Weighted items, such as weighted blankets, lap pads, vests, and plush toys, can provide sensory grounding through a mechanism called Deep Pressure Stimulation (DPS). DPS involves applying gentle but firm pressure evenly across the body, similar to a comforting hug. This pressure activates the parasympathetic nervous system, which helps the body enter a state of rest and relaxation. As a result, weighted items can reduce stress, lower heart rate, and calm the nervous system, making them effective tools for sensory regulation[1][2].
The calming effect of weighted items is linked to increased production of neurotransmitters like serotonin and dopamine, which promote feelings of well-being and relaxation. At the same time, DPS can reduce cortisol, the stress hormone, which helps improve mood and reduce anxiety symptoms[1]. This makes weighted items particularly useful for people with sensory processing challenges, such as those with autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), or sensory processing disorder (SPD). For example, children with ASD have been shown to sleep better and experience fewer night awakenings when using weighted blankets[2].
Weighted items also provide proprioceptive input, which is sensory information from muscles and joints that helps the brain understand body position and movement. This input can help individuals feel more grounded and focused. In sensory tents or therapy settings, weighted lap pads or blankets are often used alongside other sensory tools like textured objects or compression vests to help children regulate their sensory experiences and emotions[3].
Beyond blankets, weighted plush toys offer similar benefits by providing comforting pressure that can ease anxiety and improve focus. These weighted plush items are often used in occupational therapy and sensory playgroups to help children and adults manage stress and sensory overload[4][5]. They are especially helpful because they provide a calming effect without fully covering the body, making them suitable for various situations.
In summary, weighted items provide sensory grounding by delivering deep, calming pressure that helps regulate the nervous system, reduce anxiety, and improve sensory processing. This makes them valuable tools for individuals who benefit from sensory input to feel more secure and focused.
