Ukungazali kanye nokungazali kuyanda, kokubili kwabesifazane nabesilisa, emhlabeni wonke.
Ukungabi nanzalo kusho ukungakwazi, njengombhangqwana, ukukhulelwa ngemva kwezinyanga eziyi-6 kuya kweziyi-12 zokuzama. Ukungazali kubhekisela ekubeni nethuba elinciphile lokukhulelwa, uma kuqhathaniswa neminye imibhangqwana.
Kulinganiselwa ukuthi u-12-15% wemibhangqwana ufuna, kodwa awukwazi, ukukhulelwa. Ngenxa yalokhu, ukwelashwa kokuzala njenge-IVF, i-IUI, izindlela zamahomoni noma zemithi, izinqubo zokuhlinzwa, nokuningi, kuyanda ngokushesha ekuthandweni.
Ukwelashwa okulula (ngezinye izikhathi okwaziwa ngokuthii-photobiomodulation, i-LLLT, ukwelashwa kokukhanya okubomvu, i-laser ebandayo, njll.) ikhombisa isithembiso sokuthuthukisa impilo yezingxenye eziningi zomzimba ezahlukene, futhi ihlolwe kokubili ukuzala kwabesifazane kanye nokuzala kwabesilisa. Ingabe ukwelashwa kokukhanya kuyindlela yokwelapha ukuzala efanele? Kulesi sihloko sizoxoxa ngokuthi kungani ukukhanya kungaba yikho konke okudingayo...
Isingeniso
Ukungazali kuyinkinga yomhlaba wonke kwabesilisa nabesifazane, kanti amazinga okuzala ehla ngokushesha, kwamanye amazwe angaphezu kwamanye. 10% wabo bonke abantwana abazalwa njengamanje eDenmark bakhulelwa ngosizo lwe-IVF kanye nobuchwepheshe obufanayo bokuzala. 1 kwabangu-6 abashadile eJapane abanazo inzalo, kanti uhulumeni waseJapan usanda kungenelela ukukhokhela izindleko ze-IVF zabashadile ukuze kumiswe inkinga yabantu eqhubekayo. Uhulumeni waseHungary, ofisa ukwandisa amazinga okuzalwa aphansi, wenze ukuthi abesifazane abanezingane ezine noma ngaphezulu bakhululwe impilo yabo yonke ekukhokheni intela yengeniso. Ukuzalwa kowesifazane ngamunye kwamanye amazwe aseYurophu kungaphansi kuka-1.2, futhi kuphansi kuka-0.8 eSingapore.
Amanani okuzalwa abelokhu ehla emhlabeni wonke, okungenani kusukela ngawo-1950 nakwezinye izifunda ngaphambi kwalokho. Akukhona nje ukungabi nabantwana kwabantu okukhulayo, izinhlobo ezahlukene zezilwane nazo zinezinkinga, njengezilwane zasemapulazini nezasekhaya. Ingxenye yalokhu kwehla kwamanani okuzalwa ibangelwa izici zezenhlalo nezomnotho - imibhangqwana ikhetha ukuzama ukuthola abantwana kamuva, lapho ukuzala kwemvelo sekuvele kwehlile. Enye ingxenye yokwehla yizici zemvelo, zokudla kanye nama-hormone. Isibonelo, inani lesidoda kwabesilisa elijwayelekile lehle ngo-50% eminyakeni engama-40 edlule. Ngakho-ke amadoda namuhla akhiqiza ingxenye kuphela yamaseli esidoda amaningi njengoba oyise nomkhulu babo benza ebusheni babo. Izinkinga zokuzala zabesifazane njenge-polycystic ovarian syndrome (PCOS) manje zithinta abesifazane abangafika ku-10%. I-Endometriosis (isimo lapho izicubu zesibeletho zikhula kwezinye izindawo zesistimu yokuzala) nayo ithinta owesifazane oyedwa kwabayi-10, ngakho-ke cishe abesifazane abayizigidi ezingama-200 emhlabeni jikelele.
