What is the safety and effectiveness of weighted blankets for symptom management in patients with mental disorders?
Weighted Sleep Blanket Pro, a meta-analysis (Complement Ther Med 2024, PMID 39447684) — the pooled estimate of three studies for insomnia was non-significant (MD = -1.92, 95% CI = -3.92-0.09, p = 0.06), but a sensitivity analysis of two homogeneous studies revealed reduced insomnia severity (MD = -2.78, 95% CI = -4.44 to -1.12, p = 0.001).

Weighted blankets appear to be a safe and potentially effective complementary treatment for anxiety, insomnia, depression, and fatigue in people with mental disorders, but more robust research is needed.
The question
What is the safety and effectiveness of weighted blankets for symptom management in patients with mental disorders?
What they tested
The study aimed to systematically evaluate and synthesize existing data on the safety and effectiveness of weighted blankets for symptom management among patients with mental disorders.
How they did it
A comprehensive search was conducted across bibliographic databases, grey literature, and clinical trial registries for randomized controlled trials (RCTs) comparing weighted blankets to control conditions in patients with mental disorders. Two reviewers independently extracted data and assessed methodological quality using the RoB 2 tool. Meta-analysis was performed using Review Manager 5.3, with subgroup and sensitivity analyses where appropriate.
What they found
Eight studies involving 426 patients were included. Half of the studies had a high risk of bias due to unblinded participants for self-reported measures. No serious adverse events were reported. Meta-analysis of five studies showed a small decrease in anxiety (SMD = 0.40). The pooled estimate of three studies for insomnia was non-significant (MD = -1.92, 95% CI = -3.92-0.09, p = 0.06), but a sensitivity analysis of two homogeneous studies revealed reduced insomnia severity (MD = -2.78, 95% CI = -4.44 to -1.12, p = 0.001). Primary studies also reported positive effects on fatigue and depression, though summary estimates were not computed due to heterogeneity.
| Anxiety (SMD) | 0.4 | |
|---|---|---|
| Insomnia (MD) | -1.92 | |
| Insomnia (MD, sensitivity analysis) | -2.78 |
Standardized Mean Difference (SMD) for anxiety and Mean Difference (MD) for insomnia, showing a small decrease in anxiety and a reduction in insomnia severity in a sensitivity analysis.
What it means
Weighted blankets may be a safe and effective add-on treatment for managing anxiety, insomnia, depression, and fatigue in psychiatric patients. However, these findings require further confirmation due to the limited number of studies, small sample sizes, and significant heterogeneity.
Limitations
The review included a limited number of studies with small sample sizes and significant heterogeneity. Half of the included studies had a high risk of bias, mainly due to the inability to blind participants for self-reported outcomes.

Weighted Sleep Blanket Pro
Across randomized controlled trials and meta-analyses, weighted blankets have most consistently shown modest reductions in anxiety and in self-reported insomnia severity, particularly among adults with psychiatric conditions—one well-designed trial in that population reported a large effect on insomnia severity…
