In India, increasing humidity levels are making heatwaves more lethal, as indicated by the wet-bulb temperature, which measures the combined effect of heat and humidity. This phenomenon complicates the body's ability to cool itself, posing serious health risks, particularly for vulnerable individuals.
- 01Wet-bulb temperature indicates how effectively the human body can cool itself through sweating.
- 02A wet-bulb temperature above 35°C is considered dangerous, even for healthy individuals.
- 03Rising humidity levels are particularly problematic in coastal and densely populated urban areas.
- 04Extreme heat can disrupt brain function, leading to severe health consequences.
- 05Vulnerable individuals, such as those with a history of brain injuries, are at higher risk during heatwaves.

India is facing an alarming increase in heatwave intensity due to rising humidity levels, which complicate the body's natural cooling mechanisms. Wet-bulb temperature, which combines heat and humidity effects, is crucial for understanding this threat. According to Dr. Gaurav Batra, a neurosurgeon at Max Hospital in Vaishali, a wet-bulb temperature exceeding 35°C poses severe risks, even to healthy individuals. High humidity traps heat, accelerating dehydration and increasing the likelihood of heat-related illnesses like heat exhaustion and heatstroke. The brain is particularly vulnerable, with excessive heat potentially causing disruptions in normal functioning, leading to conditions such as confusion, seizures, or even coma. Vulnerable groups, including those with previous brain injuries, face heightened risks, as slight increases in body temperature can worsen their conditions. Awareness of the dangers associated with high wet-bulb temperatures is essential, as is recognizing early symptoms of heat stress, such as dizziness and fatigue. As climate patterns shift, understanding the implications of humidity on heatwaves is vital for public health and safety.
