Why does wind feel colder than still air?

Answer: Wind removes warm air near skin

Wind removes warm air near skin ✓ — Correct! Your body warms a thin layer of air next to your skin. In still air, this warm layer insulates you. But wind constantly blows this warm air away and replaces it with cooler air, forcing your body to work harder to stay warm. This 'wind chill' effect makes 10°C with wind feel much colder than 10°C without wind!

Moving air has less heat — Wrong. Moving air doesn't have less heat than still air at the same temperature. Wind feels colder because it removes the warm insulating layer of air around your body faster than still air.

Wind increases air pressure — Wrong. Wind doesn't increase air pressure in a way that affects temperature sensation. Wind feels colder because it removes the warm air layer your body creates, increasing heat loss.
