A viral TikTok tip has revealed a simple and budget-friendly hack to cool down 'super fast' at night during hot weather, using nothing more than a couple of flannels or face cloths. The trick, shared by Laura from the running group Muddy Soles Club, has amassed over 200,000 views and garnered praise from viewers eager to try it.
How the frozen flannel trick works
To cool down quickly while sleeping, the method involves drenching two flannels in water, squeezing them out, and placing them in the freezer about an hour before bedtime. Once frozen, the cloths are kept next to the bed. If you wake up feeling overheated during the night, you can lay them on the back of your neck or your stomach.
Laura explained in the clip: 'No fan, no aircon. Try this heatwave sleep hack.' She added: 'Trust me, it cools you down super fast and makes it so much easier to get back to sleep.'
Why hot weather disrupts sleep
According to the post, hot weather can interfere with sleep because the body needs to lower its core temperature to fall asleep. When overheated, the brain is 'fooled' into remaining awake, leaving you feeling less sharp the next day. This hack aims to counteract that by providing direct cooling to key pulse points.
Viewer reactions and alternative tips
Viewers in the comments section agreed the trick worked well. One wrote: 'Oh this is a good one.' Another said: 'I'll be trying this tonight.. I can't sleep with the noise of the fan.' A third commented: 'Must try this!' Others shared their own tips, with one suggesting: 'I've been putting the hot water bottle in the freezer then taking it to bed.'
The hack offers a low-cost alternative to fans or air conditioning units, which can be noisy or expensive to run. As warm weather continues to affect the UK, this simple method provides an accessible way to improve sleep quality.
