Ososayensi bathole ukuthi inyanga ithinta umjikelezo wokulala. Ngokushesha ngaphambi kwenyanga egcwele, abantu balala ngaphambi kokujwayelekile futhi balale isikhathi esifushane. Ucwaningo lwazibandakanyeka ososayensi abavela eWashington, Yale Amanyuvesi kanye neNational University of Kilmes (Argentina). Bashicilela imiphumela yocwaningo ngoJanuwari 27 kwi-Science Advances Magazine.
Ngokusho kweqembu lokucwaninga, izigaba zokuthula ziguqukela kulo lonke umjikelezo wenyanga, othatha izinsuku ezingama-29,5. Ochwepheshe babuke abantu abahlala ezimweni ezihluke ngokuphelele: amadolobhana namadolobha, ngokufinyelela kugesi futhi ngaphandle kwawo. Ababambiqhaza ekuhlolweni bekungezigaba zeminyaka ehlukene futhi bengenazo amaqembu. Ngokuvamile, inyanga yaba nethonya elikhulu kulabo ababehlala ezindaweni zasemakhaya.
Ababambiqhaza bokuhlolwa bafakwa kwiziqali ezikhethekile eziqaqayo ezilandelela izindlela zokulala. Ngasikhathi sinye, iqembu elilodwa lenqabile ugesi kuyo yonke le nkathi yocwaningo, okwesibili - yayivimbela ukufinyelela kuye, nolwesithathu - ugesi osetshenzisiwe ngaphandle kwemikhawulo.
Ukuncika kukagesi kusekhona, ngoba ababambiqhaza beqembu lesithathu balala ngemuva kokuphumula futhi balala kancane. Kungenzeka ukwenqabe umphumela wenyanga, kepha kwahlolwa okufanayo nabafundi base-University of Washington, okuthola ukufinyelela ngogesi okugcwele.
Imiphumela yocwaningo inikeza isizathu sokukholelwa ukuthi izigqi zabantu eseceleni ngendlela ethile zivumelaniswa nezigaba zomjikelezo wenyanga. Kuwo wonke amaqembu, kwalandelwa iphethini ejwayelekile: Abantu balala kamuva balala ngezikhathi ezithile zesikhathi izinsuku ezingama-3-5 ngaphambi kwenyanga egcwele.
Ngokusho kweLeanDro Casiragi, umcwaningi wase-University of Washington, ukuncika kokulala kwabantu kusuka ezigabeni ze-luna kuyinto yazimisele. Kusukela ezikhathini zasendulo, umzimba womuntu ufunde ukusebenzisa imithombo yemvelo yokukhanya. Ngaphambi kwenyanga egcwele, i-satellite yezwe ifinyelela osayizi abakhulu futhi, ngokufanele, inani lokukhanya liyanda - ubusuku buba lula.
Izigqi zakwa-CircAsian zidlala indima enkulu empilweni yomuntu. Bamele ama-oscillations ezinqubo ezahlukahlukene zebhayoloji emzimbeni futhi ahlotshaniswa ngqo kusuka ekushintsheni kwemini nobusuku. Isikhathi se-lyrthms aseduze cishe amahora angama-24. Yize ukuxhumana kwazo nemvelo yangaphandle kukhanyeka kakhulu, nalezi zingoma zinemvelaphi ephelele - okungukuthi, kudalwe ngokuqondile ngumzimba.
Amawashi e-biological anezimpawu ezithile kanye nokwehluka komuntu ngamunye kumuntu ngamunye. Ngokusekelwe kule datha, ososayensi babela ama-Chronoomy amathathu. "Ukuqhafaza" ukuma amahora ambalwa ngaphambili kune- "Owls" futhi kubonise umsebenzi ophakeme kakhulu ekuseni. "Owl" - kunalokho, ekwazi ukukwazi ukubopha ntambama. Futhi i-chrootype ephakathi nendawo icatshangelwa "amajuba".
