Rising temperatures in India are transforming heatwaves from seasonal nuisances into serious public health emergencies. Dr. Tushar Goyal, a consultant physician at Kailash Hospital, highlights that both vulnerable groups and otherwise healthy individuals are increasingly affected by dehydration, heat exhaustion, and heatstroke. Urban areas, characterized by dense infrastructure and limited greenery, further amplify these risks. The combination of heat-retaining surfaces and inadequate hydration can disrupt normal bodily functions, leading to severe health issues. Beyond physical health, heatwaves also impact mental well-being, causing sleep disturbances and fatigue that hinder productivity. To combat these risks, Dr. Goyal emphasizes the importance of staying hydrated, avoiding outdoor activities during peak heat, and recognizing early warning signs of heat-related illnesses. As heatwaves continue to pose significant health threats, collective awareness and proactive measures are essential to mitigate their impact.
