Weighted blankets are the trendiest way to help poor sleepers get a good night's rest. They were first introduced by occupational therapists as treatment for behavioral disorders, but how exactly do weighted blankets work? The idea is that the pressure from the blanket can increase serotonin, a chemical in your body that makes you feel happy and calm. Experts refer to it as "deep-pressure therapy." It's not intended to cure any medical conditions, but it’s become a popular way for anxiety-suffers, insomniacs, and self-proclaimed "bad sleepers" to get some shut eye. Before we get into our top picks, it's important to note that these blankets shouldn’t be used by anyone that can’t move freely beneath the weight. Though they’re sometimes used as a therapeutic means for children, it’s important to speak with their pediatricians first. Another thing you should know about weighted blankets: They’re pricier than regular throw blankets — most range from $100 to $200.
