What's the harm of blowing air conditioning in the room all the time?

1, staying in an air-conditioned room for a long time, the cold will go deep into the body step by step, damaging our yang, leading to deficiency of spleen and yang, digestive disorder, abdominal pain and diarrhea. In addition, eating too many cold drinks or eating unheated food in the refrigerator can easily cause acute gastroenteritis.

2. Stay in the air-conditioned room all the time, the air is not circulating, and the body's resistance becomes weak. Moreover, when you enter a low-temperature air-conditioned room from the hot outdoor, it is easy to catch a cold, some people will cough, and even cause more serious diseases, such as asthma and pneumonia. Young people are greedy for cold, it is easy to adjust the air conditioning temperature very low, and there are many colds and fevers. Some basic diseases of middle-aged and elderly people, such as asthma and bronchitis, are easily induced.

3, wearing less in summer, long-term exposure of legs and arms to air-conditioned low-temperature environment, long-term cold stimulation of shoulder joints, knee joints, waist and so on. The joints are prone to catch cold, joint pain, muscle soreness and other symptoms, which are more common in women wearing short skirts and shorts and the elderly suffering from osteoporosis, and are easy to induce the original cervical spondylosis and scapulohumeral periarthritis. Neck, shoulder, waist and leg pain caused by cold air stimulation of air conditioning is not a very serious disease. If there is no organic disease, the condition will generally not worsen, but the leg is a little uncomfortable.

After staying in the air-conditioned room for a long time, I often hear people say "dizziness, headache, poor memory and fatigue." . 。” This may be because the air quality in the enclosed space of air-conditioned room is poor, especially the oxygen content is not enough. If people stay inside for a long time, their brains may suffer from various discomforts due to lack of oxygen, such as dizziness, headache, memory loss, decreased work and study efficiency, laziness, etc. What's more, some people can't sleep at night, which is similar to neurasthenia.

5. People in China drink more hot water since childhood, while women always pay attention to keep warm during menstruation. If they stay in an air-conditioned room for a long time, the change of environment will make their bodies have some stress reactions because they are not adapted. If it is during the official holiday, women with cold uterus, cold accumulation, blood stasis and poor menstruation may be more likely to be recruited.

6. The myocardial infarction is switched from a low-temperature air-conditioned room to a high-temperature outdoor room, and the blood vessels contract violently; Suddenly from the high temperature outdoor into the low temperature air-conditioned room, blood vessels dilate again; Repeated tossing leads to large fluctuations in blood pressure, which may induce myocardial infarction, especially in the elderly with fragile blood vessels. Moreover, alternating hot and cold is easy to catch a cold, and if it is complicated with serious infection, it may also endanger the heart.

7. Respiratory tract is the most vulnerable part of human body. If the air conditioning temperature is too low, it is easy to break the fragile defense line of the respiratory tract, and even cold phenomena such as coughing, sneezing and runny nose appear, which is also a kind of respiratory diseases. If the air conditioning temperature is too low, it will cause pneumonia in severe cases, especially when working and studying under central air conditioning. The incubation period is generally 2~ 12 days. Although there is no response to respiratory diseases, it will cause fever, chills, muscle aches, dry cough, no phlegm or less phlegm. If not treated in time, it will cause fever, dry cough, and serious death due to respiratory failure.

8, long-term blowing air conditioning, the relative humidity is also significantly reduced, which is not good for human eyes and nasal mucosa. When people feel dry nose and throat, they should be careful of virus invasion. At the same time, when the dust and dust mites in the house cannot flow out, people with allergic characteristics are also prone to allergic reactions. In addition to the air conditioning temperature should not be too low, but also should often open the window ventilation to maintain air convection.

9. Air conditioners that have not been used for a long time have absorbed a lot of dust and mold on the filter screen. When the cold blower of the air conditioner blows into the room, it acts on the human skin or is inhaled into the human body. Because the air conditioner is turned on indoors, the environment is closed and the air circulation is not smooth, which greatly increases the induced probability of eczema. In addition, long-term low air conditioning temperature will produce a lot of condensed water, which will make the air drier and drier, and most of the skin will be exposed, which will accelerate the loss of skin moisture and is also the main reason for eczema recurrence.

What should I pay attention to when blowing air conditioning?

1, wear socks when using air conditioning at night: it is best to wear stockings when using air conditioning when sleeping to prevent your feet from catching cold. In addition, when the elderly use air conditioning during lunch break or sleep at night, they should also wear long-sleeved pajamas and pajamas and cover them with thin air-conditioned quilts to prevent their lungs from catching cold.

2. The air conditioner is stressed: If the air outlet of the air conditioner blows directly against the sofa or bed in the living room, the cold air coming from the face will make the body cold. It is best to install the air conditioner above the bed to avoid cold air blowing directly on people.

3. The air conditioning temperature should be appropriate: the difference between the air conditioning temperature and the outdoor temperature should not be too big, and it should not exceed 5 degrees. Generally speaking, the most suitable air conditioning temperature for human body is 24℃ to 27℃.

4. Don't smoke in the air-conditioned room: Smoking in the air-conditioned room, because the indoor air is not updated by the outdoor air, harmful gases such as nicotine and carbon monoxide in cigarettes will accumulate all the time, which is harmful to health for a long time.

5. "Bath" the air conditioner regularly: There will be many flocculent attachments on the air conditioner dust filter net, among which fungi, dander and dust mites can cause allergic skin diseases or induce asthma. When people stay in such air-conditioned rooms for a long time, they will feel dizzy, nauseous and even induce respiratory diseases.

6. Open the window regularly for ventilation: When using air conditioning, you must pay attention to ventilation. It is recommended to open the window regularly every day, turn off the air conditioner and let the fresh air circulate. Especially in crowded environment, it is best to turn off the air conditioner and ventilate the room after using it for a period of time to avoid respiratory tract infection caused by poor ventilation.

7. Sweating is not suitable for blowing: when entering the room from the outside, it is best to dry the sweat with a towel first, and then turn on the air conditioner. Blowing cold air directly when sweating, pore contraction will block pores, which may easily cause physical discomfort and may also cause a cold.

8. Don't face the air conditioner outlet: When blowing the air conditioner, don't face the air conditioner outlet. Because the air conditioning at the air outlet of the air conditioner is relatively large, and it is directly blown on the body, it is easy to catch cold.

9. prepare a coat: especially for white-collar workers working in the office, it is necessary to prepare a coat. Because everyone has different adaptability to temperature, some people think this temperature is just right, but others think it is too low. Therefore, when you feel cold, you can put on an extra coat and keep warm.

The most suitable setting of air conditioner is 26℃

When the temperature is 25℃, the relative humidity is 50%, and the air velocity is 0. 15m/s, the human body is in the most normal and ideal state of thermal balance, that is to say, it feels most comfortable and responds most appropriately. The effective temperature felt by human body is slightly lower than the indoor air temperature, generally about 1~2℃, that is, although the air supply temperature of air conditioner is slightly higher, the temperature actually felt by human body is not that high. Therefore, the control temperature of the air conditioner is adjusted to about 26℃, and the human body will feel more comfortable at this time.
