Cherry Juice May Improve Insomnia
July 12/Lansing, Mich./PRNewswire -- Drinking tart cherry juice daily could help reduce the severity of insomnia and time spent awake after going to sleep, according to a new study published in the Journal of Medicinal Food.
A team of University of Pennsylvania, University of Rochester and VA Center of Canandaigua researchers conducted a pilot study on the sleep habits of 15 older adults. The adults drank 8oz of tart cherry juice beverage in the morning and evening for two weeks, and a comparable matched juice drink, with no tart cherry juice, for another two-week period. There were significant reductions in reported insomnia severity and the adults saved about 17 minutes of wake time after going to sleep, on average, when drinking cherry juice daily, compared to when they were drinking the juice drink.
Ongoing sleep issues plague more than 40 million adults and another 20 million experience occasional sleep disruptions, putting their health and wellbeing at risk, and leaving many Americans on a quest for sleep solutions, according to the National Institutes of Health. Americans spend more than $84 million on over-the-counter sleep aids each year.
The researchers suspect tart cherries' natural benefits could be due in part to their relatively high content of melatonin -- a natural antioxidant in cherries with established ability to help moderate the body's sleep-wake cycle. Produced naturally by the body in small amounts, melatonin plays a role in inducing sleepiness at night and wakefulness during the day.
Russel J. Reiter, Ph.D, a biomedical scientist at the University of Texas Health Science Center and one of the world's leading authorities on melatonin, says while melatonin supplement pills have been heavily promoted as a sleep aid, foods such as cherries -- available year-round as dried, frozen and juice -- may be a better alternative for boosting the body's own supply of melatonin.
"When consumed regularly, tart cherries may help regulate the body's natural sleep cycle and increase sleep efficiency, including decreasing the time it takes to fall asleep," says Reiter. "And, because cherries are so rich in other antioxidants, such as anthocyanins, you get other important health benefits."
