April 2, 2018 -- Toddlers have long used “blankies” to help them feel secure, dry tears, and fall asleep quickly.

Now, some adults with insomnia, depression, and anxiety are rediscovering that feeling of security -- for a price -- in the form of weighted blankets.

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.

She has no idea how the blanket works but is happy it does.

What Is a Weighted Blanket?

Weighted blankets are usually filled with plastic pellets to add weight, ranging from about 4 to 25 pounds. You pick the heaviness of the blanket based on your own weight. Prices range from about $120 to $249 or more.

People compare a weighted blanket’s “hug” to the feeling of the X-ray ''apron'' the dentist puts on you, says David Fuchs, CEO of BlanQuil, one of the makers of weighted blankets.

Other companies include Gravity Blanket, Mosaic Weighted Blankets, and SensaCalm. Fuchs launched his product in December 2017, after he searched for something to help his adult daughter improve her sleep.
