Comment: Recently someone asked me about weighted blankets and whether they were worthwhile. Not knowing much about them, being a person who likes the air-condition on cold while I sleep with minimal covering I looked around for any information and came across this article in Popular Science, which is based on a systematic review published in the American journal of Occupational Therapy in 2020 – Links at end of post. The general conclusion is Weighted blankets may be an appropriate therapeutic tool in reducing anxiety; however, there is not enough evidence to suggest they are helpful with insomnia.
Kathryn Eron, a mental health researcher at Denver Health Medical Center in Colorado, says that their mental health facilities have been using blankets as an alternative to medication. “Usually the patients that have a higher level of anxiety like [a weighted blanket] and want to use it,” says Ashlie Watters, a researcher at Denver Health specializing in eating disorders. “Anecdotally, they say it is helpful.”
