If you nap for 20 to 30 minutes, you’ll wake up somewhat refreshed from your time in light sleep, but you won’t have slept long enough to enter deep sleep. Your other option is to take a power nap. Then, you’re much more likely to wake up during light sleep, which is the easiest stage of sleep to wake up from. If you can, sleep for 90 minutes instead. Which is better: sleeping for an hour or not at all?īecause of how sleep cycles work, it’s not a great idea to sleep for only 1 hour. If you’ve ever woken up extremely groggy, it’s likely your alarm went off while you were in deep sleep. Your brain waves are at their slowest during deep sleep. Deep sleep, as you might guess from the name, is the restorative stage of sleep during which you’re deeply asleep. Worse, you’ll probably wake up during deep sleep. If you only sleep for an hour, you’ll cut that cycle short.
Your first sleep cycle takes about 90 minutes. All in, we complete 4 to 5 sleep cycles a night. As the night goes on, the REM portion of each sleep cycle increases. In the first half of the night, you spend more time in light and deep sleep. Your sleep cycle refers to your progression through those different stages of sleep, and it changes throughout the night. When you sleep, you cycle through different stages of sleep, from light sleep to deep sleep to REM and back again. It can all be explained by your sleep cycle. If you’re forced to choose between staying up all night or sleeping for an hour, the better option is to have just a 20 to 30 minute nap instead. The funny thing is: it’s a trick question. Is it better for you to sleep for an hour, or not at all? Whatever your reason, you now find yourself faced with the potential of an all-nighter. You were up late cramming for an exam, preparing for an important work presentation, or simply too busy having fun with friends. We all need at least 7 hours of sleep to be at our best.
