4 Ways to Protect Yourself from Europe's Dangerous Heatwaves 2026

The dangerous heatwaves sweeping Europe are breaking records and causing thousands of deaths, but there are proven ways to protect yourself and others. From the comfort of a friend’s air-conditioned car last weekend, I watched a dozen sweaty men on a “beer bike tour” chug booze while pedalling through Berlin, as the city broke its temperature record with 39.2C heat. Few wore hats, and their tender pink necks showed signs of sunburn. A few days later, I visited Coschen, the eastern German village that provisionally recorded the hottest temperature the country had ever seen, in a district where nearly every other voter backs a far-right party that denies basic climate science. One man who lives down the road from the station that reached the national record-breaking 41.7C high calmly told me “it was also warm” when he was young. Both of these scenes were on my mind when scientists published the first estimates of the death toll from Europe’s ferocious June heatwave, which is likely to range from several thousand to more than 20,000. Because while there are some aspects of climate breakdown that may leave you feeling powerless as an individual, I strongly feel heat should not be one of them.

Four Ways to Stay Safer During a Heatwave

There are four basic ways to cut the vast death toll from heat: stop the planet from baking, cool your immediate environment, avoid the heat, and protect vulnerable people. If you live in a rich democracy, you have power over them all. So, here’s what you can do to stay safe.

1. Cut Carbon Pollution

First, the climate. The June heatwave would have been “virtually impossible” even just a couple of decades ago, scientists say, and studies have found more than half of heat-related deaths in European cities are tied to burning fossil fuels. For the average person, cutting carbon pollution means avoiding flights, eating less meat, swapping gas boilers for heat pumps, and combustion-engine cars for electric vehicles – or bikes and buses – and simply buying less stuff. Comforting as it may be to blame billionaires and Big Oil, the way we live, move, shop and vote also has an outsized impact on how hot the planet gets.

2. Cool Your Immediate Environment

Use air conditioning wisely, install fans, and close curtains or blinds during the day. Plant shade trees or use reflective window films to reduce indoor temperatures. Even small changes, like placing a bowl of ice in front of a fan, can provide relief.

3. Avoid the Heat

Stay indoors during peak hours (10 a.m. to 4 p.m.), wear lightweight and light-colored clothing, and use hats and sunscreen when outside. Hydrate frequently with water, avoid alcohol and caffeine, and take cool showers to lower your body temperature.

4. Protect Vulnerable People

Check on elderly neighbors, infants, and those with chronic health conditions. Ensure they have access to cooling centers or air-conditioned spaces. Never leave children or pets in parked cars, even for a few minutes.
