Prevention and planning

Screen for significant preexisting medical conditions.

Recognize that being overweight is associated with greater risk of heat illness.

Ensure euhydration before activity.

Ensure ongoing rehydration with a “drink to thirst” approach sufficient to prevent greater than 2% loss of body weight.

Use the wet-bulb globe temperature index to assess heat risk.
