We know that the sun is the only source of energy on the earth, and the place where the sun can shine is the day, and the place where the sun can shine is the night. The sun brings warmth to the earth, promotes the autumn harvest and winter of the earth, as the sun travels south, the back pot will enter the cold winter, the earth will kill the cold, all life, trembling in the cold wind, cold-blooded animals have to enter hibernation, trees shed their green leaves, flowers and grasses end their lives... Everything in the world adjusts with the trajectory of the sun, and all life is conceived, grown and matured, which is the result of solar photosynthesis, even coal, oil, natural gas and thermal power, nuclear power, wind and wind power, etc., it can be said that all energy sources are the conversion and storage of solar energy, which is the so-called "growth of all things depends on the sun". It is unimaginable that the earth will not be illuminated by the sun, the moon will not become the moon because there is no light, the stars will not be able to shine because they have lost their light source, and the earth on which we live will be a dark and cold lifeless big ice ball, and there will be no life at all. There is no way to talk about birds and flowers, small bridges and flowing water. Because there is no supply of the sun, life on Earth loses its basis for survival.
And what does man depend on for his survival? Rely on nature as yang. In the same way, because the human body has yang qi, it can exert its harmonious and protective functions, otherwise it will incur the invasion of disease and evil. It is easy to think of it from this that if there is insufficient yang qi, it will be sick, and if there is a lack of yang qi, it will be sick. For example, the spleen and stomach part of the yang is insufficient, it is easy to appear food is not digested, it is loose abdominal pain, touch the stomach will find it relatively cool, this is the lack of yang, so the yang can be called the root of the body, is the root of health care.
So how to cultivate yang qi?
The biggest yang between heaven and earth is the sun, and the changes of the sun directly affect the changes of the yang of the human body. People who stay in office buildings for a long time always feel that they are not angry, and if they can take time to bask in the sun every day, they will feel that the whole person has a lot of spirit, which is the power of the sun to us. So we say that only by following the sun can one find the inner strength.
But modern people, every day to get up very early to go to work, spring, summer, autumn and winter are a time, the sun went down early at night, but also have to work overtime, a day can not see the face of the sun, so it leads to the decline of yin and yang and cause illness.
Secondly, living habits have also changed, the ancients are working under the sun with the scorching sun, although sweaty, but the body is very yang, but modern people sit in the empty wither house to eat ice watermelon, occasionally go out to apply sunscreen, umbrellas, lest they be sunburned, so many people who stay in office buildings for a long time are not angry, it is because of these behaviors, therefore, if you take time to bask in the sun every day, you will feel that the whole person has a lot of spirit, which is the power of the sun to us. We just need to follow the rhythm of the sun to arrange our own diet and routine, even if it is health.
