Which is more likely to catch a cold by blowing an air conditioner or a fan?

If the air is not circulated with air conditioner and cannot be improved, symptoms such as nasal congestion, dizziness, sneezing, tinnitus, fatigue, memory loss, etc., as well as allergic characteristics, such as tightness and dry hair, easy allergies, and deterioration. This kind of phenomenon is called in modern medicine"Air conditioning syndrome"or"Air conditioning sickness" 。

For"Air conditioning sickness"For prevention, disinfectants are used to kill microorganisms in the air conditioning unit. Disinfectants can be reused to prevent microbial regrowth. Since the humidity regulator of the air conditioner is a tool that promotes the spread of bacteria, it is most important to install a dehumidifier to reduce the relative humidity in the room and thus prevent the growth of bacteria.

Do not enter an air-conditioned room immediately after strenuous exercise, so as not to cause the open pores to shrink suddenly, which may cause cold. There is a large difference between the temperature between the air-conditioned room and the outside, so it is not advisable to stay indoors for a long time. You should let ** have the opportunity to sweat, drink more water, and make the pores unobstructed to speed up metabolism.

When possible, it is best to use an open-system air-conditioner to keep the indoor and outdoor air fresh and circulating. In both summer and winter, after spending an hour or two in an air-conditioned room, you should open the window for ventilation. For example, in summer, you can open the doors and windows at 4 to 5 o'clock in the morning, and in winter at 1 or 2 o'clock in the afternoon, to increase the circulation of fresh air.

So blow the fan.

I feel that blowing the fan is easy to catch a cold, I often blow the fan for a whole night and catch a cold the next day, because the fan is blowing at people, and the pores are open when people sleep, so it is easy to catch a cold, and the air conditioner is for the air refrigeration of the whole room, and our human body is relatively good at the price to adapt to that environment!

Air conditioning. Because the wind blowing from the fan is not cold.

You can blow the air conditioner, but you have to use it correctly. Keep your abdomen warm and ventilated.

In terms of comfort research; The most suitable ambient temperature for the human body is 27 degrees C, and the temperature difference between the thermal shock and the human body is about 5 degrees C (which means entering and exiting between two different ambient temperatures, such as between indoor and outdoor), so the most appropriate setting temperature of the air conditioner at home is between 26 and 28 degrees C.

By setting this temperature, you can not only achieve a comfortable environment that is neither hot nor cold, but also save energy consumption, electricity and money.

It is also recommended to buy an inverter air conditioner, because when the inverter air conditioner reaches the set temperature, it will reduce the frequency and power to operate, at this time, the most power-saving, the compressor does not stop, runs at the most appropriate frequency, quiet, power-saving, and the room temperature is stable between plus and minus C, which is the most comfortable and suitable for children and the elderly.

Therefore, the set temperature of the air conditioner must not be too low, and it should not blow directly.

In addition, when used during the day, it is best to open the window for ventilation every 1 2 hours and ventilate it once every 5 10 minutes to ensure that the indoor air is clean. It is important to use air conditioners healthily.

If you have any other questions, please feel free to discuss them.

Definitely. The air conditioner was blowing cold air. It's easy to catch a cold if you blow for a long time, so pay more attention.

It should be, and blowing the air conditioner for a long time will get air conditioning disease.

The fan is appropriate, so that the outside temperature will not be too low, and at the same time, it will not let the child get cold, and the child will have a good experience.

Personally, I think it is more appropriate to blow the air conditioner, which can adjust the temperature at will and will not cause harm to the child's body.

It is more appropriate to choose a fan, and you must pay attention to the temperature, so as not to cause the temperature to be too low and affect the health of your child.

Improper use of fans and air conditioners is harmful to the human body. Air conditioners have "air conditioning sickness", and fans also have "fan sickness". Only the right use is the best.

Our human body has a self-regulating mechanism for temperature, and the air conditioner will make the temperature of the whole room drop. If we suddenly move from the hot outdoors to the cool room, if this temperature difference is too large, our body will not be able to adapt well, and some symptoms such as runny nose, nasal congestion, and fatigue will appear.

The cooling principle of the fan is different from that of the air conditioner, which directly lowers the indoor temperature, while the fan uses the principle of the human body to evaporate the sweat on the surface of the body in a hot environment to cool down. The fan blades stir the air to make the air flow, accelerating the evaporation of sweat on the body surface, so as to achieve the effect of cooling. Because the fan will accelerate the evaporation of sweat on the body surface, blowing the fan directly for a long time is easy to cause symptoms such as colds.

