Adaptation to seasons
Seasonal variations influence the human body greatly. In spring and summer, yang qi releases and qi and blood easily tend to reach the surface. Therefore, the skin is loosened and sweat comes out. In autumn and winter, yang qi turns constricted and stored. At this time, qi and blood tend to reach the interior, thus, it manifests as tight skin, scanty sweat and profuse urine. Because of the above points, there exists the theory of "nourishing yang in spring and summer and yin in autumn and winter."
Conforming to geography
Dampness prevails in the east, heat in the south, dryness in the west and cold in the north in the Chinese geographical environment. People in different regions differ from one another in physique and susceptibility to diseases. Accordingly, different treatment should be based on specific situations during the daily life cultivation and rehabilitation of diseases.
Conforming to society
Chinese life cultivation experts throughout the history believe that healthy and longevous people view the world optimistically and positively. They do not approach society pessimistically and negatively. There exist conflicts of interests, unstable or unfair affairs in society everywhere at anytime. If viewing society pessimistically, people may get angry every day. This has bad effects on health. If approaching society optimistically, people may form a good spiritual environment. This is beneficial to life cultivation and rehabilitation. A Chinese saying goes like this "One is always happy if one is content with one's lot." The classic Yang Shen9 Yao Yu, or Essential Words for Life Cultivation, says: "If one smiles, one will become a little younger; if one is angry, one will become a little older; if one struggles with others, one will get a little thinner; if one yields, one will become a little stronger."
