Understanding the Biological Rhythm of Tridosha Based on Physiology-A Review

Biological rhythm of Tridoshas has been explained in classical texts. Impact of dosha on various stages of life, day and night and on phases of digestion has been explained as biological rhythm. This dosha predominance in each phase; when analysed is almost synchronous with the neuroendocrine physiology of the body. When one fails to align oneself with this rhythm; doshic equilibrium is lost. This may lead to various illness and decreased life quality. A need to understand and optimize these doshic rhythms is a major building block to health as todays life style is always threatening to uproot this balance at all times. The Search engines on the internet and classical Ayurvedic books were studied using keywords for relevant concepts like biological rhythm, circadian rhythm, sleep wake cycle and ‘prakrithy’.Ayurveda daily regimen terms and their English equivalents as provided in bracket were also screened. Ayurveda has identified the effects of circadian cycles on human health and it advocates sticking to this daily regimen schedule for harmonization of dosha for its perfect functional acumen. How the predominance of dosha is physiologically understood based on hormonal and basic neurology was also screened from journals on physiology. At all levels of preventative domains, incorporating practises into daily life is essential to maintain health. However, to formally validate the same, prospective large-scale, long-term cohort studies are still required.