Fair use is the last word";

In fact, these so-called "air conditioning diseases" and "fan diseases" are actually based on people's irrational use of air conditioners and electric fans. If used wisely, fans and air conditioners will not have much impact on our health.

When using an air conditioner, it is generally recommended not to set the temperature too low, and the difference between the indoor temperature and the outdoor temperature should not exceed 7 degrees Celsius. Controlling the temperature of the air conditioner at about 26 degrees Celsius can not only keep the room relatively cool, but also save electricity at this temperature.

When using the fan, try to avoid blowing directly on the body for a long time, and keep the fan away from people as much as possible. When sleeping at night, don't turn the fan on too high a gear, keep the fan at a relatively moderate speed, so that the wind will be more gentle with the fan, and the white noise of the fan can also provide us with the effect of sleeping.

In addition, air conditioners and fans should also be cleaned regularly. The fan may accumulate dust after some time, which can be seen with the naked eye. However, the dust of the air conditioner is difficult to see, but the air conditioner is more likely to accumulate dust than the fan and breed the fine nightshade fungus.

For the health of you and your family, be sure to clean your air conditioner and fans regularly.

"Air conditioning sickness" and "fan sickness" are not things that can be photographed. These are actually the result of our incorrect and unreasonable use. Of course, even if it is hot in summer, don't stay in an air-conditioned room all the time, and still do more exercise. If it's too hot during the day, you can choose to go out at night.

1. Blowing the air conditioner is more likely to catch a cold.

Blowing air conditioning is mainly to reduce the indoor temperature, so that the indoor and outdoor temperature difference is formed, if you frequently enter and exit, the capillaries in the body open and close, it is easy to make the cold into the body and cause cold.

And blowing the fan only makes the air flow and there is no large temperature difference, so blowing the air conditioner is more likely to catch a cold than blowing the fan.

2 According to the actual situation.

If the weather is too hot and the fan is not enough to relieve the heat, you can consider turning on the air conditioner; If the weather is not so hot, blowing a fan can also relieve the heat, you can also consider blowing a fan.

However, if it is blowing the air conditioner, pay attention to the air conditioner should not blow directly, and adjust the temperature of the air conditioner to 28 or more; If it is a blowing fan, do not blow directly at it for a long time, it is recommended to shake your head and place it at a distance to keep the natural wind as much as possible.

3. Although blowing the air conditioner is more likely to catch a cold, it does not mean that blowing the fan will not catch a cold.

The reason why the fan blows a cold is because the sweat on the side of the blowing fan evaporates quickly, and the body surface temperature drops significantly; On the side that is not blown by the wind, the sweat evaporates slowly, the epidermal temperature is relatively high, and the blood vessels on the body surface are in a state of relaxation, which eventually leads to the loss of balance in the blood circulation of the human body and the uneven excretion of sweat, thus inducing headache, dizziness, general malaise, fever and other cold symptoms.

41.If you sweat a lot, before entering the air-conditioned room, you must change out of sweaty clothes, dry the sweat on your body, and do not blow the air conditioner immediately to avoid causing a cold.

2.Blow the air conditioner for about 1-3 hours, keep the window open for ventilation for 10-15 minutes, ensure indoor air convection, keep the indoor air fresh, and avoid the indoor air from breeding more bacteria.

3.When blowing the air conditioner, keep the indoor temperature constant at about 26-28 at any time, and the temperature difference between indoor and outdoor should not exceed 7 to avoid colds caused by the large temperature difference between indoor and outdoor.

4.If you sit for a long time in the office, such as typing, writing, wiring, etc., you should appropriately add clothes that are easy to put on and take off, and protect the knee joints and other parts with towels and blankets, and pay attention to walking around more to increase peripheral blood circulation.

1.Although it is hot in summer, the temperature at night is relatively low, and it is recommended to adjust the timing of the fan when blowing the fan to sleep, and when the temperature is low in the early morning, the fan will naturally stop.

2.If you blow the fan for a long time at night, you should turn the fan to the minimum and maintain the feeling of natural wind as much as possible, so that it will not be uncomfortable to blow the fan for a long time, and it can also prevent cold.

3.Generally speaking, the blowing fan should be placed at the end of the bed, because blowing on the head for a long time is easy to cause headaches, but even at the end of the bed, you should pay attention to the warmth of the lower limbs.

4.When blowing a fan to sleep at night, pay attention to covering the area around the navel or upper body with a towel or small blanket, because the navel is prone to cold and cold, causing people to have abdominal pain, diarrhea, headache and other symptoms.
