*Dryness causes "allergies" and epidemics
Sudo Chiharu, Professor of health and environmental medicine at Nagoya University, Japan, found that the incidence rate of allergic diseases increased by more than 33% in the thirty years from 1961 to 1991. These diseases were caused by the decrease of immunity from the body in the environment of low humidity for a long time since the beginning of their lives.
Professor Inoue Shangyu of Waseda University in Japan collected epidemic related data from countries around the world in recent 100 years. The results showed that the epidemic prone period and the peak of mortality were in dry autumn and winter. It can be seen that in order to prevent epidemics in autumn and winter, we must pay attention to the supply of water.
*Harm of indoor air drying to different people
Children: the high incidence of many respiratory diseases (such as asthma, emphysema, bronchitis, etc.) is caused by the decline of body immunity due to people living in a low humidity environment for a long time since childhood; In addition, growing infants are vulnerable in all aspects, and the respiratory system, including trachea and bronchus, is weaker in resisting viruses.
Women: drying leads to excessive loss of water and accelerates aging. The skin's muscle fibers are composed of a large amount of water-soluble collagen. Drying makes the muscle fibers shrink due to rapid water loss. The drier the environment, the tighter the muscle fibers are. Over time, the muscle fibers may break, and the skin will have unrecoverable wrinkles. That's why the skin of Southerners is better than that of northerners.
Susceptible population: in winter and spring, influenza occurs frequently. The elderly and young children have weak physical resistance and are vulnerable to bacteria and viruses. Warm and dry is the best environment for the breeding and transmission of many viruses and bacteria. Therefore, creating healthy humidity and cutting off the transmission route of bacteria and viruses can effectively reduce the occurrence of influenza diseases.
Other hazards: in dry environment, furniture and musical instruments are easy to crack and damage. Drying can also make it possible for us to bring high-voltage static electricity of 2000 ~ 7000 volts. Due to the popularity of household and office appliances, static electricity is everywhere. It can be said that "you don't discuss it". Serious static electricity not only makes the skin spot and sore, but also makes people feel irritable, dizzy, chest tightness, throat and nose discomfort. Dry air mainly affects the skin, so you should apply more moisturizer to make it dry and crack. There is also the respiratory system, that is, the trachea and lungs, which are easy to get angry. There are few disease sources in dry places, because bacteria can breed only in places with moderate temperature and a little humidity. Places with more Gobi like Xinjiang and Afghanistan belong to dry places, so infectious diseases rarely occur in these places, which has something to do with the environment. Therefore, the only diseases caused by dry air are rhinitis and uncomfortable eyes Dehydration, that's all I can think of. Fire, dry skin,
