Ukuphefumula (ukuphefumula kwangaphandle) kuyinkqubo enikezwa uhlelo lokuphefumula futhi limele ukushintshaniswa kwegesi phakathi komzimba kanye nemvelo. Lapho ukuphefumula, i-oksijeni ingena emzimbeni, okudingekayo ekusebenzeni kwezinsimbi eziphilayo, lapho kubalwa khona amandla amakhulu. Futhi i-carbon dioxide eyenziwa kulezi zinqubo isuswa. Kwenzekani emzimbeni ngokubambezeleka kokuphefumula nokuthi ngabe kuyingozi - kulokhu sizama ukuyihlola.
I-Physiology yokubopha ukuphefumula
Ukuphefumula kungenye yamakhono ambalwa omzimba olawulwa ngokucophelela noma engazi lutho. Okusho ukuthi, umsebenzi we-reflex, kodwa ungaqondwa ngokucophelela.
Ngokuphefumula okuvamile, isikhungo sokuphefumula sithumela impucuko kumisipha yesifuba nesigxathu, okwenza ukuba bavumelane. Ngenxa yalokho, umoya ungena emaphashini.
Lapho ukuphefumula kubambezeleka, i-carbon dioxide, engakwazi ukuphuma emaphashini, iqoqa egazini. U-oksijeni uqala ukugxila kakhulu ngama-tishu, i-hypoxia eqhubekayo iqala (okuqukethwe okuphansi kwe-oksijini egazini). Umuntu ovamile uyakwazi ukugcina umoya wakhe ngamasekhondi angu-30 kuya kwangu-70, bese ubuchopho buphefumula. Futhi, uma ngesizathu esithile i-oksijeni inikezekile (isibonelo, ezintabeni), ngaleyo ndlela ngokusebenzisa ama-receptors akhethekile asabela ekunciphiseni oksijini kanye nokwanda kwe-carbon dioxide egazini, ubuchopho buthola isignali futhi kwandisa amandla okuphefumula. Okufanayo kwenzeka nangomsebenzi wokusebenza osebenzayo. Yile ndlela indlela engaqondakali ngayo, ukulawulwa okuzenzakalelayo kokuphefumula kwenzeka.
Uma ukhuluma, udla, ukukhwehlela, ukuphefumula ukuphefumula kwenzeka njalo ngeziphefumulelwe noma ngokuphefumula - i-apnea. Ukuboshwa okungapheli okuphefumula kwemigqa engaphezu kwengu-10 kungenzeka njalo kwabanye abantu ebusuku (ukulala kwe-apnea syndrome).
Ngenkathi uqhuba ukuzivocavoca okukhethekile nokuzilibazisa ngokuphefumula (isibonelo, ku-yoga noma ngesikhathi sokukhishwa), ungafunda ukubamba umoya wakho isikhathi eside kakhulu. Izidakamizwa zibamba umoya wazo cishe amaminithi angu-3-4, kanye nabaphathi be-yoga - imizuzu engu-30 noma ngaphezulu.
Ukulimala kokuphuza umoya ekuphusheni
Njengoba kuphawuliwe ngenhla, ukuphefumula ebusuku lapho ubuthongo kungukuzimela kokulala okungavamile. Ubude besikhathi esijwayelekile buyizinqamuzana ezingu-20-30, kodwa ngezinye izikhathi kufinyelela emaminithini angu-2-3. Isibonakaliso salesi sifo sishaya. Umuntu ophethwe yi-apnea yokulala ebusuku ubese ephefumula ephusheni, bese evuka ukuze angene. Ngakho-ke ingahlala izikhathi ezingu-300 kuya ku-400 ebusuku. Umphumela walokhu ukulala okuphansi, okuholela emakhanda, ukucasula, ukunciphisa inkumbulo nokunakwa, neminye imiphumela emibi.
Izimbangela ze-apnea yasebusuku:
- Isikhungo sokuphefumula se-cerebral saphela ukunikeza izibonakaliso emisipha yokuphefumula isikhathi esithile;
- ukugeleza komoya akukwazi ukufika emaphashini ngenxa yokwehliswa kwe-lumen ye-airways (i-larynx, amavesi angasese);
- ezinye izifo ezesabekayo nezesabekayo.
Ukubamba umoya wakho ephusheni kungaba yingozi, ngakho-ke ukwelashwa kubaluleke kakhulu.
Ukulibaziseka kokuphefumula kokubuyisela
Ngokusho kocwaningo lwesayensi, ukulibazisa ukuphefumula kokuzizwa kuyasiza kakhulu emzimbeni. Ubufakazi balokhu yizimpumelelo zama-yoga amakhosi.
Izindlela zokuphefumula zinomthelela oqondile
Kubalulekile ukwenza kahle amasu okuphefumula okuphefumula okwenzayo okuphephile nokuphumelelayo. Ukuze uqiniseke ngokubulawa okulungile futhi uzuze imiphumela emihle, usizo lomfundisi ofanelekayo kuyadingeka.
