A review by Flinders University researchers in Australia explored weighted blankets’ effects on sleep, anxiety, and depression. The study, led by Dr. Suzanne Dawson, a mental health expert, analyzed 18 studies. They found that weighted blankets significantly improved sleep, reduced sleep medication reliance, and enhanced mood.
Dr. Dawson emphasized, “Weighted blankets offer a practical, non-pharmaceutical way to enhance sleep quality.” She noted users experienced better sleep, reduced medication use, and mood improvements. Some users also reported relief from pain.
Limited Benefits for Children and Teenagers
While adults experienced significant benefits, the review found mixed results for children and teenagers. These findings were published in the American Journal of Occupational Therapy.
The research team highlighted the need for clear guidelines on blanket weight and safety measures. They stressed the importance of ensuring users can easily remove the blanket themselves. Dr. Dawson stated, “This review aimed to guide practice changes, and we’re pleased to see its impact on South Australia’s public mental health services.”
Weighted blankets come in different types, often filled with beads or chains, and vary in weight. However, no standardized guidelines exist for the type, weight, frequency, or duration of use.
Research Limitations and Expert Perspectives
Dr. Zhou, who was not involved in the study, noted certain limitations in the existing literature. He explained that most included studies were conducted by the same research groups or focused on specific subpopulations. Due to these constraints, only a small number of studies met the review’s inclusion criteria. He called for further research to support broader conclusions.
Rising Sleep Issues Across Populations
Sleep disturbances are becoming a growing concern. One in ten adults in Europe experiences chronic insomnia, with women being disproportionately affected. In countries like Portugal, France, and Belgium, one in five adults reports sleep problems.
Dr. Dawson emphasized the health risks of poor sleep. “Sleep is a fundamental human need. Insufficient sleep can worsen chronic conditions like heart disease, stroke, and mental health disorders,” she explained.
Previous research has linked sleep deprivation to cognitive decline and emotional instability. Dr. Dawson concluded, “While more rigorous studies are necessary to define the optimal use of weighted blankets, their potential benefits justify further exploration in practice.”
