The folks at NASA have come up with some very important research about sleep. NASA conducted a study to determine how long our NAPS should be.
They determined that the perfect length for a nap is 26 minutes.
NASA said that when you nap for just 26 minutes, you could be 54% more alert and even 34% better at whatever you after you wake up.
Here's why. At 26 minutes, you're only going through the first two stages of sleep . . . you're not entering the others, which can make you feel groggy or even feel WORSE when you wake up.
