Fans can make you feel cooler because they encourage moisture from your skin to evaporate. However, they don't actually change the temperature of the room. Air conditioners draw moisture from the air to reduce its temperature.
"Most electrical fans are designed to be able to run continuously for several hours at a time, for example overnight or during the day, but you'll also need to keep in mind doing that continuously for long periods can cause wear and tear on the motor and other components, shortening its lifespan," continues David.

conclusion. Ceiling fans are designed for prolonged use and can run 24/7 without much trouble. However, just like with any home appliance, it's not totally safe to leave them running unattended.
