Ukuphupha ukulala, okuvame ukubizwa ngokuthi i-REM noma ukunyakaza kokunyakaza kwe-eye ngokushesha, kungenye yezinto ezimbili eziyisisekelo zokulala. Esinye isimo esiyisisekelo sokulala silele ukulala kwe-NREM noma ukungahambi kahle kwe-eye ukulala.
Ukulala okuphusayo kuyaphawuleka ngokuba khona kokunyakaza kwamehlo okusheshayo (REM). Amaphupho angenzeka ngesikhathi sokulala kwe-REM, yingakho futhi eyaziwa ngokuthi iphupho lokulala.
Amaphupho awavamile okwenzeka kwezinye izifunda zokulala.
Ukuphupha Ukulala
Ukulala okuphusayo kuyisimo esijulile sokulala nokusebenza okukhulu kobuchopho ku-forebrain ne-midbrain. Kuboniswa ikhono lamaphupho okwenzekayo, kanye nokungabikho kwezimoto ngaphandle kwemisipha yamehlo kanye ne-diaphragm. Amaphupho okulala ahamba ngokuphindaphindiwe izikhathi eziningana ngesikhathi sokulala, kodwa ihlanganisa ingxenye encane kunazo zonke zomjikelezo wokulala .
Ngesikhathi sokulala kwe-REM, kunezinguquko ekucindezelweni kwegazi , izinga lokushaya kwenhliziyo, nokukala kokuphefumula jikelele. Futhi ngesikhathi sokulala kwe-REM, ukugeleza kwegazi kuya kwanda ebuchosheni, kanye ne-penis kanye ne-clitoris, eholela engxenyeni. Ukulala kwe-REM yisimo esijulile sokulala, kodwa asibheki ingxenye enkulu kunazo zonke zomjikelezo wokulala.
Ukungenzi Ukuphuza Ukulala
Ukuphupha ukulala, noma i-REM ingenye yezinto ezimbili eziyisisekelo zokulala. Esinye isimo esiyisisekelo sokulala akusiyo ngokushesha ukuhamba kwamehlo okulala noma ukulala kwe-NREM.
I-NREM iphinde ibhekiswe njengokulala okungenalo okuphuphayo, njengoba amaphupho akwenzeki phakathi nalesi simo sokulala. Ngokungafani nokulala kwe-REM okuyisiteleka esisodwa, esijulile sokulala, i-NREM inezinyathelo ezintathu ezihlukene.
Izigaba ezintathu ezihlukene zokulala kwe-NREM yi-N1, N2, ne-N3, futhi umbuso ngamunye ngokwahlukene unamaphethini omgogodla kagesi ohlukile, ohlukile, futhi owaziwayo.
Ukunyakaza okungekho okusheshayo ukulala kwesibindi ngokuvamile kubonakala ngokunciphisa ukugeleza kwegazi kuya ebuchosheni kanye nasiswini samathambo.
Imijikelezo Yokulala
I-REM ne-NREM yokulala enye emjikelezweni kulo lonke ubusuku. Ngokuvamile, kunemijikelezo emine eya kweyisithupha yokulala kwe-NREM ubusuku bonke. Le mijikelezo ye-NREM yokulala iyingxenye enkulu kunazo zonke zokulala ubusuku bonke. Ukujikeleza kokulala kwe-NREM kulandelwa izikhathi zokulala kwe-REM, okuyinto ubuthongo obunzima kakhulu. Ngokuvamile, imijikelezo yokulala idlule cishe imizuzu engu-90.
Njengoba ubusuku obuvamile buqhubeka, izikhathi zokulala ze-NREM zifinyeleleka ubude, kanti izinkathi zokulala kwe-REM ziba isikhathi eside. Ngamanye amazwi, kuthatha isikhashana ukulala okungathí sina ukuthatha isikhathi kusihlwa. Ngenxa yalesi sizathu, ukubuthwa kwe-REM akuvumi ukufezwa ngesikhathi se-naps emfushane. Ngokwesilinganiso, umuntu omdala uchitha cishe u-25% wobusuku ebuthongweni be-REM. Iphesenti yesikhathi esichitha kubuthongo be-REM ingase ihle ngo-age.
Futhi eyaziwa ngokuthi: Ukuphupha ukulala nakho kuvame ukubizwa ngokuthi ukulala kwe-REM noma ubuthongo obunzima. Ukulala kwe-NREM kuyaziwa ngokuthi ubuthongo obungenalo ukuphupha, njengoba amaphupho akwenzeka ngesikhathi sokulala kwe-REM.
Izibonelo: Ukuphuza ukulala, owaziwa nangokuthi ubuthongo be-REM, kwenzeka ngokuhamba ngebhayisikili ebusuku kodwa akwenzi ingxenye enkulu kunazo zonke zomjikelezo wokulala.
