What’s the difference between Seasonal Affective Disorder (SAD) and “Winter Blues”?

The first hard frost hits, the sun slips below the horizon by 4:30 p.m., and suddenly the couch feels like the only safe place in the world. You tell yourself it’s just the “winter blues.” You’ll snap out of it when the holidays pass. But weeks drag on, and the heaviness lingers—sleeping 10 hours yet waking exhausted, skipping the gym, snapping at your kids or spouse, staring at your phone without really seeing it. If this sounds familiar, you don’t have to walk through this season alone.

Brandi Salvatore, LCSW, is a Case Manager and clinician at our Steven A Cohen Military Family Clinic. She’s also the creator of the clinic’s Winter Mental Health Lunch & Learn series. (Look for details about the 2026-2027 series soon!) Brandi connects clients with community resources and has run group therapy at the clinic, including: Effective Communication for Couples, Paws & PTSD, Anger Management for Adults, and Sleep Well/Dream Well (for insomnia).

Rani Malone is the Behavioral Health Care Manager embedded inside our primary-care clinic. Through her practice, Rani is able to work with clients and offer skill-building around symptom management, as well as connection to the community to improve mental health, in addition to therapy. Similar to what she does with clients in her role every day, Rani has helped us compile a list of tips to support your mental health this winter.

Seasonal Affective Disorder (SAD) vs. Winter Blues

Across the board, many Alaskans dismiss their symptoms as “normal winter fatigue” until the pain becomes unbearable and they are struggling to maintain regular household tasks or start to withdraw from activities they once loved.

Winter blues are real, but they’re mild and self-limiting. You might feel a little sluggish, crave carbs, and count the days until spring. Daily life rolls on with minimal friction.

Seasonal Affective Disorder is Major Depressive Disorder with Seasonal Pattern (DSM-5). Symptoms must:

  • Begin and remit in a seasonal pattern
  • Most typically, symptoms begin in fall/winter and ease in spring/summer
  • Recur for at least two consecutive years
  • Significantly impair work or daily tasks, relationships, or self-care

Women are diagnosed four times more often than men, though researchers suspect under-reporting in males due to stigma.

“People come in saying, ‘I’m just tired all the time.’ When we dig deeper, we learn they sleeping 12 hours, calling in sick, no longer engaging in the usual activities, isolating, and we realize it’s crossed the line into SAD,” Brandi explains. “If these symptoms are ongoing for more than two weeks, it’s time to reach out.”

The Science: Why Daylight Dictates Mood

Three biological dominoes fall when the sun retreats:

  1. Serotonin plummets. This neurotransmitter that stabilizes mood. Less UVB light → fewer serotonin molecules in the suprachiasmatic nucleus (the brain’s master clock).
  2. Vitamin D tanks. Skin synthesis drops 80–90% in winter above 37° latitude (think Seattle northward). Low D is linked to depressive symptoms independent of sunlight (click here to learn more).
  3. Melatonin overproduces. Shorter days trick the pineal gland into releasing melatonin earlier and longer → daytime drowsiness, disrupted sleep architecture.

The result? A perfect neurological storm for depression.

Recognizing SAD: Symptoms Checklist

Check any that have lasted most of the day, nearly every day, for two weeks:

  • Persistent sadness or emptiness
  • Loss of interest in your usual hobbies (anhedonia)
  • Fatigue, despite extra sleep
  • Appetite/weight changes (usually increase + carbs but can vary between individuals)
  • Unexplained aches, headaches, GI issues (especially in children)
  • Trouble concentrating or brain fog
  • Social withdrawal
  • Hopelessness
  • Suicidal thoughts or planning

Red-Flag Behaviors (Brandi’s “Call 988” list):

  • Talking about death or being a burden
  • Sudden alcohol or cannabis spikes
  • Giving away prized possessions
  • Reckless driving or spending (carelessness)
  • Saying goodbyes to loved ones and friends

If you check 5+ boxes or spot red flags, text or call 988 immediately. Crisis counselors are available 24/7.

Rani’s favorite tip to overcoming SAD is to check in with neighbors and friends: it’s mutually beneficial for all involved! “Asking people how they’re doing and trying to just connect and plan things – social connection is going to be a huge thing that’s going to help you get through the season.”

Who’s at Highest Risk?

Risk FactorWhy It Matters
WomenHormonal interplay with serotonin pathways
Young adults (18–30)First episodes often emerge here
Northern latitudesAlaska: 1 in 12; Florida: 1 in 100
Family history55% heritability for mood disorders
Prior depression/bipolarSeasonal pattern can layer on top

SAD in the Military Community

Deployment cycles already scramble circadian rhythms: 12-hour night shifts in theater, red-light-only tents, months without natural dawn. Add an Alaskan winter homecoming and the risk compounds. Brandi, Cohen Clinic Case Manager, sees it weekly.

Consequences ripple:

  • Safety: Slower reaction times in -20°F live-fire drills.
  • Retention: Untreated SAD can correlate with early separation.
  • Families: Spouses report “my spouse came home but isn’t really here.”

Getting Diagnosed: Where to Start

  1. Primary Care: Talk to your primary care provider about the symptoms you may be experiencing. (AKBH also offers primary care. Ask your clinician about primary care today!)
  2. Mental Health Intake: Clinicians will do a full assessment.

As a DIY first step, keep a log for two weeks, tracking:

  • Hours of direct sunlight exposure
  • Sleep/wake times
  • Mood patterns scoring 1–10

This information may help you see some patterns you can try changing and will be good information when meeting with your provider.

Your Daily SAD Coping Toolkit

  1. Grounding 5-4-3-2-1: Name 5 things you see, 4 you touch, 3 you hear, 2 you smell, 1 you taste. Pulls amygdala offline in 90 seconds.
  2. Micro-wins: Make bed → 1 point. Shower → 2 points. Text a friend → 3 points. Gamify the slump!
  3. Future-trip dopamine: Having a plan in the future to look forward to is a great way to add some hope and excitement into our lives and reminds us that this, too, is temporary.
  4. Self-care isn’t always bubble baths: it could look like texting your battle buddy, “Rough day, call me?”

Prevention Starts early

  • Order a Happy Light
  • Stock up on D3
  • Schedule “winter buddy” check-ins with someone you trust.
  • Meal-prep high-protein breakfasts; blood-sugar crashes can worsen your mood.

Seasonal Affective Disorder is common, predictable, and, most importantly, treatable. The same brain that dims in November can ignite again with the right light, movement, and support.

Take one step today

  1. Schedule an intake with Alaska Behavioral Health
  2. Borrow a happy light (or ask your clinician where you can get one)
  3. Join a CBT group → Our Cohen Clinic offers a Veteran cohort (Call 907-762-8668 to get started)
  4. Share this post with someone who “just isn’t themselves” this winter.
