Protecting Yourself from Heat Stress

 

Heat Illness

Exposure to heat can cause illness and death. The most serious heat illness is heat stroke. Other heat illnesses, such as heat exhaustion, heat cramps and heat rash, should also be avoided. If you are older (60+), in poor health, have a heart condition or are taking certain medications (e.g. some antidepressants, beta blockers, diuretics) you may be more susceptible to heat stress.

 

Other Risk Factors for Heat Illness

• High temperature and humidity, direct sun exposure, no breeze or wind

• Low liquid intake, consuming caffeine/alcohol (diuretics) or certain medications

• Overweight, pregnancy, poor health

• Heavy physical labor

• Waterproof clothing

• No recent exposure to hot workplace

 

Symptoms of Heat Exhaustion

• Headache, dizziness, or fainting

• Weakness, wet skin, profuse sweating

• Irritability, confusion, dizziness, pale or flushed skin

• Thirst, nausea, or vomiting

 

Symptoms of Heat Stroke

• May be confused, unable to think clearly, pass out, collapse, or have seizures (fits)

To Prevent Heat Illness, You Should

• Drink plenty of cool water. At least one pint of water per hour is needed

• Stay inside, in air conditioning if possible

• Block out direct sun or other heat sources

• Wear lightweight, light colored, loose-fitting clothes
