Too hot to sleep? Here’s how to stay cool in bed

Sweltering summer nights ruining your sleep? Check out these simple tricks and miracle products to banish the heatwave from the bedroom

All year long most of us dream of a hot summer, but when the weather suddenly becomes freakishly warm, it can play havoc with our sleep. While most of us lap up the sunshine during the day, those long hot nights are notable for the absence of shut-eye. After a few hours of tossing and turning, we all want to know one thing – what can we do when it’s too hot to sleep?

Too hot to sleep - try a bedroom fan

‘A baking bedroom can impact on our comfort,’ agrees Simon Williams of the National Bed Federation (NBF).

‘Your body temperature needs to drop slightly before you go to bed, which is why you just can’t sleep when you’re too hot.

‘An ideal bedroom temperature should be around 16 to 18°C, so it can be difficult to get comfortable in a hot and stuffy space, which leaves many people suffering from a disturbed night’s sleep.’

Fortunately, there are some amazing ways to stay cool when it’s too hot to sleep. From cooling pillows to creating airflow, try these simple and effective steps to ensure you stay cool and comfortable in bed this summer.

Keep out the heat and encourage airflow

  • Open as many windows and doors as possible to allow air to circulate. Even cracking windows at the front and the back of a house creates a slight through draft that will pull warm air out and allow the rooms to cool.
  • Keep curtains or blinds drawn during the day to keep the sun out. Blackout blinds were made for this sort of weather and shutters will also come into their own, blocking the light while letting in the air.
  • If you’ve got an attic, try opening the hatch. Hot air rises and this will give it somewhere to go.
  • Lights and appliances can generate a lot of heat, so turn them off unless you need them.

Cool bed sheets - How to stay cool in bed

Cool your bed

  • Get rid of thick duvets and blankets – ideally use a cotton sheet, but if you have to have a duvet, go for the lowest tog rating you can find.
  • Opt for natural materials in your bed and bedding. Man-made polycotton, acrylic and viscose are essentially made of plastic, so they can’t absorb moisture or conduct heat away from your body. One hundred per cent cotton sheets are a gift for hot nights. And check out Hypnos for a fab range of natural bedding buys, too.
  • Fill a hot water bottle and put it in the freezer before you go to sleep.
  • Cool a pillowcase in the fridge before bedtime or try one of the new cooling pillows that are available to buy. Filled with a temperature reactive gel, the pillows absorb excess heat, drawing it away from your body and cooling your skin.
  • Another great trick is putting your bed sheet in the fridge or freezer (use a zip-lock bag to keep it dry). Take it out just before you’re ready to sleep and it will be perfectly chilled.

Dress for the occasion

  • Wear light cotton nightwear. This is actually better than wearing nothing at all, as natural fabrics will absorb any perspiration.
  • Cool socks in the fridge and wear them. Cooling your feet lowers the overall temperature of your skin and body.
  • If you’ve got long hair, tie it back. Hair around your neck can make you feel warmer.

Try out some cool technology

  • Use an electric fan (this one from Aldi is rather beautiful!). Quiet tower fans with timers and a choice of settings are the smart choice if you struggle to fall asleep, but desk fans and pedestal fans will do the job nicely, too. If it’s really hot, put a shallow bowl of iced water in front of the fan to cool the air.
  • Next time you buy a new bed, look out for one that incorporates new temperature regulating technology.

Look after yourself

  • Have a cool shower or bath before bedtime to lower your core body temperature.
  • Drink plenty of cold water during the evening and keep a glass by the bed.
  • Avoid too much caffeine, alcohol or a big meal. They can all make you feel hot and steamy in the middle of the night through dehydration and over-active digestion.
