Could This Be More Than Just the Winter Blues?

Seasonal affective disorder is more than winter blues

As the days grow shorter and the temperature drops, many of us notice a shift in our mood and energy. Getting out of bed feels harder, motivation dips, and suddenly everything feels like a bit more effort than usual. We often brush this off as the winter blues — and for many people, that’s exactly what it is.

But for some, these seasonal changes can feel heavier, more persistent, and more disruptive. If you’ve ever wondered whether what you’re experiencing might be more than just a rough winter stretch, you’re not alone — and you’re not imagining it.

What Are the Winter Blues?

The “winter blues” is a common, informal term used to describe mild changes in mood and energy during the colder months. Reduced daylight, colder weather, and changes in routine can all play a role. Many people notice feeling a bit more sluggish, less motivated, or more inclined to hibernate — and for most, these feelings improve as the days lengthen and spring approaches.

A significant portion of people experience some form of winter-related mood change, particularly in northern climates where daylight hours are limited. While the winter blues can feel uncomfortable, they usually don’t significantly interfere with work, relationships, or daily functioning.

When It’s More Than the Winter Blues: Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder (SAD) is considered a more severe and persistent form of seasonal mood difficulty. It’s a type of depression that follows a seasonal pattern, most commonly beginning in late fall or early winter and easing in spring or summer.

Unlike the winter blues, SAD can have a noticeable impact on how you feel, think, and function day to day. Recognizing the symptoms is an important step toward understanding what’s going on and finding the right kind of support.

Common Symptoms of Seasonal Affective Disorder

Emotional Symptoms

• Persistent low mood or sadnessThis can feel like a heaviness that lingers most days, even when nothing particularly upsetting has happened. You may notice that joy feels muted or harder to access, and emotional lows feel deeper or more frequent than usual.

• Loss of interest or pleasureActivities that once brought comfort or excitement may now feel draining or unappealing. Even small pleasures — music, conversation, favourite routines — may not offer the same sense of enjoyment.

• Increased irritability or emotional sensitivityYou might feel more easily frustrated, tearful, or overwhelmed. Small stressors can feel disproportionately heavy, and your emotional bandwidth may feel much narrower than usual.

Physical Symptoms

• Low energy and fatigueEven after what seems like adequate sleep, you may wake up feeling exhausted. Everyday tasks can feel unusually effortful, leaving you feeling depleted early in the day.

• Changes in sleep patternsMany people with SAD find they are sleeping more than usual yet still feel unrefreshed. Dark winter mornings can make getting out of bed feel especially challenging.

• Changes in appetite or weightCravings for carbohydrates or comfort foods are common and may be accompanied by gradual weight gain. Food can become a way to seek comfort or energy when mood and motivation are low.

Cognitive Symptoms

• Difficulty concentrating or thinking clearlyYou may notice brain fog, slower thinking, or trouble staying focused. Tasks that require planning, decision-making, or sustained attention can feel surprisingly difficult.

• Negative or self-critical thoughtsYour inner dialogue may become harsher or more pessimistic. You might find yourself replaying mistakes, doubting yourself, or expecting the worst more often than usual.

• Feelings of hopelessnessThere can be a sense that things won’t improve, or that winter — emotionally or literally — will never end. Even when you logically know this isn’t true, the feeling itself can feel very convincing.

What Can Help?

The good news is that there are effective ways to support yourself through seasonal mood changes. You don’t need to do everything at once — small, intentional steps can make a meaningful difference over time.

Light Therapy

Light therapy involves exposure to a bright, specially designed light that mimics natural daylight. When choosing a light box, it’s important that it provides 10,000 lux of light. Lux is simply a measure of brightness — for comparison, a typical indoor room has about 100–500 lux, while a bright summer day outdoors can exceed 10,000 lux. This level of light is what signals to your brain that it’s daytime and helps regulate mood, energy, and sleep-wake cycles.

Light therapy is most effective when used in the morning, ideally shortly after waking, for about 20–30 minutes. Using a light box later in the day or in the evening is not recommended, as it can dysregulate your internal clock and make it harder to fall asleep at night. When used consistently and at the right time, many people notice gradual improvements in mood, alertness, and overall energy.

Engaging in Outdoor Activities (or Bringing the Light Indoors)

Spending time outdoors, even on cloudy or cold days, can be very beneficial, as natural daylight is still far brighter than indoor lighting. A short walk, gentle movement, or even a few minutes of fresh air can support both physical and emotional well-being.

For those for whom going outdoors isn’t feasible — whether due to harsh winter conditions, mobility concerns, or safety issues — there are still supportive alternatives. Engaging in physical activity inside your home with the curtains open can help maximize exposure to natural light. Sitting by a window during the brightest parts of the day, reading, stretching, or enjoying a warm drink can also be helpful. Even small amounts of light and movement can add up.

Staying Connected

When energy is low, it can be tempting to withdraw — but isolation often makes symptoms feel heavier. Reaching out to family, friends, or trusted supports, even in small ways, can help counter feelings of loneliness. A text message, a brief phone call, or sharing a meal can provide emotional grounding and remind you that you don’t have to navigate this alone.

Therapy and Medical Support

If symptoms feel intense, long-lasting, or are interfering with daily life, speaking with your doctor or a mental health professional is an important step. Treatments such as Cognitive Behavioural Therapy (CBT) have been shown to be effective for Seasonal Affective Disorder, helping people identify unhelpful thought patterns while building supportive routines and coping strategies.

Giving Yourself Permission to Go Slowly

Perhaps most importantly, be gentle with yourself. Winter can naturally be a season of lower energy, and that doesn’t mean you’re failing or falling behind. Give yourself permission to do a little bit at a time — one manageable task, one small act of care — rather than expecting yourself to function at full capacity.

A Final Thought

If you’re wondering whether what you’re experiencing might be more than just the winter blues, that curiosity itself is worth listening to. Paying attention to your mental health is not a weakness — it’s an act of care.

Support is available, and brighter days — both literally and emotionally — are possible.
