Avoid midday heat. Exercise early morning or late afternoon when temperatures are cooler. Exercise in moderation and stay within target ranges. Exercise indoors on poor air quality days. Drink plenty of fluids.
Cool water is the best.
Avoid caffeinated drinks and alcohol. Wear light colored, loose fitting clothing to allow free circulation. Cotton and linen are best for absorbing perspiration. Avoid dark colors, rubberized and plastic materials, which decrease perspiration and prevent cooling of body temperature. Keep rooms cool with air conditioning or fans.
