There is a wealth of research on both weighted blankets and the technique behind "Deep Pressure Touch Stimulation" (DPTS), which is known in Danish as "dyb søkke stykke stimulering". Here we have highlighted some of the studies that conclude the positive effect of weighted blankets on people.
Swedish sleep researcher Gaby Badre researched the use of weighted blankets with the aim of reducing insomnia. In this study, it was generally concluded that a weighted blanket had a positive effect on the participants' sleep. The participants particularly experienced that they found it easier to calm down and the study indicates that everyone had a sleep with less movement and more relaxation. (Source)
A master's thesis from Denmark concluded evidence for the effect of ball blankets in children with sensory integration problems. The study concludes that a ball blanket can contribute to a better night's sleep, mood and concentration. (Source)
In 2010, a study was published on the use of ball pillows to treat sleep problems. The study concluded that the use of ball pillows is highly relevant and effective, especially when it comes to falling asleep faster. In children with ADHD, the study concluded that the 20% of participants who previously had to spend over 30 minutes falling asleep were reduced to 0%. This means that all children with ADHD fell asleep in less than 30 minutes, simply by using a ball pillow. (Source)
A 2008 study investigated the therapeutic effect of deep tactile pressure stimulation through the use of a weighted blanket. The study found that of the 32 adult participants, 33% had less EDA when using it, 63% experienced less anxiety when using it, and 78% preferred the weighted blanket as a means of calming down.(Source)
