If you feel noticeably worse every November and better again by April, that’s not a coincidence. And it’s not just “the winter blues.”
Seasonal Affective Disorder is a real subtype of depression tied to the calendar. Symptoms typically build through late fall and winter, then lift on their own by spring. The leading theory ties it to shrinking daylight, which throws off your circadian rhythm, shifts melatonin production, and can lower serotonin activity, three systems that all affect mood and sleep at once.
What It Tends to Look Like
- Persistent low mood
- Sleeping far more than usual, and still feeling tired
- Craving carbs
- Losing interest in things you’d normally enjoy
- Trouble concentrating
Some people get a summer version instead, insomnia and restlessness during long, hot days, but winter-pattern SAD is far more common here in New England.
The line between a rough season and something worth addressing is mostly about duration and function. Feeling a little slower in January is normal. Weeks of it, or a stretch where you can’t keep up at work or with people you care about, is worth taking seriously.
What Helps
- Get morning light outside. Even on cloudy days, it does more to reset your internal clock than light later in the day.
- Try a light therapy box. Used consistently each morning, it helps a lot of people with SAD specifically.
- Exercise. It raises serotonin and endorphins directly, a short walk counts.
- Keep a consistent sleep schedule. It matters more than people expect when your body’s own cues are working against you.
- Don’t isolate. Even when staying in feels easier, disconnection tends to deepen low mood rather than rest it.
If the season is hitting you harder than it should, you don’t have to just wait it out. Our therapists can help you figure out whether what you’re feeling is seasonal, something more, or both, and build a plan that actually fits. Reach out to schedule an appointment.
