Heat Stress is a progression of conditions as you body fights to maintain your core temperature. The most serious conditions are:
· Heat Exhaustion –Wet Clammy Skin, Normal or sub-normal body temperature
· Heat Stroke – Hot Dry Red Skin, High body temperature
When it comes to managing Heat Stress on your body, there are behavior factors that you can control:
· Physical Activity & Conditioning
· Hydration & Electrolytes
· Duration of Exposure – Time out in the sun
· Clothing – loose breathable is best
And factors that are out of your control:
· Your Age
· Medications you may be taking
· Ambient Temperature
· Humidity – water in the air
· Radiant Heat – direct sunlight
· Air Velocity – wind
The environmental factors of temperature and humidity create a perceived temperature that may be well above the measured temperature. For example:
· 90 oF at 75% RH feels like 109 oF
