The Weisman has an exhibit running about SAD, or Seasonal Affective Disorder. Having lived in Alaska, I can say that darkness really does change people for the worse.
However, summer’s version of SAD receives little attention. For example, Carly came back from a run with a runner’s high after running on a beautiful summer morning with blue skies and plenty of sun. Surely the weather affected her mood as well? Shouldn’t something be done to prevent overly beautiful days from creating irrationally exuberant behavior?
Someone needs to study this, pronto.
