How hot will the heatwave be at night and how do I stay cool enough to sleep?

Since Monday, parts of the UK have been under an amber heat warning and a rare red warning will be in place throughout much of England early next week. The Met Office has said that in red zone areas, there is a 50% chance temperatures will hit 40°C during the day.

Temperatures are also set to remain high overnight, particularly in urban areas. There is a high likelihood of tropical nights – when minimum temperatures don’t drop below 20°C – for some early next week.

How can I keep cool at night?

  • Cool your body down by having a cold shower before bed

  • Stay hydrated throughout the day - dehydration can cause sleepless nights

  • Maintain air flow in your bedroom during the day by using a fan or keeping your windows and doors open

  • Reduce your bedding – but remember that, however hot it is in your bedroom, your body temperature will fall during the night so keep covers handy

  • Put your pillowcases and sheets in a sealed bag in the freezer and dress your bed ten minutes before you want to sleep

  • If you really can’t doze off, get up and do something calming such as reading or writing. Only return to bed when you feel sleepy.
