Winter can be a difficult time of year. For some students, it could be seasonal affective disorder (SAD).

What is SAD?
SAD is depressive symptoms that come and go during a particular time of year. SAD is now considered a subtype of either depression or bipolar illness (1).
Two seasonal patterns of SAD are fall-onset SAD and the summer-onset SAD. The fall-onset type, also known as “winter depression,” is more common; with depressive symptoms starting in the fall and improving by spring or summer. A spring-onset, fall-offset pattern is quite rare (2).

How common is SAD?
•SAD can occur in up to roughly 10% of the population across 20 retrospective studies (5) and a milder form among 10% to 20 % of the population (7).
• It is more common at higher northern latitudes (further away from the equator) (6), possibly because of less sunlight.
• People who relocate to higher latitudes from lower latitudes can be more vulnerable (5).

What are the symptoms of SAD?
Fall-onset tends to have what I call, “hypoactive type” symptoms depression (1,3), with symptoms of:
• Depressed mood AND
• Increased sleep, increased appetite with carbohydrate craving
• Increased weight
• Irritability
• Interpersonal difficulties (including sensitivity to rejection)
• Heavy, leaden feelings in arms or legs

Spring-onset SAD can have “hyperactive type” symptoms of depression such as insomnia, poor appetite, and weight loss.

What can students do to prevent or lessen SAD symptoms?
• Get active by exercising (check with your doctor first)
• Eat a healthy balanced diet of protein/veggies/fruit/whole grains, Omega 3’s
• Don’t isolate from family, friends, or colleagues and get involved on campus
• Take advantage of sunny days (open blinds, study near windows, time outside if possible, etc)
• Counseling
• Talk to your doctor about light therapy, medication options.

What are some of OSU’s campus resources for SAD?
• Student Wellness center (Wellness coaching, nutrition)
• Exercise at the RPAC
•  Counseling and Consultation Service
• Wilce Student health center

Are there any other helpful resources?
