What is Seasonal Affective Disorder (SAD) and how can it be managed?

Seasonal Affective Disorder (SAD) is a form of recurrent depression that typically occurs during the colder, darker months of the year. It is more than just feeling “a bit low” in winter—it can cause significant changes in mood, energy levels, and overall functioning. People with SAD often experience symptoms beginning in late autumn or early winter, which then improve during spring or summer when daylight increases.

The exact cause of SAD is not entirely known, but several factors play a role. Reduced sunlight during winter months may disrupt the body’s biological clock, known as the circadian rhythm, leading to changes in sleep patterns and mood regulation. Low levels of sunlight also reduce serotonin—a neurotransmitter that affects mood—and increase melatonin production, a hormone responsible for sleep, leading to fatigue and lethargy.

Common symptoms of SAD include persistent sadness, low energy, excessive sleep, changes in appetite (especially craving carbohydrates), difficulty concentrating, and social withdrawal. Many individuals describe feeling “emotionally numb” or disconnected from daily activities. While it shares symptoms with other types of depression, its seasonal pattern distinguishes it.

Management of SAD involves both medical and lifestyle-based interventions. Light therapy (phototherapy) is often the first-line treatment. It involves sitting near a light box that mimics natural sunlight for about 20–30 minutes daily, which helps reset circadian rhythms and boosts serotonin levels. Cognitive Behavioral Therapy (CBT) also helps individuals identify and challenge negative thought patterns while developing coping strategies tailored to seasonal mood changes.

In some cases, antidepressant medications—especially SSRIs—are prescribed to stabilize mood. Alongside professional treatment, lifestyle changes such as spending time outdoors during daylight, maintaining a consistent sleep schedule, regular exercise, and a nutrient-rich diet are highly beneficial. Activities like yoga, mindfulness, and meditation also reduce stress and promote emotional balance.

Recognizing early warning signs—such as reduced motivation, oversleeping, or increased irritability—can help prevent severe episodes. SAD is a treatable condition, and with the right combination of therapy, medication, and self-care, individuals can regain their emotional stability and enjoy life year-round.
