Mayelana nalolu hlelo lokusebenza

Umuntu unenkolelo ethile yokushintshashintsha kokusebenza nokungasebenzi phakathi nosuku, futhi ngokwalolu daba, abantu abaningi bangabangelwa omunye "wama-chronotypes" amaningi. Abaphenyi bahlukanisa okuyisisekelo okubili, ngomqondo othile ama-chronotypes ahlukile: i-chronotype yasekuseni - "ama-lark" ne-chronotype yakusihlwa - "izikhova". Abanye abacwaningi bahlukanisa ukulandelana kwezikhathi eziphakathi nendawo: ukuhleleka, ukuhlangana - "amajuba" kanye "ne-bimodal". Izici eziyinhloko zama-chronotypes zimi kanje:
AmaLark: vuka ngokuzimela futhi kalula ekuseni, bayasebenza engxenyeni yokuqala yosuku, banciphe ntambama; lala kusenesikhathi.
"Izikhova": zivuka ngokwazo sekwephuzile, kungakadluli amahora ama-2-3 ngaphambi kwemini, ukuphakama komsebenzi kusihlwa nasebusuku; hamba uyolala sekuhlwile, imvamisa phakathi kwamabili.
"Amajuba": ukuvuka wedwa ekuseni, ngemuva kwesikhashana kune- "larks", umsebenzi phakathi nosuku uhlala njalo, ngaphandle kweziqongo ezibonakalayo nemikhombe; hamba uyolala ihora nesigamu ngaphambi kwamabili.
"I-Bimodal": abamele le chronotype babonakala ngokuvela ngasikhathi sinye kwezimpawu zezinhlobo zasekuseni ezedlulele nezinkulu kakhulu kusihlwa ngaphandle kokubusa kwanoma iyiphi yazo.
Phakathi kwabantu basemadolobheni enkabeni yeRussia, cishe u-40-45% kukhona "izikhova", cishe ama-25% "ama-lark", ama-30-35% asele yi "arrhythmics" kanye "bimodals". Ukuba wohlobo oluthile lwezikhathi kuxhomeke ekuxhumaneni kwendawo, isimo sezulu, isikhathi sezithombe zemvelo kanye "nokungcola okuncane" emadolobheni.
