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 23 percent of Gen Zers and 21 percent of Millennials reporting they get just 6 hours of sleep each night. Moreover, around 44 percent of U.S. adults reported feeling sleepy for 2 to 4 days out of the week as of 2019. Common negative impacts due to not getting enough sleep include irritablity, headache, and a general feeling of unwell.

Sleeping aids are a common solution to sleeping problems for many people in the U.S. The leading sleeping aid tablet brands in the United States based on sales in 2019 include Natrol, Nature's Bounty, and Nature Made. 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 402 million U.S. dollars in 2019, compared to 217 million U.S. dollars in 2011.
