| In daily life, we often come up against this kind of situation: we feel fatigued and weak, have a poor appetite, feel dizzy and faint and other discomfort symptoms but when we go to hospital no disease is checked out in any case. During quite a long time, people have no knowledge of these phenomena and think that it's all because of low medical treatment or the patients are effeminate to make a fuss about an imaginary illness. Nowadays, people gradually get known of these phenomena: this condition of “feel sick but no disease is checked out” and condition between health and disease is called “sub-health”, “third state” or “latent period of disease” as well.
Sub-health is the new thought and new conception of medical field in afternoon of 80s, 20c and a important progress of medical science as well. According to a global survey of WHO, the real healthy people all over the whole world only account for 5%, people diagnosed as patients only account for 20% but 70% people are in state of sub-health. Especially among so-called “white collar”, sub-health state accounts for higher proportion. Although they are abundant in economic income but bear strong pressure from quick life rhythm, working pressure, heavy mentality burden and drastic competition. Additionally, mostly of these “white collars” are closed in wind-tight high buildings and large mansions and the air inside office are often polluted by people, decoration material and office equipment. A time passes, a series of discomfort symptoms such as having a sensation of dizziness, eye stimulating, fauces feeling dry and itchy, feeling oppressed in chest and being scatterbrained, which called as Sick Building Syndrome in foreign countries but actually the common sub-health state of white collar.
Research proves that when oxygen content of air is not sufficient but oxygen consumption of tense brainwork is terrible large, absorbing oxygen intermittently is a kind of tried and true measure. Especially when seeing stars, feeling oppressed in chest and the work efficiency descending, please lay down your work and absorb oxygen for 10 minutes. It will stimulate your energy and double you work efficiency. If absorb oxygen often, it will alleviate your sub-health state and enhance body constitution. |
