DEAR DOCTORS: My niece got me a weighted blanket for my birthday, which she says helps you sleep. I admit I was sceptical, but I used it for a month, and she may be right. Instead of waking up a few times at night, I sleep right through. Is it the power of suggestion, or is there a reason this is working?
DEAR READER: Weighted blankets have become increasingly popular in recent years. They were originally developed as a therapeutic tool to help people with conditions such as autism, in which anxiety can be a persistent symptom.
