Which is Preferred for Sleep – Fan Positioning at the Bottom or Side?

Are you having difficulty sleeping due to the heat during the summer? Many people use fans to help them cool down, but does the placement of the fan make a difference? In this article, we investigate the best placement of fans for a peaceful night's sleep.


During the summer, it is common for people to use a fan while sleeping. Even when air conditioning is available, many people prefer to use a fan to circulate the air. However, it is important to consider the best placement for the fan in order to maximize its effectiveness and avoid potential health issues.

Turn on the fan while sleeping

Directly aiming the fan at a person while sleeping can cause the loss of moisture in the mouth and nose due to the wind. Additionally, the dust on the fan can potentially fly into the person and lead to allergic reactions.

When using a fan in a room with air conditioning while sleeping, the direct contact with cold air throughout the night can cause muscle stiffness and morning pain. The area of the body in direct contact with the fan will be colder than the rest of the body, affecting blood circulation and potentially leading to numbness of the facial nerves.

Therefore, there is no definitive answer to the question of whether it is better to place the fan at the feet, on the side, or on the ceiling when sleeping.

Do not aim the fan directly at the person when sleeping.

Proper way to use a fan while sleeping

  • Place the fan in a position where it can rotate and distribute the air throughout the room.
  • If placing the fan at the end of the bed, ensure it is at least 2 meters away to avoid blowing it directly on the face or head.

The placement of the fan when using it during sleep is crucial for ensuring safety and health. It is important to be aware of the proper placement in order to protect yourself and your family. Additionally, regular cleaning and maintenance of the fan is necessary to keep it in good condition.
