Late Night Smartphone Use Affects Productivity
Research suggests that you should put away your smartphone at the end of the work day in order to be more productive the following day. Michigan State University business scholar, Russell Johnson and colleagues discovered that workers that tried to continue working on their smartphone past 9:00 p.m. were more worn out and less engaged during the following work day. “Smartphones are almost perfectly designed to disrupt sleep,” said Johnson, MSU assistant professor of management who acknowledges keeping his smartphone at his bedside at night. “Because they keep us mentally engaged late into the evening, they make it hard to detach from work so we can relax and fall asleep.”According to research, at least 50{c754d8f4a6af077a182a96e5a5e47e38ce50ff83c235579d09299c097124e52d} of U.S. adults own a smartphone.

Michigan State University business scholar, Russell Johnson and colleagues discovered that workers that tried to continue working on their smartphone past 9:00 p.m. were more worn out and less engaged during the following work day.
“Smartphones are almost perfectly designed to disrupt sleep,” said Johnson, MSU assistant professor of management who acknowledges keeping his smartphone at his bedside at night. “Because they keep us mentally engaged late into the evening, they make it hard to detach from work so we can relax and fall asleep.”
According to research, at least 50{c754d8f4a6af077a182a96e5a5e47e38ce50ff83c235579d09299c097124e52d} of U.S. adults own a smartphone. Many of them consider their phones to be critical workforce productivity tools; however the National Sleep Foundation indicates that only 40{c754d8f4a6af077a182a96e5a5e47e38ce50ff83c235579d09299c097124e52d} of Americans get enough sleep on most nights. Likewise, much of the self-reported data suggests that the lack of sleep can be attributed to smartphone usage for work.
To study this phenomenon, researchers asked 82 upper-level managers to complete multiple surveys daily for two weeks. They also surveyed 161 employees daily in a variety of occupations, such as nursing, manufacturing and dentistry etc.
All workers from all occupations indicated in their surveys that smartphone use for business purposes affected their sleep and drained their energy the following work day. The study also noted that smartphones more negatively impacted workers than watching television or using laptops and tablet computers.
“In addition to keeping people mentally engaged at night, smartphones emit “blue light” that seems to be the most disruptive of all colors of light. Blue light is known to hinder melatonin, a chemical in the body that promotes sleep.”
It seems that smartphone use late at night impacts the amount and quality of sleep we get, which affects our attention and abilities the following day. That being said, this small study may be reason enough to turn that phone off after 9:00 p.m. to see how it might benefit us physiologically and psychologically.
