Matt delves into the science of weighted blankets for sleep improvement in this week’s episode. These heavy covers (10-40 lbs) utilize Deep Pressure Stimulation (DPS), a concept originating from Dr. Temple Grandin's 1960s work. DPS is theorized to shift the nervous system from "fight-or-flight" to a calmer parasympathetic state by potentially increasing serotonin and activating brain regions involved in emotional regulation, like the insular cortex, thereby fostering a state conducive to sleep. Matt describes research whose highlights include a 2020 study where 42% of insomnia patients achieved remission with weighted blankets, and a 2021 study that showed healthy adults experienced increased deep sleep and less restlessness. Benefits are also noted for children with ADHD. Proposed mechanisms extend to reduced awakenings and anxiety. While studies show promise for specific groups, larger, objective trials are still needed. Weighted blankets (around 10% body weight) are best viewed as a potential aid alongside good sleep hygiene.
