Getting to Know Heat Index

High humidity makes heat more dangerous because it slows the evaporation of perspiration-the body's natural cooler. That caused outdoor exercise more dangerous even for those in good shape.

Key rules for coping with heat are to drink plenty of water to avoid dehydration and to slow down and cool off. Overheating can cause serious, even life-threatening conditions such as heat stroke.

The Heat Index is to show how hot a particular combination of heat and humidity feels. The Heat Index in the Hydra-AlertTMis a report of the latest weather conditions based on the current temperature and the relative humidity. You can refer to the following Heat Index Chart to know the apparent temperature and to avoid getting into danger during exercise.
