Answer: by taking 'air naps'

Air Naps -- which are taken in silky, cocoon-shaped hammocks suspended from the ceiling -- were developed for members of the corporate world by Shama Patel at her studio, Flex + Fit, in Charlotte, N.C.

"I created the class to offer overworked corporate America a way to recharge and return to work rejuvenated and ready to take on the day," Patel wrote in her Flex + Fit newsletter.
