ČHMÚ warning - Extreme Heat Stress

Extreme heat stress expected. High risk of overheating and dehydration. Heavy load on the healthcare system and social services (especially care for the elderly and chronically ill). Significant decline in worker performance with a marked increase in the risk of occupational accidents or illness, particularly for outdoor jobs or work in stuffy enclosed environments.

Avoid exposure to the sun or overheated urban areas, strictly maintain hydration with increased intake of non-alcoholic beverages (including mineral replenishment), avoid higher physical/mental loads, ventilate only during cooler parts of the day (usually early morning). In case of health problems, seek medical help without delay. Do not leave children or animals in parked vehicles. Set air conditioning in rooms or vehicles so that the body is not exposed to excessive thermal shock when moving in or out; the difference between indoor and outdoor temperatures should not exceed 5 to 8 °C.
