This summer, the thermometer is expected to panic throughout the WHO European Region. It is important that we are all aware of the risks associated with high heat and know how to maintain our health so that we can enjoy the sporting events and festivals that will take place over the coming months.
Heat stress is the leading cause of climate-related mortality in the Region. Over the last 20 years, heat-related mortality has increased by 30%, and it is estimated that it has increased in most countries in the Region that monitor this phenomenon.
Extreme temperatures can also worsen chronic diseases, including cardiovascular, respiratory and cerebrovascular diseases, as well as conditions related to diabetes. Additionally, extreme heat can place an additional burden on pregnant women. However, the adverse health effects of heat can be largely avoided through good public health practices.
WHO #KeepHead Campaign
WHO/Europe is launching its annual #KeepYourHead campaign to raise awareness of the dangers of extreme heat and provide simple advice so everyone can protect themselves.
- Avoid the heat: Refrain from going out and doing strenuous activities during the hottest times of the day. If you’re vulnerable to heat, take advantage of opportunities like senior hours in stores when it’s cooler in the morning and evening. Stay in the shade, do not leave children or pets in a parked vehicle, and if necessary and possible, spend 2 to 3 hours a day in a cool place.
- Keep your interior fresh: take advantage of the mildness of the night to refresh your interior. During the day, reduce the heat load in your apartment, house or hotel room by closing blinds or shutters, and turning off electrical appliances, where possible.
- Hydrate and cool your body: wear light, loose clothing, sleep on thin sheets, take cool showers or baths, and drink water regularly while avoiding sugary, alcoholic, or caffeinated beverages, due to their dehydrating effects on the body.
It is important to take care of yourself and check on isolated family members, friends and neighbors who are well. Vulnerable people may need help during hot weather. If you know people around you who are at risk, help them find good advice and support.
Protect yourself from the heat when you’re on the move
This year, 3 major international sporting events will be organized in the Region: the 2024 UEFA European Football Championship (from June 14 to July 14 in Germany) and the 2024 Summer Olympic Games (from July 26 to 11 August), immediately followed by the Paralympic Games (August 28 to September 8), both of which will be held in Paris (France).
In addition to all the usual events and festivals of the summer months, these events will attract even larger crowds. We can all protect ourselves by following the simple advice from #KeepYourHead, and keeping a few things in mind when traveling.
- When you leave for the day, take a refillable water bottle and drink frequently throughout the day, even if you don’t feel thirsty.
- On hot days, eat light meals. Instead of large plates, opt for several smaller portions throughout the day, choosing fresh foods (fruits, vegetables, salads, low-fat soups, dairy products, etc.).
- Look for shaded areas and protect yourself from the sun with a hat, parasol, sunglasses and sunscreen (SPF 30 at least).
- Dress lightly in loose, light-colored clothing that reflects sunlight rather than absorbing it.
- Plan your day by scheduling events, visits to tourist attractions and excursions for the morning or evening, when it is cooler.
- Check that your medications can withstand heat. Carefully follow the instructions for their storage.
- Know how to recognize the symptoms of heatstroke (dizziness, nausea, confusion, excessive sweating, etc.). If you experience these symptoms, seek medical attention immediately.
A global challenge today
When it comes to the consequences of climate change, the Region is no exception. It is the WHO Region warming the fastest, with temperatures rising about twice as fast as the global average. The 3 hottest years have been recorded there since 2020, and the 10 hottest years since 2007.
Due to climate change, heat waves are a growing concern today. Over the past 30 years, the time window where physical exercise could induce heat stress has expanded beyond the hottest times of the day. This development could lead to a reduction in physical activity in general, which in turn would result in a risk of contracting non-communicable diseases.
The frequency, intensity and duration of heat waves, as well as other extreme weather events, are expected to increase in the coming decades. It is therefore all the more important that individuals and communities understand the risks and how to prepare for them, and that health systems and society adapt to the changing climate.
Together, we can ensure that heat-related illnesses do not cast a shadow on the beautiful game of football and the spirit of the Olympic Games. By staying informed and taking certain precautions, we can all enjoy summer safely, whether that’s cheering on our favorite teams, listening to our favorite bands, or exploring new destinations.
