To stay safe during a heat wave, prioritize hydration by drinking plenty of water and using oral rehydration solutions. Avoid outdoor activities during peak heat hours, typically between 11 a.m. and 4 p.m. Wear loose, light-colored clothing and use hats or umbrellas for shade. If possible, stay in air-conditioned or well-ventilated spaces. For those without access to cooling systems, using wet towels or taking frequent showers can help regulate body temperature.
