Okuqukethwe
Isigaba somjikelezo wokulala
Njengokulala kancane kancane noma ukulala okujulile, ubuthongo be-REM bunjalo esinye sezigaba zomjikelezo wokulala. Kubantu abadala, kulandela ukulala kancane, futhi kuyisigaba sokugcina somjikelezo wokulala.
Kumuntu omdala onempilo engenankinga yokulala, isikhathi sokulala kwe-REM sithatha cishe 20 kuya ku-25% wesikhathi sobusuku, futhi iyanda ngomjikelezo ngamunye kuze kube yilapho ivuka.
Ukulala kwe-REM, noma ukulala okungaphumuli: incazelo
Sikhuluma ngokulala “okuyindida” ngoba umuntu ulala ajule, kodwa nokho ubonisa lokho okungafaniswa nakho. izimpawu zokuvuka. Ukusebenza kobuchopho kukhulu. Ukuphefumula kuyashesha uma kuqhathaniswa nezigaba zokulala zangaphambilini, futhi ukushaya kwenhliziyo nakho kungase kube okungajwayelekile. Umzimba awusebenzi (sikhuluma nge-muscle atony ngoba imisipha ikhubazekile), kodwa ukunyakaza okujeqeza kungase kwenzeke. Ukuqhanyelwa kungenzeka, kokubili emadodeni (umthondo) nakwabesifazane (clitoris), ezinganeni nakubantu abadala.
Uhlobo lokulala olukhuthaza amaphupho
Qaphela ukuthi uma singaba namaphupho kuzo zonke izigaba zokulala, ukulala kwe-REM ikakhulukazi kusiza amaphupho. Ngesikhathi sokulala kwe-REM, amaphupho avame kakhulu, kodwa futhi ikakhulukazi okukhulu, abaphumuli. Angaba futhi amaphupho esiwakhumbula kakhulu uma sivuka.
Kungani ibizwa nangokuthi i-Sleep Rapid Eye Movement, noma i-REM
Ngaphezu kokuyaluza okusobala komuntu olele, ukulala kwe-REM kubonakala ngokuba khona ukunyakaza kwamehlo okusheshayo. Amehlo anyakaza ngemuva kwezinkophe. Kungakho omakhelwane bethu abangamaNgisi bebiza lesi sigaba sokulala ngokuthi i-REM: “Ukunyakaza kwamehlo okusheshayo”. Ubuso bungabuye buveze ngokucacile umzwelo, kungakhathaliseki ukuthi intukuthelo, injabulo, ukudabuka noma ngisho nokwesaba.
Ukuvela kokulala okuyindida ezinganeni
QEDA ukulala shintsha indawo phakathi nomjikelezo wokulala phakathi kokuzalwa nobungane, futhi ubude bayo buyashintsha. Ngempela, ekuzalweni, ukulala kwengane encane kuhlanganisa izigaba ezimbili kuphela, ngaphezu kokulala: ukulala okungaphumuli, ukulala kwe-REM kwesikhathi esizayo, okuza kuqala futhi kuthinte u-60% womjikelezo, nokulala kancane, noma okuzolile. Umjikelezo ube usuthatha imizuzu engama-40 kuye kwengama-60.
Kusukela cishe ezinyangeni ezi-3, ubuthongo obungaphumuli bushintsha bube ubuthongo obuyindida, kodwa bugcine indawo yabo yokuqala esitimeleni sokulala. Kube sekulandelwa wukulala kancane kancane, bese kuba wubuthongo obujulile. Ngaleso sikhathi kuphakathi nezinyanga ezingu-9 kuphela lapho ukulala kwe-REM kubekwa khona okokugcina emjikelezweni wokulala, ngemva kokulala kancane kancane nokulala kancane okujulile. Ezinyangeni eziyisithupha, ukulala kwe-REM kumelela kuphela u-35% womjikelezo wokulala, futhi ezinyangeni ezingu-9, inyamalala ngokuphelele ebuthongweni basemini (i-naps) futhi ibala kuphela u-20% wokulala ebusuku, njengabantu abadala. .
Futhi, njengabantu abadala, ukulala kwe-REM ezinganeni nasezinganeni kubonakala ngokuthi isimo sokungaphumuli ngenkathi umzimba u-amorphous. Phakathi nalesi sigaba sokulala, umntwana angakwazi ngisho nokuzala imizwa eyisisekelo eyisithupha yokudabuka, injabulo, ukwesaba, intukuthelo, ukumangala noma ukunengeka. Ngisho noma ingane ibonakala inobunzima, kungcono ungamvusi, ngoba eqinisweni ulele ubuthongo.
Ukulala okuyindida: indima okufanele icaciswe
Nakuba sazi izinto eziningi ngokwengeziwe mayelana nokulala nezigaba zakho ezihlukene, ikakhulukazi ngenxa yobuchwepheshe obusha emkhakheni wezithombe zezokwelapha, ukulala okuyindida kuseyindida kakhulu. Iqhaza layo alikacaci. Uma izinqubo zokukhumbula ziwubuthongo obunensa, ukulala kwe-REM nakho kungadlala indima enkumbulweni nasekungeneni ukuvuthwa kobuchopho, ikakhulukazi ngoba iyingxenye ebalulekile yomjikelezo wokulala wosana. Ngokusho kwe-Inserm, ukuhlolwa kwamagundane kubonise ukuthi ukucindezelwa kwalesi sigaba sokulala kubangela ukuphazamiseka ekwakhiweni kobuchopho.
Ngakho-ke ukulala kwe-REM kungase kubaluleke ukuhlanganisa inkumbulo, kodwa futhi nokudala nokuxazulula izinkinga.
