Hi
I am from Australia and in my experince it is the best blanket you can have it is worth every penny It is made in such a way that it helps to ease stress and increase calmness and made you feel relaxed.
but still studies on the use of weighted blankets are limited.
When you hug some one so feelings are great so same the weighted blanket works it gives deep pressure that could have an impact on the central nervous system, calming a child who was over-aroused or overactive.
I have used weighted Blanket and got guidence and still from my point of view it is worth it
