A weighted monkey is a plush stuffed animal filled with materials like non-toxic glass beads or polyester to increase its weight. It functions as a sensory support tool, designed to be held or placed on the lap to provide calming input. The added weight is calibrated to offer a form of physical contact that can influence the user’s nervous system and help with emotional regulation.
The Science of Deep Pressure Stimulation
The effect of a weighted monkey comes from Deep Pressure Stimulation (DPS). This is the application of firm but gentle pressure to the body, which feels similar to a comforting hug. This sensation activates the parasympathetic nervous system, responsible for the body’s “rest and digest” functions. The applied weight helps shift the body away from a high-alert “fight or flight” state.
This shift directly impacts brain chemistry. The consistent pressure encourages the release of neurotransmitters like serotonin and dopamine. Serotonin is involved in mood regulation and feelings of calmness, while dopamine is associated with pleasure and a sense of reward. These neurochemical changes help foster feelings of security and relaxation.
Therapeutic Uses and Applications
Weighted monkeys are used to assist individuals with sensory processing disorders, autism spectrum disorder (ASD), and attention-deficit/hyperactivity disorder (ADHD). For these users, the sensory input can aid in self-regulation, reduce restlessness, and improve focus. The physical sensation provides a grounding effect that helps manage sensory-seeking behaviors.
The applications extend beyond developmental conditions, as many people use weighted plush toys to manage anxiety, stress, and sleep-related issues. The calming pressure is helpful during moments of overwhelm or before bedtime to promote relaxation. The monkey serves as a portable source of comfort for use at home, in a classroom, or during therapy sessions.
Safety and Selection Considerations
When choosing a weighted monkey, safety is the primary consideration. These products are not safe for children under three due to the risk of suffocation. Select an appropriate weight, with the guideline being 5-10% of the user’s body weight. Consulting a therapist is recommended to ensure the product is used safely.
The toy’s construction is also important. Seams must be securely stitched to prevent the weighted filler, such as glass beads, from leaking. The outer fabric and inner filling should be non-toxic. Proper care, like spot cleaning instead of machine washing, is required to maintain the item’s integrity.
