Quick answer: Deep pressure therapy uses firm, evenly distributed pressure — through weight or compression — to calm the nervous system. Weighted products (like blankets and vests) apply pressure through added mass, while compression products (like vests and body socks) apply pressure through snug, stretch-fabric fit. Both work toward the same goal, but they suit different situations, ages, and sensory needs.
If you've spent any time researching sensory tools for a child with autism, ADHD, or sensory processing disorder (SPD), you've probably run into the term "deep pressure therapy" — and probably also run into two products that both claim to deliver it: weighted items and compression items. They're often talked about interchangeably, but they work differently, and picking the right one (or the right combination) can make a real difference.
What Deep Pressure Therapy Actually Does
Deep pressure stimulation is a firm, gentle pressure applied across the body — think of the feeling of a firm hug, or being tucked tightly into bed. For many kids with autism, ADHD, or SPD, this kind of input helps regulate the nervous system: it can lower cortisol (a stress hormone), increase serotonin and dopamine, and shift the body out of "fight or flight" mode. That's why deep pressure is such a common recommendation from occupational therapists working with sensory-sensitive kids.
The therapy itself isn't new — it's the same principle behind swaddling infants, weighted lap pads used in classrooms, and the "squeeze machine" popularized by Temple Grandin. What's changed is how many product formats now deliver it.
Weighted Products: Pressure Through Mass
Weighted products use evenly distributed internal fill (usually poly pellets or glass beads) to add gentle, constant weight across the body.
Common formats: weighted blankets, weighted vests, weighted lap pads
Best for:
- Bedtime and sleep support — a weighted blanket is one of the most common tools parents reach for first
- Calming during transitions, meltdowns, or overstimulating environments
- Kids who respond well to sustained, "grounding" pressure rather than pressure that moves with them
Things to know: Weight recommendations generally follow a 10% of body weight guideline (though always check the specific product and consult your child's OT or pediatrician). Weighted items are usually stationary-use — a weighted blanket works best when your child is sitting, resting, or sleeping, not running around.
Compression Products: Pressure Through Fit
Compression products use snug, stretchy fabric to apply consistent pressure across the body as the child moves — more like a firm hug that stays with them.
Common formats: compression vests, compression/body socks, sensory swings, compression clothing
Best for:
- Active or school hours, since compression moves with the child rather than requiring them to sit still
- Kids who need proprioceptive input (body awareness) throughout the day, not just during calm-down time
- Situations where a weighted item would be impractical — the classroom, the car, outdoor play
Things to know: Compression garments are typically sized by body measurements rather than weight, and many are designed to be worn under regular clothing, which makes them more discreet for school-age kids who don't want a visible sensory tool.
Weighted vs. Compression: Side-by-Side
| Weighted | Compression | |
|---|---|---|
| How it works | Added mass creates downward pressure | Snug fit creates all-over pressure |
| Best setting | Resting, bedtime, calm-down corner | Active hours, school, car rides |
| Movement | Stationary use | Moves with the child |
| Sizing | By body weight | By body measurements |
| Discreetness | Visible (blanket, vest) | Can be worn under clothes |
Do You Have to Choose One?
Not necessarily. Many families use both — a weighted compression vest actually combines the two approaches into a single product, and it's common to see a weighted blanket used at bedtime alongside a compression vest during the school day. Since every child's sensory profile is different, it often comes down to trial and observation: does your child seek out tight spaces and hugs (a sign compression may help), or do they calm down under a heavy blanket at bedtime (a sign weight may help)? Many occupational therapists recommend starting with whichever matches your child's existing self-regulating behaviors.
Frequently Asked Questions
Is deep pressure therapy safe for kids with autism? Yes, for most children — deep pressure stimulation is widely used in occupational therapy and considered low-risk. That said, always follow weight guidelines for weighted products, supervise use with younger children, and check with your child's OT or pediatrician if they have any respiratory, circulatory, or mobility conditions.
What age can a child start using weighted or compression products? Weighted blankets are generally recommended for children over 2 years old who can move the blanket off themselves independently. Compression garments can often be introduced earlier since there's no added weight, but sizing and supervision still matter — check the specific product's age recommendation.
How do I know if my child needs deep pressure input? Common signs include seeking out tight spaces, asking for tight hugs, wrapping themselves in blankets, appearing calmer after physical activity, or showing signs of sensory overload (meltdowns, covering ears, avoiding touch) that ease with firm pressure.
Can deep pressure products replace occupational therapy? No — they're a supportive tool, not a replacement for professional OT guidance. If you're unsure what your child needs, an occupational therapist can assess their specific sensory profile and recommend the right approach.
