Why Delhi feels hotter than what temperatures show
The real feel, the weather apps helpfully tell us, is always a few degrees higher. The IMD's official data reflects the temperature of the city air measured under standard conditions, while thermal cameras record the temperature of surfaces.On hot days, roads, concrete, vehicles and other exposed surfaces can become substantially hotter than the air around them. That's the difference just one tree can make."Dr A Fathahudeen, a pulmonologist, says that the core human body temperature is 37C and prolonged exposure to high heat can make it rise."When it exceeds 40C, the body ceases to work normally.
