CBT for Seasonal Affective Disorder (SAD)

Educational content only. Discuss treatment options (including bright‑light therapy and medication) with a clinician. See our Medical Disclaimer.

Overview

SAD is characterized by seasonal patterns of depression, commonly in fall/winter. Reduced daylight, circadian shifts, and behavioral withdrawal can maintain low mood and energy.

Why CBT helps

Behavioral activation: pre‑plan energizing, daylight‑exposed, and social activities.
Cognitive strategies: identify winter‑related beliefs (e.g., “Nothing helps in winter”) and develop balanced alternatives.
Rhythm supports: consistent wake time, outdoor light exposure when feasible, and wind‑down routines.

Journaling prompts

Today’s daylight plan (time outside or near bright window): minutes and effect on mood/energy.
Activity completed despite low energy; mood before/after.
