The Truth about Sleeping with a Bra

  • Save

For decades, women have debated whether it’s beneficial or harmful to wear a bra while sleeping. This simple question has sparked numerous myths, old wives’ tales, and conflicting advice from various sources.

Myth #1: Wearing a bra to bed prevents sagging

One of the most common myths about sleeping in a bra is that it helps prevent breast sagging over time. Many women believe wearing a supportive bra 24/7 keeps their breasts perky and youthful. In truth, breast sagging is primarily determined by factors beyond our control, such as genetics, age and gravity, breast size and shape, and hormonal changes.

While wearing a supportive bra during the day can help minimise bounce and strain on the breast tissue, wearing one at night doesn’t significantly impact long-term sagging.

Myth #2: Sleeping in a bra increases the risk of breast cancer

This myth often stems from the idea that bras restrict lymph flow and trap toxins in breast tissue. However, the American Cancer Society has stated that there is no credible research linking bra-wearing habits to breast cancer development, regardless of the type of bra worn, how tight it is, how long it’s worn, or whether it’s worn during sleep.

Myth #3: Sleeping in a bra is always uncomfortable

While some women may find sleeping in a bra uncomfortable, others prefer it. The comfort level largely depends on the individual and the type of bra worn. Soft, wireless bras or sleep bras explicitly designed for nighttime wear can be comfortable for some women.

Potential Benefits of Sleeping in a Bra

While there’s no definitive evidence that sleeping in a bra is necessary or beneficial for most women, some may find advantages in this practice:

  • Comfort for larger breasts: Women with larger breasts might find that wearing a soft, supportive bra at night helps reduce discomfort and movement during sleep.
  • Support during pregnancy and breastfeeding: Pregnant and nursing women often experience breast tenderness and enlargement. A comfortable sleep bra can provide support and reduce discomfort during these periods.
  • Active sleepers: Women who toss and turn at night might prefer the added support and reduced movement a sleep bra provides.
  • Post-surgical support: After breast surgery, doctors may recommend wearing a soft, supportive bra 24/7 for a certain period to aid in healing and reduce swelling.
Potential Drawbacks of Sleeping in a Bra

While sleeping in a bra isn’t inherently harmful, there are some potential drawbacks to consider:

  • Skin irritation: Wearing a tight or ill-fitting bra to bed can cause skin irritation, rashes, or even fungal infections in the warm, moist environment under the breasts.
  • Disrupted circulation: A too-tight bra can restrict blood flow and lymphatic drainage, leading to discomfort or swelling.
  • Disrupted sleep: For some women, wearing a bra at night might be uncomfortable and interfere with quality sleep.
Choosing the right type is crucial for comfort and potential benefits if you sleep in a bra.
Here are five tips:
  • Opt for soft, wireless bras: Use breathable, natural fabrics without underwires or hard seams.
  • Ensure proper fit: A sleep bra should be snug but not tight. Avoid bras that leave marks on your skin or feel constrictive.
  • Consider sleep-specific bras: Many brands now offer explicitly designed for sleeping, prioritising comfort and gentle support.
  • Replace regularly: Like all bras, sleep bras can lose their shape and supportiveness over time. Therefore, they should be replaced regularly to ensure optimal comfort and fit.
  • Avoid excessive padding: Lightly padded or unpadded bras are usually best for sleeping, as excessive padding can be uncomfortable and unnecessary.
The Bottom Line

Ultimately, the decision to sleep in a bra is a personal choice that depends on individual comfort and preferences. No solid scientific evidence suggests that it’s either necessary or harmful for most women. If you find it comfortable and prefer the added support, there’s generally no reason not to wear a bra to bed. However, if you find it uncomfortable or restrictive, feel free to go bra-free at night without worrying about negative consequences.
