What Is a Weighted Blanket?

A weighted blanket is a therapeutic blanket designed to be noticeably heavier than a regular comforter, typically weighing between 5 and 30 pounds.

There are two main styles:

  • Duvet style weighted blankets get their weight from small fillers, plastic poly pellets, micro glass beads, or steel shot beads sewn into evenly distributed compartments so the weight stays balanced across your body.
  • Knitted weighted blankets skip the fillers entirely. They're hand knit from chunky, bulky yarn, which creates weight naturally while staying breathable and quiet.


Weighted blankets were originally developed as therapeutic tools for people on the autism spectrum, people living with dementia, and people managing mental health conditions. Since first becoming commercially available in the 1990s, they've crossed over into the mainstream as a sleep aid, popular with anyone who deals with stress, anxiety, or restless nights.

How Do Weighted Blankets Work?

A weighted blanket simulates a therapeutic technique called deep pressure stimulation (DPS), sometimes called deep pressure therapy. DPS involves applying firm but gentle, consistent pressure across the body to promote feelings of calm. You experience it whenever you're hugged, swaddled, or wrapped tightly, and it's the same effect produced by tools like weighted vests.

The nervous system connection

Your autonomic nervous system manages the body's automatic processes circulation, digestion, breathing, and heart rate. It has two branches:

  • The sympathetic nervous system takes over when you're under stress. Your adrenal glands release stress hormones, your heart rate climbs, and your blood pressure rises. This is "fight or flight."
  • The parasympathetic nervous system takes over when your body feels safe. Heart rate slows, blood pressure drops, and your body shifts into rest-and-digest mode.


A 2015 study in the American Journal of Occupational Therapy found that deep pressure stimulation from a weighted vest suppressed sympathetic activity and activated the parasympathetic nervous system, triggering the body's physiological relaxation response. A weighted blanket works the same way: by distributing gentle, constant pressure evenly across your body, it nudges your nervous system out of stress mode and into relaxation mode.

Can You Sleep With a Weighted Blanket?

Yes and for many people, sleeping under one is the whole point.

A 2020 study published in the Journal of Clinical Sleep Medicine found that sleeping with a weighted blanket may improve both sleep duration and sleep quality, especially for people with insomnia tied to anxiety or stress.

How much should a weighted blanket weigh?

Most manufacturers recommend a weighted blanket that's approximately 10% of your body weight. This rule of thumb keeps the blanket heavy enough to deliver real deep pressure stimulation without feeling restrictive.

Your body weight Recommended blanket weight
100 lb (45 kg) 10 lb
130 lb (59 kg) 13 lb
150 lb (68 kg) 15 lb
180 lb (82 kg) 18 lb
200 lb (91 kg) 20 lb
230 lb+ (104 kg+) 23–25 lb

If you sleep with a partner under the same blanket, base the weight on the lighter person or buy two separate blankets.

Hot sleeper or cold sleeper?

Filler material matters more than most shoppers realize:

  • Sleep warm? Look for glass beads. They're dense and small, which means a thinner, more breathable blanket. The Canadian designed knitted weighted blanket category (like our HUSH Cotton Knit Weighted Blanket) is built for hot sleepers. The open knit structure lets air pass through instead of trapping body heat.
  • Sleep cold? Plastic poly pellets retain more heat and feel more "duvet like." They can also be slightly noisier when they shift around.


If you run hot under any blanket, pairing a knitted weighted blanket with breathable bedding like our HUSH Iced 2.0 Cooling Sheet & Pillowcase Set keeps your whole sleep surface cool.

Do Weighted Blankets Reduce Stress?

Stress and sleep are tightly linked and not in a good way. Stress makes it harder to fall asleep, and sleep loss makes you more reactive to stress. When you're sleep deprived, your body produces more cortisol (the primary stress hormone), which then keeps you more wired the next night. It's a loop, and it's hard to break from inside.

This is where weighted blankets earn their reputation. Using one before bed or while you're winding down on the couch can:

  • Lower your heart rate as your parasympathetic nervous system kicks in
  • Reduce pre-sleep anxiety, making it easier to drift off
  • Minimize tossing and turning during the night, which means fewer mid-sleep awakenings


For Canadians dealing with shorter winter days, seasonal affective disorder can also disrupt sleep and a weighted blanket can be a useful piece of a broader wind-down routine.

