The silk, linen and cotton nightwear that will keep you cool as temperatures hit almost 40 degrees

The record for the hottest temperature in the UK measured at 38.7C in 2019 is expected to be broken this summer, according to forecasts.

Experts have begun sharing their advice for how to avoid tossing and turning at night during the heatwave - while also warning that shorter summer nights could give the body fewer natural cues to switch off.

“Sleeping in the heat can be a real nightmare, we are constantly throwing off the duvet, twisting and turning and trying to find the “cool” side of the pillow, all of which affects the quality of the sleep we get,” Silentnight Sleep Expert Hannah Shore said.

“If you have difficulty sleeping during the warmer months, you should consider having a different duvet for summer and winter. Your summer duvet should be a lightweight duvet, and if you’re still too warm to sleep, this can be swapped for a sheet.

“You should also ensure your bedding is made from breathable fibres. Natural fibres are good at temperature regulating however, some people find these materials a little heavy. If that’s you, opt for polyester, as these will offer you a breathable sleeping environment but will not be as heavy.”

Hannah explained that sounds such as rainfall or bird song have a lack of rhythm which encourages the brain to relax, while scents like lavender can help to relieve anxiety and create a stress relieving environment for sleep.

She said blackout blinds can improve the quality of sleep as they prevent light disturbance and being out in nature during the day has been shown to improve overall mood, which helps us to fall asleep easier.

Hannah added: “Sleep is a huge contributing factor to living a healthy, happy life. Making sure your sleep environment is beneficial to your own sleep preferences is essential, but adding an element of nature to your bedroom is a great way to incorporate a sense of relaxation, and help the mind switch off every night.

“Whether you add a selection of plants to the bedroom, or simply making sure you are getting outside for at least fifteen minutes a day, nature holds the key to a great sleeping pattern.”

Having transformed your bedroom into a tranquil space to sleep, it’s important to consider the material of the clothes you wear to bed.

Rather than sleeping naked, which can make you feel warmer as sweat collects on the body, try these nightwear items made from natural fibres that regulate body temperature.
