The human body and nature are the same, emphasizing the unity of heaven and humanity. Human beings live in the natural world and are closely related and inseparable from nature. The physiological activities of the human body and changes in the natural environment are interdependent, and the human body can adapt to changes in the natural environment for self-regulation and adaptation. At the same time, the human body also operates according to natural laws, such as the internal biological clock and metabolism, which are in line with natural laws.
人体与自然是相同的，讲究天人合一。人类生活在自然界中，与自然息息相关，不可分割。人体的生理活动和自然环境的变化是相互影响的，人体能够适应自然环境的变化来进行自我调节和适应。同时，人体内部也有着自然规律的运行，如人体内部的生物钟、代谢等都与自然规律相符合。
