Adults, teens, and children seeking sleep and relaxation can benefit from a weighted blanket. Weighted blankets, vests, and scarfs can help those with sensory processing disorders, sleep disorders, insomnia, symptoms of ADD/ADHD, restless leg syndrome, Asperger's and autism spectrum disorder, and any type of anxiety. Behavioral and developmental disorders are on the rise: one in every six children, 1.8 million more than in the 1990's, is diagnosed with a developmental disability, such as autism, ADHD, or learning disabilities, according to research from the Centers for Disease Control and Prevention.
