Over the thousands of years of observing nature and themselves, some qigong practitioners went even deeper. They realized that the body's qi circulation changes with the seasons and that it is a good idea to help the body out during these periodic adjustments. They noticed also that in each season different organs have characteristic problems. For example, at the beginning of fall, your lungs have to adapt to the colder air you are breathing. While this adjustment is going on, the lungs are susceptible to disturbance, so your lungs may feel uncomfortable and you may catch colds easily.

Your digestive system is also affected during seasonal changes. Your appetite may increase, or you may have diarrhea. When the temperature goes down, your kidneys and bladder will start to give you trouble. For example, because the kidneys are stressed, you may feel pain in your back. Focusing on these seasonal qi disorders, the meditators created a set of movements that can be used to speed up the body's adjustment. These qigong exercises are commonly called "four seasons gong" (si ji gong).
