Employers prowling for workplace nappers
But is the gain short-lived? A quick cat nap, in the vicinity of 15 to 20 minutes (no more than 25), will maximize productivity and mental acuity, says Betsy Connolly of Circadian Technologies. Naps longer than 20-25 minutes cause a person to go into such a deep sleep that he or she will be groggy when awakening. Despite the perception by management that those who nap on the job are slackers, perhaps nappers are actually the most productive, she says.
