If you avoid taking naps when you’re tired and instead go for a Red Bull or a 5-Hour Energy because naps make you groggy, it’s because you’re napping too long. The Asap SCIENCE video below explains that the sleep cycle is made up of four stages, the last one of which is REM sleep, in which we dream. The last two stages are also a deep sleep, during which your motor functions shut down, making you feel groggy when you wake up. So as long as you avoid going into the 3rd stage of sleep — which begins about 30 minutes after the first stage — then you’ll get some of the benefits of sleep and wake up feeling refreshed.
If you have an iPhone, there’s a free app called Nap that’s great for quickly setting up power naps. It’s made by Wake N Shake, which may just be the best alarm clock app yet.
