The SunSentinel reports on research by Jamie Tartar that links sleep deprivation and emotional sensitivity.

New research from Nova Southeastern University shows that if you don’t get enough zzzzz’s, even the sight of a pencil or coffee cup can make you emotional.

The sleep deprived are “more sensitive,” said Jamie Tartar, an associate professor at the College of Arts and Sciences. “You’re not in a blunted and general zombie-like state.”
