Exploring Caffeine Withdrawal Insomnia Using Insomnia Severity Index (Isi) Method: An Observational Study in Indian Rural Population

Abstract

Purpose

The aim of this study was to assess the physical and mental changes in individuals from a rural Indian population before and after caffeine withdrawal. This study focuses on the behavioral effects, especially insomnia, after caffeine deprivation among participants consuming high levels of caffeine daily.

Methods

An observational cross-sectional study was conducted over a two-month period among 68 volunteers at Sanjivani Rural Education Society, Maharashtra, India. Participants were selected based on their daily caffeine intake, with inclusion criteria focusing on individuals consuming more than 400 mg of caffeine per day. Data on demographics and caffeine consumption were collected using a structured questionnaire. The Insomnia Severity Index (ISI) was used to assess changes in sleep patterns before and after 72 hours of caffeine withdrawal. A multiple correlation method was applied to analyze the relationship between caffeine intake and insomnia severity.

Result

Out of 68 participants, 84% (n=59) reported sleep disturbances during the caffeine withdrawal period, which was classified as substance-induced insomnia according to DSM-IV criteria. A multiple correlation analysis indicated a mild positive association (R=0.22) between high caffeine consumption and the severity of insomnia during withdrawal. These findings suggest that excessive caffeine intake significantly affects sleep quality, particularly during withdrawal periods.

Conclusion

The study identified a notable impact of high caffeine intake on sleep disturbances in a rural Indian population. The results emphasize the importance of moderating daily caffeine consumption to prevent insomnia and improve sleep hygiene. Individualized recommendations for daily caffeine intake are crucial for mitigating potential adverse effects on sleep and overall health.
