New Delhi: While some parts of the country are receiving rainfall, others are experiencing severe heatwaves that have made life difficult for people. Amid this, the term “Wet-Bulb Temperature” is being widely discussed. Experts believe this is a much more important indicator than regular temperature because it reveals how much heat the human body is actually feeling. Unlike the standard temperature that only measures air heat, wet-bulb temperature combines both air temperature and humidity to show how effectively the body can cool itself through sweat evaporation.
🌡️ Critical Alert: When humidity is high, sweat doesn’t evaporate quickly, weakening the body’s natural cooling process and making heat feel much more intense.

What is Wet-Bulb Temperature?
| Aspect | Explanation |
|---|---|
| Standard Temperature | Measures only air heat |
| Wet-Bulb Temperature | Measures air temperature + humidity together |
| What It Indicates | How effectively the body can cool itself through sweating |
| Why It Matters | High humidity prevents sweat evaporation, increasing heat stress |
💧 Simple Explanation: Wet-bulb temperature is measured by wrapping a thermometer in a wet cloth. The evaporation of water from the cloth cools the thermometer – just like sweat cools your body!
