Using a fan correctly is an effective solution to keep you cool and sleep better during hot weather when air conditioning is not available.
On hot days, a fan is an essential cooling device. However, improper use of a fan may not meet your cooling needs and could even negatively impact your health.
Tips for Using a Fan to Help You Sleep Better
To improve sleep during the hot season, this simple tip involving an electric fan will enhance the cooling capability, making users more comfortable. This method is called “cross-ventilation.”
Cross-ventilation works by utilizing the movement of hot and cold air currents. Therefore, experts recommend creating cross-ventilation with a fan when the outdoor temperature is lower than the indoor temperature.
Simply place a standing fan in front of an open window. However, instead of directing the fan inward, turn it around to face outward. While it may seem counterintuitive to point the fan out of the window, this technique is the best low-cost and high-efficiency method to keep your bedroom cool.
Positioning the fan to blow air out of the window helps draw cool air from outside into the room while expelling the hot air that has accumulated inside. This will lower the room temperature, making it feel cooler and more comfortable.

Is it Better to Sleep with the Fan at Your Feet, Side, or on the Ceiling?
When the fan is directed straight at you, the airflow can dry out the moisture in your mouth and nose. Dust accumulated on the fan can also blow into your body, potentially causing allergic reactions or infections in open wounds.
Additionally, cold air blowing directly onto the body for extended periods (especially overnight) can cause muscle stiffness, leading to discomfort in the morning.
If you have ever slept with a fan blowing directly on you for a while, you may have noticed that the area exposed to the fan feels colder than the rest of your body. This can be harmful, as it creates a temperature difference on your skin, affecting blood circulation and potentially leading to nerve paralysis on the face.
The best thing you can do if you want to sleep with a fan is to place it in a position where it can rotate and disperse air throughout the entire room. If you prefer to place the fan at the foot of the bed, ensure it is at least 2 meters away. Especially avoid directing the fan towards your face or head.
