There are changes in the five movements and six qi between heaven and earth, which are interrelated with the functions of human organs. Traditionally, we view humans and nature as an organic whole, that is, the unity of heaven and humanity. This concept has been widely applied in ancient medical works.
The six gas epidemics and climate change in nature have specific patterns, and their operation in the natural world is bound to have an impact on the human body. When the human body cannot adapt to this impact, it can lead to the occurrence of diseases. This point has been discussed in ancient medical works such as "Su Wen", "Nan Jing", "Mai Jue", etc.
天地之间存在着五运六气的变化，这种变化规律与人的五脏六腑功能相互关联，传统上我们把人和自然看作是一个有机整体，即“天人合一”。这种理念在古代医学著作中得到了广泛应用。

自然界中的六气流行和气候变化有其特定的规律，这些规律在自然世界中的运行，也势必会对人体产生影响。当人体不能适应这种影响时，就会导致疾病的产生。这一点在古代医学著作中如《素问》、《难经》、《脉诀》等都有相关论述。
