After weeks (read: months) of damp, dark weather, the sun has finally come out to play here in the UK. Yes, a heatwave is upon us and, while that means happy days spent in the local beer garden, on your sun-drenched balcony, or at the beach, the nights aren't so, well, pleasant.

Between sticky sheets and even stickier skin, nights in the UK during a heatwave are undeniably sweaty. Sadly, most of our homes just aren't equipped for the warmer temperatures – after all, we need them to keep the heat in for most of the year – so come nighttime in a heatwave, the air is stuffy, and our sheets are drenched. It's why so many of us religiously sleep with a fan on, even though health experts advise against it.

To that end, making tweaks to your sleeping arrangements – like switching out your bed sheets for breathable cotton options and opening your windows only once the sun has gone down – are essential. Beyond what's on your bed, what you're wearing to bed can make a massive difference as well. Enter: cooling pyjamas.

Marks and Spencer's Cool Comfort™ Cotton Modal Shortie Set has been specifically designed to help keep you cool when you go to bed, whether you're battling a heatwave or hormonal hot flushes. For that, you can thank the Cool Comfort™ technology. The short-sleeved top and shorts, which are from the brand's Autograph range, will also help keep those night sweats at bay, and the elasticated drawcord waist on the shorts is super comfy, too! But just because these pyjamas are functional, it doesn't mean they're not stylish. The navy and white colour palette gives major nautical holiday vibes.

"Cool and comfortable pjs which have been a godsend," one five-star reviewer said of this set. "I wanted something that was cool enough but comforting to wear in bed. Stylish as well!"
