Wind makes you feel colder even when the air temperature is the same because it speeds up your body's heat loss through convection, reducing the layer of warm air surrounding your skin.
Mechanism of wind chill
When air moves quickly over the body's surface, it strips away the warm air layer that forms around the skin (the thermal boundary layer). This convection process increases heat transfer from your body to the environment, which your brain perceives as a lower temperature.
Factors that affect the sensation of cold
- Wind speed: the faster it blows, the greater the heat loss.
- Proper clothing: layers that trap warm air reduce the effect.
- Humidity: damp wind carries away more heat, intensifying the feeling of cold.
- Physical activity: generating internal heat can partially counteract wind cooling.
Consequences and prevention
Wind chill is the basis of the so-called
