1. Common Errors in Electric Fan Usage Resulting in Many Families Rushing to Hospitals
In these days of unpredictable temperature shifts, incorrectly using an electric fan while sleeping can inadvertently lead to respiratory issues for individuals.
1. Turning the fan directly towards the body, even without changing direction for an extended period:
This method may cool the body but can be detrimental to health. Continuous airflow on a specific skin area can lead to faster evaporation of sweat, affecting internal organs and causing symptoms like headaches, colds, and dizziness...
Therefore, if you turn on the fan while sleeping, it's advisable to point it towards the wall or ceiling for better air circulation. Ventilation should be gentle, and using an oscillating fan is preferable.
2. Setting the fan speed too high
When the environmental temperature exceeds 30°C, which is close to the body temperature, the fan's airflow is also at a high temperature. Setting the fan to the highest speed can lower the surface temperature of the skin, leading to clogged pores, ineffective sweat evaporation, and the body feeling hotter, resulting in fatigue, exhaustion, and back pain. Therefore, don't crank up the fan speed just because it doesn't feel cool enough.
3. Using the fan when the body is sweating excessively
During intense physical activity, blood vessels are dilated, and sweat production increases. The fan's air can hinder the sweating process, and sudden constriction of blood vessels is extremely dangerous. Therefore, it's advisable to wipe off sweat with a dry towel before using the fan from a distance to cool down gradually and ensure health safety.
4. Prolonged use of the fan
Electric fans regulate room air, making it more breathable. Directing the fan towards the body for an extended period accelerates sweat evaporation, reducing hydration and causing a feeling of dehydration, fatigue, and lack of energy if sufficient water is not replenished.
If you're using a fan for an extended period, ensure you maintain adequate hydration for your body.
