Seasonal depression, also known as seasonal affective disorder, is a form of clinical depression with symptoms similar to major depression and affects up to one in 10 people, more commonly women.
Seasonal depression is influenced by changes in the body's circadian rhythm, such as disrupted sleep patterns from lack of sunlight and increased melatonin release, resulting in fatigue and grogginess.

Understanding Seasonal Depression
Seasonal depression, also known as seasonal affective disorder, is a type of depression that is related to changes in seasons. It typically starts in autumn and continues into the winter months. This disorder is not just the winter blues, but a form of clinical depression with similar symptoms to major depression. It affects up to one in 10 people and is more common in women. Interestingly, some individuals experience reverse seasonal affective disorder, feeling depressed during the summer months. The disorder is caused by changes in the body's circadian rhythm and the release of hormones like melatonin and serotonin. Lack of exposure to sunlight and outdoor activities can contribute to the symptoms. To manage seasonal depression, treatments like bright light therapy, cognitive behavioral therapy, and antidepressant medication can be effective. Making lifestyle changes, such as spending time outdoors, replacing summer activities with winter-friendly alternatives, and planning for future events, can also help improve symptoms.
The Science Behind Seasonal Depression
Seasonal depression is influenced by the body's circadian rhythm or internal body clock. Changes in sunlight and daylight hours disrupt this rhythm, leading to mood shifts. Melatonin, a hormone released in response to darkness, peaks earlier during the winter months, causing fatigue and grogginess. Serotonin, known as the happy hormone, is also implicated in seasonal depression. It plays a role in mood regulation, and lower levels can contribute to depressive symptoms. Being indoors for extended periods without natural light and the inability to engage in activities that bring joy worsens the condition. Understanding the science behind seasonal depression helps explain why it occurs and how it affects mood and well-being.
Managing Seasonal Depression
Various strategies can help manage seasonal depression. Bright light therapy, which involves exposure to artificial light that mimics natural sunlight, helps resynchronize the body's sleep patterns and improve mood. Cognitive behavioral therapy can challenge negative thoughts and associations with the winter months, shifting perception and promoting well-being. Antidepressant medication, such as selective serotonin reuptake inhibitors, may be prescribed to regulate serotonin levels and alleviate symptoms. Additionally, making lifestyle adjustments like spending time outdoors, pursuing winter-friendly activities, planning future events, and seeking warmer and sunnier environments can also provide relief. It is important to remember that seasonal depression is not one's fault, and seeking support and treatment can make a significant difference in managing symptoms.
With many of us entering the colder, winter months, understanding what seasonal depression is and how it impacts our mood, energy levels, appetite and mental well-being is crucial. This week we break down the science and psychology behind seasonal affective disorder and how we can overcome the ‘winter blues’ brought on by the colder months.
