'Brilliant at keeping the bedroom cool and dark' – this £6.50 Dunelm buy has shoppers raving about the difference it's made to their sleep during the heatwave

A colourful bedroom with dormer windows and pale pink walls. The double bed is dressed in white bedding with yellow, pink and burgundy accents.

The UK has just celebrated the summer solstice, the day with the most daylight hours of the year, and on top of that, many parts of the country are currently experiencing a heatwave with temperatures predicted to soar to 36°C to 40°C.

That's a *lot* of heat and light, and whilst we don't want to wish away the summer weather, there's no denying that when it comes to how to sleep better, a bedroom that's too hot and too bright can play havoc with a good night's rest.
