This confirms what I’ve thought for a while, and it’s also why my daughter’s phone gets to sleep downstairs at night. I’ve found that I am definitely less engaged with the emails, and much less likely to completely follow through the next day- to my own detriment!
“A new study from Michigan State University’s business school finds that using your phone to get in a few more minutes of work at night has the totally counterproductive effect of making you less engaged when you get to the office the next day. In two different studies, one with 82 upper-level managers and one with 161 employees from fields like nursing and manufacturing, the researchers found work-related smartphone usage ruined people’s energy levels the next day.”
