Blowing fans and air conditioners are common cooling devices, but their working principles and effects on human bodies are different. Blowing fans can enhance air circulation by accelerating air flow, resulting in cooling effect, but will make the skin lose moisture and oil, resulting in skin dryness, physiological imbalance, skin itching and other discomfort. Air conditioning can change the indoor temperature and humidity by cooling or heating, and reduce the pollutants in the air, but it may also make the indoor air too dry, leading to problems such as dry mouth and dry skin.
Although the blower fan and air conditioner have a certain cooling effect, we should pay attention to the reasonable dosage and appropriate distance when using them, and at the same time keep the indoor humidity and the existence of green plants to protect human health.
