Circadian Rhythm Disruption and Dinacharya: A Kriya Sharir Perspective on Sleep Disorders in the Digital Era

Abstract

In today’s world, constant exposure to blue light from screens, erratic sleep schedules, and mismatched daily routines have sharply increased circadian rhythm disturbances and sleep disorders such as insomnia. Modern chronobiology points to melatonin suppression through the suprachiasmatic nucleus (SCN) pathway as a central mechanism behind these issues. Ayurveda, through the lens of Kriya Sharir, views these biological rhythms as natural cycles governed by the rhythmic predominance of the three Doshas - Vata, Pitta, and Kapha - in alignment with solar and diurnal time. The classical daily regimen known as Dinacharya offers practical tools to realign these energies and support Ratri Swabhavaprabha, the body’s innate tendency toward restorative sleep. This review brings together current evidence from chronobiology with insights from Ayurvedic texts to show how specific Dinacharya practices- waking during Brahma Muhurta, eating meals at appropriate times, retiring early, and moderating sensory overstimulation- can effectively counteract the disruptive effects of digital-age light exposure. When applied thoughtfully, these routines provide a simple yet holistic strategy for preventing and managing sleep problems in contemporary life. Further well-designed clinical studies are needed to evaluate the impact of integrated Ayurvedic-modern approaches.
