sleep While Pregnant?

Sure! Sports bras can be great during pregnancy – just be sure they’re not too tight on your breasts. As soon as they start causing any noticeable discomfort, it’s recommended to switch to a maternity bra, which is typically much more flexible as your breasts continue to grow.

Can I Simply Go Braless At Night?

Absolutely! However, many mothers avoid this because they prefer the extra support that a bra can offer, and may want something to hold pads in place to prevent breastmilk from leaking.

Does Wearing A Bra To Bed Prevent Breast Growth?

No, this is a myth. As mentioned earlier, extremely tight bras may inhibit blood flow and milk production, but they will not prevent your breasts from growing.

Is Wearing A Bra At Night Linked To Breast Cancer?

No, there is no link between wearing a bra to bed and developing breast cancer (during your pregnancy or later in life.) This is also a myth.

How Do I Choose The Best Maternity Bra For Me?

When it comes to maternity bra selection, we have a few tips:

  1. Consider getting fitted for a maternity bra, as they do not always fit the same as a traditional bra. The cup should cover your entire breast.
  2. Buy multiple bras, and launder them often.
  3. Buy a bra for the size your breasts are now – don’t leave ‘room to grow’. Accept that you may have to buy another bra set later on during your pregnancy.
