The blanket is filled with 95% glass beads and 5% polyester fibres, which are divided into cassettes that ensure an even distribution of the weight. The weighted blanket should weigh around 7-12% of your body weight. Therefore, this duvet is only recommended for adults. The thin duvet provides deep, sensory-stimulating pressure which contributes to the production of melatonin. Melatonin is a natural hormone that can help you fall asleep faster. It is also called the "Sleep hormone". The pressure from the duvet reduces cortisol, which is the body's most important stress hormone. You'll sleep deeper and better, and wake up more rested the next day. The duvet is a drug-free way to help you with insomnia and alleviates stress and anxiety. The weighted duvet is OEKO-TEX certified, which is your guarantee that the product is free of substances harmful to health.
