Seasonal Affective Disorder

Seasonal Affective Disorder Treatment in Biddeford, Maine

As the daylight fades and Maine settles into long winters, many people notice a shift—not just in the weather, but in their mood. Seasonal Affective Disorder (SAD) is more than “winter blues.” It’s a treatable form of depression that follows a seasonal pattern, often beginning in late fall and easing in spring.

At Portland Treatment in Biddeford, Maine, we help clients understand why these mood changes happen and provide effective, evidence-based treatment to restore energy, motivation, and emotional stability during darker months.

What Is Seasonal Affective Disorder?

SAD is a type of major depressive disorder with a recurring seasonal pattern. It typically appears when daylight decreases, affecting the brain’s regulation of:

  • Serotonin (mood stability)
  • Melatonin (sleep–wake cycles)
  • Circadian rhythm (body clock)

Because Maine is farther north and experiences sharp seasonal daylight changes, residents here are at a much higher risk of SAD than in many parts of the country.

Common Symptoms of SAD

Symptoms can range from mild to severe and often include:

  • Low mood or irritability
  • Persistent fatigue
  • Increased sleep (or difficulty waking up)
  • Overeating or carbohydrate cravings
  • Social withdrawal or loss of interest
  • Difficulty concentrating
  • Feeling slowed down, heavy, or unmotivated
  • Hopelessness or overwhelming sadness

If symptoms return year after year, SAD is a likely cause, and professional treatment can make a huge difference.

Why Seasonal Changes Hit So Hard in Maine

Maine’s unique climate creates several SAD-triggering conditions:

  • Short daylight hours during fall and winter
  • Cloud cover and long periods of low sunlight
  • Cold weather limiting outdoor activity
  • Disrupted circadian rhythms
  • Isolation from reduced social activity

At Portland Treatment, we understand how these factors compound mental health symptoms and build treatment plans tailored to Maine’s seasonal realities.

How Portland Treatment Helps: Effective Treatment for SAD

Our approach addresses both the biological and emotional roots of Seasonal Affective Disorder.

Light Therapy (Bright Light Exposure)

Light therapy is one of the fastest-acting and most evidence-supported treatments for SAD.
It helps regulate melatonin, boost serotonin, and reset circadian rhythms.

Clients receive guidance on:

  • The correct type of light box (10,000 lux)
  • Safe distance and daily timing
  • How to integrate light exposure into morning routines

Our clinicians walk clients through usage so treatment is safe, consistent, and effective.

Cognitive Behavioral Therapy for Seasonal Patterns (CBT-SP)

CBT-SP is a specialized form of therapy that targets:

  • Negative thought patterns that worsen during winter
  • Behavioral withdrawal and inactivity
  • Seasonal triggers and stressors
  • Loss of structure or routine

Clients develop skills to break “winter depression cycles” before they take hold.

Medication Management (When Appropriate)

For some, antidepressant medication, especially SSRIs or SNRIs, helps stabilize mood during seasonal episodes.

Our psychiatric providers offer:

  • Thorough assessments
  • Medication evaluation
  • Ongoing monitoring
  • Seasonal planning (pre-winter adjustments if needed)

This ensures treatment is safe, personalized, and effective.

Vitamin D & Lifestyle Support

Low sunlight often correlates with low vitamin D levels, which can worsen depressive symptoms.

We help clients:

  • Monitor vitamin D levels with their providers
  • Optimize nutrition during winter months
  • Build routines that support energy and mood
  • Reintroduce outdoor activity, even in colder weather

Holistic changes amplify therapeutic progress.

Treatment for Co-Occurring Concerns

SAD often overlaps with:

  • Anxiety
  • Trauma responses
  • Substance use
  • Insomnia
  • Chronic stress

Portland Treatment addresses all contributing factors to ensure long-term relief—not just seasonal symptom management.

When to Seek Help

You may benefit from Seasonal Affective Disorder treatment if:

  • Depression appears the same time each year
  • Fatigue or sleep changes disrupt your routine
  • You withdraw from friends or activities
  • Your motivation drops drastically in fall or winter
  • You rely on alcohol or substances to cope
  • Mood changes impact work, school, or relationships

SAD is highly treatable—and symptoms often improve quickly with the right plan.
