The consulting firm expects the market to grow by an average of 6.3% a year through 2022. That's largely because the world's population is aging, and older people are more susceptible to sleep disorders. In addition to silk eye masks and mattresses that cost more than a luxury car, dozens of high-tech products are available to aid the sleepless masses. They include glasses that seek to reset your circadian rhythms by shining a green light into your eyes ($299), and a smartphone charging station shaped like a bed ($100) to encourage you to tuck in your devices when you retire for the night. SHUTi is an option for people who are interested in cognitive behavioral therapy for insomnia (see Smart Strategies to Get More Sleep) but who don't have the time to see a trained therapist or can't find one nearby. Users take a 40-minute online course once a week for six weeks, and they're offered strategies and tools to practice between sessions. The cost is $135.

Insight Timer, a free smartphone app, offers thousands of stress-reducing meditations, including some specifically designed to lull you to sleep. Another option is the "Sleep With Me" podcast, in which host and creator Drew Ackerman tells boring bedtime stories designed to make you nod off. Whether it works is debatable, but the podcast is free and there are no known side effects.
