But can a little extra weight really help you sleep better?
Leslie Kosco, 56, an oncology nurse in Indianapolis, thinks so. For the past 3 months, she has snuggled under her light gray, 20-pound weighted blanket. She bought it after reading that it could improve sleep and lower anxiety.
"It gives me the feeling that someone is hugging me, and making me feel calmer," she says. "I think my sleep is better." The anxiety? "Well, you know," she laughs. She works with cancer patients, and she and her partner have an active 9-year-old.
