How to stay cool in dangerous heat

Denmark is bracing for dangerous heat, with temperatures above 30°C expected across much of the country from Friday to Sunday, according to the Danish Meteorological Institute (DMI). A Copenhagen-based doctor offers practical advice to avoid overheating.

Rest in the shade. Physical exertion generates body heat, so avoid mowing the lawn, running, or playing with children, says Charlotte Bech, a general practitioner near Nørreport. Lying still in a shaded, breezy spot reduces metabolic heat production.

Eat salty foods and drink rehydration solutions. Sweating depletes fluids and electrolytes, so salted soups like gazpacho or avocado soup help, Bech says. A salted tomato or cucumber works if cooking is too much effort. Plain water lacks the necessary minerals, so mineral water, juice, or watermelon are better for hydration.

Avoid alcohol, coffee, and tea. These are diuretics and increase fluid loss. Bech warns that alcohol is particularly dangerous in extreme heat, as it impairs judgment and the ability to recognize the body’s warning signals.

Cool the neck and wrists. Blood vessels are closest to the skin in these areas, so chilling them with a damp cloth or ice pack quickly lowers core temperature, Bech explains.

Use cooling scents. The doctor adds that inhaling eucalyptus or mint essential oils can create a sensation of coolness, enhancing comfort in the heat.
