As global temperatures rise due to climate change, heavy laborers are exposed to heat stress and dehydration more regularly and more severely, likely putting them at greater risk of CKDu.
Occupational risks related to workload and heat stress include heat stroke, heat exhaustion, and rhabdomyolysis.
HEAT STROKE is the most serious heat-related illness. It occurs when the body can no longer control its temperature. Symptoms may include confusion; fainting; seizures; very high body temperature; hot, dry skin; or profuse sweating. Heat stroke can be fatal.
HEAT EXHAUSTION is also serious. Symptoms may include: headache, nausea, dizziness, weakness, thirst, and heavy sweating.
RHABDOMYOLYSIS is a condition where heat stress and prolonged physical exertion causes the breakdown of muscle. This causes proteins to be released into the bloodstream and can lead to weakness, muscle cramps, irregular heart rhythms and seizures, and kidney damage.
