The "indifference to nothingness" and "idleness and lack of desire" in Huangdi Neijing mainly reflect the mental health elements among the six elements of health. These mentalities contribute to mental health and reduce stress and anxiety. By pursuing inner peace and tranquility and maintaining a relaxed and satisfied attitude, people can cultivate a good attitude and maintain mental health. This view was demonstrated and expounded in Huangdi Neijing, which mentioned the positive influence of indifference and nothingness and leisure on mental health. This pursuit and maintenance of mental health is of great significance to the overall health and happiness of individuals.
