When we drift off, our body temperature naturally drops to help us fall asleep. But during a UK heatwave, a hot bedroom can interfere with this process, leading to:

Sleep experts suggest the ideal bedroom temperature is between 16 and 18°C, which can be difficult to maintain during warmer weather.

Top Tips for Sleeping in Hot Weather

If you are struggling to sleep in the heat, these simple tips can help you stay cool overnight:

1. Choose Breathable Bedding

Opt for lightweight cotton or linen sheets that allow air to circulate and help wick away moisture.

2. Keep Your Bedroom Cool During the Day

Close curtains or blinds to block out direct sunlight and reduce heat build up.

3. Take a Lukewarm Shower Before Bed

Avoid cold showers, as they can increase your core temperature afterwards. A lukewarm rinse is more effective.

4. Stay Hydrated

Drink plenty of water throughout the day but avoid large amounts right before bed to limit disruption.

5. Use a Fan Effectively

Position a fan near an open window in the evening to help circulate cooler air around the room.
