Most heat-related health problems can be prevented. The following are a few basic precautions that will help reduce the risk.

The day before strenuous activity drink more fluid than needed. Thirst poorly indicates the need for water.

Drink plenty of water during the activity. Stop often at least every half hour and drink between 5-12 ounces an hour. Do not drink alcohol or beverages with caffeine.

Alternate work and rest. If possible heavy work should be scheduled during the cooler parts of the day.

Acclimation to heat through short exposures leading up to longer exposures. A good rule of thumb of acclimation is a worker should start at 50% of the normal workload and work up to 100% on the fifth day.

Wear a wide brimmed hat.
