The researchers analyzed data on 653 adults enrolled in the internet-based Health eHeart Study. “But in thinking about the fact that this is an hour and a half of uninterrupted time, that is a pretty significant part of our day.“This is a lot better than the usual surveys where people estimate how much they use their phone,” said Michael Gradisar of Flinders University School of Psychology in Adelaide, Australia.“This is the first study to directly measure actual screen time in natural environments and compare it to sleep quality,” said senior author Dr.”.“At first glance, that we on average spend about an hour and a half of our time interacting with our phone every day may not seem surprising,” Marcus told Reuters Health by email.7 minutes, equivalent to one hour and 29 minutes per day, according to the report in the journal PLoS ONE. “I was surprised that people are using their phones for one to two hours per day. Screen time varied by age and race but was similar for people with the same socioeconomic background.“Avoiding smart phone screens is almost certainly low risk,” he said.
“Therefore, if an individual is having difficulty falling asleep or maintaining an adequate quality of sleep, I think our observations support a good trial of screen time avoidance to determine if it helps that person obtain a good night’s sleep.But this study does not prove causality, as people with difficulty sleeping may spend more time on their phone as a result of their inability to sleep, he said. “We did not rely on participant self-report, but rather utilized a mobile app that ran in the background and could capture exact screen time duration. Gregory M. As in previous studies of self-reported screen time, as screen time increased, pvc single hung window Factory sleep quality decreased, including taking more time to fall asleep and getting less time asleep overall.Using smartphones to measure how much time people spend looking at those phones confirms that more screentime is tied to poorer sleep, researchers say. I thought it would be more than that.”Younger people tended to have longer screen time.Some participants self-reported their bedtime and sleeping period as well as personal demographics and medical information.
This app collected data continuously over a 30-day window. The light produced by smart phones might suppress production of melatonin, which is related to sleep, Marcus said.Participants’ smartphones were provided with a mobile application that recorded screen time, or the number of minutes in each hour that the phone screen was on. Total screen time averaged 38.”Television, which also involves a screen but is not interactive, may not be linked to sleep in the same way, Gradisar told Reuters Health by email.“However, it is also possible that engrossing activities that result in stimulation, such as following the latest post on Facebook or a bothersome tweet, might be counter to productive sleep preparation,” he said.Younger people tended to have longer screen time.“More screen time right around participant-reported bedtime was particularly associated with longer sleep latency (or a longer time to fall asleep) and reduced sleep quality,” Marcus said. “We know that poor sleep leads to many health problems, and we are only now beginning to fully recognize the negative impact on the cardiovascular system,” Marcus said.