Ukwelashwa okulula kuyindlela entsha yokwelapha ukungabi nabantwana, futhi nakuba iwela ngaphansi kwesigaba esifanayo 'se-ART' (ubuchwepheshe bokuzala obusizwayo) njenge-IVF, iyindlela yokwelapha eshibhile kakhulu, engangenisi, futhi elula ukuyifinyelela. Ukwelashwa okulula kusungulwe kahle kakhulu ekwelapheni izinkinga zempilo yamehlo, izinkinga zobuhlungu, ukuphulukiswa, njll., futhi kufundwa ngamandla emhlabeni wonke ngezimo eziningi nezingxenye zomzimba. Iningi lokwelashwa kokukhanya kwamanje kocwaningo lokuzala livela emazweni amabili - iJapan neDenmark - ikakhulukazi ocwaningweni lokuzala kwabesifazane.
Ukuzala Kwabesifazane
Ama-50%, cishe ingxenye, yawo wonke imibhangqwana engenanzalo abangelwa yizici zabesifazane kuphela, kanti amanye ama-20% ayinhlanganisela yokungabi nabantwana kwabesifazane nabesilisa. Ngakho-ke cishe ama-7 kwangu-10Inkinga yokukhulelwa ingathuthukiswa ngokubhekana nempilo yokuzala yabesifazane.
Izinkinga ze-thyroid kanye ne-PCOS ziphakathi kwezimbangela eziphambili zokungazali, zombili azihlolwanga kahle (Funda kabanzi ngempilo ye-thyroid kanye nokwelashwa kokukhanya lapha). I-Endometriosis, i-fibroids kanye nokunye ukukhula kwangaphakathi okungafuneki kubanga elinye iphesenti elikhulu lamacala okungazali. Uma owesifazane engazali, cishe u-30% wesikhathi kuzoba nezinga elithile le-endometriosis. Ezinye izimbangela ezivamile zokungazali yilezi; ukuvaleka kwamapayipi e-fallopian, izibazi zangaphakathi ngenxa yokuhlinzwa (kufaka phakathi ukuhlinzwa kwe-C), kanye nezinye izinkinga zokukhishwa kwamaqanda ngaphandle kwe-pcos (ukuvuvukala, ukungajwayelekile, njll.). Ezimweni eziningi imbangela yokungazali ayichazwa nje - akwaziwa ukuthi kungani. Kwezinye izimo ukukhulelwa nokufakelwa kwamaqanda kwenzeka, kodwa kamuva ekukhulelweni kokuqala kuba nokukhishwa kwesisu.
Njengoba izinkinga zokuzala zikhula ngokushesha, kube nokwanda okulinganayo kwezokwelapha nocwaningo lokungazali. IJapane njengezwe inenye yezinkinga zokuzala ezimbi kakhulu emhlabeni, enezinga eliphezulu kakhulu lokusetshenziswa kwe-IVF. Futhi bangamaphayona ekufundeni imiphumela yokwelashwa kokukhanya ekuthuthukiseni ukuzala kwabesifazane….
Ukwelashwa okulula kanye nokuzala kwabesifazane
Ukwelashwa ngokukhanya kusebenzisa ukukhanya okubomvu, ukukhanya okuseduze kwe-infrared, noma inhlanganisela yakho kokubili. Uhlobo olufanele lokukhanya ngenhloso ethile luyahlukahluka kuye ngengxenye yomzimba.
Uma ubheka ukuzala kwabesifazane ngqo, izinhloso eziyinhloko yi-uterus, ama-ovari, ama-fallopian tubes kanye nezinhlelo zama-hormone ezijwayelekile (i-thyroid, ubuchopho, njll.). Zonke lezi zicubu zingaphakathi komzimba (ngokungafani nezingxenye zokuzala zabesilisa), ngakho-ke uhlobo lokukhanya olungena kahle luyadingeka, njengoba iphesenti elincane kuphela lokukhanya okushaya isikhumba elizongena phansi ezicutshini ezifana nama-ovari. Ngisho noma ubude besikhathi bunikeza ukungena okuhle, inani elingena lisencane kakhulu, ngakho-ke kudingeka nokukhanya okukhulu kakhulu.
Ukukhanya okuseduze kwe-infrared kuma-wavelength aphakathi kuka-720nm no-840nm kungene kahle kakhulu ezicutshini zezinto eziphilayo.. Lolu hlu lokukhanya lwaziwa ngokuthi 'Ifasitela Eliseduze Ne-Infrared (esicutshini sezinto eziphilayo)' ngenxa yezakhiwo ezihlukile zokudlula zijule emzimbeni. Abacwaningi ababheka ukuthuthukisa ukungazali kwabesifazane ngokukhanya bakhethe kakhulu ubude be-wavelength obuseduze ne-infrared obungu-830nm ukuze bacwaningwe. Lo bude be-wavelength obungu-830nm abugcini nje ngokungena kahle, kodwa futhi bunemiphumela enamandla emaseli ethu, buthuthukisa ukusebenza kwawo.
