What research or studies have reviewed the effectiveness of weighted blankets?

Weighted blankets are most widely known for their ability to reduce anxiety; however, the uses of weighted blankets extend far beyond basic anxiety disorders. By working on both the parasympathetic and sympathetic systems within the nervous system to calm the body, this “body hug” sensation can provide comfort to those suffering from everything from insomnia to PTSD. A 2006 study from the Occupational Therapy in Mental Health Journal shows that of those tested, “63% reported lower anxiety after use, and 78% preferred the weighted blanket as a calming modality.” To put it simply, weighted blankets provide comfort, calm the senses, and lift our mood.
