Deep relaxation caused by the pressure of a Weighted Blanket makes us fall into a deep sleep in a short time without waking up at night. It stimulates your pineal gland to intensify the production of melatonine. The weight duvet also affects the production of Serotonin – the happiness hormone with the simultaneous reduction of cortisol, also known as the stress hormone. When covering ourselves with a Weighted Blanket, we get a pleasant sense of security and tranquility. As the result our body and nervous system calm down.
