The 4 Types of ADHD Explained

Quick Summary
- Seasonal Affective Disorder is a form of depression tied to the shift into winter, when reduced daylight disrupts the circadian rhythm along with serotonin and melatonin levels. Canada’s distance from the equator and coastal BC rain add to the risk.
- Symptoms run in two tracks: psychological ones like hopelessness, irritability, indecisiveness, and lost interest in things you used to enjoy, and physical ones including oversleeping, low energy, carbohydrate cravings, unexplained aches, and lowered libido.
- Light therapy sits at the front of treatment, using a light box that imitates daylight, ideally in the morning and built into a daily routine. Cognitive-behavioural therapy, outdoor time, steady sleep, exercise, and SSRIs for some people fill out the picture.
- Three signals point toward professional help: heavier reliance on escapism through screens, shopping, or substances; symptoms that deepen or drag on; and visible slipping at work, school, or in relationships. Burnout and winter low mood can look alike, so a clinician’s read helps.
The “Winter Blues”?
Winter months can be especially challenging for mental health, whether it is the accumulated stress of the holidays (including family or work stress) or the changes in season. If you or your loved ones have been struggling with workplace burnout before winter, you may see worsening mental health symptoms. It’s not easy to determine if you are experiencing workplace burnout or if it is a case of the winter blues, so this article serves to inform you of what to look for and when to seek support from a health professional.
As a clinical counsellor who works with professionals, high performers, and executives, I help individuals and couples in burnout recovery, and I provide treatments to individuals who are seeking to improve their Seasonal Affective Disorder. You can book a free virtual consultation with me if you have questions about your mental health, workplace burnout, or Seasonal Affective Disorder.
What is Seasonal Affective Disorder (The "Winter Blues)?
Seasonal Affective Disorder (SAD) is a type of depression that can occur during the winter months and is a medical condition. The seasonal shift to winter can cause a chemical change in the brain that leads to or worsens depressive symptoms. The end of daylight savings time, our geographical distance from the equator in Canada, and the rainy coastal weather here in BC can make it more difficult for our mental health.
Due to shorter days and less daylight, your biological clock (or circadian rhythm), serotonin levels, and melatonin levels can be disrupted, which increases the symptoms of depression and SAD.
Common SAD Symptoms
Common symptoms include persistent feelings of sadness, hopelessness, or low mood, often accompanied by fatigue or lack of energy that makes everyday tasks feel overwhelming. Individuals with SAD may experience changes in appetite, often craving carbohydrates, leading to weight gain, or they may lose interest in activities they once enjoyed. Other frequent symptoms include difficulty concentrating, irritability, and a tendency to oversleep (hypersomnia).
Physical symptoms such as body aches or a general sense of sluggishness may also be present. In some cases, SAD can exacerbate existing anxiety or depression, further intensifying the emotional toll. Find more symptoms below.

What Are the Treatment Options For Seasonal Affective Disorder?
Treatment options for SAD focus on alleviating symptoms and improving quality of life during the months when the condition is most prominent. One widely used treatment is light therapy, also known as phototherapy. This involves sitting near a specially designed light box that mimics natural sunlight, which can help regulate circadian rhythms and improve mood. Light therapy is often recommended for use in the morning and is most effective when incorporated into a daily routine.
In addition to light therapy, psychotherapy, particularly cognitive-behavioral therapy (CBT), has been shown to be effective in treating SAD. CBT helps individuals identify and modify negative thought patterns and behaviors associated with the condition, providing them with coping strategies to manage symptoms.
Other treatment approaches include lifestyle changes, such as spending more time outdoors during daylight hours, maintaining a consistent sleep schedule, and incorporating regular physical activity. For some individuals, healthcare providers may recommend antidepressant medications, particularly selective serotonin reuptake inhibitors (SSRIs), to help balance mood-regulating chemicals in the brain. A combination of these methods, tailored to individual needs, can offer significant relief from SAD symptoms.
When should I seek professional help for SAD?
- Increasing use of unhealthy methods of coping with stress. For example, the over-reliance on escapism, distraction or self-soothing through the excessive use of social media, TV, gaming, shopping, and substances (such as caffeine, nicotine, alcohol, cannabis, etc.).
- Worsening or prolonged symptoms
- Noticeable impairment towards your functioning in major life areas (ex: employment, education, family or life responsibilities, and relationships)
Frequently Asked Questions
How do I tell the difference between seasonal affective disorder and workplace burnout?
The two overlap heavily in fatigue, low motivation, and irritability, which is why self-diagnosis rarely settles it. Timing is one clue: SAD follows the seasonal shift and eases as daylight returns, while burnout tracks workload and ongoing stress. If burnout was already present going into winter, symptoms can worsen once the season turns. A clinical assessment separates them.
Why does living in British Columbia make winter depression more likely?
Canada’s distance from the equator means far less daylight through the winter, and coastal BC’s rainy weather cuts what light does reach the ground. The end of daylight savings time shortens usable evening light further. Less daylight disrupts your biological clock along with serotonin and melatonin levels, and that chemical change is what drives the drop in mood.
What time of day should I use a light box?
Morning use is the standard recommendation, and consistency matters more than the length of any single session. Light therapy works by mimicking natural sunlight to help regulate circadian rhythms, so building it into a daily routine produces better results than occasional use. Anyone considering it should confirm the approach with a healthcare provider first.
Do I have to take medication to treat SAD?
No. Light therapy, cognitive-behavioural therapy, and lifestyle changes such as daylight exposure, regular physical activity, and a consistent sleep schedule are all standard options. Antidepressants, usually SSRIs, are one path a healthcare provider may recommend when they suit the person’s situation. Most treatment plans combine several approaches, tailored to the individual, rather than relying on one.
Can seasonal affective disorder make anxiety or depression I already have worse?
Yes. SAD can intensify existing anxiety or depression, adding to the emotional toll rather than sitting separately from it. Someone already managing a mood condition may notice symptoms deepen as daylight shrinks. That overlap is worth raising with whoever is treating you, since it can change what kind of support makes sense over the winter.
Is craving carbs and sleeping more actually a symptom, or just normal winter behaviour?
Both can be true, but appetite changes and oversleeping are recognized symptoms of SAD rather than incidental habits. Carbohydrate cravings with weight gain, and hypersomnia, appear often enough to sit among the condition’s core signs. What separates a symptom from a seasonal habit is impact, particularly whether it interferes with work, relationships, or daily functioning.
