How a HOT water bottle can help you sleep through the heatwave – if you use it right | The Sun

FANS, spray bottles and freezing sheets – Brits will go to all sorts of lengths to stay cool at night during a heatwave.

But it’s unlikely they’ve thought to look for their dusty hot water bottle in the cupboards.

A hack that has gone viral shows how useful the winter accessory can be in the middle of a scorching summer. 

In a clip posted on TikTok that has been viewed more than 2.7 million times in two days, user @keats67 showed how she uses one to sleep in a heatwave without air con.

It showed her filling up a bottle with tap water and placing it in the freezer.

Once it’s gone hard, she takes it out and wraps it in a tea towel before placing it in her bed.

Are you drinking enough water during the heatwave?

The trick isn’t new, but viewers were left astonished they hadn’t thought of it yet.

Warnings

Other experts have warned of the risks of the hot water bottle hack because the rubber can be stretched and then burst in the future.

This could be seriously dangerous if there is hot water inside.

Rebecca Challinor, a product specialist at the retailer Terrys explained to Ideal Home: “Whilst freezing your hot water bottle can be an effective way to have a better night’s sleep in hot weather, it’s advisable once you’ve done this to no longer use the same water bottle during the winter.”

NHS hot weather advice

  • Have cool baths and showers
  • Drink cold drinks regularly and avoid alcohol, caffeine, and drinks high in sugar
  • Plan ahead to make sure you have the food, fluids, and medication you need
  • Identify the coolest room in your house so you know where to go to keep cool

  • Check on friends, neighbours and relatives who may be less able to look after themselves
