Ngokwesayensi, ukulala kuyisimo esishintshile somsebenzi wobuchopho esihluke kakhulu ekubeni uphapheme. Ngesikhathi sokulala, amangqamuzana obuchopho asebenza kancane kodwa ngamandla. Lokhu kungabonakala ku-electroencephalogram: umsebenzi we-bioelectrical wehla ngobuningi, kodwa ukhuphuka ku-voltage. Cabangela izigaba ezine zokulala nezici zazo. Ukuphefumula nokushaya kwenhliziyo kujwayelekile, imisipha ikhululekile, izinga lokushisa lomzimba liyancipha. Asizazi kangako izisusa zangaphandle, futhi ukwazi kancane kancane kuyaphuma eqinisweni. Umsindo omncane wanele ukuphazamisa lesi sigaba sokulala (ngaphandle kokuqaphela ukuthi ubulele nhlobo). Cishe u-10% wokulala ebusuku uyadlula kulesi sigaba. Abanye abantu bavame ukudikiza ngalesi sikhathi sokulala (isibonelo, iminwe noma izitho). Isigaba 1 ngokuvamile sithatha imizuzu eyi-13-17. Lesi sigaba sibonakala ngokuphumula okujulile kwemisipha nokulala. Ukubona ngokomzimba kunciphisa kakhulu, amehlo awanyakazi. Umsebenzi we-bioelectrical ebuchosheni wenziwa ngefrikhwensi ephansi uma uqhathaniswa nokuvuka. Isigaba sesibili sithatha cishe ingxenye yesikhathi esichithwa ubuthongo. Isigaba sokuqala nesesibili zaziwa njengezigaba zokulala ezilula futhi ndawonye zihlala cishe imizuzu engama-20-30. Ngesikhathi sokulala, sibuyela esigabeni sesibili izikhathi eziningana. Sifinyelela esigabeni esijulile sokulala cishe ngemizuzu engu-30, isigaba 3, futhi ngemizuzu engu-45, isigaba sokugcina sesi-4. Umzimba wethu ukhululeke ngokuphelele. Sinqanyuliwe ngokuphelele kulokho okwenzekayo eduze neqiniso. Kudingeka umsindo omkhulu noma ukuthuthumela ukuze uphaphame kulezi zigaba. Ukuvusa umuntu osesigabeni sesi-4 cishe akunakwenzeka - kufana nokuzama ukuvusa isilwane esilalayo. Lezi zigaba ezimbili zenza u-20% wokulala kwethu, kodwa isabelo sazo siyehla ngokuya ngeminyaka. Isigaba ngasinye sokulala sifeza injongo ethile ngomzimba. Umsebenzi oyinhloko wazo zonke izigaba umphumela wokuvuselela ezinkambisweni ezihlukahlukene emzimbeni.
