Interplay of Fasting, Circadian Rhythms, and Ayurvedic Langhan: An Integrative Perspective

This article explores the convergence of ancient Ayurvedic principles and modern chronobiology, focusing on fasting and the concept of Langhan. Ayurveda, the traditional Indian system of medicine, emphasizes the balance of three fundamental doshas (Vata, Pitta, Kapha) and their cyclical dominance throughout the day (doshakala). Contemporary science recognizes the biological clock (circadian rhythm) as a critical regulator of physiological processes. Fasting, particularly time-restricted eating, has gained attention for its health benefits, which align with both circadian biology and Ayurvedic Langhan. Langhan, a therapeutic lightening method, is prescribed to restore dosha equilibrium and is traditionally timed according to doshakala. This article examines the scientific basis of fasting in relation to circadian rhythms and its parallels with Langhan, proposing an integrative approach for health optimization.
