• A. Exercise regimen
• B. Photo therapy
• C. Nutritional supplements
• D. Group therapy

Answer: (B)

Phototherapy is considered a common treatment for Seasonal Affective Disorder (SAD) because it directly addresses the condition's underlying cause, which is often related to changes in light exposure due to seasonal variations. This treatment involves exposure to a bright light that mimics natural sunlight, helping to regulate circadian rhythms and improve mood.

The effectiveness of phototherapy in managing symptoms of SAD has been supported by research, which indicates that it can lead to significant improvements in mood, sleep patterns, and overall functioning during the months when daylight is limited. This aligns with the concept that inadequate light exposure can lead to disruptions in neurotransmitters like serotonin, which are crucial for mood regulation.

While other treatments such as exercise, nutritional supplements, and group therapy may be beneficial for some individuals, phototherapy specifically targets the biological origins of SAD related to light exposure, making it a primary and widely recommended approach for managing this type of depression.
