Here are the National Athletic Trainers Association heat illness prevention recommendations:
- Ensure that appropriate medical coverage is available and that medical personnel are familiar with exertional heat illness prevention, recognition and management
- Conduct a thorough, physician-supervised medical screening before athletic training begins
- Adapt athletes to exercise in the heat gradually over 10 to 14 days
- Educate athletes and coaches regarding heat illness and hydration, and encourage athletes to sleep at least six to eight hours a night in a cool environment
- Develop event and practice guidelines and education materials for hot, humid weather, and check environmental conditions before and during the activity; modify activity under high-risk condition and plan rest/hydration breaks to match the environmental conditions and activity intensity
- Allow two- to three-hour rest periods at mealtimes and provide adequate supply of proper fluids to maintain hydration
- Weigh high-risk athletes before and after practice to estimate amount of lost body water; ensure a return to pre-practice weight
- Minimize the amount of equipment and clothing worn by the athlete in hot or humid conditions and minimize warm-up time when feasible
- Allow athletes to practice, or at least rest, in shaded areas
- Include the recommended and proper supplies on the field, in the locker room and at other stations
- Notify local hospital and emergency personnel before mass participation events to inform them of the event and the increased possibility of heat-related illness
