Which of the following is NOT a recommended sleep practice?

• A. Keep a consistent sleep schedule
• B. Consume caffeine late in the day
• C. Create a wind-down routine
• D. Limit caffeine late in the day

Answer: (B)

Sleep is supported by habits that regulate your body's clock and lower arousal before bed. Keeping a consistent sleep schedule helps your internal clock stay in sync, making it easier to fall asleep and wake up around the same time each day. A wind-down routine signals to your brain that bedtime is approaching, reducing mental and physical readiness for activity and easing the transition to sleep. Limiting caffeine late in the day is also beneficial because caffeine is a stimulant that can linger in your system for hours, blocking sleep-promoting signals and delaying sleep onset, which can reduce total sleep time and fragment sleep. The option that involves consuming caffeine late in the day is not a recommended sleep practice because it disrupts the very processes these other habits support.
