Hungary warns of water‑poisoning risk during heatwave, urges careful hydration

Health officials in Hungary caution that the prolonged heatwave and increased fluid intake can lead to water intoxication. Symptoms such as dizziness, headache, nausea, vomiting, confusion, muscle cramps and changes in urine color may indicate the condition, which in severe cases can cause brain swelling, coma or death. The advice emphasizes drinking steadily throughout the day, supplementing water with soups, fruits, isotonic drinks, and avoiding excessive alcohol or caffeine. Staying in shaded or air‑conditioned areas, using sunscreen, and taking cool showers are also recommended.

At the same time, the national water utility stresses responsible water use during the heat. While Hungary’s water reserves remain adequate, utilities warn that pipe breaks or power outages could disrupt supply, leading to temporary shortages. The public is urged to conserve tap water by using rainwater for irrigation, limiting irrigation with drinking water, and avoiding washing streets with potable water. These measures aim to preserve the water resource for the coming months while ensuring safe hydration for the population.
