Exercising safely in hot weather requires careful planning and precautions to avoid heat-related illnesses such as heat exhaustion and heat stroke. Staying adequately hydrated is crucial; drink plenty of water before, during, and after workouts, and consider sports drinks to replenish electrolytes lost through sweat. Timing your exercises to avoid peak heat hours, typically between 10 a.m. and 4 p.m., can significantly reduce the risk of overheating. Opt for early morning or late evening workouts when temperatures are cooler.
