What is a sleep bra and should we all be wearing one?

Whether you’re a PJs kinda gal or you prefer to sleep sans smalls, chances are you’ll take off your bra before you get into bed.

But now an actual bedtime bra has been created for those who prefer to give their boobs a little bit of support while they’re in the sack.

Luxury lingerie company Lunya claim that wearing their “Siro sleep bralette” may actually be comfier than throwing on your nightie without anything beneath it.

Priced at $50 (approx. £38), the bra-come-crop-top has a racer back and is made from super-soft, modal fabric, making it way more sleep-friendly than your usual under-wired offerings.

If you’re like most women, you dream about the moment you can step through your door and free your boobs from their underwire incarceration.

And while a boulder holder is an every day essential do we really need to don a bra while we’re sleeping, no matter how comfy?

For some women wearing a bra to bed is about offering a little extra support, for others it’s about trying to stop the sagginess.

But can a sleep bra really help with that?

“The premise of a sleep bra is that it keeps the shape of the breasts during sleep,” explains Consultant cosmetic surgeon Gary Ross, of BMI The Alexandra Hospital.

“However, there is no evidence that using one will decrease sagging – that’s an effect of gravity and ageing.”

Ross says that though some women with larger breasts who struggle with back pain do report that sleeping in bra ease these symptoms, wearing a sleep bra won’t actually prevent sagging, and in some cases could exacerbate things heading south.

“In general, it is believed that the restrictive material of bras may actually encourage breasts to sag by preventing muscle and ligament development,” Gary Ross explains.

“A bra can hold up the breasts to provide a shape and look that women wish for, but it can’t prevent sagging.“

For those who do decide to wear a bra to bed, Gary Ross suggests making sure it is comfortable and well-fitted.

“I’d recommend not using an underwired bra, which could lead to pressure around the wire as you move in different positions in your sleep, leave an imprint and could even induce irregularities that manifest as back rolls,” he warns.

“It could also lead to a restricted blood flow, disruption of the lymphatic drainage system and associated swelling above and below the bra.

The bottom (or boob) line: No, you don’t need to wear an actual sleep bra, to sleep in, unless of course you want to.

For the makers of the Siro sleep bralette, the bedtime bras are just as much about offering women some non-underwire support while they pootle around the house.

“[Lunya] is what you wear when you get home from work,” Ashley Merrill from Lunya tells the NY Post. “It might not be exactly what you sleep in, but by layering, you don’t have to change too much before you go to bed.”
