It's a nice day, but I'm sleeping.

Son, if you want to live longer and don't want to lose your life, you should blow less.

Being in an air-conditioned room for a long time will lead to the closure of sweat glands and affect normal metabolism and secretion; Sitting still and not exercising for a long time will cause unbalanced neck movement and affect neck muscles, nerves, spinal cord and blood vessels. Over time, it will lead to local cervical spondylosis, ranging from stiff neck, stiffness, pain, heavy shoulders, weakness of upper limbs and numbness of fingers, to abnormal feelings such as headache, dizziness, decreased vision, nausea, and even out of control of urination and defecation.

Attention should also be paid to improving the fixed sitting posture in air-conditioned rooms. After working and watching TV for about 1 hour, you should change your posture, or do a short neck flexion and extension exercise and naturally rotate left and right to improve the blood circulation of the neck and relieve the muscle fatigue of the neck. People who work at their desks for a long time should pay attention to the height of desks and seats, try to avoid excessive bending and neck flexion, and it is best to use a movable desk with a half slope.

Once the cold air breaks through the fragile "defense line" of the respiratory tract, cold symptoms such as cough, sneezing and runny nose appear, that is, upper respiratory diseases. This kind of cold is usually called a cold. On the one hand, because of frequent access to air-conditioned rooms, the body can not adapt to the uneven temperature; Second, because the air-conditioned rooms are closed, there are many people in the room and the air circulation is poor. If a person has cold symptoms, it will soon spread to others.

Air conditioning causes serious lower respiratory diseases, especially pneumonia. Especially when working and studying under central air conditioning, central air conditioning is very suitable for the spread of Legionella, and the incubation period is about 2~ 12 days. Although the upper respiratory tract is unresponsive, it has fever, chills, muscle aches, dry cough, no phlegm or less phlegm. If not treated in time, it will continue to have fever, dry cough and chills.

In addition, although the room is cold, the humidity is too low, which is not good for people's eyes and nasal mucosa. A dry environment is suitable for the survival of bacteria and viruses. People should be especially careful when their noses and throats are dry.

Always go in and out of the air-conditioned room, there must be a temperature transition, for example, turn up the temperature or turn off the air conditioner first, and be sure to dry the sweat when you enter the door. Stay in an air-conditioned room for a long time, drink as much water as possible, and often mop the floor with a mop filled with water to moisturize. If you have cold symptoms, you should go to the hospital in time to avoid deterioration and cross infection.

It is often seen that young people and overweight people keep the air conditioner on all day at home, or enter the house from the outside sweating and turn the temperature down very low. Some people even run under the air conditioner and blow directly for a while, but they don't know that when blowing directly, the wind speed increases, the temperature will drop by 3℃-4℃, and their heads will faint. Moreover, sudden cold air can easily stimulate sweat pores to contract suddenly, causing headaches.

I often hear people who often sit in air-conditioned rooms say, "I feel dizzy and see stars, and forget things." According to Director He, this is a common brain imbalance reaction caused by air conditioning disease.

The negative ions contained in the air can inhibit the central nervous system and relieve brain fatigue. But the air conditioner absorbs too many anions, which makes more and more cations in the room. The imbalance of anion and cation also makes the human brain nervous system unbalanced.

Try to avoid staying in an air-conditioned room for a long time. If possible, it is best to keep the room temperature around 24℃, and the temperature difference between indoor and outdoor exceeds 7℃. Always open the window for ventilation to ensure indoor and outdoor air convection. 1-3 hours after startup, it is best to turn off the air conditioner for a period of time and open the window to breathe fresh air. Natural cold air is the best. If conditions do not permit, it is best to go to outdoor corridors and other places with windows for air exchange every hour, especially during lunch break. The most important thing is not to blow directly under the air conditioner because of the heat. Once you feel dizzy, you must leave the air-conditioned room in time and breathe fresh air.

Many people don't realize the harm caused by blowing air conditioner for a long time, and think it's just a cold, dizziness and headache, especially young and strong people don't care. As we all know, cold air does great harm to joints. If you don't pay attention to keep warm, you will easily get arthritis in old age, and it is difficult to cure it again.

Young people often don't pay much attention to joint pain caused by air conditioning, but long-term air conditioning will cause such problems. In summer, the outdoor air is hot, and people generally wear less. But the indoor air conditioner blows badly and the clothes are so thin. Such a low-temperature environment will stimulate the rapid contraction of blood vessels and poor blood circulation, leading to joint injury and cold pain, such as stiff neck and back, sore waist and limbs, cold and numbness in hands and feet.

In addition, too "cold" in the room can easily lead to weakened gastrointestinal movement. In addition, people often eat cold drinks in summer, and both inside and outside the intestine are controlled by "cold". It's not surprising that many people pull and vomit.

After coming home from work, take a warm bath first, and don't let the water overheat, so as not to stimulate nerves and joints, then massage yourself, or apply a warm towel to the joints. It is certainly better if you can do proper exercise, such as running, playing ball and doing yoga.
