<p>This paper shows that the five elements of the human body exhibit chaotic phenomena and aims to explore the connection and application of the five-element theory of Traditional Chinese Medicine and chaotic systems. To this end, this paper proposes a nonlinear chaotic dynamics model based on the mutual promotion and restraint relationship of the five elements of Traditional Chinese Medicine and deeply analyzes the dynamic interactions between the five elements. Specifically, we measured the bioelectric signals of the 12 meridians of the human body, calculated the corresponding five-element values, and applied them to chaotic model parameter extraction to verify the existence of chaos in the human body. By considering the five elements as “unstable ground states” in the chaotic system, we can reveal the long-term evolution law of the five-element system and found that when the body is in a chaotic state, the health of the human body can be maintained. Simulation and clinical experimental results prove the effectiveness of this method.</p>
