Late Night Smart Phone Use Could Affect Sleep

Posted: Updated:

EAST LANSING, Mich. (WLNS) - New research from Michigan State University shows that if you're using your phone to keep tabs on your job at night, your sleep schedule could be suffering.

Two studies surveyed some American workers and found those who used their smart phones for their job after 9p.m. were more tired and less engaged at work the next day. The researchers say monitoring your job using your phone at night keeps you from disengaging from work and makes it harder to fall asleep.

The studies say smart phones showed more negative effects than watching television or working on a laptop or tablet at night because the blue light that cell phones give off disrupts the chemical your body needs to sleep.

The National Sleep Foundation found only 40 percent of Americans get enough sleep on most nights and a commonly cited reason is smartphone use.
