Delhi faced an unusually high temperature, reaching 7.2 degrees above the established norms for the season. The rise in temperature follows the trend observed in 2025, which recorded the eighth warmest year since the India Meteorological Department (IMD) began keeping records in 1901.

India experienced its hottest February in 124 years last year, with average temperatures surpassing 22 degrees Celsius. Globally, the past few years have shown similar patterns, with 2024 being documented as the hottest year on record.

Extreme heat has become a constant threat to human health rather than an isolated occurrence. While various local factors contribute to such temperature increases, global warming remains a primary driver, bringing about frequent and severe heatwaves.

Heat’s Effects on Physical and Mental Well-Being

Prolonged exposure to high temperatures hampers the body’s ability to regulate its internal temperature through sweating. This inability raises the risks of developing heat-related illnesses, such as cramps, exhaustion, and potentially life-threatening heatstroke.

Dr Rahul Mathur from CK Birla Hospitals in Jaipur highlights that heat-related ailments can escalate quickly, with heatstroke presenting symptoms that require immediate medical attention. Reports suggest that the number of individuals susceptible to such conditions is increasing due to rising temperatures.

Moreover, the World Health Organization has indicated that heat stress could exacerbate existing health issues, including those related to cardiovascular health, mental health, and asthma, complicating the overall health landscape for a large portion of India’s population.

Impact of Heat on Mental Health

Experts assert that prolonged exposure to extreme heat can significantly undermine mental health. High temperatures can disrupt sleep and increase discomfort, leading to stress and irritability. Dr Gorav Gupta, CEO and Senior Psychiatrist at Tulasi Healthcare in Gurugram, notes that such conditions often lead to lowered mood and difficulty in concentration.

Dr Munia Bhattacharya, a Senior Consultant in Clinical Psychology at Marengo Asia Hospitals, affirms that the physiological stress induced by excessive heat can elevate anxiety and trigger mood swings. This prolonged exposure can diminish a person’s resilience to stress, making everyday challenges feel insurmountable.

Dehydration and fatigue, particularly related to extreme heat, can also impair cognitive functions, making it increasingly difficult for individuals, especially those with pre-existing mental health conditions, to cope.

Healthcare Response and Preventive Measures

As heat strain becomes more prevalent, the healthcare community stresses the importance of recognising symptoms related to mental stress in high temperatures. Increased irritability, confusion, and withdrawal from social activity can indicate rising mental distress, which should not be overlooked.

Dr Amit Kumar Malik, Director at Medanta Hospital, recommends that individuals with existing cardiovascular risks remain vigilant for symptoms such as unusual fatigue or difficulty breathing in hot conditions. Similarly, maintaining hydration and awareness about heat-related health issues is vital.

Several cities in India have introduced heat action plans; however, experts argue that these efforts often lack adequate implementation and legal support. Indu Murthy from CSTEP points out that the current measures need to address local geographical and climatic factors more comprehensively to be effective.
