Whether it’s generated in an indoor setting such as a non-air-conditioned warehouse or foundry or in outdoor worksites such as construction sites or farms, too much heat can be a killer.
- Three progressive stages of heat illness are heat cramps, heat exhaustion and heat stroke. Heat cramps, the first sign of heat illness, are muscle cramps. Heat exhaustion is a state of being dizzy, weak and nauseated because of dehydration and loss of body minerals through sweating. Heat exhaustion occurs when the body can no longer cool itself. This condition can quickly turn fatal as body temperature spikes.
- One factor that can bring on heat illness more quickly is high humidity. Humidity reduces the rate at which sweat evaporates from the body, keeping body heat on the skin and thereby causing the body’s temperature to rise.
- It takes the human body between seven and 10 days to adapt to working in hot weather conditions. (MedicineNet.com)
- Five symptoms of heat stroke are red, hot, dry skin; high body temperature; confusion; fainting; and convulsions.
