Editing Jet lag (section)

According to a 1969 study by the [[Federal Aviation Administration]], aviator [[Wiley Post]] was the first to write about the effects of flying across time zones in his 1931 co-authored book, ''Around the World in Eight Days''.<ref>{{cite book |author-last1=Post |author-first1=Wiley |author-last2=Gatty |author-first2=Harold |date=1931 |title=Around the World in Eight Days |location=London |publisher=Hamilton}}</ref><ref>{{cite report |url=https://www.faa.gov/data_research/research/med_humanfacs/oamtechreports/1960s/media/AM69-17.pdf#page=5 |title=Time-Zone Effects On the Long Distance Air Traveler |last1=Siegel |first1=P.

Instead, these effects were attributed to ''[[travel fatigue]] factors'' such as anxiety about air travel, disruption to routine, and dehydration from the dryness of the prolonged aircraft time. <ref>{{cite journal |last1=Waterhouse |first1=Jim |last2=Reilly |first2=T |last3=Edwards |first3=Ben J |title=The stress of travel |journal=Journal of Sports Sciences |date=November 2004 |volume=22 |issue=10 |pages=946-65; discussion 965-6 |doi=10.1080/02640410400000264 |pmid=15768727 |url=https://www.researchgate.net/publication/7965590}}</ref> Jet lag started associating with circadian rhythms in the 1970s with the rise of [[Entrainment (chronobiology)|entrainment]] and phase shift research, mimicking similar symptoms to jet lag when rhythms were disrupted.<ref>{{cite journal |last1=Aschoff |first1=J |title=Human circadian rhythms in activity, body temperature and other functions |journal=Life Sciences and Space Research |date=1967 |volume=5 |pages=159–173 |pmid=11973844 |url=https://pubmed.ncbi.nlm.nih.gov/11973844/}}</ref> These associations began the official recognition of jet lag as an effect of circadian disruption rather than a factor of travel fatigue.

The term jet lag is inspired by how people feel after travelling rapidly over several time zones, typically on a plane or jet-like form of transportation. The body’s feeling of having to adjust to the new time zone serves as the inspiration for the “lag” component of the term.<ref>{{cite journal |last1=Arendt |first1=Josephine |title=Approaches to the Pharmacological Management of Jet Lag |journal=Drugs |date=2018 |volume=78,14 (2018) |issue=14 |pages=1419–1431 |doi=10.1007/s40265-018-0973-8 |pmid=30167980 |pmc=6182450 }}</ref> The term’s first use was found in a ''Los Angeles Times'' article on February 13, 1966. Horace Sutton wrote, “If you’re going to be a member of the Jet Set and fly off to [[Kathmandu|Katmandu]] for coffee with [[Mahendra of Nepal|King Mahedra]], you can count on contracting Jet lag, a debility not unakin to a hungover. Jet Lag derives from the simple fact that jets travel so fast they leave your rhythms behind.” The term began gaining popularity soon after, continuing to increase to this day. <ref>{{cite web |url=https://books.google.com/ngrams/graph?content=jetlag&year_start=1800&year_end=2022&corpus=en&smoothing=3}}</ref>
