Swedish heatwave prompts expert advice on staying cool

Sweden is facing a significant heatwave this weekend, prompting the Swedish Meteorological and Hydrological Institute (SMHI) to issue orange and yellow warnings for high temperatures in multiple regions. The warnings primarily target at-risk groups, including the elderly, with temperatures expected to exceed 33 degrees Celsius for several consecutive days in parts of Blekinge, Kalmar, and Kronoberg counties.

Geriatric professor Sölve Elmståhl stresses the importance of hydration, especially for older adults whose thirst sensation can decline with age. He recommends keeping at least two liters of fluids refrigerated and consuming a liter in the morning and another in the afternoon, or more if temperatures reach 30 degrees Celsius in the shade. Elmståhl also suggests a simple homemade electrolyte drink: one liter of water, six teaspoons of sugar, and half a teaspoon of salt.

High humidity exacerbates the heat's impact by hindering sweat evaporation. In such conditions, seeking cool indoor environments with fans or using wet towels can help. Elmståhl notes that some elderly individuals may not recognize the signs of overheating, potentially developing confusion. Therefore, relatives should remain vigilant.

For cooling down, Elmståhl suggests showers with lukewarm water (15-18 degrees Celsius) rather than ice-cold water. He explains that cold water constricts blood vessels, while lukewarm water allows blood to circulate to the skin for better cooling. Activities like gardening and long walks should be avoided during the hottest parts of the day. The most crucial advice, he reiterates, is to simply avoid the sun and intense heat exposure.
