Which of the following is NOT a recommended intervention for improving sleep in depressed clients?

Prolonged screen time before bed is not a recommended intervention for improving sleep in depressed clients due to its potential negative impact on sleep quality. The blue light emitted by screens can interfere with the body's natural circadian rhythms, making it difficult for individuals to fall asleep and negatively affecting overall sleep health.

In contrast, interventions such as structured daily routines, regular physical activity, and increased engagement in soothing activities are all known to facilitate better sleep. Structured routines help regulate the sleep-wake cycle, regular exercise can reduce symptoms of depression and improve sleep quality, and soothing activities promote relaxation, making it easier to wind down before bedtime. Thus, engaging in prolonged screen time before bed stands out as detrimental to sleep improvement efforts.
