Heatwave safety: Guidelines for preventing heatstroke and exercising safely

As rising temperatures and heatwaves become more frequent, health guidelines emphasize precautions to prevent heat exhaustion and heatstroke. Key recommendations include reducing heavy physical activity, especially in high humidity, and staying in cool, shaded environments using air conditioning or fans.

To manage body temperature, it is advised to wear light, breathable, and light-colored clothing such as cotton or linen, and to use hats and sunglasses when outdoors. Hydration is critical; individuals should drink plenty of water and fruit juices, though those with specific medical conditions like heart, kidney, or liver issues should consult a doctor before significantly increasing fluid intake.

For those maintaining physical activity, experts suggest adjusting routines by reducing intensity and duration. Exercising during cooler parts of the day, such as early morning or late evening, is recommended to avoid peak heat. High humidity can hinder sweat evaporation, making it harder for the body to cool down, which increases cardiovascular strain and fatigue.
