A study entitled, ”Effects of homeopathic medicines on polysomnographic sleep of young adults with histories of coffee-related insomnia” has shown that homeopathic remedies have an impact on sleep using technical polysomnographic recordings. It was a placebo controlled study.
The study showed that a homeopathic remedy unlike the placebo “significantly increased PSG total sleep time and NREM, as well as awakenings and stage changes” in those participating in the study.
The study was run by faculty members of the Department of Family and Community Medicine, Department of Psychiatry, Department of Psychology, Mel and Enid Zuckerman College of Public Health, Division of Family Studies and Human Development and the College of Nursing and Health Innovation at The University of Arizona College of Medicine, Tucson, AZ, USA and the Office of World Health Promotion & Disease Prevention, Arizona State University, Tempe, AZ, USA.
Verum remedies [real homeopathic remedies and not the placebo] significantly increased PSG total sleep time and NREM, as well as awakenings and stage changes. Changes in actigraphic and self-rated scale effects were not significant.
The study demonstrated the feasibility of using in-home, all-night sleep recordings to study homeopathic remedy effects. Findings are similar though not identical to those reported in animals with the same remedies. Possible mechanisms include initial disruption of the nonlinear dynamics of sleep patterns by the verum remedies.
