Which practice helps improve sleep quality?

• A. Eat a heavy meal right before bed
• B. Exercise vigorously at night
• C. Limit caffeine late in the day
• D. Create a wind-down routine

Answer: (D)

Improving sleep quality comes from signals we give our body that it’s time to wind down. Creating a wind-down routine does exactly that by establishing a predictable transition from wakefulness to sleep. When you engage in calm, low-energy activities in a dim environment—like quiet time, light stretching, gentle breathing, and turning off screens—you reduce mental chatter and physical tension. This lowers arousal levels, helps you fall asleep faster, and improves the consistency and depth of your sleep, which is the essence of better sleep quality. It also supports aligning your schedule with your natural rhythms, making sleep more restorative over time.

The other options tend to disrupt this transition: a heavy meal before bed can cause discomfort and digestion issues that interrupt sleep; vigorous exercise at night raises heart rate and body temperature, delaying sleep onset; and while limiting caffeine late in the day is helpful, it doesn’t provide the same reliable cue for sleep as a steady routine that your body learns to expect each night.
