Promoted as solutions for anxiety and sleeplessness, weighted blankets have gained popularity, thanks in part to endorsements from celebrities and influencers touting their calming benefits. These heavy throws, filled with glass beads or plastic pellets, have transitioned from niche therapeutic items to essential wellness tools, claiming to enhance sleep and lower stress for those who find it hard to relax.
But, do they actually fulfill these claims, or are we just paying a premium for what might be an expensive placebo effect?
Occupational therapists have employed weighted blankets since the 1970s to support children with autism and adults with sensory processing disorders. While they became commercially available in the 1990s, their usage primarily remained within special needs circles.
However, recent years have seen a shift, as companies began marketing to what they refer to as the “casually anxious” – basically, anyone grappling with the pressures of modern life. The strategy proved effective; Time magazine even recognized the weighted blanket as one of the top 50 “inventions” of 2018.
The appeal of weighted blankets lies in their simplicity. They typically weigh between two and 13 kilograms (experts often suggest choosing one that’s about 10% of your body weight) and utilize what therapists refer to as “deep pressure stimulation.” This gentle, uniform pressure mimics the comforting sensation of being held or hugged.
What the science says
The scientific evidence surrounding these blankets is more complicated than the marketing suggests. While some studies show encouraging results, they come with essential qualifications.
For instance, a study involving 120 psychiatric outpatients indicated that weighted blankets improved insomnia symptoms over a month in participants with major depression, bipolar disorder, anxiety, and ADHD. Researchers concluded that they could be “a safe and effective intervention for insomnia in patients with certain mental health disorders.”
Other smaller studies corroborate these findings. One indicated that 63% of adults experienced reduced anxiety after just five minutes under a weighted blanket, while another study involving psychiatric inpatients found that 60% had less anxiety during their stay.
However, these studies predominantly focused on individuals with diagnosed mental health issues, rather than the broader population that companies are now targeting.
This is where the gap between science and marketing appears: reviews consistently indicate that benefits for healthy individuals are much harder to substantiate. While weighted blankets may aid those with clinical anxiety or sleep disorders, there’s insufficient evidence suggesting they benefit casual users without pre-existing mental health conditions.
Additionally, approximately half of the research on these blankets fails to meet quality standards for reliable scientific evidence, which raises concerns given the assertive health claims made by product manufacturers and positive reviews in lifestyle publications.
Who might benefit?
This doesn’t imply that weighted blankets have no value for healthy individuals. For shift workers who sleep during the day, when their brains are naturally more alert, these blankets might prove useful against the health impacts of irregular schedules. Healthcare professionals, firefighters, and pilots who rely on strategic naps could also benefit from quicker sleep onset.
And let’s not overlook the placebo effect. If a weighted blanket makes you feel calmer and helps you sleep better—regardless of whether it works as manufacturers suggest—that’s still a positive result, as long as you’re aware of what you’re purchasing.
Of course, weighted blankets do carry some risks. They shouldn’t be used by anyone unable to easily move beneath the weight, including young children. Those with diabetes, asthma, sleep apnea, COPD, circulation issues, high blood pressure, or claustrophobia should consult a healthcare professional before using one.
No serious hazards have been reported, but it’s wise to check with a doctor if you have any underlying health conditions.
As a low-risk option that might complement good sleep practices and consistent sleep cycles, weighted blankets aren’t inherently problematic. The real issue lies with overinflated claims about their effectiveness.
If you’re thinking of getting one, it’s best to set realistic expectations. You aren’t purchasing a miracle solution for modern anxiety, but rather a potentially comforting sleep aid that could help you feel more at ease come bedtime. For many grappling with sleep issues, that gentle pressure and sense of security might be worth the investment, even if the science isn’t as robust as the marketing implies.
The ultimate question isn’t really whether weighted blankets work, but rather if they work for you and whether the cost is worth it for what may just be an expensive hug.
