My 3-year-old son hasn't caught a cold for a long time, and he caught a cold as soon as he blew the air conditioner recently. What happened?

This is air conditioning, not a cold. You should go to the hospital.

Air conditioning disease, air conditioning brings people comfort, but also brings a "disease." People who work and study in air-conditioned environment for a long time will have symptoms such as stuffy nose, dizziness, sneezing, tinnitus, fatigue, memory loss, and some skin allergies, such as tight and dry skin, allergies, and skin deterioration. This phenomenon is called "air conditioning syndrome" or "air conditioning disease" in modern medicine.

People's skin temperature is different, that is, the temperature of limbs is lower than that of trunk, the temperature of hands and feet is lower, and the ability of human body to adjust temperature is powerless. In an air-conditioned clean room, negative ions are almost equal to zero. Air negative ions are negatively charged air particles, which can cheer people up and improve human functions. They are called air "vitamins", and the lack of negative ions can make people feel headache.

preventive

◆ 1. When using air conditioner, be sure to pay attention to ventilation. Open the window regularly every day, turn off the air conditioner, and add air for ventilation to keep a certain amount of fresh air indoors. It is best to clean the air conditioner once every two weeks. ◆2. When going out in an air-conditioned environment, you should first move in the shade for a while, and then move in the sun after your body adapts; If you are in an air-conditioned room for a long time, you should go outdoors more and drink more boiled water to speed up your metabolism. ◆3. The room temperature and outdoor natural temperature of the air conditioner should not be too high, and should not exceed 5 degrees. It is best not to use air conditioning at night. It is safer to turn off the air conditioner when you are asleep. Being outdoors before going to bed is conducive to promoting blood circulation and preventing air-conditioning diseases. ◆4. When working and studying in an air-conditioned environment, don't let the cold air from the air outlet blow directly on your body. It is best not to blow air conditioning directly when sweating, so the temperature drops too fast and it is easy to get sick. ◆5. Smoking is prohibited indoors. ◆6. Always keep your skin clean and hygienic. This is due to frequent contact with air-conditioned environment, sudden changes in heat and cold, and bacteria attached to the skin are easily blocked in sweat glands or sebaceous glands, causing infection and suppuration. Therefore, always take a bath and keep your skin clean. ◆7. Use disinfectants to kill and prevent the growth of microorganisms. ◆8. Add a dehumidifier to prevent bacterial growth. ◆9. Don't turn on the air conditioner in the stationary car, so as to prevent the carbon monoxide discharged from the automobile engine from flowing back into the car and causing an accident, that is, carbon monoxide poisoning. ◆ 10. Pay attention to the clothes in the workplace to meet the requirements of keeping warm in an air-conditioned environment. ◆11Turn on the air conditioner above 26 degrees Celsius, which saves energy and is not easy to get sick. The prevention of air-conditioning diseases is mainly the above ten items. If you have symptoms such as cold, fever, pneumonia, mouth and eyes askew, you should consult a doctor in time.

New preventive technology

At present, the world's leading high-purity air negative ion technology is an "ion converter" technology invented by Japanese scientist Moriguchi, MD, who is known as the "first person of negative ions". It is a patented technology that uses the natural resources of the earth to generate natural air negative ions. It is understood that since the beginning of this year, products and technologies related to this important invention have been introduced to China through the internationally renowned brand Sailumei founded by Dr. Horikou. The air negative ions produced by it are no different from those produced in nature, which is very suitable for regulating human body functions and plays an important role in improving physical fitness and maintaining health. ◆ The introduction of this technology will bring China customers the most advanced environmental improvement equipment in the world, and will be able to meet the needs and tastes of the most critical building owners, families and car owners in China. With the release of Sailumei series products, the definitions of environmental improvement equipment and negative ion devices of top central air conditioners for home and vehicle are updated again. In summer, the temperature is high and the clothes are thin. If you stay in a low temperature environment for a long time, the feeling of "cold" will be transmitted to the thermoregulation center, instructing the skin blood vessels to contract and the sweat glands to stop secreting, so as to reduce heat dissipation and maintain body temperature. The feeling of "cold" excites the sympathetic nerve, which leads to the contraction of blood vessels in abdominal cavity and the weakening of gastrointestinal movement, resulting in many corresponding symptoms. Cold stimulates female body, which can affect ovarian function and cause ovulation disorder and menstrual disorder. In addition to the above cold factors, doors and windows are closed and there is a lack of fresh air; The temperature difference between inside and outside the air-conditioned room is too large; And although there are air-conditioned filters that can remove most of the dust, they can't remove microorganisms, and pathogenic bacteria can easily board, grow and reproduce in air-conditioned rooms ... these are the causes of diseases.

Preventive diet

In addition to often opening windows for ventilation, Koreans also have a good way to fight air-conditioning diseases with celery porridge. Wash celery, cut into pieces, put cold rice into a pot, add water, add celery after the rice becomes sticky, add sesame oil and appropriate amount of salt after a little cooking. Air-conditioned rooms are cooler, and celery is a cool food. Why can it fight air conditioning disease? Celery, celery and celery have the same composition and function, and are rich in provitamin A, vitamin B 1, B2, vitamin C and vitamin P, as well as trace elements, protein, mannitol and dietary fiber. In a closed air-conditioned room, the internal heat of the human body cannot be discharged, which is easy to cause diseases. Celery has the functions of clearing away heat, promoting gastrointestinal peristalsis and helping to dispel summer heat. When buying celery, you should choose short and thick stems and few green leaves; The freshness of celery mainly depends on whether the leaves are straight. The leaves of fresh celery are straight. Celery stored for a long time, the tip of the leaf will tilt, the leaves will become soft, and even yellow and rust. Why can drinking porridge fight air-conditioning disease? In a closed air-conditioned room, people's body temperature regulation, water and salt metabolism, circulation, digestion, nerves, endocrine and urinary system will all change, and the loss of appetite in summer will also limit the absorption of nutrients. Therefore, fight against air conditioning and cook porridge with cold rice.

Eating porridge when you are sick is a good way to supplement nutrition. Drinking porridge can enhance appetite and replenish physical strength; Drinking porridge can replenish water for the body and effectively prevent constipation; It can also prevent colds, prevent dry throat and regulate the stomach. Why do you cook porridge with cold rice? Casserole porridge is the best, but it's a "slow work" thing, but office workers can't spare the time. Cooking porridge with cold rice saves time and is nutritious. What are the benefits of adding sesame oil to porridge? Reminder, remember to add sesame oil after cooking porridge. This fragrance is not only appetizing, but also beneficial to the digestion and absorption of food. Sesame oil is rich in nutrition and vitamin E, which can promote cell division and delay aging. Sesame oil can protect blood vessels. Sesame oil contains about 40% unsaturated fatty acids such as linoleic acid and palmitic acid, which is easily decomposed, absorbed and utilized by human body, promotes cholesterol metabolism and helps to eliminate deposits on arterial wall. Sedentary people are prone to habitual constipation. Drinking a mouthful of sesame oil on an empty stomach in the morning and evening can relax the bowels. Drinking sesame oil before drinking can protect the mouth, esophagus, cardia and gastric mucosa.
