Smartphone Use at Night

Smartphone Use at Night

by Berkeley Wellness  

Want to be more productive in the office? Resist the urge to use your smartphone for work late at night. So suggests a study in Organizational Behavior and Human Decision Processes that surveyed the nighttime smartphone use of 82 higher-level managers and 161 employees in various occupations such as law and media.

Using a smartphone for business purposes after 9 p.m. disrupted sleep, leaving employees feeling more depleted and less engaged at work the next day. Not only do smartphones (and other electronic devices) make it hard to detach from work, the blue light emitted from them inhibits production of melatonin, a hormone that helps promote sleep. If you can’t put work off till the next day, at least try to finish up what you need to do earlier in the evening.
