Does a fan lower the temperature?

A fan does not lower the actual temperature of a room; instead, it helps to circulate air, creating a wind-chill effect that makes you feel cooler on your skin. By increasing evaporation of sweat from your body, fans enhance your body's natural cooling process. However, in a closed space without proper ventilation, fans can contribute to heat buildup. For effective cooling, they are best used in conjunction with air conditioning or in well-ventilated areas.
