A short nap during the day can feel like a mini-vacation for your brain. In many cultures, a siesta is a respected tradition. But is napping always beneficial, or can it disrupt your nighttime sleep? The key lies in understanding the science of napping.
The Power Nap: Short and Sweet
Research suggests that short naps (10-30 minutes) can significantly improve alertness, performance, and mood without causing "sleep inertia" (that groggy feeling after waking from a deep sleep). This is because you primarily stay in the lighter stages of non-REM sleep.
