Noida, Apr 28 (APAC Media): Delhi continues to reel under intense heatwave conditions, with unusually high nighttime temperatures compounding the discomfort and posing serious health risks.
The India Meteorological Department (IMD) has reported that minimum temperatures in the capital remain significantly above normal, denying residents the much-needed respite typically expected after sunset.
“Persistently high nighttime temperatures are particularly dangerous because the body does not get the chance to recover from daytime heat. This continuous exposure can increase cardiovascular strain, disrupt sleep, and elevate the risk of heat-related illnesses,” said a senior public health expert.

Doctors warn that such conditions increase strain on the cardiovascular system. As the body struggles to regulate temperature, the heart works harder, potentially raising the risk of heart-related complications, including hypertension, heart attacks, and strokes.
The lack of cooling also disrupts sleep patterns, leading to fatigue, irritability, and reduced concentration levels during the day.
“People often underestimate the impact of hot nights, but they can be just as harmful as extreme daytime heat. Vulnerable groups, including the elderly and those with chronic conditions, need to be especially cautious,” the expert added.
Sleep deprivation caused by excessive heat can further aggravate mental health issues such as anxiety and depression, experts noted.
In addition, the cumulative effect of heat exposure over consecutive days without adequate nighttime relief raises the risk of heat-related illnesses like heat exhaustion and heatstroke.
Medical professionals also point out that hot nights can worsen chronic illnesses such as diabetes, kidney disorders, and respiratory conditions. Continuous sweating during sleep may lead to dehydration, placing additional stress on the body and affecting overall health.
Authorities have advised residents to take preventive measures, including staying well-hydrated, using cooling devices, and avoiding heavy meals or strenuous activities late in the evening. As the heatwave shows little sign of abating, experts stress the need for increased awareness and caution to protect public health.
