As the days get shorter and the holiday season ramps up, it’s completely normal to feel a shift in your mood. For many people, winter brings extra stress, emotional fatigue, or a bit of sadness, often called the “holiday blues.” But for others, the lack of sunlight and seasonal changes can trigger something more serious: Seasonal Affective Disorder (SAD), a form of depression that follows a yearly pattern.

Understanding the difference can help you get the right support and feel more in control during this time of year.

What Are the Holiday Blues?

The “holiday blues” are typically temporary and connected to the pressures of the season — travel, spending, family dynamics, loneliness, or simply too much on your plate.

Common signs:

  • Feeling overwhelmed or anxious
  • Low energy or irritability
  • Missing loved ones more than usual
  • Mood dips that improve once the busy season passes

The key thing: holiday blues come and go based on what’s happening around you.

What Is Seasonal Depression (SAD)?

Seasonal Affective Disorder is a recurring mental health condition tied to biological changes, especially reduced sunlight in fall and winter. It affects mood at a deeper level and tends to return each year.

Common symptoms:

  • Persistent sadness or hopelessness
  • Sleeping much more than usual
  • Loss of interest in things you normally enjoy
  • Carbohydrate cravings or appetite changes
  • Difficulty concentrating for weeks at a time
  • Pulling away from friends and activities

SAD is not just a stressful week, it lasts at least several weeks and impacts day-to-day functioning.

How to Tell the Difference

A simple rule of thumb:

Holiday Blues: temporary, event-related, and typically ease when stressors do
Seasonal Depression: lasts longer, returns yearly, and affects daily life

If your symptoms feel heavy, persistent, or disruptive, you don’t have to wait it out.

How to Support Your Mental Health This Season

Small, steady habits can make a big difference:

  • Get morning sunlight or use a light therapy lamp
  • Move your body daily, even a short walk brightens mood
  • Stick to routines for sleep and meals
  • Stay socially connected (even virtually!)
  • Talk to someone, especially if emotions feel overwhelming

You are not supposed to handle everything alone. Support matters.

The Bottom Line

Your feelings are valid and they deserve attention.
If the season feels heavier than expected, reaching out is a strong and healthy first step.
