As extreme heatwaves become more frequent, medical experts warn of their detrimental effects on mental health. High temperatures can lead to increased anxiety, irritability, and aggressive behavior due to physiological stress on the body. Dr. Pavitra Shankar from Aakash Healthcare highlights that prolonged heat exposure disrupts the body's cooling mechanisms, resulting in emotional exhaustion and heightened stress levels. The 'heat-aggression' hypothesis suggests a direct correlation between rising temperatures and increased violent crimes, with studies indicating a 3-5% rise in assaults during hotter periods. Poor sleep quality exacerbates these issues, as high nighttime temperatures interfere with the body's natural cooling process. Vulnerable groups, including children, older adults, and outdoor workers, face heightened risks during heatwaves. Experts recommend preventive measures, such as staying hydrated and maintaining good indoor ventilation, to mitigate the psychological effects of extreme heat. They emphasize the need for public awareness and mental health support in heat action plans, recognizing that heatwaves are not merely weather-related issues but significant mental health concerns.
