How does our body work to cool itself?
Conduction- Heat loss through direct contact with a cool object
Convection- the dissipation of heat when cool air passes over exposed skin
Radiation-the release of heat from the body into the environment
Evaporation- through perspirationSlide5
The Heat Index
Air Temperature + Relative Humidity
The human body normally cools itself by
perspiring and then evaporating
Relative Humidity reduces the evaporation rate
High humidity reduces the body’s ability to get rid of excess heat Slide6Slide7
Factors Leading to heat Related Emergencies
High temperatures and high humidity
Direct sun or heat
Limited air movement
Physical exertion
Poor physical condition
Protective clothing
Some medications-
beta blockers, calcium channel blockers, diuretics, laxatives
Inadequate tolerance for increased heatSlide8
Heat Stress
