Seasonal CRD Preparedness Tips (August)
Heat-Related Illnesses in Sports
During this season, temperatures will continue to rise and heat related illnesses will also increase. We want to help you take safety measures to secure your loved ones in sports during this season of rising temperatures.
Exercising/Practicing while hot outside
If you feel faint or weak, STOP all activity and get to a cool place
Pace activity. Start activities slow and pick up the pace gradually.
Limit outdoor activity, especially during the middle of the day when the sun is hottest
Schedule workouts and practices earlier or later in the day when the temperature is cooler.
Schedule workouts and practices earlier or later in the day when the temperature is cooler.
Don't wait until you're thirsty to drink more.
Muscle cramping may be an early sign of heat-related illness.
Monitor a teammate's condition, and have someone do the same for you.
Wear loose, lightweight, light-colored clothing.
Synthetic turf fields absorb heat, resulting in surface temperatures that are much higher.

If return to activity is difficult, consider a laboratory exercise-heat tolerance test about one month post incident.
Follow up in about 1 week for physical exam by licensed physician (MD, DO)
