I am going to experiment on DH with tart cherry juice!
After a recent study, UK researchers just published in the European Journal of Nutrition that tart cherry juice significantly increased melatonin levels in the body.
“Since melatonin is the hormone that regulates sleep, the team found that people who consumed tart cherry juice concentrate not only slept longer, but also experienced improved quality of sleep.
The team said their findings could have notable benefits for people who have difficulty sleeping due to insomnia, shift work and jet lag.
Co-author Dr. Jason Ellis said: “What makes these findings exciting is that the melatonin contained in tart cherry juice concentrate is sufficient to elicit a healthy sleep response.”
In this small-scale study, researchers recruited 20 healthy volunteers to drink a 30 ml serving of either tart cherry juice or a placebo juice for seven days.
Participants who drank tart cherry juice concentrate for one week were found to have a significant increase in urinary melatonin (+15-16%) against the placebo group.
Actigraphy measurements also registered an increase of about 15 minutes of time spent in bed, an increase of 25 minutes in total sleep time and a five to six percent increase in “sleep efficiency” (a global measurement of sleep quality).
Asked about the significance of the findings, lead author Dr. Glyn Howatson said that little previous research had been done concerning the use of tart cherries. He said: “The data provides strong evidence that sleep can be influenced by the concentrate, and whilst other mechanisms can’t be completely ruled out, we think the melatonin is the principle reason for our observations.”
