Heat Stress
Definition
Heat stress occurs when the body cannot cool itself enough to maintain a healthy temperature, often due to prolonged exposure to high temperatures or physical exertion in the heat.
Scientific / Technical Definition
Heat stress is a physiological condition in which the body undergoes molecular and cellular stress responses due to excessive heat exposure. It disrupts cellular homeostasis, causing an increased risk of heat-related illnesses like heat exhaustion and heat stroke. During heat stress, thermoregulatory mechanisms such as sweating and increased blood flow to the skin are activated to dissipate heat, but these can be insufficient under extreme conditions.
Benefits
- Heightened awareness of heat stress can help in preventing heat-related illnesses.
- Understanding how to manage heat stress improves hydration and cooling strategies, protecting overall health.
Examples
- Wearing appropriate clothing and staying hydrated during outdoor activities in hot weather.
- Taking breaks in shaded or air-conditioned areas when working outdoors.
Additional Information
- Known issues: Heat stress can lead to dehydration, heat cramps, heat exhaustion, or even life-threatening heat stroke if not properly managed.
