UK Heat Records ‘Annihilated’ Today: 3 Survival Hacks to Sleep Comfortably During Dangerous ‘Tropical Nights’
Britain’s ongoing heatwave has broken records, with overnight temperatures staying unusually high. Many people are struggling to get a good night’s sleep. According to the Met Office, temperatures at Kenley Airfield in south London did not drop below 21.3°C overnight. This made it the warmest May night ever recorded in the UK. The figure surpassed previous records and points to a growing weather trend that experts say could happen more often in the coming years. This milestone is important because it qualifies as a “tropical night,” which means temperatures remain above 20°C all night. While this term might seem harmless, health experts warn that these conditions can put extra stress on the body, especially during long heatwaves.
Why Tropical Nights Can Be Harmful
Most people cool down before they fall asleep. Usually the body’s core temperature drops one to two degrees, which helps you get deeper, more restorative sleep. If it stays elevated overnight, it’s harder to cool down and often leads to restless sleep, waking many times during the night, dehydration, fatigue and more discomfort the next day. The risks are greater for older adults, young children, pregnant women and those with heart or respiratory conditions. Public health officials have repeatedly warned that long periods of extreme heat can increase the risk of heat-related illnesses. The overnight record follows daytime temperatures that soared to 34.8°C at Kew Gardens, breaking a May record that had stood for over a century. Forecasters say temperatures could rise even more as the heatwave continues.
Three Simple Ways to Sleep More Comfortably During Hot Nights
While nobody can control the weather, sleep specialists say a few practical adjustments can make a noticeable difference.
1. Cool Key Areas of the Body Before Bed
Applying a cool, damp cloth or cold pack to pulse points can help lower body temperature more quickly.
Focus on areas such as:
- Wrists
- Neck
- Elbows
- Ankles
- Behind the knees
Because blood vessels sit closer to the skin in these locations, cooling them may help reduce overall body heat and improve comfort before sleep.
Some sleep experts also recommend placing a damp cloth on the forehead for additional relief.
2. Keep Heat Out During the Day
One of the biggest mistakes people make during a heatwave is letting sunlight heat their bedroom all day. Closing curtains, blinds, or shades before the hottest part of the afternoon can greatly lower indoor temperatures. If the outside air is hotter than inside, keeping windows closed can also help stop more heat from getting into the room. Dark rooms stay cooler for longer, which leads to a more comfortable sleeping environment later in the evening.
3. Choose Lightweight Clothing and Bedding
Heavy blankets and synthetic fabrics can trap heat and make sleeping even more uncomfortable. Experts recommend:
- Loose-fitting cotton sleepwear
- Lightweight sheets
- Breathable bedding materials
- Minimal layers where possible
Some people even place pillowcases or bedsheets in the freezer for a short period before bedtime to provide temporary cooling relief.

A Sign of a Warming Climate
Meteorologists observe that tropical nights used to be quite rare in much of the UK. However, in recent years, there have been several notable instances, especially during the record-breaking heatwaves of 2022. Beyond personal discomfort, extended hot weather can strain healthcare services, lower productivity, and raise energy demand as households try to stay cool. The Met Office has issued heat warnings for various parts of the country, with forecasters suggesting that unusually high temperatures may last for several more days. For many Britons, the biggest challenge may not be surviving the daytime heat; it may be finding a way to sleep at night while temperatures remain stubbornly high.
FAQs
What is a tropical night?
A tropical night occurs when temperatures remain above 20°C throughout the night. Such conditions can make it harder for the body to cool down and recover during sleep.
Why is sleeping difficult during a heatwave?
The body needs to lower its core temperature before entering deep sleep. High overnight temperatures interfere with that process, often leading to restless and interrupted sleep.
What was the UK’s hottest May night on record?
The Met Office reported that temperatures at Kenley Airfield in London remained above 21.3°C overnight, making it the warmest May night ever recorded in the UK.
Are cooling pulse points effective?
Sure. You can use cool packs or damp cloths on pulse points like your wrists, neck, and ankles to lower your body temperature and feel more comfortable before going to bed.
When will the current UK heatwave end?
Heat warnings are in effect across parts of the country as weather forecasts suggest the unseasonably warm conditions could continue for several days.
