Sleeping in summer can be difficult because, let’s face it, British houses just aren’t built for the heat!
Not all of us are lucky enough to have air conditioning or a top-of-the-range fan and staying cool can become a constant battle until autumn.
For a great night’s sleep, experts say your bedroom temperature should be between 16-18ºC, but that can be impossible when the temperatures really begin to rise.
And, as part of your natural sleep cycle, your core body temperature should start to drop when it’s time to wind down. Disrupt this with an evening temperature that’s more akin to the Saharan desert and you’ve probably got a bad night’s sleep ahead of you.

What can make a difference is what you’re wearing to bed. Of course, sleeping in the nude is probably the way to go but, if you prefer a set of pyjamas or a nightdress, there are brilliant options that allow for a cooler, more restful night.
Lightweight, natural fabrics like cotton, linen, bamboo and even silk are breathable and soft on the skin and help your body regulate its temperature rather than trapping heat. The fit matters too. Think relaxed cuts, sleeveless styles, and short sets that let air circulate.
Whether you like to keep it simple or prefer something with a bit of detail, there’s a style for every kind of sleeper. Just take a look at our picks…
