According to the German Weather Service (DWD), a heatwave is characterized by a period of several days with unusually high thermal stress. It is an extreme event that can damage human health, ecosystems and infrastructure.

Periods of heat pose a serious risk to human health. Prolonged periods of heat worsen well-being and health. The quality of sleep deteriorates, particularly due to the persistent heat at night, and the body is unable to recover properly. The circulatory system is under particular strain. Sweating causes the human body to lose fluids and salts. This can result in dizziness, unconsciousness or even life-threatening heatstroke.

Heat warnings are issued when a high heat load is forecast and sufficient cooling of the interior at night is no longer guaranteed.

The German Weather Service (DWD) uses its heat warning system to warn of impending hot days. Further information on the heat warning system and the "WarnWetter app" can be found at: https://www.dwd.de (opens in a new tab)

When it's hot, opt for light foods such as salads, soups and fruit. Provide your body with important minerals. Avoid hearty food.

On hot days, the need for fluids is significantly increased. Therefore, drink regularly and sufficiently - at least two to four liters. Water, fruit spritzers and slightly chilled teas are suitable. Avoid alcohol and highly sweetened drinks. The amount to drink varies according to body size and weight.

There are around 60 "refill stations" in Wiesbaden, where you can fill tap water into drinking vessels you have brought with you free of charge. You can find the refill stations in the "Map of cool places".

Fabrics such as thin cotton, linen, silk and viscose are breathable and ideal for wearing on hot days. Preferably choose light-colored, light and loose clothing.

Headgear, sunglasses with UV protection and sunscreen for the skin protect against direct sunlight. Make sure you drink enough fluids. Find cool places (e.g. shady spots in parks) near you. Important: Avoid the heat and do not go into direct sunlight.

You can find a "map of cool places" at Geoportal Wiesbaden (opens in a new tab).

The map shows places in the Wiesbaden city area that offer cooling on hot days, such as green spaces, fountains, streams and bodies of water, playgrounds with and without water features and similar.

Avoid direct sunlight. Darken your home. Roller shutters are best for this, but curtains or drapes are also suitable.

Ventilate early in the morning or late in the evening if possible. If possible, make sure it is cooler outside than in the building.

Take a cool shower or a cool bath. Cold arm and foot baths have a relieving effect. Cool down by placing a cool cloth on your forehead, for example.

You should try to keep the room as cool as possible. Use a light linen sheet, a comforter cover without a blanket or a cotton sheet as a blanket.

Exercise as early in the morning or late in the evening as possible. Take frequent breaks and look for a shady or cool place. Make up for the additional fluid loss with suitable drinks. Wear breathable functional clothing and headgear. Shower as lukewarm as possible. Cold water puts additional strain on your circulation.

If you are taking medication, please consult your doctor before a period of heat. Store medication according to the instructions and make sure it is stored at the correct temperature.

If you experience symptoms such as nausea, dizziness, headaches or a feeling of exhaustion, you should contact your family doctor's practice or the medical on-call service on 116117.

If you experience symptoms such as clouding of consciousness, unconsciousness, new onset of confusion, repeated vomiting, body temperature above 39°C, you should call 112.

Take care of your fellow human beings and help in times of need. Further information can be found on the homepage of the Federal Institute of Public Health (BIÖG) (opens in a new tab).
