Sleep is big business. People need it. They want it. They’ll spend money to get it. And, according to the bulk of presentations at the 25th annual joint meeting of the American Academy of Sleep Medicine and the Sleep Research Society in Minneapolis (SLEEP 2011) recently, the demand for it continues to far outpace the supply. Given these conditions, it’s not surprising that Americans spend nearly $24 billion on sleep-related goods and services annually, and the market for insomnia drugs is predicted to grow by nearly 80%, to approximately $3.9 billion, in 2012, according to market research conducted by Marketdata Enterprises.
