A shortage of sleep is defined when sleep duration is shorter than 7 hours per workday. Short sleep duration is common among young people, despite the negative consequences with up to 73 percent of high school students sleeping less than 8 hours on an average school night. A recent survey from Statista also found that while 40 percent of males stated they do not have sleeping problems, such as trouble sleeping through the night or trouble falling asleep, only 27 percent of females stated they do not have such problems. The most commonly reported negative impacts of missing sleep included looking tired, being less productive, and feeling moody or irritable.
Sleeping aids are a common solution to sleeping problems for many people in the U.S. The most popular over-the-counter (OTC) sleep remedies based on revenue include ZzzQuil liquids, Natrol tablets, Nature's Bounty tablets, and ZzzQuil tablets. The OTC sleep aid market has grown significantly in the past few years due to the high prevalence of sleep disorders, reporting revenue of about 416 million U.S. dollars in 2017, almost double the revenue reported in 2011.
