Nap strategically to avoid disrupting nighttime sleep

Limit daytime naps to 20-30 minutes and finish them before 3 PM. A short "power nap" restores alertness without entering deep sleep stages that cause grogginess or interfere with your ability to fall asleep at night.

Why It Works

Sleep pressure (adenosine buildup) accumulates throughout the day and drives your urge to sleep at night. A long or late nap discharges too much of that pressure, leaving you wide awake at bedtime. Keeping naps short and early preserves enough sleep drive for a solid night.

Tips

• Set an alarm so you do not accidentally oversleep past 30 minutes
• If you consistently need long naps, it may signal insufficient nighttime sleep — address the root cause first
• A brief walk or splash of cold water on the face can substitute for a nap when you need a midday energy boost without risking nighttime disruption
