The 4 basic principles of constitution

i. e. process theory

body-spirit composition theory

environmental constrain theory and genetic endowment theory are the starting point and theoretical basis of traditional Chinese medicine（TCM） constitution research. From the perspective of the 4 basic principles

this paper summarized the representative empirical research results in recent years and its implications for future research directions. It was proposed that the development of constitution with age showed certain regularity

and it could carry out TCM constitutional intervention for people of different ages to promote the constitutional health management work covering the whole life process. The physiological status of human population quality was mutually affected its psychological state. When interfering with constitution regulation

it is necessary not only to intervene in the physiological state of the unbalanced constitution

but also to pay attention to the psychological adjustment of the unbalanced constitution. The geographical environment

diet composition

living habits

etc. can all have certain constraints to the constitution. When carrying out constitutional intervention

we must focus on improving their behavioral lifestyle

and conditioning from diet

exercise

sleep

etc.

to promote the neutral constitution. The influence of congenital genetic factors on constitution is relatively stable and relatively difficult to change

but by means of encouraging breastfeeding and encouraging childbearing at an appropriate age

it also can improve the health of the body to a certain extent.
