FACTS

1. Dehydration Onset: Working in high heat drains body fluids quickly; dehydration reduces sweating ability, raises core temperature, and accelerates heat illness.
2. Core Temperature Rise: When the body absorbs more heat than it can release, internal temperature climbs fast, leading to heat exhaustion and potentially deadly heat stroke.
3. High Humidity Stress: Humidity slows sweat evaporation, preventing cooling and making temperatures feel significantly hotter than they are.
4. Heat Cramps Warning: Painful muscle cramps in legs, arms, or abdomen signal electrolyte imbalance and early heat stress requiring immediate rest.
5. Reduced Cognitive Function: Heat exposure impairs judgment, balance, and reaction time—raising the risk […]
