Rising Heat and Work Capacity

August 26 , 2025 15 hrs 0 min 17 0
  • The World Health Organisation (WHO) and the World Meteorological Organisation (WMO) released a report titled Climate Change and Workplace Heat Stress.
  • The report states that work productivity drops by 2 to 3 per cent for every degree above 20 degrees Celsius.
  • Approximately half of the global population is affected by high temperatures, especially in developing countries like India.
  • Early-day temperature rise in India significantly reduces work capacity in both indoor and outdoor jobs.
  • Heat stress increases health risks such as dehydration, heatstroke, kidney dysfunction, and neurological disorders.
  • Each hourly rise in Wet Bulb Globe Temperature (WBGT) leads to further productivity loss in heat-exposed occupations.
  • Daily weather fluctuations and seasonal changes create a dual burden of reduced income and higher health costs for workers.
