Which statement best describes a poor sleep hygiene practice?

• A. Maintaining a regular sleep schedule
• B. Limiting caffeine and nicotine
• C. Watching screens in bed to relax
• D. Creating a dark, quiet environment

Answer: (C)

Understanding sleep hygiene means recognizing behaviors that help you fall asleep and stay asleep. Watching screens in bed to relax is a poor sleep hygiene practice because the light from screens, especially blue light, signals your brain that it’s daytime, delaying melatonin release and increasing alertness. This makes it harder to wind down and fall asleep. It also trains your brain to associate the bed with wakefulness and stimulation rather than rest. By contrast, a regular sleep schedule, limiting caffeine and nicotine, and creating a dark, quiet environment support consistent, high-quality sleep. So, watching screens in bed to relax best describes a poor sleep hygiene practice.
