The Loneliest Time of the Year? Here’s How to Survive SAD 

Seasonal affective disorder (SAD)

Holiday Depression

If you’ve found yourself dreading the 5 p.m. darkness and are struggling to feel motivated to do everyday life, you’re experiencing what many people wrestle with every winter. With this time of year comes the holiday season, which is supposed to be about connection, joy, and celebration. But for many, it feels more like a slog marked by exhaustion, emotional withdrawal, and a sense of emptiness.

Winter can be hard on your mental health, and the cultural pressure to be festive and grateful can make that struggle even heavier. When everyone around you seems to be thriving while you’re struggling emotionally, it’s easy to believe something is fundamentally wrong.

But the truth is more compassionate and nuanced: Your struggle isn’t a personal failing or a lack of willpower or gratitude.

Winter Mental Health Challenges: SAD Is More Than Just a Bad Mood

When the winter months feel difficult, it helps to really understand what’s going on from a scientific and biological perspective. The official term for “winter blues” is seasonal affective disorder (SAD), a type of depression prompted by a change in seasons, mainly fall and winter, when we experience less daylight and sunshine.

It significantly affects as many as 5% of people in the United States and 2-3% of people in Canada each year. But even if you don’t have a true SAD diagnosis, winter can still significantly impact your emotional well-being.

Those affected by winter blues may become more withdrawn, don’t eat as well, avoid going outside, and experience a low, dysthymic mood that leaves them not feeling like themselves. While these symptoms can vary from person to person, you don’t need to hit a clinical threshold for your experience to be valid or worthy of attention. If the holidays or winter in general, consistently makes life feel harder, cloudier, or lonelier, that’s enough reason to seek support and implement strategies that help.

Why Winter Hits Different: The Science Behind SAD and The Winter Blues

Winter blues is science: your body is responding to real environmental changes in predictable, biological ways. Researchers believe it’s connected to changes in light exposure that disrupt our circadian rhythm and neurotransmitter activity, especially serotonin and melatonin, which help regulate mood and sleep.

Through our eyes and through our skin, when we have exposure to daylight, our bodies create vitamin D from that sunlight, and that increases serotonin, which helps us balance our good feelings. When we don’t have that exposure to sunlight, our vitamin D levels go down, and therefore our serotonin goes down.

Plus, during the holidays, many people experience complicated feelings like grief over lost loved ones, stress about family dynamics and social commitments, financial anxiety, or more. These psychological stressors compound the biological struggles that winter already creates.

4 Ways to Protect Your Mental Health This Time of Year

When it comes to navigating SAD or winter blues, you don’t have to suck it up and get through it. Instead, try these behavioral strategies that can make this time of year not feel so heavy.

Create Structure When Your Brain Craves Hibernation

When your motivation disappears and everything feels effortful, structure becomes your friend. Prioritizing light exposure by getting outside or light machines, sticking to your daily routine, and maintaining social connections can make a meaningful difference when holiday chaos and winter cold feel overwhelming.

Consider the following:

• Setting a consistent wake-up time, even on weekends
• Planning one small task you accomplish each day
• Scheduling social commitments in advance (so you can’t talk yourself out of them later)
• Building in activities that historically bring you even mild enjoyment

The goal isn’t productivity for productivity’s sake. It’s preventing the downward spiral that happens when isolation, inactivity, and irregular routines feed depression.

Rethink Your Relationship With Light

Maximizing exposure to natural sunlight, especially for at least 20 minutes in the morning, is a simple and effective way to reduce SAD symptoms. But when it’s freezing outside, and you’re already feeling depleted, “just going outside” can feel like an impossible ask.

Instead, start smaller. Open your blinds as soon as you wake up. Move your workspace closer to a window. Take your coffee outside for five minutes, even if it’s cold. These aren’t cure-alls, but they’re practical steps that work with your reality rather than against it.

For some people, light therapy using a specialized light box can be helpful. Light therapy involves sitting near a specially designed light box for about 20-30 minutes each morning to help trick your body into responding as if there’s more daylight.

Stay Connected Even When You Want to Disappear

One of the biggest ironies of winter depression is that the time when you most need social support is when reaching out feels most difficult. Staying socially connected is an important way to manage symptoms of Seasonal Affective Disorder, even across physical distance.

You don’t need to force yourself into large gatherings or pretend to be cheerful when you’re not. Small, authentic connections are what matter. A text exchange with a friend, a brief phone call with a loved one, or committing to attend one social event per week, even for an hour, can help you stay connected with others. Making a plan to limit social time with those during the holidays who add stress, rather than calm, to your life is also a good way to ensure you build social connections without depleting your social battery.

Move Your Body Any Way You Can

Regular exercise can boost serotonin levels and improve mood, working wonders for your mental health. But working in physical activity doesn’t have to mean grueling gym sessions or outdoor runs in the cold. Here are a few accessible movement ideas that you can work into your routine:

• A 10-minute walk around your block
• Gentle stretching while watching TV
• Dancing while you cook in your kitchen
• Indoor workouts, such as yoga or home-based cardio exercises

When Self-Help Strategies Aren’t Enough: The Role of Therapy

Sometimes, no amount of light exposure, social connection, or routine-building is enough to get you through winter. That’s not a failure: you just may need more tailored support to help you navigate this season. The right therapist can provide exactly that.

What Therapy Offers That Self-Help Can’t

A therapist provides tips and techniques for addressing your mental needs, but they offer a space where your experience is heard without judgment, where patterns you can’t see on your own become visible, and where you can build personalized coping strategies tailored to your specific situation.

Cognitive Behavioural Therapy (CBT) has been shown to be particularly effective in treating Seasonal Affective Disorder. CBT helps you identify and challenge the thought patterns that keep you stuck (like “I’ll never feel better” or “something is wrong with me”) and replace them with more balanced, helpful perspectives.

Therapy is about reframing thoughts and understanding the full picture of what you’re dealing with. Depression often happens with other conditions, such as physical ones or other mood disorders, substance abuse, or anxiety. A trained therapist can help you understand how different factors in your life interact and affect your mental health.

How to Start the Therapy Conversation

At GoodTherapy, we know that making the step to ask for help can feel overwhelming. Knowing you need help is different than actually seeking it.

If this sounds like you, start by admitting this: “I need to talk about something I’ve been dealing with.” That’s it. You don’t need to have everything figured out or articulate your entire mental health history perfectly. A good therapist will help you find the words and understand what you’re experiencing. The sooner you reach out, the more tools you have to work with before symptoms intensify.

Don’t just talk to anyone, though: finding the right therapist matters, too. At GoodTherapy, our therapist quiz helps you find professionals based on specific concerns, treatment approaches, insurance, location, and availability. You can look for therapists who specialize in depression, seasonal affective disorder, and related mental health challenges. Someone who understands your experience can create a space where you feel heard and supported.
