Summer is a time of outdoor fun for many people, especially those who have slogged through winter’s bitter cold. Not so for individuals who suffer from summer depression.

Heat, humidity and pollen likely cause summer sadness, while reduced daylight causes winter seasonal affective disorder (SAD).

Compared with winter SAD, summer depression has not received as much attention, either in research or more general awareness.
