First of all, the wind speed should not be too large. Modern science believes that the indoor wind speed is best controlled at 0.2-0.5 meters per second, especially in the better ventilated room and in the place where there are leg winds, the fan's wind speed should not be too large.
Secondly, it is not appropriate to blow directly to the person, blowing directly to the wind is easy to invade the human body, especially in the weak or sweaty, it is best to let the fan blowing towards a corner; also, the fan should be blown to stop, it is appropriate to use the pendulum head of the electric fan for children, the elderly, the body of the weak, it is advisable to use the electric fan to blow the wind, because the "evil of the membrane, the gas must be weak! ". However, electric fans can be used to regulate indoor airflow, by indirectly cooling.
Lastly, pay attention to sweat more, do not immediately blowing in a sedentary or lying down situation, because at this time the whole body surface vasodilatation, suddenly subjected to cool wind blowing, often cause vasoconstriction, sweating immediately stop, thus causing the body to produce and dissipate heat out of balance, excess heat instead of excretion; in addition, the cool wind blowing after the decline in local defenses, the viral and bacterial invasion, which can produce Upper respiratory tract infection, muscle, joint pain, and some even abdominal pain, diarrhea.
