As the days grow shorter and the temperatures drop, many people notice a change in their mood and energy. You might find yourself feeling more tired, less motivated, or simply “off” as winter settles in. While it’s normal to have fluctuations in mood throughout the year, for some, these seasonal changes bring more than just a case of the “winter blues.”

This pattern of mood changes is known as Seasonal Affective Disorder (SAD)—a type of depression that typically begins in the fall and continues through the winter months. Understanding what SAD is, why it happens, and how therapy can help are important steps toward feeling more balanced and hopeful, even during the darker days of the year.

What Is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder is a form of depression that occurs at the same time each year, most commonly during late fall and winter. People with SAD experience many of the same symptoms as major depressive disorder, but these symptoms follow a predictable seasonal pattern.

Some of the most common symptoms include:

• Persistent sadness or low mood

• Loss of interest in activities once enjoyed

• Fatigue or low energy

• Difficulty concentrating

• Increased sleep or changes in sleep patterns

• Changes in appetite, particularly craving carbohydrates

• Feelings of hopelessness or worthlessness

For some, symptoms are mild and may be brushed off as “winter sluggishness.” But for others, SAD can deeply affect daily functioning, work performance, and relationships. The important thing to know is that SAD is treatable, and you don’t have to simply wait for spring to feel better.

Why Does Seasonal Affective Disorder Happen?

Researchers believe that SAD is linked to changes in light exposure during the fall and winter months. Less sunlight affects the body’s internal clock (circadian rhythm), disrupting sleep patterns, mood regulation, and energy levels.

Here are a few biological factors that may contribute to SAD:

1. Reduced Sunlight and Serotonin Levels Sunlight helps regulate serotonin, a neurotransmitter that contributes to feelings of well-being and happiness. With shorter days and longer nights, serotonin production can drop, increasing the risk of depression.

2. Changes in Melatonin The hormone melatonin, which regulates sleep, is influenced by light exposure. In the darker months, melatonin production can increase, leading to feelings of drowsiness and fatigue.

3. Vitamin D Deficiency Less sunlight also means less vitamin D production, which has been linked to both mood and energy regulation.

4. Disrupted Circadian Rhythm Your internal biological clock adjusts to light and darkness. When daylight decreases, your body’s rhythm can shift out of sync, affecting sleep, appetite, and overall mood stability.

While the biological causes are clear, there are also psychological and environmental factors that can worsen symptoms. The holiday season can bring stress or loneliness, and cold weather may limit outdoor activity and social connection—both of which are vital for mental health.

Who Is Most Affected by SAD?

SAD can affect anyone, but certain factors may increase your risk:

• Geographic location: People living farther from the equator, where daylight hours are shorter, are more likely to experience SAD.

• Gender: Women are diagnosed with SAD more often than men.

• Age: Young adults are more commonly affected, though it can occur at any age.

• Personal or family history: Those with a history of depression or bipolar disorder are at higher risk.

Even if you’ve never experienced depression before, the seasonal pattern of light reduction can trigger changes in mood that are difficult to ignore.

Normalizing the Winter Blues

Feeling down or sluggish during the winter is common, and you’re not alone if your motivation or energy dips this time of year. Society often emphasizes productivity and positivity, even when our environment naturally slows us down.

It’s important to normalize these shifts while also recognizing when they cross the line from “winter blues” into something more serious. Occasional tiredness or irritability might be manageable with self-care, but ongoing sadness, loss of interest, or difficulty functioning may indicate that professional help could make a real difference.

At Silver Lining Counseling, we remind clients that seeking support isn’t a sign of weakness—it’s a sign of awareness. Acknowledging what’s happening is the first step toward feeling better.

Therapy Can Help with Seasonal Affective Disorder

Therapy offers practical tools and emotional support for managing Seasonal Affective Disorder. While light therapy and medication are sometimes part of treatment, counseling provides the space to explore how SAD affects your life and develop strategies to manage symptoms.

Here are some ways therapy can help:

1. Identifying Thought Patterns

Depression often brings negative or distorted thinking. Cognitive-behavioral therapy (CBT), for example, helps you identify unhelpful thought patterns and replace them with more balanced and realistic perspectives.

2. Developing Coping Strategies

Therapists can help you create a winter wellness plan—one that includes realistic goals, daily structure, self-care routines, and strategies for staying connected and active.

3. Addressing Underlying Stressors

Sometimes SAD can amplify existing challenges such as work stress, relationship struggles, or burnout. Therapy offers a supportive environment to process these issues and strengthen your emotional resilience.

4. Building Emotional Awareness

Learning to recognize your triggers—such as shorter days, isolation, or fatigue—helps you respond early before symptoms intensify.

5. Exploring Lifestyle Changes

Your therapist may also guide you in making practical adjustments, such as integrating light exposure, exercise, mindfulness, or creative outlets that boost mood.

The key is to remember that you don’t have to face SAD alone. A therapist can help you navigate seasonal depression in a way that fits your unique circumstances, personality, and goals.

Self-Care Tips for Managing SAD

In addition to therapy, there are evidence-based lifestyle changes that can help you feel more balanced through the winter months:

1. Maximize Natural Light Open curtains, sit near windows, and spend time outdoors during daylight hours. Even a brief walk outside can help regulate mood and energy.

2. Consider Light Therapy Light therapy boxes mimic natural sunlight and can help restore your body’s internal rhythm. Talk with your therapist or healthcare provider before starting.

3. Stay Active Regular movement—even light exercise like yoga or walking—releases endorphins and supports overall mental health.

4. Maintain Routine Keep consistent sleep and wake times, balanced meals, and scheduled activities to reduce feelings of stagnation.

5. Stay Connected Winter can make isolation tempting. Make an effort to connect with friends, family, or support groups, even virtually.

6. Practice Mindfulness Meditation, journaling, or gratitude practices can help you stay grounded and manage anxious or negative thoughts.

7. Seek Professional Help If your symptoms persist or worsen, don’t hesitate to reach out for support. Therapy can help you regain a sense of control and hope.
