Seasonal Affective Disorder
Understanding Seasonal Affective Disorder in Alaska
Seasonal Affective Disorder (SAD) is a form of depression tied to the changing seasons. It typically appears in late fall and winter and lifts in spring. The DSM-5 classifies it as a major depressive disorder "with seasonal pattern," rather than its own separate diagnosis. Reduced sunlight disrupts our circadian rhythms, lowers serotonin activity, and increases melatonin production, and is thought to be the main driver of SAD.
Alaskans understand the difficulties of long, harsh winters. For some Alaskans, the winters pass in a flurry of outdoor adventure. Other Alaskans feel solar-powered and therefore depleted during the long winters. Alaska's extreme seasonal light variation makes SAD an especially common problem.
Common symptoms of SAD include:
Low energy and oversleeping
Carbohydrate cravings and weight gain
Trouble concentrating
Withdrawal from friends and family
In severe cases, suicidal thoughts
The clearest sign of SAD is a pattern of feeling noticeably more depressed, tired, or unmotivated each fall and winter, then improving each spring and summer, for at least two years in a row. A mental health professional can help confirm this pattern and rule out other causes.
Treatment Options for Seasonal Affective Disorder
-
Psychotherapy can help people at any severity level, but is especially valuable for those with recurring or more intense symptoms, or when light therapy and medication are insufficient. Cognitive Behavioral Therapy has strong research support for Seasonal Affective Disorder; benefits can last into future winters, as this approach teaches coping strategies.

-
Regular physical activity, consistent sleep routines, healthy eating habits, and social connection can meaningfully uplift mood and improve overall well-being and self-regulation.
-
For people with Seasonal Affective Disorder, medication alone is rarely sufficient, but it provides a real boost, and in combination with light therapy, lifestyle changes, and psychotherapy it can produce meaningful improvement.
SSRIs target serotonin re-uptake in the brain, and are often the first-line psychiatric treatment for Seasonal Affective Disorder. Other medications, such as SNRIs and tricyclic antidepressants, also target norepinephrine signaling to stabilize and lift mood.

Outcomes are best for patients with a coordinated care team that includes a mental health provider and a medication provider. At Alaska Telepsychology, we lean into this by providing psychological testing, psychiatry, and psychotherapy in-house and by coordinating with professionals outside our clinic.
Uniquely Alaskan Challenges
Seasonal affective disorder (SAD) hits with particular force in Alaska because of our state's extreme latitude and light deprivation. In places like Utqiagvik or Fairbanks, winter can bring weeks or even months of near-total darkness or only a few hours of dim daylight, far beyond the shortened days that trigger SAD in most of the continental U.S., meaning symptoms can be more severe, start earlier in the fall, and last longer into spring. This intense light scarcity disrupts circadian rhythms and melatonin regulation more profoundly, often producing pronounced fatigue, sleep disturbances, low mood, and difficulty concentrating that can feel less like a seasonal dip and more like a prolonged shutdown.
Compounding this, many Alaskans live in remote or isolated communities with limited access to mental health providers, light therapy equipment, or psychiatric care, so treatment is often delayed until a provider is reached by phone, telehealth, or an expensive long-distance trip. The logistical and financial barriers of traveling to Anchorage or other resource hubs can be prohibitive. Our state's brutal cold and difficult travel conditions also discourage the outdoor activity and social contact that can buffer depressive symptoms elsewhere, deepening isolation during the very months when connection matters most. Finally, the flip side of the cycle, near-constant summer daylight, can also disrupt sleep and mood regulation, meaning some Alaskans effectively contend with two disruptive light extremes each year rather than one seasonal shift, making steady mental health management more complex year-round.
