ceiling fans only push the air around them, they have no cooling fuctionality. Ceiling fans don't have any way of cooling the air they circulate, but that is also true of fans placed on work desks or floor stands. However the human body feels more comfortable if the skin feels cool, and fans help to do this by evaporating more moisture from the skin, due to the flow of air over it. However there are certain aspects that should be taken into consideration; 1-that energy transfer takes time, and when air moves it does not transfer its heat to the body because the time of transference decreases, for example if you holds a hot cup of tea you will get burned, but if you touched it quickly you won't be burned.
2-Also if the temperature is low and you are covered by a blanket you will the air inside that blanket and you will be warm, accordingly if there is a fan the air won't stay around your body to be warmed. 3-Finally when air circulates this will increase the amount of air inside the room thus more air will absorb more heat from your body(if the air's temperature is less than the body' temp) until the thermal equilibrium occures. If there is no one in the room to feel the moving air then there is no effect other than wasting electricity to run the fan. Window fans on exhaust or intake do have a cooling or warming effect depending on the outside air.
The name for a picture that looks like it's moving is called an optical illusion or a motion illusion.
A ceiling fan is a common house appliance which is attached to the ceiling and uses an electric motor to rotate blades or paddles in a circular motion. Ceiling fans help cool a room by moving air which causes evaporative cooling. Fans range in size from 36 inches to 56 inches using 55 to 100 watts, a typical 48 inch ceiling fan will use 75 watts.
Centrifugal force is observed in a ceiling fan. Thrust force is what moves a car moving on the road.
Illusory motion is also know as motion illusion. Illusory motion is an optical illusion in which a static image appears to be moving due to cognitive effects of interacting color contrasts and shape position.

The frames are the signal images within the animation,. The frames are displayed in a specific sequence at the specific speed to create the illusion of the animation moving.
A person who can speak without moving their lips is commonly referred to as a ventriloquist. Ventriloquists are skilled performers who manipulate their voice to create the illusion that a puppet or dummy is speaking.
The air moving across the moisture causes it to evaporate. Evaporation being a cooling process, it makes you feel cold.

There is insufficient airflow for cooling
Because the earth is rotating thus creating the illusion that the stars are moving across the sky.
