Top 7 Tips to Cool Down Your Home and Body During a Heatwave


There’s something uniquely frustrating about a UK heatwave. The sun comes out, temperatures rise rapidly, and suddenly our homes—built to trap warmth in the winter—become uncomfortably warm. You open a window hoping for a breeze, but instead, hot air lingers like a stubborn guest.

Sound familiar? You’re not alone. When it gets this hot, the usual tricks often don’t cut it. But with a bit of strategy and some clever tweaks, it is possible to stay cool. Here are seven genuinely helpful tips to help keep both your home and yourself comfortable when the temperatures rise.


1. Let in Cool Air at the Right Time

You might think keeping your windows open all day helps, but that can backfire. The trick is to open windows early in the morning or later in the evening, when the outside air is cooler than indoors.

To create airflow, open windows on opposite sides of your home. If you live in a flat where that’s not an option, try propping doors open to help air move through the space. Even placing a fan near a window can help draw in cooler air and push warm air out. If you have an upstairs, open loft windows if it’s safe—hot air rises, and this lets it escape.


2. Block Out Heat During the Day

Once the sun starts beaming through your windows, your home heats up quickly. To fight this, keep curtains or blinds closed, especially on the sun-facing side. If you have blackout curtains, even better; they act as a barrier against the heat.

This simple change can make a noticeable difference. One reader, Sophie from Brighton, said her bedroom stayed nearly 5°C cooler during a heatwave just by keeping the blinds down until evening.


3. Use Fans Wisely

Fans are a lifesaver, but there's an art to using them effectively. A fan by itself just moves air around, but if you place a bowl of ice or a frozen water bottle in front of it, the fan will blow cooler air toward you. This creates a makeshift cooling system that can help lower your room's temperature, especially in the evenings.

One important note: when the indoor temperature climbs above 35°C, fans can stop being helpful. According to experts, at that point, you're essentially blowing hot air on yourself. So be mindful of when and how you use them.


4. Skip the Oven (and Other Heat-Generating Appliances)

Heat doesn’t just come from the sun—it comes from your own kitchen too. Ovens, cookers, even dishwashers and washing machines release heat into your home. Try to use them in the cooler hours of the day—or skip them altogether.

Stick to no-cook meals like salads or cold pasta dishes. And if you need to run the washing machine, consider doing it after sunset.


5. Cool Your Body Directly

Let’s face it—when you’re overheated, a cold drink or a damp cloth can feel like heaven. Run your wrists under cool water, use a damp towel on the back of your neck, or take a lukewarm shower before bed. Tepid water works better than freezing cold, which can cause your body to trap heat instead of letting it go.

Also, don’t underestimate the power of the right clothing. Lightweight, breathable fabrics like cotton and linen help your body regulate its own temperature. And for sleeping? A thin cotton sheet—or nothing at all—can make a big difference.


6. Head Somewhere Cooler If  You Need To



Sometimes, despite your best efforts, your home might just be too warm. If that’s the case, consider visiting a local air-conditioned space. Libraries, community centres, shopping centres—many offer a welcome escape from the heat.

Several UK cities, including London, Manchester, and Bristol, have also established public “cool spaces” where people can go during heatwaves. Even spending an hour or two in one of these places can give your body a much-needed break.


7. Prepare Your Bedroom for Better Sleep


Trying to sleep in a hot room is the worst. But you can take steps during the day to help make your bedroom cooler by bedtime.

Keep blinds and curtains closed during daylight hours. Use a fan to circulate air and open a window in the evening—safely, of course. A nursery thermometer can help you keep your room in the ideal range of 16°C to 20°C for sleeping.

At night, go minimalist with bedding. If you’re still warm, try placing your pillowcase in the freezer for a few minutes before bed. It’s a surprisingly comforting trick!
