Daily Caffeine Consumption Does Not Influence Acupuncture Analgesia in Healthy Individuals: A Preliminary Study

Animal studies suggest that caffeine may interfere with acupuncture analgesia. This study investigated the modulation effect of daily caffeine intake on acupuncture analgesia in 27 healthy subjects using a crossover design. We found that real acupuncture increased pain thresholds compared to sham acupuncture. Further, there was no association between caffeine intake measurements of daily caffeine use, duration of caffeine consumption, or their interaction and preacupuncture and postacupuncture pain threshold changes. Our findings suggest that daily caffeine intake may not influence acupuncture analgesia in the cohort of healthy subjects who participated in study.
