As the UK faces its first 2025 heatwave, many are tossing and turning in the sweltering nights. But scientists suggest a quirky solution: wear socks to bed. Despite seeming counterintuitive, this hack helps you fall asleep faster, sleep longer, and stay cooler—even in temperatures up to 23°C.
Why Do Socks Work?
Our bodies prepare for sleep by lowering core temperature, usually through "distal vasodilation"—sending warm blood to the skin to release heat. Professor Eus van Someren explains that warm feet signal the brain to initiate sleep. Socks mimic this process, tricking the body into cooling down faster.

The Science Explained
A 2018 Seoul National University study found sock-wearers fell asleep 7.5 minutes faster and woke up fewer times. By warming feet, socks trigger vasodilation, lowering core temperature. Dr. Michael Gradisar notes this is especially helpful for those with poor circulation.
Tips for Maximum Effect
- Timing Matters: Put socks on 1–2 hours before bed.
- Choose Breathable Fabrics: Opt for wool or cotton to avoid overheating.
- Cool the Room: Use fans or open windows while keeping feet warm.
- Shed Them Later: If too hot overnight, remove socks to boost cooling.

Alternatives for Sock Haters
If socks feel stifling, try a warm foot bath 1–2 hours before bed. Research shows a 20-minute soak in 40°C water speeds up falling asleep by 10 minutes. Professor Bill Wisden also recommends a pre-bed shower to trigger vasodilation.
Heatwave Sleep Tips
- Stay hydrated and avoid heavy meals.
- Use light bedding and close daytime curtains.
- Cool pulse points with wet cloths.

While the heatwave rages, remember: sometimes staying warm (strategically!) is the key to cooling down. Whether through socks, foot baths, or smart room adjustments, a restful night’s sleep is still within reach.
