Question

energy and temps: wind chill and heat stress
why does it feel colder than the actual air temperature on windy winter days?
wind lowers the humidity and freezes water to our skin
wind makes the actual air temperature colder
wind reduces the evaporation rate from our skin
wind increases the loss of heat from our skin

Explanation:

On windy winter days, the wind sweeps away the thin layer of warm air that surrounds our skin. This increases the rate of heat transfer from our body to the environment, making us feel colder. The actual air - temperature doesn't change, but the heat loss from our skin is accelerated.

Answer:

Wind increases the loss of heat from our skin
