5 Simple Ways to Sleep Better During a Heatwave

The UK isn’t exactly designed for extreme heat. Most homes trap warmth throughout the day, bedrooms become stuffy by evening, and trying to sleep can quickly turn into a frustrating battle of tossing, turning, and flipping the pillow over for the hundredth time.

The problem is not just discomfort either. Warmer temperatures can genuinely affect sleep quality, making it harder for your body to fully switch off and properly rest.

The good news? A few simple adjustments can make a surprisingly big difference.

1. Keep Your Bedroom Cool Before Nightfall

One of the biggest mistakes people make during hot weather is trying to cool the room down at bedtime. By then, the walls, floors and furniture have already absorbed heat throughout the day.

Instead, try to prevent the heat building up in the first place.

Keep curtains or blinds closed during the hottest hours, especially on windows that get direct afternoon sunlight. Blackout curtains or thicker lined blinds can help reduce indoor temperatures noticeably.

Then, once the temperature outside begins to drop in the evening, open windows to let cooler air circulate through the room.

2. Swap Heavy Bedding for Breathable Fabrics

A thick duvet might feel cosy in winter, but during a heatwave it can quickly become unbearable.

Lightweight cotton sheets or linen bedding tend to work far better in warmer conditions because they allow air to circulate and help wick moisture away from the skin.

Synthetic fabrics often trap heat and humidity, making nights feel even warmer than they already are.

If you still like having something over you while sleeping, a light cotton throw is usually enough without overheating the bed.

3. Open Windows at the Right Time

It sounds obvious to open windows when it’s hot, but timing matters.

Opening windows during the hottest part of the day can actually make the room warmer by allowing hot air inside. Instead, it is usually more effective to keep them closed during peak daytime temperatures and open them later in the evening once the outside air cools down.

If possible, create a cross breeze by opening windows on opposite sides of the house or room. Even a small airflow can make a noticeable difference overnight.

A fan placed near an open window can also help pull cooler evening air indoors rather than simply circulating warm air around the room.

4. Cool Your Body Before Bed

Your body naturally lowers its temperature before sleep, but during a heatwave that process becomes harder.

A lukewarm shower before bed can help encourage your body to cool down naturally. Surprisingly, ice-cold showers are often less effective because they can trigger your body to generate more heat afterwards.

Another simple trick is cooling your wrists, feet or neck with cold water before getting into bed, as these areas help regulate body temperature more efficiently.

5. Avoid Habits That Make Heatwave Sleep Worse

Certain evening habits can make sleeping in warm weather much more difficult without people realising.

Alcohol, for example, can disrupt sleep quality and raise body temperature overnight. Heavy meals late in the evening can do the same.

It is also tempting to nap after a poor night’s sleep, but long daytime naps often make it harder to fall asleep later on, continuing the cycle.

Sticking to a normal bedtime routine as much as possible usually gives your body the best chance of adjusting.

Final Thoughts

Heatwaves can make sleep difficult, especially in homes that are built to retain warmth rather than release it. But small changes to your bedroom, bedding and evening routine can genuinely improve comfort and help you sleep more effectively during hot weather.

Sometimes it is not about making the room freezing cold — just helping your body cool down enough to properly rest.
