Umjikelezo wokulala: yiziphi izigaba nokuthi zisebenza kanjani

-Delile

• Umjikelezo wokulala uhlala isikhathi esingakanani
• Izigaba ezi-4 zokulala
• 1. Ukulala kancane (Isigaba 1)
• 2. Ukulala kancane (Isigaba 2)
• 3.Ukulala ubuthongo obukhulu (Isigaba 3)
• 4.Ukulala kwe-REM (Isigaba 4)

Umjikelezo wokulala uyisethi yezigaba eziqala kusukela lapho umuntu elala futhi aqhubeke futhi ajule ajule, aze umzimba ungene ebuthongweni be-REM.

Imvamisa, ukulala kwe-REM kunzima kakhulu ukukufeza, kepha kulesigaba lapho umzimba ungakhululeka khona futhi lapho izinga lokuvuselelwa kobuchopho liphezulu kakhulu. Iningi labantu lilandela iphethini elandelayo yezigaba zokulala:

1. Ukulala okuncane kwesigaba 1;
2. Ukulala okuncane kwesigaba 2;
3. Isigaba 3 ukulala okujulile;
4. Ukulala okuncane kwesigaba 2;
5. Ukulala okuncane kwesigaba 1;
6. REM ukulala.

Ngemuva kokuba sesigabeni se-REM, umzimba ubuyela esigabeni 1 futhi bese uphinda zonke izigaba uze ubuyele esigabeni se-REM futhi. Lo mjikelezo uyaphindwa ubusuku bonke, kepha isikhathi sokulala kwe-REM siyanda ngomjikelezo ngamunye.

Yazi ukuphazamiseka okuyinhloko okungu-8 okungathinta umjikelezo wokulala.

Umjikelezo wokulala uhlala isikhathi esingakanani

Umzimba uhamba imijikelezo eminingana yokulala ngobusuku obubodwa, owokuqala uhlala cishe imizuzu engama-90 bese isikhathi sikhuphuka, size sifinyelele esilinganisweni semizuzu eyi-100 ngomjikelezo ngamunye.

Umuntu omdala uvamise ukuba nemijikelezo yokulala ephakathi kuka-4 no-5 ubusuku ngabunye, ogcina ngokuthola amahora ayisishiyagalombili okulala adingekayo.

Izigaba ezi-4 zokulala

Ukulala kungahlukaniswa izigaba ezi-4, ezihlukanisiwe:

1. Ukulala kancane (Isigaba 1)

Lesi isigaba sokulala esilula kakhulu esihlala cishe imizuzu eyi-10. Isigaba 1 sokulala siqala lapho uvala amehlo akho futhi umzimba uqala ukulala, noma kunjalo, kusenokwenzeka ukuthi uvuke kalula nganoma yimuphi umsindo owenzeka egumbini, ngokwesibonelo.

Ezinye izici zalesi sigaba zifaka:

• Ungazi ukuthi usuvele ulele;
• Ukuphefumula kuhamba kancane;
• Kungenzeka ube nomuzwa wokuthi uyawa.

Ngalesi sigaba, imisipha ayikakhululeki, ngakho-ke umuntu usahambahamba embhedeni futhi angavula ngisho amehlo akhe ngenkathi ezama ukulala.

2. Ukulala kancane (Isigaba 2)

Isigaba 2 yisigaba cishe wonke umuntu asibhekisa kuye lapho ethi bangabalali abancane. Kuyisigaba lapho umzimba usuvele ukhululekile futhi ulele, kepha ingqondo iyalalela futhi, ngenxa yalesi sizathu, umuntu usengavuka kalula nomuntu ohamba ngaphakathi ekamelweni noma onomsindo endlini.

Lesi sigaba sihlala cishe imizuzu engama-20 futhi, kubantu abaningi, yisigaba umzimba ochitha isikhathi esiningi kuyo yonke imijikelezo yokulala.

3.Ukulala ubuthongo obukhulu (Isigaba 3)

Lesi yisigaba sokulala okujulile lapho imisipha ikhululeka ngokuphelele, umzimba awuzweli kakhulu ezintweni ezingaphandle, njengokuhamba noma umsindo. Kulesi sigaba ingqondo inqanyuliwe, ngakho-ke, awekho amaphupho. Kodwa-ke, lesi sigaba sibaluleke kakhulu ekulungiseni umzimba, njengoba umzimba uzama ukwelulama ekulimaleni okuncane obekuvela emini.

4.Ukulala kwe-REM (Isigaba 4)

Ukulala kwe-REM yisigaba sokugcina somjikelezo wokulala, esihlala cishe imizuzu eyi-10 futhi imvamisa siqala imizuzu engama-90 ngemuva kokulala. Kulesi sigaba, amehlo ahamba ngokushesha okukhulu, izinga lokushaya kwenhliziyo liyakhuphuka futhi kuvela amaphupho.

Kukulesi sikhathi lapho kungavela khona inkinga yokulala eyaziwa ngokuthi yi-sleepwalking, lapho umuntu angavuka khona azungeze indlu, angalokothi avuke. Isigaba se-REM sithatha isikhathi eside ngomjikelezo ngamunye wokulala, sifinyelela kumizuzu engama-20 noma engama-30 ubude.

Funda kabanzi ngokuhamba ngokulala nezinye izinto ezi-5 ezingajwayelekile ezingenzeka ngesikhathi sokulala.
