Based on the Theory of"Four Seasons In a Day"in Huangdi Neijing,a Discussion on the Imbalance of Circadian Rhythm Impact of Thyroid Disease
The theory of"four seasons in a day"in Huangdi Neijing embodies the changes of the four phenomena:sprouting in spring,growth in summer,ripening in autumn,and storage in winter,within the physiological laws of the human body during a day.This theory is highly consistent with the circadian rhythm theory for the human body's daily changes.The disruption of circadian rhythm results in yin-yang disharmony and impaired circulation of qi and blood,contributing significantly to the recur-rence of thyroid disorders.Based on the theory of"four seasons in a day,"this paper explores how imbalanced circadian rhythms can contribute to recurrent thyroid diseases.It is believed that the waxing and waning of yin and yang in the human body are con-nected to changes in various negative feedback regulations within the circadian rhythm.This interoperability is predominantly demonstrated through the body's self-regulation over time,which represents a vital factor affecting the development of thyroid disease.The disruption of circadian rhythm impedes the movement of the body's Defensive Qi,resulting in blockages of internal organs and meridians,thus compromising the functioning of the human body's"Sprouting,Growth,Ripening,and Storage".No-tably,from 11p.m.to 3 a.m.,Qi and blood predominantly course through the Hepatobiliary Channel.Drawing on the"four seasons in a day"theory,this underscores the theoretical grounding in leveraging liver-focused clinical interventions for treating thyroid diseases.
