How much does a ceiling fan cool the air?

Fans don't cool the air; they actually make it a little warmer. By causing more air to cross the surface of your skin, fans increase the rate of evaporation of your perspiration. The process of evaporation draws heat from your body, making you feel cooler. The less water vapor that is in the air, the more rapidly the body cools.
