Seasonal Depression 2.0: What This Winter Is Teaching Me as a Therapist (and How It Compares to Last Year)

Last winter, I wrote about Seasonal Affective Disorder (SAD) and the toll it can take when the world grows colder and darker. I talked about low mood, exhaustion, disrupted sleep, and how so many of us blame ourselves long before we recognize the seasonal patterns behind it.

(Check out my post from last year here: Understanding & Navigating Seasonal Affective Disorder)

This year, I’m finding myself returning to the topic again, but from a slightly different lens. Not because winter has changed (it’s as relentless as ever), but because we have. Research has evolved. Mental-health trends have shifted. And after another year of walking through this season alongside clients, I’ve noticed and learned more about what’s stayed consistent and what absolutely hasn’t.

Think of this as the 2025 updated, therapist-informed, lived-experience version of seasonal depression. The version shaped by stories from the therapy room, new data, and the quieter lessons winter teaches us when we’re willing to listen.


What Hasn’t Changed Since Last Year

1. Seasonal depression is still deeply biological, not a character flaw

Just like I wrote last winter, the core truth remains: seasonal depression isn’t a personal failure. Reduced daylight still disrupts:

  • Circadian rhythm
  • Serotonin levels
  • Melatonin production
  • Energy, appetite, and mood regulation

Clients still come into sessions asking important questions like, “Why do I constantly feel as if I’m running on empty?” and I still get to remind them: your body is responding to the environment, not abandoning you.

2. Light continues to be one of the most effective interventions

No trend cycle has changed this. Light therapy remains the gold standard for winter-pattern SAD. Morning light, whether from a sun lamp or actual sunshine, consistently helps regulate the body’s internal rhythms and lift mood.

The basics are still the basics for a reason.
And consistency still matters more than perfection.


If this conversation sparks some curiosity about how circadian rhythms work, and why light can be such a powerful part of healing winter heaviness, I encourage you to watch Dr. Satchin Panda’s TEDx talk. It’s one of the clearest explanations I’ve found, and it aligns beautifully with what I see in therapy every winter season.


What HAS Shifted This Year

1. The trend toward prevention instead of crisis response

One of the biggest differences I’ve noticed, both in research and in client behavior, is a move toward starting interventions earlier.

People aren’t waiting until January to admit they’re struggling. Many start light therapy in early fall, build routines pre-emptively, or begin tracking mood patterns ahead of time. This aligns beautifully with new data suggesting that the earlier we intervene, the fewer symptoms we end up facing.

2. A more personalized understanding of seasonal patterns

Last year, I wrote about seasonal depression as if winter were the only culprit. But with newer longitudinal research, we’re learning that not everyone’s mood dips peak in winter, and risk varies by sleep schedule, work patterns, genetics, and geography.

This year, my new focus is to help myself and my clients create individual seasonal profiles:

  • When their energy naturally dips
  • What their sleep does
  • Which symptoms show up first
  • Which tools help them bounce back

It’s no longer about “everyone feels worse in winter,” but rather, “What does YOUR seasonal landscape look like?”

If you’ve resonated with what I’ve described about seasonal depression and circadian disruption, but you’re not sure where you personally fall, you might find value in an online self‑assessment. The Center for Environmental Therapeutics offers free, confidential questionnaires to help you track:

  • Whether your mood and energy follow a seasonal pattern (which could signal seasonal depression)
  • Your natural “chronotype” (whether you’re more of a morning‑type “lark” or evening‑type “owl”) — which affects when light therapy is likely to be most effective
  • Current levels of depressive symptoms (a helpful baseline if you start therapy, light intervention, or other supports)

These tools aren’t a diagnosis, but they can give you a clearer, research‑informed picture of your rhythms and mental health. If you’re curious, you can check them out here: CET Self‑Assessments for Seasonal Pattern, Chronotype & Mood

3. A shift toward “micro-routines” instead of unrealistic self-care

Gone are the days of telling people to overhaul their entire lifestyle to improve their mood, because rarely does anybody have the capacity for that in January.

This year’s trend is small, sustainable anchors:

  • 5 minutes of morning light
  • A 3-minute stretch
  • One low-pressure check-in with a friend
  • A warm drink ritual
  • A short walk, even around the block

Micro-routines are not glamorous, but they’re doable. And the brain responds better to tiny consistency , rather than large, intermittent efforts.

4. A bigger emphasis on connection (even low-energy connection)

This winter, more clients are naming loneliness as a symptom of seasonal depression, not a side effect. And therapists everywhere are responding by emphasizing low-energy community:

  • Shared voice notes
  • Co-working sessions on Zoom
  • Weekly meme exchanges
  • Simple accountability texts

The trend is away from isolation, but also away from high-pressure socializing.
Somewhere in the middle — gentle connection — is where healing lives.


My Go-To Therapist Recommendations for This Winter

Here’s what I’m recommending most often this season, grounded in both research and what I’m seeing work in real time:

1. Begin light exposure early and consistently

Use a 10,000-lux lamp each morning for 20–30 minutes. When possible, start before symptoms peak.
For lab-tested lamp recommendations, check out Health’s “Best Light Therapy Lamps for Shorter Days”

2. Protect your circadian rhythm like your mood depends on it

Because it does.
Consistent sleep and wake times, dimmer evenings, brighter mornings.

3. Build micro-routines, not massive goals

Small, repeatable actions regulate the nervous system better than grand plans you can’t sustain.

4. Track your personal seasonal patterns

Not everyone’s mood dips the same way at the same time.
Know your cues.

5. Stay connected in low-pressure, energy-matched ways

Let winter be communal, not isolating.

6. Practice compassionate pacing

Winter often requires slower living, not because you’re weak, but because you’re rhythmic.


Final Thoughts: Looking Back, Looking Forward

When I compare this year’s winter to last year’s, it’s clear we’re moving toward a deeper, more compassionate understanding of seasonal depression. We’re blending science with lived experience. We’re shifting from “push through it” to “work with your rhythm.” And we’re learning to personalize, not pathologize, the seasonal changes our minds and bodies go through.

If you’re feeling the heaviness this season, you’re not alone.
You’re not failing.
You’re responding to real, physiological shifts, ones you can support with tools, awareness, and a whole lot of gentleness.

Winter may dim the world, but it doesn’t erase your light.
Not this year. Not any year.
