NASA likes a 26 minute nap

 Nice News -  Using data from long-haul space crews, NASA researchers found that those who napped for around 26 minutes showed improved alertness and performance compared to those who didn’t. That may sound quite short, but there’s science backing up the so-called “NASA nap.” Cassie Hilditch, with NASA’s Fatigue Countermeasures Laboratory, explained to Good Housekeeping that with a brief afternoon snooze, “you are less likely to go into the deeper stages of sleep, what we call slow-wave sleep, and you are more likely to stay in the lighter stages.” That means waking up refreshed, rather than groggy.
