Can weighted blankets improve sleep? There is little scientific research on whether weighted blankets help with sleep, anxiety, or other health issues. The studies that exist involve small groups of people. And most of the study subjects are people with conditions including sleep problems, long-term pain, and mental and developmental disorders. 

关于加重毯子是否有助于睡眠、焦虑或其他健康问题的科学研究很少。现有的研究涉及一小群人。大多数研究对象都是患有睡眠问题、长期疼痛以及精神和发育障碍等疾病的人。 

A study on 120 people with insomnia, an inability to get enough sleep, found that the weighted blankets helped them sleep better compared to a light blanket. 

一项针对 120 名失眠症患者（无法获得足够睡眠）的研究发现，与轻薄的毯子相比，加重的毯子可以帮助他们睡得更好。 

Another study considered 67 children with the developmental and brain disorder autism. That research found that weighted blankets did not affect the children’s sleep at all. However, it also found that the study subjects liked the weighted blankets more than non-weighted blankets.

第三项针对 94 名患有慢性疼痛的成年人的研究发现，较重的毯子不会影响睡眠。但它比更轻的毯子更能减轻疼痛。 

So, there is not much scientific evidence to support health improvement claims about weighted blankets. However, in most cases they also cannot hurt, sleep experts say. 

因此，没有太多科学证据支持加重毯子改善健康的说法。然而，睡眠专家表示，在大多数情况下，它们也不会造成伤害。 

Dr. Daniel Barone is a sleep medicine expert at Weill Cornell Medicine in New York City. He suggests the use of weighted blankets to his patients after they try other traditional treatments and medicines. 

丹尼尔·巴龙 (Daniel Barone) 博士是纽约市威尔康奈尔医学院的睡眠医学专家。他建议患者在尝试其他传统疗法和药物后使用加重毯子。 

“If it doesn’t hurt and it may help, it’s worth a shot,” he said. 

“如果它没有伤害并且可能有帮助，那就值得一试，”他说。
