Which description captures a sleep hygiene benefit?

Which description captures a sleep hygiene benefit?

• A. Practices that promote good sleep (regular schedule, limiting screens) that improve mood and functioning
• B. Maintaining irregular sleep
• C. Using screens during bedtime
• D. Sleeping in the daytime

Answer: (A)

Sleep hygiene involves routines and environmental factors that support good sleep quality and daytime functioning. The description that mentions a regular sleep-wake schedule and limiting screen use captures this, because a consistent schedule helps align our internal clock with the 24-hour day, making it easier to fall asleep and stay asleep, which in turn improves mood and cognitive functioning during the day. Limiting screens reduces blue light and arousal that can delay sleep, further supporting restful sleep. The other options describe behaviors that hinder sleep: irregular sleep disrupts circadian rhythm and reduces sleep quality; using screens at night increases wakefulness and delays sleep; sleeping in the daytime misaligns with the natural day-night cycle.
