Understanding the signs of SAD and knowing when to seek help can make all the difference in managing your mental health this winter. AFC Cleveland is here to provide support and help you take the first steps toward feeling better.

What Is Seasonal Affective Disorder (SAD)?

Seasonal Affective Disorder is a form of depression that follows a seasonal pattern, most commonly appearing in the fall and winter months when daylight hours decrease. While it’s normal to feel a little sluggish during the colder months, SAD is more than just the “winter blues.” It’s a recognized medical condition that can significantly affect daily life, making it difficult to stay motivated, focus on work or school, or even enjoy activities you normally love.

Although SAD is most commonly associated with winter, a less common form, called summer-pattern SAD, occurs in the spring and summer, causing symptoms like insomnia, restlessness, and irritability.

How Do You Know If You Have SAD?

SAD symptoms closely resemble those of major depressive disorder, but they occur in a seasonal pattern. If you’ve noticed a shift in your mood and energy levels every winter, consider whether you’ve experienced any of the following symptoms:

  • Persistent sadness – Feeling down, hopeless, or empty most of the time
  • Loss of interest – Losing enjoyment in hobbies or activities you once loved
  • Fatigue – Constant exhaustion, even after a full night’s rest
  • Sleep changes – Difficulty waking up in the morning or sleeping excessively
  • Increased appetite – Craving carbohydrates and experiencing weight gain
  • Difficulty concentrating – Struggling to focus at work or school
  • Social withdrawal – Avoiding social activities or isolating yourself
  • Feelings of worthlessness – Increased self-doubt or feelings of hopelessness

If these symptoms sound familiar and tend to occur during the winter months, you may have SAD.

What Causes Seasonal Affective Disorder?

While the exact cause of SAD is still being studied, researchers believe several factors contribute to its onset:

  • Reduced sunlight exposure – Shorter days can disrupt your body’s internal clock (circadian rhythm), leading to mood disturbances.
  • Serotonin imbalances – Sunlight helps regulate serotonin, a brain chemical that affects mood. Lower serotonin levels in the winter can contribute to depression.
  • Melatonin disruption – Changing daylight hours can interfere with melatonin production, affecting sleep and mood regulation.

Treatment Options for Seasonal Affective Disorder

If you suspect you have SAD, the good news is that effective treatments are available. Here are some of the most common ways to manage symptoms and improve your well-being:

Light Therapy

One of the most effective treatments for SAD is light therapy, which involves sitting near a special light box that mimics natural sunlight. Regular exposure, usually 20–30 minutes per day,can help regulate your circadian rhythm and boost serotonin levels.

Cognitive Behavioral Therapy (CBT)

Cognitive Behavioral Therapy is a structured form of talk therapy that helps individuals identify and change negative thought patterns. Studies show that CBT is highly effective for SAD, equipping people with coping strategies to manage seasonal depression.

Medication

For individuals with severe or persistent symptoms, antidepressant medications such as Selective Serotonin Reuptake Inhibitors (SSRIs) may be prescribed. These medications help balance serotonin levels and improve mood during the winter months.

Lifestyle Adjustments

Making small lifestyle changes can also have a big impact on managing SAD symptoms:

  • Get outside – Even on cloudy days, spending time outdoors can provide exposure to natural light. Try a winter walk at the Cleveland Metroparks or another local trail.
  • Exercise regularly – Physical activity releases endorphins, which naturally boost mood and energy levels.
  • Maintain a healthy diet – Eating a well-balanced diet with plenty of fruits, vegetables, and protein can help stabilize your mood.
  • Stick to a sleep schedule – Going to bed and waking up at the same time each day supports a healthy sleep cycle.
