The 32°C That Can Kill: Wet-Bulb Heat in India

Wet-bulb temperature combines heat and humidity into the one number that decides if sweat can cool you.

The old 35°C survival limit was theoretical; real bodies start failing near 31-32°C wet-bulb.

Coastal and humid cities like Mumbai and Kolkata hit dangerous wet-bulb levels at lower air temperatures than dry Delhi.

Estimate risk from your weather app: high temperature plus high humidity is deadlier than a bigger dry number alone.

Cooling, shade and stopping exertion beat hydration once wet-bulb climbs; water alone will not save you.
