Smartphones can make you lose sleep
In an April 2015 survey for Bank of America, 71% of Americans said they sleep with or next to their smartphones. That convenience could be shutting down their ability to get some shuteye.
Medical experts at Pennsylvania State University say that everyone should stop using electronic devices such as smartphones at least an hour before bedtime so the glow emitted by the devices doesn't disturb the ability to produce melatonin, a natural hormone that's vital to regulating our sleep cycles.
That's especially pertinent advice for the estimated 30% of American adults who suffer symptoms of insomnia.
