India's vulnerability to high heat: Early onset, health risks, and inadequate action plans

India is experiencing an early onset of intense heatwaves, typically seen in May-June, now appearing in April, with temperatures exceeding 40°C in several regions. This persistent high heat, exacerbated by a lack of natural cooling and residual El Niño effects, significantly increases the risk of death from cardiovascular causes and has led to substantial work-hour losses, particularly in construction and agriculture. Experts criticize existing Heat Action Plans (HAPs) for focusing on emergency response rather than structural interventions like urban re-greening and heat-safety legislation, highlighting the urgent need for long-term funding and comprehensive public health strategies to address underlying vulnerabilities.

Key Points

  • India is experiencing early and intense heatwaves, with temperatures exceeding 40°C in April.
  • High heat is linked to increased risk of cardiovascular deaths and significant work-hour losses in key sectors.
