These products are all about stimulating the proprioceptive system to either calm or alert an individual. The proprioceptive system relates to information from muscles, joints and ligaments. It gives the brain information about positioning, or where the body is in space.
Weighted blankets are designed to help calm or relax an individual. Those who have difficulties tolerating or registering sensory stimuli may respond positively to heavy touch or pressure. Some individuals find stronger sensations more comfortable and calming. Therapists usually recommend 5-10% of body weight for weighted vests and shoulder weights.
When using weighted products, do not cover the head with them. Weighted products should be used under the guidance of an appropriate professional. Do not exceed the time or weight recommendations. When using weighted products with children, always use under adult supervision.
