Working in Hot Conditions, Indoors or Outdoors, Creates Health Risks
- Heat cramps occur when the body loses too much salt from heavy exertion in heat.
- Heat exhaustion occurs when the body can’t replace fluids and/or salt lost in sweating.
- Perspiration in heat is important, because it cools the body as it evaporates.
- Heat stroke occurs when the body no longer sweats and holds so much heat that body temperature reaches dangerous levels. Heat stroke is a medical emergency and can lead to delirium, convulsions, unconsciousness, or even death.
Factors that can increase the risk of these types of heat stress include:
- Physical exertion
- Being unaccustomed to working in heat
- Wearing protective clothing that traps body heat
- Age Older people may have less body water and lower sweat gland efficiency.)
- Being overweight, which makes you use more energy to perform tasks
- Medications that can interfere with normal body reactions to heat
