Early in his career, Teodor Postolache, a psychiatry professor at the
University of Maryland, was struck by a peculiar trend that comes up again
and again in suicide research. Across decades and in various countries,
suicide is much more common in the spring and early summer than other times
Now, Postolache and other researchers believe they have found a curious link
between the season and self-harm: pollen-induced allergies.
