PYQ Relevance:[UPSC 2024] What is disaster resilience? How is it determined? Describe various elements of a resilience framework. Also mention the global targets of the Sendai Framework for Disaster Risk Reduction (2015- 2030). Linkage: The heat health crisis falls under the broader domain of disaster risk reduction and building resilience, especially considering extreme heat events as climate-induced disasters. It prompts discussion on defining resilience and the frameworks needed, aligning with the call for embedding heat resilience into public health systems. |
Mentor’s Comment: India is going through a serious climate-health crisis as rising temperatures and frequent heatwaves put more pressure on the already stretched public health system. At the recent national conference “India 2047: Building a Climate-Resilient Future,” experts shared not only scientific facts like wet-bulb temperatures but also the real-life struggles of informal workers. This showed how heat stress and social inequality are closely linked. The conference highlighted the need to move beyond isolated emergency care and take united, cross-sector, and fair action to build climate resilience into the way we manage public health.
Today’s editorial discusses the serious climate-health crisis as rising temperatures and frequent heatwaves. This content would help in GS Paper II ( Governance & Health Sector) and GS Paper III (Climate change impact).

Let’s learn!
Why in the News?
As extreme weather increases, we need to move from only treating emergencies to preventing problems by focusing on fair and caring public health.
Why is linking weather alerts with health systems crucial?
- Enables Timely Preventive Action: Early warning systems allow health workers to prepare and respond before heatwaves lead to medical emergencies. Eg: In Ahmedabad, heat alerts trigger distribution of hydration kits and public advisories, reducing heatstrokecases.
- Strengthens Community-Level Response: Alerts shared through ASHA workers or local networks can activate door-to-door checks, especially for the elderly and chronically ill. Eg: ASHAs sending WhatsApp messages and visiting vulnerable residents during red alerts.
- Reduces Burden on Emergency Healthcare: By preventing illness through early interventions (like avoiding midday work, increasing hydration), the pressure on hospitals and emergency services is reduced. Eg: Pre-monsoon planning with meteorological inputs helps health centers stock cooling kits and prepare treatment spaces.
What is the impact of extreme heat on India’s public health?

How does extreme heat act as a “social injustice multiplier”?
- Greater Risk to Vulnerable Populations: Outdoor workers, elderly, and slum dwellers suffer disproportionately due to poor shelter and exposure. Eg: A study by the Indian Institute of Public Health (Ahmedabad) found construction workers had a 2.5 times higher risk of heat illness compared to the general population during peak summer.
- Limited adaptive capacity: Daily wage workers, street vendors, and waste pickers cannot afford to stop working during heatwaves, making them more vulnerable to heat stress and illness. Eg: Construction workers under tin roofs suffer intense heat but have no choice but to continue working.
- Excludes the marginalised from public guidance: Advice like “stay indoors” or “avoid exertion” is often irrelevant to those who lack shelter, depend on outdoor jobs, or live in overcrowded spaces, highlighting deep systemic inequalities. Eg: A homeless person or a street vendor cannot follow “stay indoors” guidance during a red alert.
Who can act as frontline heat-safety champions?
- ASHA Workers and Primary Health Workers: Trained Accredited Social Health Activists (ASHAs) and staff at Primary Health Centres (PHCs) are well-placed to spread awareness, monitor vulnerable groups, and respond early to heat-related illnesses. Eg: An ASHA worker in a rural village sends heat alerts via WhatsApp and conducts door-to-door visits during a heatwave.
- Health and Wellness Centre Staff: Staff at Health and Wellness Centres can play a key role in educating communities, distributing hydration kits, and advising on preventive measures like staying hydrated and avoiding midday sun. Eg: A nurse at a wellness centre trains local youth on recognizing signs of heat stress and first-aid response.
What are the steps taken by the Indian Government?

What preventive steps can make India’s health system heat-resilient? (Way forward)
- Strengthening Primary Health Infrastructure: Equip primary health centres, Health & Wellness Centres, and ASHA workers with training and protocols to identify and respond to heat-related illnesses. Eg: Trained ASHA workers in rural Gujarat conduct door-to-door checks during heat alerts and share hydration tips via WhatsApp groups.
- Integrating Heat Risk into Chronic Disease Care: Clinicians should adjust medications, provide heat safety counselling, and track high-risk patients like those with heart or kidney conditions during summer. Eg: In Delhi, doctors monitor diabetic patients more closely during red alerts and advise them on avoiding midday exposure.
- Standardising Clinical Protocols for Heat Illness: Create and implement national clinical guidelines for diagnosing and treating heatstroke and heat stress, including summer drills and heat corners in hospitals. Eg: Rajasthan hospitals now stock cooling kits and have designated heat response units during summer months.
