Effects of homeopathic medicines on polysomnographic sleep of young adults with histories of coffee-related insomnia.
BACKGROUND Homeopathy , a common form of alternative medicine worldwide , relies on subjective patient reports for diagnosis and treatment . Polysomnography offers a modern methodology for evaluating the objective effects of taking homeopathic remedies that clinicians cl aim exert effects on sleep quality in susceptible individuals . Animal studies have previously shown changes in non rapid eye movement sleep with certain homeopathic remedies . METHODS Young adults of both sexes ( ages 18 - 31 ) with above-average scores on st and ardized personality scales for either cynical hostility or anxiety sensitivity ( but not both ) and a history of coffee-induced insomnia participated in the month-long study . At-home polysomnographic recordings were obtained on successive pairs of nights once per week for a total of eight recordings ( nights 1 , 2 , 8 , 9 , 15 , 16 , 22 , 23 ) . Subjects ( N=54 ) received placebo pellets on night 8 ( single-blind ) and verum pellets on night 22 ( double-blind ) in 30c doses of one of two homeopathic remedies , Nux Vomica or Coffea Cruda . Subjects completed daily morning sleep diaries and weekly Pittsburgh sleep quality index scales , as well as profile of mood states scales at bedtime on polysomnography nights . RESULTS Verum remedies 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 . CONCLUSIONS 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