Ukukhanya entanyeni
Olunye ucwaningo lwakuqala oluvela eJapane lwalusekelwe ku-'The Proximal Priority Theory'. Umqondo oyisisekelo uwukuthi ubuchopho buyisitho esiyinhloko somzimba futhi zonke ezinye izitho nezinhlelo zamahomoni zisuka ebuchosheni. Kungakhathaliseki ukuthi lo mbono ulungile noma cha, kukhona iqiniso kuwo. Abacwaningi basebenzise ukukhanya kwe-infrared okungu-830nm eduze kwentamo yabesifazane baseJapan abangenayo inzalo, benethemba lokuthi imiphumela eqondile nengaqondile (ngegazi) ebuchosheni ekugcineni izoholela ezimweni ezingcono zamahomoni kanye ne-metabolic emzimbeni wonke, ikakhulukazi ohlelweni lokuzala. Imiphumela yayimihle kakhulu, ngephesenti eliphezulu labesifazane ababebhekwa 'njengabanganayo inzalo kakhulu' hhayi nje ngokukhulelwa, kodwa futhi nokuthola ukuzalwa okuphilayo - ukwamukela izingane zabo emhlabeni.
Ngemva kokufunda ngokusebenzisa ukukhanya entanyeni, abacwaningi babenesifiso sokuthi ukwelashwa kokukhanya kungathuthukisa yini amazinga empumelelo yokukhulelwa kwemvelo kanye ne-IVF.
Ukukhulelwa kwe-in vitro kwaziwa njengendlela yokugcina lapho izindlela zendabuko zokukhulelwa zehlulekile. Izindleko ngomjikelezo ngamunye zingaba phezulu kakhulu, ngisho nangaphezu kwalokho ezingakwazi ukwenzeka emibhangqwaneni eminingi, kanti abanye bathatha imali mboleko njengendlela yokugembula ukuze bayixhase. Amazinga empumelelo ye-IVF angaba phansi kakhulu, ikakhulukazi kwabesifazane abaneminyaka engu-35 noma ngaphezulu. Njengoba kunezindleko eziphakeme kanye nezinga eliphansi lempumelelo, ukuthuthukisa amathuba omjikelezo we-IVF kubalulekile ukuze kufezwe umgomo wokukhulelwa. Ukuqeda isidingo se-IVF nokukhulelwa ngokwemvelo ngemva komjikelezo ohlulekile kukhanga nakakhulu.
Amazinga okufakelwa kweqanda elivundisiwe (okubalulekile kokubili ku-IVF kanye nokukhulelwa okuvamile) kucatshangwa ukuthi ahlobene nokusebenza kwe-mitochondrial. I-mitochondria esebenza kancane iyaphazamisa ukusebenza kweseli leqanda. I-mitochondria etholakala kumaseli eqanda izuzwe njengomama, futhi ingaba nokuguqulwa kwe-DNA kwabesifazane abathile, ikakhulukazi njengoba iminyaka ikhula. Ukwelashwa kokukhanya okubomvu nokuseduze kwe-infrared kusebenza ngqo ku-mitochondria, kuthuthukisa ukusebenza futhi kunciphisa izinkinga ezifana nokuguqulwa kwe-DNA. Lokhu kuchaza ukuthi kungani ucwaningo oluvela eDenmark lubonise ukuthi izingxenye ezimbili kwezintathu zabesifazane ababehlulekile imijikelezo ye-IVF ngaphambili bathola ukukhulelwa okuphumelelayo (ngisho nokukhulelwa kwemvelo) ngokwelashwa kokukhanya. Kwakukhona ngisho necala lowesifazane oneminyaka engu-50 ubudala ekhulelwa.
