BOSTON — Here on the bustling exhibit floor at the big annual conference for sleep scientists, it’s easy to see that the business of sleep is booming.
More than 140 companies and other exhibitors have set up shop to hawk everything from pillows and massage chairs to face masks and electrode-studded caps. The big industry players Merck and Philips are here, but so too are the little guys, all the way down to an entrepreneur pitching an indigenous Australian wind instrument known as a didgeridoo as a solution for sleep apnea.
