2When her husband gave her a weighted blanket to help her sleep, Rhonda James did not think it would work.
3In other words, she was skeptical. But five minutes after covering herself with the blanket, she was asleep.
4"It felt like a really big hug," said James.
5She is a banker who lives in Charleston, South Carolina.
6As temperatures drop, a weighted blanket can be a popular choice to help you keep warm.
7But some people say the extra pressure of the cover also helps to ease their worries and fall asleep faster.
8However, research on the effectiveness of weighted blankets is limited.
9The Associated Press recently reported on what is known about weighted blankets.
10Weighted blankets are filled with small glass balls, cotton or another filling.
11This makes them heavier than usual blankets.
12Scientists may not know exactly how the blankets comfort, but they have a few ideas.
13The heavy, even feeling from a weighted blanket may calm the brain's fight-or-flight response, said Dr. Neal Walia.
14He is a sleep medicine expert at University of California, Los Angeles Health.
15He said, "The evenly distributed weight on you tells your body..." you are in a "...calm environment.'"
16The extra pressure also may cause the brain to release the hormone oxytocin.
17Sometimes called the "love hormone," the body creates oxytocin during loving moments, such as hugging. Oxytocin can also lower anxiety, Walia said.
18For most healthy adults, experts say to choose a blanket that is about 10 percent of your body weight.
19However, the blankets are not good for everyone.
20For example, some people may find them too hot to use, especially during warmer weather.
21People with breathing problems or disorders such as sleep apnea should check with a doctor before using a weighted blanket.
22Experts say to not use weighted blankets for children under three years old.
23The weight can limit their movement and breathing.
24Some people may not be able to buy them. They can be costly.
25A quality weighted blankets can cost between $50 to over $300.
26This depends on the size, weight and material.
27Some people use them for other reasons than sleep.
28Rhonda James gets under her blanket to relax as she watches television or drinks a glass of wine.
29Lucy Taylor, a writer from Wales, also uses a weighted blanket.
30Her anxiety increases during the winter.
31So, she uses her blanket during cold months to fall asleep.
32She says when her body is relaxed, her mind relaxes too.
33There is little scientific research on whether weighted blankets help with sleep, anxiety, or other health issues.
34The studies that exist involve small groups of people.
35And most of the study subjects are people with conditions including sleep problems, long-term pain, and mental and developmental disorders.
36A 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.
37Another study considered 67 children with the developmental and brain disorder autism.
38That research found that weighted blankets did not affect the children's sleep at all.
39However, it also found that the study subjects liked the weighted blankets more than non-weighted blankets.
40A third study on 94 adults with chronic pain found that a heavier weighted blanket did not affect sleep.
41But it was better at reducing pain than a lighter blanket.
42So, there is not much scientific evidence to support health improvement claims about weighted blankets.
43However, in most cases they also cannot hurt, sleep experts say.
44Dr. Daniel Barone is a sleep medicine expert at Weill Cornell Medicine in New York City.
45He suggests the use of weighted blankets to his patients after they try other traditional treatments and medicines.
46"If it doesn't hurt and it may help, it's worth a shot," he said.
47And that's the Health & Lifestyle report.
