A patient diagnosed with circadian rhythm disorder should be recommended which therapy?

• A. Melatonin supplementation
• B. Bright light therapy in the evening
• C. Cognitive behavioral therapy
• D. Sleep hygiene education

Answer: (B)

Bright light therapy in the evening is particularly effective for patients with circadian rhythm disorders, as it helps to reset the body's internal clock. This therapy involves exposure to bright light during the evening hours, which can shift the timing of the circadian rhythms. It is commonly used for conditions such as delayed sleep phase disorder, where individuals find it difficult to fall asleep until late at night and struggle to wake up in the morning. In this context, bright light therapy works by promoting alertness when it is needed most, thereby facilitating an adjustment in the sleep-wake cycle. This can help align the individual's schedule with societal norms, reducing symptoms of the disorder. While other therapies mentioned also play a role in managing sleep issues, bright light therapy specifically targets the underlying biological mechanisms of circadian rhythm disorders, making it the most appropriate recommendation for this condition.
