As Delhi grapples with its first heatwave of the season, health experts are sounding alarms about the growing health risks associated with the soaring temperatures.
On Monday, the city recorded its first major heatwave, with the mercury touching a sweltering 40.2 degrees Celsius. With the Indian Meteorological Department (IMD) issuing a yellow alert, Delhiites have been urged to take extra precautions as the extreme heat intensifies over the coming days. The yellow alert, a warning to stay aware and cautious, advises people to avoid direct exposure to the sun, wear light and breathable clothing, and stay hydrated. However, experts are particularly concerned about vulnerable groups such as children, the elderly, pregnant women, and individuals with pre-existing medical conditions, including those with heart or kidney problems.
Doctors highlight that exposure to such extreme heat can lead to various health issues, ranging from mild conditions like heat rashes and muscle cramps to more severe and life-threatening ailments such as heat exhaustion and heatstroke. A senior doctor at a leading hospital in East Delhi stated that when the body’s natural cooling system is overwhelmed by extreme heat, serious conditions can emerge. “Heatstroke is the most dangerous consequence of excessive heat exposure,” he explained. “It occurs when the body’s temperature rises above 104°F, causing symptoms like confusion, rapid heartbeat, hot and dry skin, dizziness, and even seizures. The risks are particularly grave if the body’s vital organs such as the brain and heart are compromised due to reduced blood circulation caused by heat.”
While heatstroke is a medical emergency, conditions like heat exhaustion can also cause significant harm. A health professional working in a prominent community medicine department explained that heat exhaustion is typically characterised by heavy sweating, nausea, dizziness, and weakness. “If untreated, heat exhaustion can rapidly escalate into heatstroke, which can lead to unconsciousness and, in extreme cases, even death,” he added. Doctors are strongly advising people to stay well-hydrated and avoid stepping out during the peak hours of heat, typically between 11 AM and 4 PM. “If anyone starts showing signs of heat-related illness, they should be immediately moved to a cooler environment and given fluids to prevent dehydration,” one expert cautioned. Moreover, they stressed the importance of wearing lightweight, light-coloured clothing, which can help in keeping the body temperature down.
The health community has also underscored the need for preventive measures. “Staying hydrated is essential,” said a senior consultant in a prominent hospital. “Non-caffeinated fluids like water and fresh fruit juices are best. People should avoid beverages like tea, coffee, or soft drinks, which can exacerbate dehydration during peak summer months.” These preventive steps are vital to counteract the heatwave’s impact, especially in a city where temperatures can exceed 40°C in the coming days. Adding to the urgency, experts pointed out that rising temperatures could also lead to an increase in viral infections and waterborne diseases. A liver transplant specialist noted that the elderly, children, and individuals with chronic conditions like diabetes face a higher risk of developing heatstroke or dehydration. “We advise these groups to stay indoors and avoid direct sun exposure, particularly during the afternoon,” the expert advised.
The IMD’s yellow alert serves as a reminder of the importance of heat preparedness. Residents of Delhi are urged to take every precaution to protect themselves and others. While authorities work on managing the immediate risks posed by the heatwave, health experts are stressing that staying informed, taking the right precautions, and being aware of the signs of heat-related illnesses could save lives. In the coming days, Delhi is expected to experience a slight relief from the intense heat, with predictions of cloud cover and a drop in temperatures following the onset of a western disturbance. However, the immediate danger posed by the heatwave remains a critical concern for the city’s residents.
As Delhi braces for what promises to be a long, hot summer, doctors and experts are calling on the public to take the rising temperatures seriously. With extreme heat already taking its toll, the health risks associated with this heatwave are undeniable, and adhering to safety guidelines could make all the difference in avoiding severe health complications.
