Things are heating up weather wise, but if you still want to keep your workout outside (say while doing my beach body beach workout) use these tips from the American Council on Exercise on burning calories without burning up in the heat:
- Hydration: Fluid replenishment before, during and after exercise is essential to avoid progressive dehydration. Always consume more fluids than you think you need before and after exercise, and strive to drink six to eight ounces of fluid every 15 to 20 minutes during exercise.
- Exercise Intensity: You should probably reduce the intensity of your workout, particularly the first few times you are exposed to higher temperatures.
- Temperature: Use the heat stress index table (at the right) to determine the risk of exercising at various combinations of temperature and humidity. While a 90° F outdoor temp is relatively safe at 10 percent humidity, the heat stress of 90° F at 50 percent humidity is the equivalent of 96° F. When the heat stress index rises above 90° F, you may want to consider postponing your exercise session until later in the day. Or, plan ahead, and beat the day's heat by working out early in the morning.
- Fitness: Physical training and heat acclimation can increase your blood volume, helping to regulate body temperature more effectively. Interestingly, the acclimatization process can be completed in 7 to 14 days of repeated heat exposure. However, you must always continue to drink fluids before, during and after exercise.
- Clothing: Wear minimal clothing to provide greater skin surface area for heat dissipation. Your clothing should be lightweight, loose fitting, light colored to reflect the sun's rays, and of a material that absorbs water, such as cotton.
- Rest: Know when to say 'no' to exercise. Using common sense is your best bet for preventing heat stress when Mother Nature turns up the heat.
