An estimated 40 million Americans suffer from chronic sleep disorders, and an additional 20 million have short-term sleeping issues, experts say. The frequency of chronic sleep disorders is higher for the elderly, as about half of all people older than 65 have reported having sleep difficulties. The most common sleep disorders include insomnia, which is when it’s difficult to fall asleep or stay asleep, and sleep apnea, a disorder that is characterized by short stops in breathing during sleep. In the US, sleep disorders and their accompanying sleep deprivation are estimated to lead to about $16 billion US Dollars (USD) in medical expenses every year.
