Effects Of Short-Term Sleep Hygiene Intervention On Fasting Blood Glucose In Pre-Diabetics: A 10-Day Pilot Study

Abstract

Background: Emerging evidence links disturbed sleep patterns with adverse metabolic outcomes, including insulin resistance and prediabetes. In Ayurveda, Nidra (sleep) is regarded as a fundamental pillar of health, vital for physiological balance. Proper sleep routines (Ratri Charya) are believed to optimize metabolic functions and promote overall well-being. Objective: This pilot study aims to evaluate the effects of Ayurvedic sleep hygiene counseling on fasting blood sugar (FBS) levels and sleep quality in pre-diabetic individuals over a span of 10 days. Methods: Ten pre-diabetic adults adhered to a structured 10-day intervention comprising fixed sleep timing, early light dinner, screen reduction, and herbal evening tea. FBS levels and subjective sleep quality scores were measured before and after the intervention. Additionally, a subset of participants reported subjective changes in energy, digestion, and mood. Results: The study observed an average reduction of 4.6 mg/dL in FBS (from 116.2 mg/dL to 111.6 mg/dL), with 100% of participants reporting improved sleep quality. Notably, 80% reported enhanced daytime energy and digestion. The majority also noted decreased evening stress levels. Conclusion: Implementing Ayurvedic sleep hygiene practices can serve as an effective non-pharmacological adjunct for early management of dysglycemia. Longer-term, controlled studies are recommended to validate these preliminary findings. Sleep, or Nidra, holds a central position in Ayurveda, considered one of the three essential pillars of health alongside Ahara (diet) and Vihara (lifestyle). Classical texts such as the Charaka Samhita and Sushruta Samhita emphasize the importance of proper sleep in maintaining physical vitality, mental clarity, and metabolic harmony.
