Safe Running in Hot Weather

Running in sun, heat, and humidity requires that you take special precautions. Minimizing fluid loss and heat gain is essential. Some tips to remember:

• Drink water whenever possible. Water is the vital ingredient in the prevention of heat injury. Thirst is not a reliable indicator to warn a runner of fluid loss. Your body loses a considerable amount of fluid before you feel thirsty.
• Avoid caffeinated and alcoholic beverages which have a diuretic effect.
• Wear white clothing to reflect the sun's rays. Avoid dark clothing which absorbs heat.
• Run during the coolest part of the day.
• Choose a shady course.
• Run where you have access to water.
• Splash yourself with water to aid in cooling your body.
• Remove wet clothing which hampers evaporation.
• Be aware that increased humidity blocks body cooling via evaporation of sweat. Avoid running when relative humidity exceeds 90%.
• Avoid running long distances alone.
• Know the warning signals of heat-related problems:
  1. Do not try to run through heat cramps: stop, rest, drink water;
  2. Signs of heat exhaustion are faintness, weakness, and mental confusion: if symptoms develop, stop, find shade, drink water;
  3. Signs of heatstroke are decreased sweating and hot, dry skin: stop all activity and find a means of cooling your body as rapidly as possible, remove clothing and rub body with ice and alcohol, seek medical treatment.
• Consider another form of exercise when adverse weather conditions make running dangerous.
