Sleep is an essential component to maintaining health. In children, sleep is also vital for growth and development. Ongoing [[sleep deprivation]] has been linked to an increased risk for some chronic health problems. In addition, sleep deprivation has been shown to correlate with both increased susceptibility to illness and slower recovery times from illness.<ref>{{cite journal |last=Pilkington |first=Stephanie |date=7 August 2013 |title=Causes and consequences of sleep deprivation in hospitalized patients |journal=Nursing Standard |volume=27 |issue=49 |pages=35–42 |doi=10.7748/ns2013.08.27.49.35.e7649|pmid=23924135 }}</ref> In one study, people with chronic insufficient sleep, set as six hours of sleep a night or less, were found to be four times more likely to catch a cold compared to those who reported sleeping for seven hours or more a night.<ref>{{cite web|url=http://www.cmu.edu/news/stories/archives/2015/august/sleep-and-sickness.html |title=New Research Confirms Lack of Sleep Connected to Getting Sick |publisher=cmu.edu |author=Shilo Rea |date=31 August 2015|access-date=25 November 2015}}</ref> Due to the role of sleep in regulating [[Sleep and metabolism|metabolism]], insufficient sleep may also play a role in [[weight gain]] or, conversely, in impeding [[weight loss]].<ref>{{cite journal |last1=Patel |first1=Sanjay R. |last2=Hu |first2=Frank B. |date=17 January 2008 |title=Short sleep duration and weight gain: a systematic review |journal=Obesity (Silver Spring) |volume=16 |issue=3 |pages=643–53 |doi=10.1038/oby.2007.118 |pmid=18239586 |pmc=2723045}}</ref> Additionally, in 2007, the [[International Agency for Research on Cancer]], which is the cancer research agency for the [[World Health Organization]], declared that "shiftwork that involves [[Circadian rhythm|circadian]] disruption is probably [[carcinogen]]ic to humans", speaking to the dangers of long-term nighttime work due to its intrusion on sleep.<ref>{{cite web |url=http://www.iarc.fr/en/media-centre/pr/2007/pr180.html |title=IARC Monographs Programme finds cancer hazards associated with shiftwork, painting and firefighting |publisher=International Agency for Research on Cancer |date=5 December 2007 |access-date=25 November 2015 |archive-url=https://web.archive.org/web/20110721001355/http://www.iarc.fr/en/media-centre/pr/2007/pr180.html |archive-date=21 July 2011 |url-status=dead }}</ref> In 2015, the National Sleep Foundation released updated recommendations for sleep duration requirements based on age, and concluded that "Individuals who habitually sleep outside the normal range may be exhibiting signs or symptoms of serious health problems or, if done volitionally, may be compromising their health and well-being."<ref>{{cite journal |author1=Hirshkowitz, Max |author2=Whiton, Kaitlyn | title=National Sleep Foundation's sleep time duration recommendations: methodology and results summary | journal= Sleep Health |url= http://www.sleephealthjournal.org/article/S2352-7218(15)00015-7/fulltext |date=14 January 2015 | pmid = 29073412| doi= 10.1016/j.sleh.2014.12.010 |access-date=25 November 2015 |display-authors=etal | volume=1 |issue=1 | pages=40–43|s2cid=205190733 }}</ref>
