Managing Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder (SAD) is a form of depression occurring in individuals with a seasonal pattern. SAD usually emerges in fall or winter and goes away with the arrival of spring. It usually occurs as a response to shorter days and reduced daylight in winter. Seasonal affective disorder affects feelings,? thinking, and behavior too. SADS should not be confused with “winter blues” as it has a deeper impact on lives. This disorder was first recognized in the early 1980s, with light therapy, and antidepressants, as its effective treatments. In some rare cases, people experience SAD during the summer, though this is far less common.

The occurrence of SAD is usually in adulthood. Between 18 to 30 age group. It is seen that its intensity keeps on increasing with time. Women are more prone to SAD than men. While it can begin at any age, SAD is rare in people under 20. Those living in northern regions with longer, darker winters, such as Alaska and New England, are at a higher risk of experiencing this seasonal depression.

Causes of Seasonal Affective Disorder (SAD)

• Around winter when lack of sunlight for days, SAD can prevail as by then the brain functioning gets disrupted.
• The hypothalamus, a brain region affected by sunlight, may not function properly due to reduced light exposure. This can lead to:
• Sunlight helps regulate the body's internal clock or circadian rhythm. Shorter daylight hours can throw off this rhythm while affecting sleep patterns and mood.
• There may be a genetic predisposition to SAD, as some people may be more vulnerable to the disorder due to running in families.
• A reduction in sunlight can shift the biological clock, which usually functions to govern mood, sleep, and hormone levels. It is then difficult for individuals to adjust to the seasonal changes in daylight.
• The neurotransmitter serotonin, which contributes to feelings of happiness often becomes imbalanced due to less sunlight. This can cause symptoms of depression.
• Sunlight is crucial for the production of vitamin D, which boosts serotonin levels. Reduced sunlight in winter can lead to vitamin D deficiency which will then negatively impact mood.
• People with winter-pattern SAD may experience an overproduction of melatonin. This leads to excessive sleepiness. Conversely, summer-pattern SAD may involve lower melatonin levels also affecting sleep quality.
• Stress and negative thoughts about winter or summer’s limitations might contribute to SAD. Although it’s unclear whether these thoughts are a cause or a result of the disorder.

5. The GP will mark the seasons for the occurrence of the symptoms, eg, winter or summer for at least two consecutive years, and also if the symptoms are more frequent during these periods than in other times of the year.

Managing Seasonal Affective Disorder SAD

1. Light Therapy Light therapy is one of the most common treatments for winter-pattern SAD. In light therapy, a person has to present themselves in front of a light-emitting box and intake around 10,000 lux for about 30 minutes every day. The light mimics natural sunlight and so stimulates serotonin production and reduces melatonin levels which then improves mood and sleep patterns. Light therapy is most effective when done in the morning. However, those with certain eye conditions or on medications that increase light sensitivity should consult a healthcare provider before starting.

2. Cognitive Behavioral Therapy (CBT) CBT, especially CBT-SAD, is a widely recommended talk therapy for SAD. It helps individuals channel their negative thought patterns related to the season. It then replaces them with more positive perspectives. CBT also involves behavioral activation where people are encouraged to develop new behaviors like bringing enjoyment and social interaction in every season. Studies show that CBT can provide long-lasting relief and is one of the best treatments for SAD.

3. Antidepressants Selective serotonin reuptake inhibitors (SSRIs) are often prescribed for SAD in situations when symptoms are more severe. These inhibitors work by increasing the serotonin level in the brain which reduces depression. Antidepressants like bupropion are taken daily, starting in the fall and continuing through the winter months. It’s important to note that SSRIs can take several weeks to show results and should be used under medical supervision due to potential side effects like gastrointestinal discomfort or sleep disturbances.

4. Vitamin D Supplementation People with winter-pattern SAD often have low levels of vitamin D due to reduced sun exposure. So, Taking vitamin D supplements can help improve mood and reduce fatigue. Supplementation should be done under guidance from a healthcare provider to avoid overconsumption.
