As leaves fall and winter approaches, many welcome the season with cozy sweaters, warm drinks, and holiday festivities. Yet, for a significant portion of the population, the changing seasons bring more than just a shift in wardrobe and activities – they herald the onset of Seasonal Affective Disorder (SAD), commonly known as seasonal depression. This article dives deep into the intricacies of SAD, shedding light on its causes, symptoms, and the myriad ways one can combat it.


Understanding Seasonal Affective Disorder (SAD)

SAD is a subtype of major depression, cyclical in nature, corresponding with the changing seasons. Most commonly, symptoms start in the late fall, continuing through winter, and begin to diminish with the onset of spring and summer. However, a less common variant emerges in the summertime, waning with the arrival of fall.




What Causes SAD?

While the exact causes remain unclear, several factors play a role:


Circadian Rhythm Disruption: The reduced sunlight in fall and winter can lead to a disruption in the body's internal clock, leading to feelings of depression.


Serotonin Drop: Reduced sunlight can cause a drop in serotonin, a neurotransmitter that impacts mood, leading to depression.


Melatonin Levels Alteration: The change in seasons can affect melatonin levels, impacting mood and sleep patterns.


Recognizing the Symptoms

Symptoms of winter-pattern SAD include:

  • Over-sleeping

  • Appetite changes, especially craving foods high in carbohydrates

  • Weight gain

  • Fatigue

  • Social withdrawal

In contrast, symptoms of summer-pattern SAD might entail:

  • Insomnia

  • Loss of appetite

  • Weight loss

  • Anxiety

  • Agitation

Combatting Seasonal Depression


Light Therapy: Also called phototherapy, this involves sitting close to a lightbox that mimics natural sunlight. It's been shown to cause a change in brain chemicals linked to mood and is often recommended as a first-line treatment.


Psychotherapy: Cognitive-behavioral therapy tailored to SAD can be beneficial. This involves identifying negative thoughts and replacing them with more positive ones, along with increasing light exposure.


Medication: Some people benefit from antidepressant treatment, especially if symptoms are severe. Doctors might recommend starting treatment before symptoms typically begin each year.


Vitamin D: While research is still ongoing, there's some evidence to suggest that Vitamin D can help regulate mood and ward off depression.


Maintain a Schedule: Keeping a regular schedule, waking up, eating, exercising, and going to bed at consistent times can help manage symptoms.


Stay Active: Regular physical activity can help counteract the symptoms of SAD. Consider indoor activities like yoga or swimming if it's too cold or dark outside.


The Interplay of Mind and Environment

While everyone may occasionally feel down as the days get shorter and darker, it's essential to distinguish between transient feelings and the persistent symptoms of SAD. Just as our environment undergoes a transformation with the changing seasons, our minds, influenced by myriad external and internal factors, undergo a shift.



Seasonal depression, with its cyclical appearance, can be disheartening. Yet, understanding its mechanisms and being proactive in seeking treatment can make a significant difference. As the seasons ebb and flow, so too can our spirits rise and fall. But with the right knowledge and tools, we can weather even the coldest winter, finding warmth not just in the world around us but within ourselves. If you believe you or a loved one is experiencing SAD, it's essential to reach out for professional help.
