Smartphones are indispensable part of everyday life, but questions remain about the effects of frequent use of sleep. Poor sleep is associated with health conditions such as obesity, diabetes and depression.
Researchers from the University of California San Francisco, USA found a link between smartphone screen exposures and sleep quality. People who spent more time staring at their smartphones screen tended to have unhealthy sleep patterns and sleep was of poorer quality.
The team collected data from 653 adults that were part of the Health eHeart study. Each Participant was required to install an app that would track how often their phone’s screen was on, which will allowed the researchers to determine an individual’s screen time.
It is found from the study that Screen time varied by age and race but was similar for people with the same socioeconomic background. Younger people tended to have longer screen time.
As in previous studies of self-reported screen time, as screen time increased, sleep quality decreased, including taking more time to fall asleep and getting less time asleep overall.
