If you are an insomniac or suffer from PTSD or similar types of anxiety, you may want to know about weighted blankets. These blankets have been used for decades in therapy for kids with developmental disorders and for anxious animals. But now they are becoming more popular for people as well.
A study in Sweden in 2015 found that a weighted blanket improved sleep quality for insomniacs by providing the feeling of being cocooned. The pressure stimulation has been shown to reduce cortisol and increase serotonin and melatonin in the brain, all of which can help with sleep.
While more research needs to be done, the findings so far are promising. In 2008, a study was done at the University of Massachusetts, Amherst with 32 participants and a 30 pound weighted blanket. They found that 63% of the participants reported lower anxiety after using it.
Certainly, it seems like something worth looking into if you suffer from an inability to get to sleep, or to stay asleep through the night.
