What is a Heat-Related Illness?
A heat-related illness happens when the body can’t cool itself properly. Normally, sweating helps regulate our body temperature. But in extreme heat or with dehydration, that system fails. The result? A range of conditions from minor discomfort to life-threatening emergencies.
Who is Most at Risk?
While heat can affect anyone, certain groups are more vulnerable:
-
Infants and toddlers
-
Elderly individuals
-
People with chronic illnesses like diabetes or heart disease
-
Outdoor workers
-
Athletes
-
Pet owners (yes, animals suffer too!)
Common Types of Heat Illnesses
Heat Cramps
Painful muscle spasms, usually in the legs or abdomen, caused by dehydration and loss of electrolytes.
Heat Exhaustion
Characterized by heavy sweating, weakness, dizziness, nausea, and fainting. It’s a big warning sign and needs attention.
Heat Stroke
This is the most dangerous—body temperature spikes above 104°F (40°C), and the person may become unconscious. It’s a medical emergency.
Heat Rash
Tiny red bumps, itching, and irritation due to excessive sweating—usually on the neck, chest, or back.
Dehydration
Not drinking enough fluids? Your body will start shutting down essential processes. It’s the root of many heat illnesses.
