The Washington Post (12/6, Kim) reports, “The use of a weighted blanket may result in” the release of “more melatonin – a sleep-promoting hormone produced by the brain,” researchers concluded. For the study, “26 young men and women with no sleep problems or other medical conditions were asked to sleep in the laboratory with a weighted blanket one night and a light blanket another night.” Saliva samples revealed that “on average, the rise in melatonin was 32 percent greater on the night the participants slept with a weighted blanket.” The findings were published online in the Journal of Sleep Research.
