Tart Cherry Juice May Help Insomniacs

November 2010

Daily consumption of tart cherry juice may help reduce the severity of insomnia as well as time spent awake after going to sleep, according to a study published in the Journal of Medicinal Food.

The randomized, double-blind, crossover study involved 15 older adults with chronic insomnia. Subjects drank eight ounces of tart cherry juice every morning and night, daily, for two weeks, followed by a two-week washout period.

Sleep continuity (sleep onset, wake after sleep onset, total sleep time and sleep efficiency) was assessed by two-week mean values from daily sleep diaries and disease severity by the Insomnia Severity Index.

The researchers said: "The tart cherry juice beverage was associated with statistically significant pre- to post-treatment improvements on all sleep variables. When compared to placebo, the study beverage produced significant reductions in insomnia severity (minutes awake after sleep onset)."
