Sleep disorder doctors say there’s little evidence consumer gadgets actually improve sleep, reports the New York Post.
“The technology can help describe the problem,” such as waking repeatedly or too early, said Dr. Douglas Kirsch, president of the American Academy of Sleep Medicine. “It does not tell you what the cause is” or how to fix it.
Experts say such products have some value: They make people focus on and try to improve their sleep.
According to the U.S. Centers for Disease Control and Prevention, about one-third of adults and two-thirds of high school students report regularly getting less than the recommended amount of nightly sleep — seven hours for adults and eight to 10 hours for teens.
