India's Heatwaves Arrive Earlier with Rising Health Risks for Vulnerable Groups

Recent data indicate that heatwaves in India are arriving earlier, lasting longer, and affecting broader areas, with rising night-time temperatures reducing relief. Health risks from extreme heat are significant, especially for older adults and children, who face severe activity limitations—up to 900 hours annually—due to heat stress. Experts advise hydration and avoiding peak heat hours to mitigate heat-related illnesses. These trends reflect broader global warming impacts on human livability and health.
