Dosha at physical level originate from five fundamental elements ([[pancha mahabhuta]]). Vata dosha originates from [[vayu]] and [[akasha mahabhuta]]; Pitta dosha from [[agni mahabhuta]] and kapha dosha from combination of [[aap]] and [[prithvi mahabhuta]]. The dosha represent functions of dominant [[mahabhuta]] in the body at gross level. They can be principles of regulators, enhancers or inhibitors of the physiological functions.

===Body constitution or phenotype ([[deha prakriti]])===
   −
The body constitution (prakriti) of a person is based upon the relative proportions of the three dosha. The equilibrium or dominance of dosha at the time of formation of embryo determines the body constitution (deha prakriti). [Cha.Sa. [[Sutra Sthana]] 7/40] This proportion is further modulated by the diet and lifestyle of mother, age, and the environment in which the person grows to generate the unique dosha-prakriti of the individual.  The individual shows characteristic features of respective dominant dosha in prakriti. It is very similar to the phenotype in modern biology. Thus, the current genetic paradigms believe that the phenotype of individual results from interaction between genotype (established at fertilization) and the environment, which includes epigenetic changes resulting from parental age, diet, lifestyle, and other environmental factors.<ref>Lakhotia S. C. (2014). Translating Ayurveda's Dosha-Prakriti into objective parameters. Journal of Ayurveda and integrative medicine, 5(3), 176.</ref>  Genomic variations with the classification of prakriti are studied. It is observed that PGM1 correlates with phenotype of pitta prakriti. This suggests that the phenotypic classification has a genetic basis; and its prakriti-based practice resonates with personalized medicine.<ref>Govindaraj, P. et al. Genome-wide analysis correlates Ayurveda Prakriti. Sci. Rep. 5, 15786; doi: 10.1038/srep15786 (2015)</ref>  The relation between clinical phenotype and predisposition of disease is studied.

The lifestyle activities that produce similar effects as of dosha lead to vitiation of dosha and vice versa.  For example, excess movement increases vata dosha, and rest pacifies vata dosha.  The same principles are applied in treatment of diseases due to vitiation of dosha.

== Natural cycle of dosha as per seasonal variation ([[ritu]] [[kriyakala]])==
    
The body is continuously exposed to the external environment and climatic changes as per season. The dosha tend to deviate from normal state and show variations in their levels according to the seasons. These physiological disequilibrium states are maintained by adopting seasonal dietary and lifestyle regimen ([[ritucharya]]) to preserve health.  As these states are more prone for opportunistic diseases, these are also called as ‘ritu kriyakala’ (seasonal opportunities). The table shows seasonal variations in dosha.

Research studies have suggested the patterns of blood chemistry, genetic expression, physiological states, and chronic diseases are associated with each dosha type. Triglycerides, total cholesterol, high LDL, and low HDL concentrations, common risk factors for cardiovascular diseases were reported to be higher in kapha types as compared to pitta and vata types. Whereas Hemoglobin and RBC count tend to be higher in pitta as compared to other types, while serum prolactin was found to be higher in vata types. Genetic expression also distinguishes dosha types. Where genes in the immune response pathways were up-regulated in pitta types, genes related to cell cycles up-regulated in vata types, and genes in the immune signaling pathways were found to be up-regulated in kapha types.

Also, inflammatory genes were up-regulated in vata types, whereas up-regulation of oxidative stress pathway genes were observed in pitta and kapha types. CD25 (activated B cells) and CD56 (natural killer cells) were higher in kapha dosha types. CYP2C19 genotypes, a family of genes that help in detoxification and metabolism of certain drugs were down-regulated in kapha types and up-regulated in pitta types.  A research program using physiological and cortical measures is suggested to explore the utility of dosha brain-types. Dosha brain models may give scope to learn in field of relation of dosha to electroencephalography EEG patterns, autonomic activation and autonomic balance, stress reactivity and behavior. This line of research could help clarify variable response to drugs and lifestyle modifications in normal and clinical populations and so help target health promotion at all levels of life.

The systems approach proposed by Hankey A. shows how tridosha applies to every living organism from the first cells, and how it is inherited and diversified in the history of life. Ayugenomics study confirms dosha's inheritance.

===Relation of [[vata dosha]] and vagus nerve===

Venil Sumantran and Pratibha Nair proposed strong correlations between vagus nerve and vata dosha activity. They have hypothetically provided four possible reasons to assume vagal activity as a reliable candidate biomarker of important vata dosha functions. First, normal vata dosha and the vagus maintain neural, respiratory, and digestive homeostasis, and dysfunctions in both entities cause very similar diseases.  Second, vata dosha regulates higher neural functions such as mental health and behaviour, and the 'polyvagal theory' proposes similar functions for the vagus. Third, the similar roles of vata dosha and vagus in maintaining gut homeostasis, suggest that vagal activity in the 'gut-brain' link is a candidate biomarker of pakwashaya (lower gut), a primary regulatory site for vata dosha. Fourth, the vagus is the only vital nerve whose activity can be reliably measured and manipulated. Vagal nerve stimulation is an approved therapy for certain ailments attributed to impaired vata dosha.<ref>Venil N Sumantran, Pratibha P Nair. Can the vagus nerve serve as biomarker for vata dosha activity?  J Ayurveda Integr Med, Apr-Jun 2019;10(2):146-151.

A study was conducted to determine if each dosha can act as a predictor of quality and quantity of sleep. The survey-based cross-sectional study carried out on 995 persons of both sexes (average age 49.1 years) suggests that higher vata scores are associated with a longer time to fall asleep and a lesser feeling of being rested in the morning. Higher kapha scores, in contrast, are associated with longer daytime naps. These results suggest tridosha play important role in sleep physiology. The dosha can influence the quality and quantity of sleep.<ref>Telles, S., Pathak, S., Kumar, A., Mishra, P., & Balkrishna, A. (2015). Ayurvedic doshas as predictors of sleep quality.
