If you're already dragging by 5 p.m., you're not imagining it. In an American Psychiatric Association poll, 41% of Americans said their mood declines in winter, about twice as many as said it improves (APA, 2024). And it's about to get darker faster. Daylight saving time ends Sunday, November 1, and the sun will set an hour earlier overnight. In the same poll, 29% said "falling back" hurts their mental health.
The good news: winter blues usually respond to small, ordinary changes. Here's what's going on and what to do about it.
What the Winter Blues Feel Like
The winter blues aren't a diagnosis. They're the flat, sluggish, harder-to-get-going feeling a lot of people get once the days shorten. In the APA poll, the most common winter changes people noticed were:
Women were more likely than men to say their mood dropped in winter (45% vs 37%), and the Midwest had it worst, at 52%. The upside: 61% said they feel better once spring comes.
Winter Blues vs Seasonal Affective Disorder
This is the line worth knowing. Seasonal affective disorder (SAD) is a type of depression that comes back at the same time each year, with symptoms that last about four to five months, according to the National Institute of Mental Health (NIMH).
The winter blues are milder. You feel lower than usual, but you can still work, see people and enjoy things.
SAD is more like this:
- A sad, anxious or "empty" mood most of the day, nearly every day, for at least two weeks
- Losing interest in things you used to enjoy
- Oversleeping and still feeling exhausted
- Strong carbohydrate cravings and weight gain
- Pulling away from people, the urge to "hibernate"
- Feeling hopeless, worthless or guilty
NIMH notes that SAD is tied to daylight, not the calendar, so it's different from holiday stress. It's more common in women and in people who live farther north. A diagnosis also requires the seasonal pattern to show up for at least two years in a row.
How to Beat the Winter Blues
None of this needs special gear or a new routine from scratch. The idea is to put back what shorter days quietly take away: light, movement, structure and people.
Get light early
Morning light is the big one. Go outside within an hour or so of waking, even when it's overcast. A walk, coffee on the porch, parking farther from the door. At home and at work, sit near a window when you can.
Light boxes are the clinical version of this. For SAD, NIMH describes a very bright box (10,000 lux) used for about 30 to 45 minutes, usually first thing in the morning, from fall to spring. If you're thinking about one, check with your provider first, especially if you have an eye condition or take medication that makes you sensitive to light.
Keep your wake-up time steady
Dark mornings make it tempting to sleep in, and sleeping more was the top winter change in the APA poll. But extra sleep often leaves you groggier, not rested. Getting up at the same time every day, weekends included, keeps your body clock anchored when daylight isn't doing that job. If sleep is already a struggle, our guide to sleeping better naturally has more.
Move, especially in daylight
You don't need a training plan. A 15-minute walk at lunch gets you light and movement at the same time, which is the best deal of the winter day. On bad-weather days, a few flights of stairs or a short video workout still counts.
Put good things on the calendar
When energy drops, the fun stuff goes first, and that makes the mood drop further. Therapists who treat SAD use a technique called behavioral activation: deliberately scheduling pleasant, engaging activities so they happen whether you feel like it or not (NIMH). Pick one thing a week to look forward to. A standing dinner, a class, a game night, a hike while it's still light out.
Stay close to your people
Talking with friends and family was the most popular way Americans coped with winter in the APA poll (46%). Winter makes it easy to cancel and stay in. Try to keep at least one in-person plan a week, and say yes more than feels natural.
Watch the story you tell yourself about winter
"I always fall apart in winter." "There's nothing to do until April." Thoughts like these make the season harder than it has to be. NIMH notes that CBT adapted for SAD works on replacing negative thoughts about the season, and in head-to-head research it worked as well as light therapy, with effects that seemed to last longer. You don't need a diagnosis to borrow the idea. Notice the thought, then ask whether it's actually true this year.
What About Vitamin D?
Your skin makes vitamin D from sunlight, so levels can dip in winter. NIMH says research on vitamin D as a SAD treatment is mixed: some studies found it helped as much as light therapy, others found no effect. Supplements can also interact with some medications. Ask your provider before you start one, and a simple blood test can tell you if you're actually low.
Build the Habits Before the Clocks Change
The best time to start is now, before November 1. Habits are easier to set up when you've still got some energy, and they carry you through the darkest weeks when motivation runs out.
That's what the Avidon app is built for. It uses cognitive behavioral techniques to help adults change everyday habits, with programs for Stress & Emotional Health, Sleep & Recovery, Mindset & Self-Talk, and Movement & Physical Activity. In our six-month study of more than 7,500 people who took our stress program, 96% said they handled stressful situations more effectively afterward.
