Using a smartphone at night hurts work performance the next day

New research indicates that greater connectivity comes at a cost: Using a smartphone to cram more work into an evening results in less work being done the next day.

Smartphones are bad for sleep and sleep is very important to employee effectiveness, says a Harvard Business Review blog post by researchers Christopher M. Barnes, Klodiana Lanaj and Russell Johnson.

The researchers suggest one solution is to agree that evenings and normal sleeping hours are important times for people to be predictably “off.” This will allow employees to properly disengage from work. ◊
