Mark Frauenfelder, writing at Boing Boing:
"A recent study of sleep loss and depression found that one night of total sleep deprivation generally worsens mood and emotional regulation in healthy individuals, but induces a temporary lift in spirits for some individuals with depression.
. . .
The findings were remarkable: lack of sleep escalated negative mood among the healthy subjects, but eased depressive symptoms in 43% of the patients with depression."
