Don't Lose Your Cool. Manage Work Place and Athlete Heat Stress.

Sometimes we only use the air temperature as a measure of how comfortable we will feel when working or playing outside. But when the days get longer and the sun becomes stronger we need to take into account a lot more than air temperature.

Heat-induced illnesses, such as heat exhaustion and heat stroke occur when your body can't keep itself cool. The evaporation of sweat is slowed on hot and humid days causing your body temperature to rise and become ill.

Symptoms of Heat Exhaustion and Heat Stroke

Dizziness, Headache, Weakness, Nausea
Rapid Heartbeat, Cramps, Chest Pain
Labored Breathing, Lack of Sweating
Mood changes such as irritability or confusion
High fever (104°F and Higher) for Heat Stroke Victims

Preventing Heat Stress

Know signs/symptoms of heat-related illnesses; monitor yourself and your coworkers
Block out direct sun or other heat sources
Rest regularly
Drink lots of water; about 1 cup every 15 minutes
Wear lightweight, light-colored, loose-fitting clothes
Avoid alcohol, caffeinated drinks, or heavy meals

And most importantly….Monitor the conditions you are in with a Heat Stress Meter
These meters measure how hot it REALLY feels outside when humidity is combined with temperature, air movement, and radiant heat.
