(Corvallis, OR) -- Being lonely is a bigger cause of insomnia than screentime. Oregon State University led research that studied one-thousand undergraduate students. The researchers found that 35 percent of students having trouble sleeping had high levels of loneliness. Daily screentime of between eight and ten hours was also a cause of insomnia, but loneliness was a bigger factor. Researchers say universities should work to reduce loneliness among students and recommend they limit screentime to less than eight to ten hours a day.
