Seasonal Affective Disorder in Edmonton: Coping With Winter Depression

Seasonal affective disorder (SAD) is a type of depression that follows a seasonal pattern, usually starting in late fall and lifting in spring. In Edmonton, where midwinter days have fewer than eight hours of daylight, many people notice lower energy and mood. SAD goes beyond the winter blues: it brings weeks of low mood, oversleeping, carbohydrate cravings, withdrawal and difficulty functioning. Light therapy, counselling such as CBT, daily routines and, for some people, medication can make a real difference.

Signs of seasonal affective disorder

• Low mood most of the day, nearly every day, for weeks
• Loss of interest in activities you usually enjoy
• Sleeping much more and still feeling tired
• Craving carbohydrates and gaining weight
• Withdrawing from friends and family, “hibernating”
• Trouble concentrating and feeling heavy or slowed down
• Feelings of hopelessness or worthlessness

The key feature is the pattern: symptoms return around the same time each year and ease when daylight increases.

Winter blues vs SAD

Many Albertans feel a bit flatter in winter. That is normal. The winter blues are mild, come and go, and do not stop you working, parenting or enjoying life. SAD is more intense, lasts weeks and makes everyday life feel like a struggle. If you are unsure, a doctor or counsellor can help you tell the difference.

Why it happens

Shorter days and less sunlight can disrupt your body clock, lower serotonin and increase melatonin, affecting mood, sleep and energy. Cold weather, slippery roads and darkness also reduce activity and social contact, which can deepen low mood. Newcomers from warmer, sunnier countries may find their first Edmonton winters especially hard.

What helps

Light therapy

Using a bright light box, commonly 10,000 lux for about 20 to 30 minutes each morning, is a well-researched treatment for SAD. Speak with your doctor before starting, especially if you have eye problems, take medications that increase light sensitivity, or have a history of bipolar disorder.

Counselling

CBT adapted for SAD helps you notice winter-related thinking patterns, such as “there is no point doing anything until spring,” and plan activities that protect your mood. Research suggests its benefits may last into following winters.

Daily habits

1. Get outside in daylight, ideally in the morning, even on cloudy days
2. Keep a regular sleep and wake time, even on weekends
3. Move your body, indoors or out, such as a mall walk or a recreation centre
4. Plan social contact, weekly calls, coffee or classes
5. Schedule enjoyable activities in advance, so winter has things to look forward to
6. Eat regular, balanced meals and limit alcohol

Medication

For moderate to severe SAD, a doctor may recommend antidepressant medication, sometimes starting before symptoms usually begin.

Plan ahead for winter

If you know winter is hard, start in September or October: set up your light box, book counselling, plan activities and tell someone you trust what to watch for.

When to get help

Talk to a doctor or counsellor if low mood lasts more than two weeks, affects work or relationships, or comes with thoughts of hopelessness. If you are thinking about suicide, call or text 9-8-8 or call 911.
