Are you burning up? So Turn on the Fan right? Well, don’t leave it on when you leave the room!
Fans in general don’t cool the air off. They just cool YOU off. So if you leave them on when you’re not there, you’re just wasting electricity.
Your body cools itself off through the evaporation of sweat. And when air moves across your skin, that happens faster. It also carries heat away from your body. So fans actually cool you down in two different ways.
They don’t change the temperature of the air itself though. So unless you’re in the room with the fan blowing on you, they don’t do much.
