Focus on heat-resilience despite the monsoon, Pg6

India is facing recurring extreme heatwaves, causing rising hospitalisations from heatstroke, dehydration, and exacerbated chronic illnesses.

• National conference ‘India 2047: Building a Climate-Resilient Future’ emphasized the need for proactive, equity-rooted public health responses.
• Current response is crisis-driven (IV fluids, hospital beds), while experts call for a preventive approach grounded in primary healthcare.
• Health effects of extreme heat are also socially unequal, with wage workers, elderly, and informal vendors facing the worst brunt.
• Call to integrate heat exposure protocols into clinical routines, especially for chronic disease patients and vulnerable groups.

Detailed Insights:

• Primary Healthcare as First Line of Defence:
  • ASHA workers, PHC staff, and wellness centre teams can act as heat safety champions—training local communities on hydration, early signs of heat stress, and protective behaviour.
  • Cities like Ahmedabad have pioneered WhatsApp alerts, door-to-door hydration drives, and mapping of vulnerable areas.
• Need for Clinical Heat Protocols:
  • Many doctors do not routinely screen for heat exposure, misdiagnosing or ignoring symptoms like heatstroke.
  • Experts recommend:
    • Pre-stocked cooling kits
    • Heat response drills
    • Post-discharge follow-up for heat-affected patients
  • Interdisciplinary Coordination Needed:
  • Urban design must ensure cool sheltering, adequate water supply, and reduced exposure at workplaces.
  • Labour policies should regulate outdoor working hours, especially during peak heat hours.
• Equity-Centred Adaptation:
  • “Stay indoors” is not a feasible option for daily-wage earners, street vendors, or homeless populations.
  • Early morning hydration stations, heat shelters, and tailored policies for low-income areas are essential.
  • Advocates call for science-policy-community integration for climate resilience.