Ukukhanya esiswini
Inqubo esetshenziswe kulolu cwaningo evela eDenmark yayihilela izikhathi zokwelapha ngokukhanya kwe-infrared cishe ngesonto, lapho ukukhanya kufakwa ngqo esiswini, ngomthamo omkhulu impela. Uma owesifazane engakhulelwanga ngesikhathi somjikelezo wokuya esikhathini wamanje, ukwelashwa kwaqhubeka kuze kube okulandelayo. Esampulweni yabesifazane abangu-400 ababengenanzalo ngaphambili, abangu-260 babo bakwazi ukukhulelwa ngemva kokwelashwa ngokukhanya kwe-infrared. Kubonakala sengathi ukwehla kwekhwalithi yamaqanda akuyona inqubo engenakuguqulwa. Lolu cwaningo luphakamisa imibuzo mayelana nenqubo ye-ART yokususa i-nucleus yeqanda lowesifazane bese ifakwa emangqamuzaneni amaqanda omnikeli (owaziwa ngokuthi ukudluliselwa kwe-mitochondrial, noma umuntu/izingane zabazali) - ingabe kuyadingeka ngempela lapho amaqanda owesifazane engase abuyiselwe ngokwelashwa okungangenisi ukutheleleka.
Ukusebenzisa ukwelashwa okulula ngqo esiswini (ukuze kuqondiswe kuma-ovari, esibelethweni, emashubhu e-fallopian, emaseli amaqanda, njll.) kucatshangwa ukuthi kusebenza ngezindlela ezimbili. Okokuqala kuthuthukisa indawo yokuzala, ukuqinisekisa ukuthi amaseli amaqanda ayakhishwa ngesikhathi sokuvuthwa, angahamba emashubhu e-fallopian, futhi angafakwa odongeni lwesibeletho olunempilo olunokugeleza kwegazi okuhle, i-placenta enempilo ingakheka, njll. Enye indlela ihilela ukuthuthukisa impilo yeseli leqanda ngqo. Amaseli e-oocyte, noma amaseli amaqanda, adinga amandla amaningi uma kuqhathaniswa namanye amaseli ezinqubo ezihlobene nokuhlukaniswa kwamaseli nokukhula kwawo. La mandla anikezwa yi-mitochondria - ingxenye yeseli ethintwa ukwelashwa kokukhanya. Ukwehla komsebenzi we-mitochondria kungabonakala njengembangela eyinhloko yokungabi nabantwana kweseli. Lokhu kungaba yincazelo eyinhloko yamacala amaningi okuzala 'okungachazwanga' nokuthi kungani ukuzala kwehla ngokukhula - amaseli amaqanda awakwazi ukwenza amandla anele. Ubufakazi bokuthi adinga futhi asebenzisa amandla amaningi kangaka butholakala iqiniso lokuthi kune-mitochondria ephindwe izikhathi ezingu-200 kumaseli amaqanda uma kuqhathaniswa namanye amaseli avamile. Lokho kuphindwe izikhathi ezingu-200 amathuba emiphumela nezinzuzo ezivela ekwelashweni kokukhanya uma kuqhathaniswa namanye amaseli emzimbeni. Kuwo wonke amaseli emzimbeni womuntu wonke, owesilisa noma owesifazane, iqanda lingaba uhlobo oluthola ukuthuthukiswa okukhulu kakhulu okuvela ekwelashweni kokukhanya okubomvu nokuseduze kwe-infrared. Inkinga kuphela ukuthola ukukhanya kungene ezinqeni zamaqanda (okwengeziwe ngalokho ngezansi).
Zombili lezi zindlela zokwelapha ngokukhanya noma imiphumela 'ye-photobiomodulation' ndawonye zakha indawo enempilo nentsha, efanele ukusekela umbungu okhulayo.
Ukuzala Kwabesilisa
Abesilisa bayimbangela cishe yama-30% emibhangqwaneni engenanzalo, kanye nenhlanganisela yezici zabesilisa nabesifazane ezibalelwa ku-20% ngaphezulu kwalokho. Ngakho-ke ingxenye yesikhathi, ukuthuthukisa impilo yokuzala yabesilisa kuzoxazulula izinkinga zokuzala zombhangqwana. Izinkinga zokuzala kwabesilisa zivame ukuhambisana nokusebenza okuphansi kwamasende, okuholela enkingeni ngesidoda. Kunezinye izimbangela ezahlukahlukene futhi, njenge-retrograde ejaculate, i-dry ejaculate, ama-antibodies ahlasela isidoda, kanye nezici eziningi zofuzo nezemvelo. Umdlavuza kanye nokutheleleka kungalimaza unomphela ikhono lamasende lokukhiqiza isidoda.
