The clocks just fell back. It's dark by 5 p.m., and suddenly everything takes more effort. Getting out of bed. Answering texts. Caring about anything at all.
A lot of people brush this off as the "winter blues." Sometimes that's all it is. But for some people, the shift in seasons brings on real depression, and it tends to come back year after year. If you notice a pattern, it's worth paying attention to.
What seasonal depression is
Seasonal depression, often called seasonal affective disorder or SAD, is depression that follows a seasonal pattern. For most people, it starts in late fall or early winter and lifts in spring or summer. Clinicians now usually describe it as depression "with a seasonal pattern."
Less daylight is thought to play a big role. Shorter days can throw off your body clock and affect brain chemicals like serotonin and melatonin, which help regulate mood and sleep. It's more common the farther you live from the equator, which includes us here in Pennsylvania and New York.
Winter blues or something more?
Feeling a little sluggish or wanting to stay in when it's cold and dark is normal. Seasonal depression is more than that. Signs can include:
Low mood most of the day, nearly every day
Losing interest in things you usually enjoy
Sleeping much more than usual and still feeling tired
Craving carbs and sweets, or gaining weight
Feeling heavy, slowed down, or low on energy
Pulling away from friends and family, sometimes called "hibernating"
Trouble concentrating
Feeling hopeless or worthless
The key clues are the pattern and the impact. If this happens around the same time each year, lasts more than a couple of weeks, and gets in the way of work, relationships, or daily life, it's more than the blues.
What can help
Seasonal depression is very treatable, and the earlier you start, the better. Options include:
Light therapy. Sitting near a special bright light box, usually for about 20 to 30 minutes each morning, can help reset your body clock and improve mood. Not all lamps are the same, so talk with a clinician about which kind to use and how. Light therapy isn't right for everyone, especially people with bipolar disorder or certain eye conditions.
Therapy. Cognitive behavioral therapy (CBT), including a version designed specifically for seasonal depression, can be very effective and may help prevent it from coming back.
Medication. Antidepressants can help. For people who get seasonal depression every year, sometimes we plan ahead and start treatment before symptoms usually begin.
Daily habits. Getting outside in daylight, especially in the morning, moving your body, keeping a regular sleep schedule, and staying connected with people all make a difference.
Some people also ask about vitamin D. Low levels are common in winter, but supplements alone aren't a proven treatment for seasonal depression. It's worth checking your levels with your primary care provider before adding supplements.
It's not just seasonal for everyone
Sometimes what looks like a winter slump is part of a bigger picture, like ongoing depression that gets worse in winter, or bipolar disorder, where mood can shift with the seasons in both directions. If your mood also swings unusually high in spring or summer, with less need for sleep, racing thoughts, or impulsive decisions, mention that to a clinician. It changes the treatment plan.
Don't wait for spring
It can be tempting to just push through until the days get longer. But that can mean four or five months of feeling awful, and it often comes back next year. You don't have to wait it out.
If this season is hitting you harder than it should, you can book an appointment or start with a free 15-minute consultation. Not sure what to expect? Here's what happens at a first psychiatric evaluation. You can also learn more about our services.
