Heat Index Guidelines

Heat Index under 95°

All sports:

 Provide ample amounts of water. This means water should always be available and athletes should take in as much water as they desire.

 Optional water breaks every 30 minutes for 10 minutes duration.

 Ice-down towels for cooling

 Watch/monitor athletes carefully for necessary action

 Provide cold tubs or child pool for water or ice baths

 If on artificial turf (not sure how many this would impact) have water source to cool down turf

 Stay away from energy drinks--water is the best for hydration and recovery

 Take breaks in shaded areas when possible or in air conditioned buildings or vehicles

The Wet Bulb Globe Temperature chart is a great tool to use. It is more accurate than the heat index.
