ONCE a niche therapeutic tool, weighted blankets have surged into the mainstream, touted as remedies for anxiety and sleeplessness.
Celebrities and influencers swear by their calming effects, and wellness brands now market them to the “casually anxious” – anyone overwhelmed by modern life.
But do they live up to the hype?
Originally used by occupational therapists in the 1970s to support children with autism and adults with sensory disorders, weighted blankets became commercially available in the 1990s. Their popularity exploded after Time magazine named them one of 2018’s top 50 inventions.
Typically weighing between 2 and 13 kilograms, these blankets rely on “deep pressure stimulation” – a gentle, even pressure that mimics the sensation of being hugged.
The idea is simple and appealing, but the science behind it is more complex.
Research shows promising results, particularly for people with diagnosed mental health conditions.
A study of 120 psychiatric outpatients found weighted blankets improved insomnia symptoms in individuals with depression, anxiety, bipolar disorder or ADHD.
Other studies report reduced anxiety in psychiatric inpatients and calmer feelings after just five minutes under a blanket. However, these studies focus on clinical populations – not the healthy consumers now being targeted.
Reviews consistently show limited evidence that weighted blankets benefit people without diagnosed conditions.
Moreover, about half the existing research lacks the rigour needed to support strong health claims.
Still, some healthy individuals may find them useful. Shift workers, healthcare professionals, and others with irregular sleep schedules might benefit from faster sleep onset.
And the placebo effect shouldn’t be dismissed – if it helps you feel calmer and sleep better, that’s a win.
Weighted blankets aren’t risk-free. They’re unsuitable for young children or anyone unable to move easily beneath their weight.
People with diabetes, asthma, sleep apnoea, circulation issues, high blood pressure, or claustrophobia should consult a doctor before use. While no serious harms have been reported, caution is advised.
Ultimately, weighted blankets may offer comfort – but they’re not a miracle cure. If you’re considering one, be realistic.
You’re investing in a potentially soothing sleep aid, not a guaranteed solution.
