Sleep deprived?

Your smartphone may lead to poor sleep, study says

CNN – Using your smartphone especially near bedtime could affect how much and how long you sleep.

University of California at San Francisco researchers studied data on more than 650 adults enrolled in an internet-based health study. Participants’ smartphones were provided with an app that recorded the number of minutes that the phone screen was on every hour. Everyone was monitored for a month and analysts used a sleep quality index to assess sleep duration and quality.

The team found as smartphone use increased, particularly around bedtime,sleep duration and quality decreased. Investigators say further research is needed on a wider scale as their participants were predominantly white females and only one type of smart phone was used during this study.
