What is Deep Pressure Stimulation? The Complete Guide

Deep pressure stimulation (DPS) — also known as deep pressure therapy (DPT) or deep touch pressure — is a type of tactile sensory input that involves applying firm, gentle pressure to the body. Think of the calming feeling of a tight hug, a weighted blanket, or a compression vest.

Research shows this type of input activates the parasympathetic nervous system, helping to reduce anxiety, improve focus, and promote relaxation. It’s used widely in occupational therapy for individuals with autism, ADHD, anxiety disorders, and sensory processing challenges.

How Does Deep Pressure Stimulation Work?

Deep pressure stimulation works by activating mechanoreceptors in the skin — specialized nerve endings that detect pressure and touch. When these receptors are stimulated with firm, distributed pressure, they send signals through the nervous system that trigger several physiological responses:

Parasympathetic activation: The “rest and digest” branch of the autonomic nervous system is stimulated, reducing heart rate and blood pressure.
Cortisol reduction: Studies have shown that deep pressure can lower cortisol (the stress hormone) by up to 31%.
Serotonin and dopamine release: These “feel-good” neurotransmitters increase, promoting feelings of calm and well-being.
Melatonin production: The increase in serotonin also supports melatonin synthesis, which aids sleep.

“Deep pressure touch has been shown to have a calming, organizing effect on the nervous system, similar to swaddling an infant.” — Dr. Temple Grandin, Animal Science Professor & Autism Advocate

Who Benefits from Deep Pressure Therapy?

Deep pressure stimulation isn’t just for one specific condition — it benefits a wide range of people:

Autism Spectrum Disorder (ASD)

Children and adults with autism often experience sensory processing differences. Deep pressure helps regulate sensory input and can reduce meltdowns, improve focus during tasks, and promote calmer transitions between activities.

Anxiety Disorders

For people with generalized anxiety, panic disorder, or PTSD, deep pressure provides a non-pharmaceutical tool for managing symptoms. The physiological calming response can interrupt the anxiety cycle.

ADHD

Deep pressure input can help individuals with ADHD improve focus and reduce restlessness. Many children use weighted lap pads during school to stay attentive.

Sleep Disorders

Insomnia and restless sleep are common complaints that respond well to weighted blankets. The deep pressure mimics the sensation of being held, promoting faster sleep onset and deeper sleep cycles.

Sensory Processing Disorder (SPD)

Individuals who are sensory-seeking often crave deep pressure input as a way to feel grounded and organized.

Types of Deep Pressure Stimulation Tools

Weighted Blankets

The most popular DPS tool. Weighted blankets typically weigh between 5–30 lbs and use glass beads or plastic pellets to provide distributed pressure across the body.

Pros

Easy to use — just drape it over your body
Widely available in many sizes and weights
Can be used during sleep or relaxation
No prescription needed
Many affordable options available

Cons

Can be too warm for hot sleepers
Not portable — best for home use
May be too heavy for very young children
Quality varies significantly by brand

Compression Clothing

Compression vests, shirts, and shorts apply consistent pressure throughout the day. These are particularly useful for children in school settings.

Weighted Lap Pads

Smaller weighted items designed to sit on the lap during seated activities. Great for school or office use.

Body Socks

Stretchy, full-body garments that provide proprioceptive input through resistance. Popular with children for sensory play.

Manual Techniques

Occupational therapists use techniques like the Wilbarger Protocol (therapeutic brushing) and joint compressions to provide deep pressure input.

The Science Behind DPS

Multiple peer-reviewed studies support the effectiveness of deep pressure stimulation:

Mullen et al. (2008) found that weighted blankets reduced anxiety by 33% in psychiatric inpatients.
Gringras et al. (2014) demonstrated improved sleep quality and reduced movement during sleep with weighted blankets.
Chen et al. (2011) showed that dental patients wearing weighted vests during procedures had significantly lower anxiety scores.
Reynolds et al. (2015) found that weighted vests improved in-seat behavior and attention in children with ADHD.

How to Choose the Right Weight

The general rule of thumb is:

For blankets: 10% of body weight + 1-2 lbs
For children: Always consult an occupational therapist
For lap pads: 5-10% of body weight
For compression: Snug but not restrictive

Important safety note: Weighted blankets should NOT be used for infants, children under 2, or anyone who cannot remove the blanket independently.

Getting Started with Deep Pressure Therapy

If you’re new to deep pressure stimulation, here’s a practical starting guide:

Identify your goal — Is it better sleep? Reduced anxiety? Improved focus?
Choose your tool — Weighted blanket for sleep, compression vest for daily use, lap pad for work/school.
Start light — Begin with a lighter weight and gradually increase as comfortable.
Be consistent — Use your DPS tool regularly for best results. Many people notice benefits within the first week.
Consult a professional — If you have a specific condition, work with an occupational therapist to create a sensory diet.

Frequently Asked Questions

Is deep pressure stimulation safe?

Yes, deep pressure stimulation is generally safe for most people when used correctly. However, it should not be used on infants, children under 2, or individuals who cannot remove weighted items independently. People with respiratory conditions, circulatory issues, or certain musculoskeletal disorders should consult a healthcare provider first.

How long does it take for deep pressure therapy to work?

Many people feel immediate calming effects within 5-15 minutes of applying deep pressure. For sleep benefits, most users report improvements within the first week of consistent use. Long-term nervous system regulation benefits may take 2-4 weeks of regular use.

Can I use a weighted blanket all night?

Yes, healthy adults and older children can safely use weighted blankets throughout the night. Choose a weight that's approximately 10% of your body weight. If at any point you feel uncomfortable, restricted, or overheated, remove the blanket.

Is deep pressure therapy evidence-based?

Yes. Multiple peer-reviewed studies have demonstrated the physiological effects of deep pressure, including reduced cortisol levels, increased serotonin and dopamine, and activation of the parasympathetic nervous system. Research from institutions including NCBI and various occupational therapy journals supports its use for anxiety, autism, ADHD, and sleep disorders.

What's the difference between deep pressure stimulation and compression therapy?

Deep pressure stimulation is a broader term for any firm, distributed pressure applied to the body (weighted blankets, hugging, squeezing). Compression therapy specifically refers to garments that apply consistent pressure, such as compression vests, shirts, or wraps. Compression therapy is a subset of deep pressure stimulation.