Do Weighted Blankets Help You Sleep? What the Research Says

The short answer: probably yes, especially if your sleep problems are tied to anxiety, stress, or restlessness.

The melatonin connection

Melatonin is the hormone your brain releases in response to darkness. It's produced primarily by the pineal gland, an endocrine structure deep inside the brain, on a signal from the suprachiasmatic nucleus your body's master circadian clock in the hypothalamus. As melatonin rises in the evening, your body begins to prepare for sleep.

A small but striking 2023 study measured pre-sleep salivary melatonin in young, healthy adults. When participants used a weighted blanket, their melatonin levels in the hour before bedtime were approximately 32% higher than when they used a light blanket.

Melatonin isn't strictly required for sleep, plenty of people sleep fine with low levels but it primes your body for rest. A natural way to nudge it upward is a meaningful win.

Self-reported sleep improvements

A separate study of 28 adults with chronic difficulty falling and staying asleep tracked them across six weeks of weighted-blanket use. Participants reported improvements in:

  • Overall sleep quality
  • Staying asleep through the night
  • Falling asleep faster


These aren't randomized clinical-trial results, but the pattern is consistent across multiple studies: weighted blankets don't cure insomnia, but they meaningfully nudge the dial for a lot of people.

Are Weighted Blankets Safe for Everyone?

No and this part matters.

Weighted blankets are generally safe for healthy adults, but they're not for everyone. Talk to your doctor before using one if you have any of these conditions:

  • Sleep apnea extra weight on the chest can make breathing harder. If you've been diagnosed with sleep apnea, your CPAP machine should be your first line of treatment; a weighted blanket is at best an add-on, and not without medical guidance. Browse our full range of CPAP machines and sleep apnea treatments.
  • Asthma or other respiratory conditions
  • Low blood pressure
  • Type 2 diabetes
  • Circulatory conditions
  • Claustrophobia - the wrapped sensation isn't relaxing for everyone

Who should avoid weighted blankets entirely

  • Infants and toddlers. A weighted blanket is a suffocation risk for young children, full stop.
  • Older children with breathing problems, heart conditions, epilepsy, circulation problems, or skin allergies.
  • Any adult or child who can't physically remove the blanket on their own. This is the most important safety rule.


If you're unsure whether a weighted blanket is right for someone in your home, ask their physician first. For tips on safer sleep tools for kids, see our guide on helping children sleep better.

How to Choose the Right Weighted Blanket

Use this quick checklist when you're shopping:

  1. Weight — aim for ~10% of your body weight
  2. Filler vs. knit — glass beads or knitted for hot sleepers, poly pellets for cold sleepers
  3. Size — match it to your body, not your mattress. A weighted blanket should drape over you, not hang off the bed
  4. Material — breathable cotton or bamboo for year-round use
  5. Washability — knitted designs (like the HUSH Cotton Knit) are typically machine washable; bead-filled blankets often need a removable duvet cover
  6. Trial period — give yourself at least 2–3 weeks to adjust before deciding whether it works

The Bottom Line

Research into weighted blankets is still developing, but the existing evidence is consistent: they can help reduce stress and anxiety, support relaxation, and improve sleep quality for many people. They're not a medical treatment, but as a non-pharmaceutical tool to help your nervous system wind down, they're hard to beat.

If you've ruled out underlying issues like sleep apnea and your doctor has cleared you a weighted blanket sized to your body is one of the simplest sleep upgrades you can make.

Frequently Asked Questions

How heavy should a weighted blanket be?

Roughly 10% of your body weight. A 150 lb adult should look for a 15 lb blanket; a 200 lb adult should look for a 20 lb blanket.

Can you sleep with a weighted blanket every night?

Yes, most healthy adults can use one nightly. If you have sleep apnea, asthma, low blood pressure, or any chronic condition, talk to your doctor first.

Do weighted blankets really improve sleep?

Research suggests they can. Studies have shown improvements in self-reported sleep quality, faster sleep onset, and pre-sleep melatonin levels up to 32% higher than with a light blanket.

Are weighted blankets safe for children?

Not for infants or toddlers. Older children should only use one if they can remove it themselves and don't have breathing, heart, circulation, epilepsy, or skin allergy concerns. Always check with a pediatrician first.

Do weighted blankets make you hot?

They can, depending on the filler. Knitted weighted blankets and those filled with glass beads tend to sleep cooler. Plastic poly pellet blankets retain more heat.
