Kungani abantu bedinga ukulala?

        Lesi isihloko esidala nesisha esingenayo impendulo egculisayo okwamanje. Ezinsukwini zakuqala, kwakubhekwa njengohlobo lokuphumula ekuqapheleni, futhi kamuva kwakubhekwa njengokuphumula kwengqondo kwesikhashana, okufana nokulala kwezilwane, okuwuhlobo oluthile lokuphumula kwengqondo. "ukunqanyulwa nokungasebenzi" amangqamuzana ezinzwa. Kusukela ubuchwepheshe electrophysiological, abantu It kancane kancane wembula yayo "umgubuzelo wemfihlakalo"

　　 Kuvela ukuthi ukulala komuntu akuyona inqubo engenzi lutho futhi emile njengoba kwakucatshangwa ekuqaleni, kubangelwa kuphela ukungena okuqhubekayo kwezisusa ezihlukahlukene ebuchosheni ngesikhathi sokukhathala noma ukuvuka. I-Polysomnography ithole ukuthi ukulala kwabantu kuyinqubo esebenza ngezikhathi ezithile futhi esebenza njalo ezigabeni ezihlukene.

        Ngokwezici ze-electroencephalogram echaziwe, ukunyakaza kwamehlo kanye ne-electromyography, ingahlukaniswa cishe ngokulala kwamehlo okusheshayo (okufushanisiwe ngokuthi i-REM) kanye nokulala kwamehlo okungasheshi (okufushaniswe ngokuthi i-NREM).

        Esigabeni sokulala se-REM, ukunyakaza kwamehlo okusheshayo nokungajwayelekile kungatholakala, ukuphefumula nokushaya kwenhliziyo kukhuphuke, umfutho wegazi uyakhuphuka, futhi ithoni yemisipha iyancipha; ukulala okungasheshi kokunyakaza kwamehlo kungabuye kuhlukaniswe ku-1, 2, 3 4. Phakathi nezikhathi ezine, imisebenzi kagesi yobuchopho evamile neyisici efana ne-spindle yokulala kanye nemisebenzi kagesi yobuchopho ene-amplitude ephezulu ingabonakala phakathi naleso sikhathi. Ukulala kwe-REM kanye nokulala okungeyona i-REM kwakha umjikelezo wokulala, cishe imizuzu engama-60-90, cishe imijikelezo enjalo engu-4-7 ngobusuku obubodwa, abantu abasha balala ubusuku bonke, ukulala kwe-REM kubalelwa ku-20% -25%, kanti -ukulala kokunyakaza kwamehlo okusheshayo kubalelwa ku-75% -80%.

        Ucwaningo olwengeziwe luye lwathola ukuthi esigabeni sokulala se-REM, ukulala okuqhubekayo kuveza ukuphaphama okufushane ngezikhathi ezithile, okuzuzisa umzimba ukuba uhlale uqaphile izinguquko endaweni ezungezile, nokwandisa ukwakheka kwamaprotheni ezinsaneni nasezinganeni ezincane, futhi kunenzuzo gcina umsebenzi wezinzwa kubantu abadala. Qedela, iqhaza ekuguquleni nasekuhlanganiseni inkumbulo. Esigabeni sokulala se-non-REM, kutholakala ukuthi ukusetshenziswa kwamandla emzimbeni kuncishisiwe, futhi ukukhiqizwa kwamahomoni ahlukahlukene e-pituitary kuyanda, futhi ukukhiqizwa kwe-hormone yokukhula kufinyelela inani eliphakeme esigabeni sesine, ngakho-ke kungaqeda. umzimba' ukukhathala nokubuyisela amandla omzimba.

Ngamafuphi, ukulala kubaluleke kakhulu empilweni engokwenyama nangokwengqondo yomzimba womuntu. Abantu kufanele bahlele ukuphila kwabo ngokwesayensi, babe nezimiso ezivamile, balale kahle, futhi bajabulele ukuphila okujabulisayo.
