Nighttime smartphone use zaps workers’ energy

russell-johnson_lgInteresting study from Michigan State University researchers on use of smartphones at night and resulting productivity the next day. The head researcher claims “smartphones are almost perfectly designed to disrupt sleep.” I think Volkswagon recognized this years ago in a post I had back in 2011 entitled “Volkswagen turns off Blackberry email after work hours.”

Using a smartphone to cram in more work at night results in less work the next day, indicates new research co-authored by a Michigan State University business scholar.

In a pair of studies surveying a broad spectrum of U.S. workers, Russell Johnson and colleagues found that people who monitored their smart phones for business purposes after 9 p.m. were more tired and were less engaged the following day on the job.

smartphone“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.”

More than half of U.S. adults own a smartphone. Many consider the devices to be among the most important tools ever invented when it comes to increasing productivity of knowledge-based work, Johnson said.

Yet at the same time, the National Sleep Foundation says only 40 percent of Americans get enough sleep on most nights and a commonly cited reason is smartphone usage for work.
