Seasonal Affective Disorder: Coping During Dark Months

Seasonal Affective Disorder (SAD) manifests as recurrent depressive episodes in fall and winter, driven by reduced sunlight and circadian misalignment. SAD affects us in various ways. Clients report low energy, hypersomnia, carbohydrate cravings, and social withdrawal. Some helpful interventions can include strategies like light therapy, behavioral activation, and cognitive strategies within a therapeutic framework.

Light Therapy:

When the days grow shorter, our bodies get less natural sunlight, and for many, that change affects mood and energy. Light therapy offers a gentle way to mimic the benefits of natural sunlight. It typically involves sitting near a specially designed light box for about 20–30 minutes each morning. Over time, this exposure can help reset your body’s internal clock and improve serotonin levels, both of which can lift mood.

The key is to make it part of a consistent routine. Many people combine it with a quiet morning ritual like sipping tea, journaling, or simply breathing so it becomes a comforting start to the day rather than another “to-do.” Before starting, it’s best to check with a healthcare provider to ensure light therapy is safe and appropriate for you, especially if you have eye conditions or certain skin sensitivities.

Have limited opportunities to get outside? Daily exposure to a 10,000-lux light box for 20–30 minutes in the morning resets circadian rhythms and increases serotonin release. 

Behavioral Activation: 

When winter pulls you toward the couch and away from activities you enjoy, it’s easy to feel stuck in a low-energy loop. Behavioral activation is about gently nudging yourself back into small, meaningful actions even when motivation feels low. This could mean taking a short walk, calling a friend, or working on a hobby for just 10 minutes.

The idea isn’t to push yourself into doing “all the things,” but to choose small, manageable activities that you know lift your mood. Each time you follow through, you break the cycle of withdrawal and help your mind and body remember that movement, connection, and engagement feel good. Over time, those little steps can make a noticeable difference in how you feel during the darker months.

Scheduling enjoyable, mood-boosting activities outdoors such as brisk walks during daylight enhances natural light exposure and counters withdrawal. Keeping regular sleep–wake times also stabilizes your melatonin production.

Cognitive Techniques:

CBT for SAD targets negative winter‐related thoughts (“I hate these months, nothing will help”) by examining evidence and developing coping scripts (“I’ve used light therapy before and felt better”). Incorporating acceptance practices helps clients tolerate seasonal discomfort with self-compassion and helps up to reduce the harmful thinking patterns that may be keeping us stuck.

Additional strategies include:

  • Vitamin D Supplementation: Testing levels and supplementing (as guided by a medical professional) can address deficiencies linked to low mood.

  • Environmental Adjustments: Use full‐spectrum bulbs in key rooms, keep windows unobstructed, and sit near natural light sources.

  • Social Engagement: Group walks or community events during daylight hours provide both light and interpersonal support.

Integrated within depression treatment and emotional regulation services, this multi‐modal plan empowers clients to navigate seasonal shifts with evidence‐based tools and therapist guidance.
