With rising temperatures in India, heatwaves pose a significant public health threat, particularly for vulnerable populations such as children, the elderly, and outdoor workers. Experts, including Dr. Snehal Kohale and Dr. Ravi Malik, emphasize the potential of wearable technology, such as smartwatches and fitness bands, to monitor vital health metrics like core body temperature and hydration levels. These devices can provide real-time alerts, prompting users to hydrate or seek cooler environments before symptoms of heat stress worsen. However, experts caution that wearables should not replace traditional medical assessments and that their accuracy can vary. Basic preventive measures, such as staying hydrated and avoiding peak sun exposure, remain crucial. As technology evolves, wearables may play an increasingly important role in managing heat-related health risks, potentially saving lives during extreme heat events.
