Doctor Lists Heatwave's Highest Risk Groups: Elderly, Children, Chronic Patients
Elderly, kids, laborers, patients face highest heatwave dangers; hydration critical.
As severe heatwave conditions grip several parts of the country, doctors are warning that certain groups face significantly higher health risks, especially during early-season temperature spikes when the body has not yet adapted to extreme heat.
According to medical experts, early heatwaves can have a sudden and severe impact on the human body. With temperatures rising rapidly across northwest and central India, the lack of acclimatisation increases vulnerability to heat-related illnesses such as dehydration, heat exhaustion, and heatstroke.
Doctors identify the elderly and young children as among the most vulnerable populations. Age-related factors, such as reduced ability to regulate body temperature in older adults and underdeveloped thermoregulation in infants, make these groups particularly susceptible to extreme heat. People with chronic illnesses—including heart disease, diabetes, and respiratory conditions—also face elevated risks, as heat places additional strain on vital organs.

Outdoor workers and individuals exposed to direct sunlight for prolonged periods are another high-risk category. Labourers, delivery personnel, and others working in high-temperature environments are more likely to experience dehydration and heatstroke due to continuous exposure and physical exertion. Additionally, people on certain medications or those with limited access to cooling and hydration are at increased risk during prolonged heatwaves.
Health experts emphasise that extreme heat acts as a “multi-organ stressor,” affecting the heart, kidneys, brain, and metabolic systems. The body works harder to maintain its core temperature, increasing cardiovascular strain and the likelihood of complications, particularly in those already vulnerable.
To stay safe, doctors recommend staying hydrated, avoiding outdoor activity during peak afternoon hours, wearing light and breathable clothing, and seeking cool or air-conditioned environments whenever possible. Recognising early symptoms—such as dizziness, fatigue, rapid heartbeat, and high body temperature—is critical, as timely intervention can prevent life-threatening complications during extreme heat events.
