Answer: Nap
Clues: “Short” and “Sleep”
80% of people take naps, even if it’s just a brief one before bed.
There’s new research out that says the “perfect” nap-time is 1:42 P.M. and that the optimum nap length is 51 minutes, meaning you’d wake up at 2:33 P.M.
If a nap goes longer than that, at around an hour-and-a-half, it can do more harm than good for your momentum and energy levels. And if it goes on for two-and-a-half hours, then it’s officially a full sleep session.
But for some people, even 51 minutes can be too long.
One sleep expert advised that naps should be kept short with “20 to 30 minutes” being ideal.
The people at NASA agree, a while back, they did a study and found the perfect length for a nap is 26 minutes, because you’re only going through the first two stages of sleep in that time. (Others also recommend this length.)
