Southeast Europe faces record heat wave with health warnings and cooling measures

A severe heat wave is sweeping across Southeast Europe, with temperatures reaching up to 39 °C in parts of Croatia, Bosnia‑Herzegovina, Serbia and neighboring countries. Meteorological services have issued red alerts for much of the region and yellow alerts for surrounding areas. Health officials warn that extreme heat can cause dehydration, heat exhaustion and heat stroke, especially among the elderly, children, pregnant women and people with chronic cardiovascular, respiratory or metabolic conditions.

Authorities recommend drinking plenty of water and electrolyte‑rich drinks, avoiding direct sun between 11:00 a.m. and 5:00 p.m., wearing light, loose clothing, and staying in shaded or air‑conditioned spaces. Public swimming pools, lakes and water parks are being promoted as cooling spots; Zagreb will offer free entry to municipal pools and climate‑controlled museums this weekend, and several Croatian towns report high visitor numbers at local lakes. Similar measures are in place in Serbia and Bosnia‑Herzegovina, where municipal pools have reopened and free water fountains are being highlighted.

Additional health advice includes limiting heavy meals, alcohol and caffeine, and being cautious with food that can develop toxins when reheated, such as rice and spinach. Experts also stress the importance of proper indoor ventilation and moderate thermostat settings to avoid large temperature swings that can strain the cardiovascular system.