Izinto ezifana nokubhema ugwayi kanye nokuphuza utshwala njalo zinomthelela omubi kakhulu ekubalweni kwesidoda kanye nekhwalithi yesidoda. Ukubhema kukababa kunciphisa ngisho nezinga lempumelelo yemijikelezo ye-IVF ngesigamu.
Kodwa-ke, kunezici zemvelo nezokudla ezingathuthukisa ukukhiqizwa kwesidoda kanye nekhwalithi, njengokuthuthukiswa kwesimo se-zinc kanye nokwelashwa ngokukhanya okubomvu.
Ukwelashwa okulula akwaziwa kakhulu ngokwelapha izinkinga zokuzala, kodwa ukusesha okusheshayo ku-pubmed kwembula izifundo eziningi.
Ukwelashwa Okukhanyayo kanye nokuzala kwabesilisa
Ukwelashwa ngokukhanya (okwaziwa nangokuthi i-photobiomodulation) kuhilela ukusetshenziswa kokukhanya okubomvu okubonakalayo, noma okungabonakali eduze kwe-infrared, emzimbeni futhi kufundwe kahle kakhulu ngempilo yesidoda.
Ngakho-ke yiluphi uhlobo lokukhanya olungcono kakhulu futhi yiluphi ubude be-wavelength obuqondile? Obomvu, noma eduze kwe-infrared?
Ukukhanya okubomvu ku-670nm okwamanje kuyindlela ecwaningwe kahle kakhulu futhi ephumelelayo yokuthuthukisa impilo yokuzala yabesilisa kanye nekhwalithi yesidoda.
Amaseli esidoda asheshayo futhi aqinile
Ucwaningo lubonisa ukuthi ngisho nangemva kweseshini eyodwa nje yokwelashwa ngokukhanya okubomvu, ukunyakaza kwesidoda (isivinini sokubhukuda) kuthuthuka kakhulu:
Ukunyakaza noma ijubane lamaseli esidoda kubaluleke kakhulu ekuzaleni, njengoba ngaphandle kwejubane elanele, isidoda asisoze sathatha uhambo lokufinyelela iqanda lesifazane futhi silivundise. Ngobufakazi obuqinile nobucacile bokuthi ukwelashwa kokukhanya kuthuthukisa ukunyakaza, ukusebenzisa idivayisi yokwelapha yokukhanya efanele kubonakala kubalulekile kunoma yimuphi umbhangqwana ongenanzalo. Ukunyakaza okuthuthukisiwe okuvela ekwelashweni kokukhanya kunganqoba ngisho nenkinga yokubala kwesidoda okuphansi, ngoba ukuhlushwa okuphansi kwesidoda kusazokwazi ukufinyelela futhi (omunye wabo) kuvundise iqanda.
Izigidi zamaseli esidoda
Ukwelashwa okulula akugcini nje ngokuthuthukisa ukuhamba, izifundo ezahlukahlukene zibonisa ukuthi kungathuthukisa kanjani ukubalwa/ukuhlushwa kwesidoda, kungagcini nje ngokunikeza isidoda esisheshayo, kodwa futhi kunikeze okuningi.
Cishe wonke amaseli emzimbeni wethu ane-mitochondria - okuhloswe ngayo ukwelashwa kokukhanya okubomvu - kufaka phakathi amaSertoli Cells. Lawa amaseli akhiqiza isidoda sama-testes - indawo lapho kwenziwa khona isidoda. Ukusebenza kahle kwala maseli kubalulekile kuzo zonke izici zokuzala kwabesilisa, kufaka phakathi inani lesidoda.
Izifundo zikhomba ukwelashwa kokukhanya okuthuthukisa inani lamaSeli eSertoli emasendeni wesilisa, ukusebenza kwawo (kanye nenani lamaseli/inani lesidoda alikhiqizayo), kanye nokunciphisa ukukhiqizwa kwamaseli esidoda angajwayelekile. Inani lesidoda selilonke liye labonakala lithuthuka ngokuphindwe kabili kuya kahlanu kwabesilisa abanezibalo eziphansi ngaphambilini. Kokunye ukuhlola okuvela eDenmark, inani lesidoda likhuphuke lisuka ezigidini ezimbili nge-ml laya ngaphezu kwezigidi ezingama-40 nge-ml ngokwelashwa okukodwa kuphela kwamasende.
Inani eliphezulu lesidoda, ukuhamba kwesidoda okusheshayo, kanye nokuntuleka kwesidoda esingajwayelekile ngezinye zezizathu ezibalulekile zokuthi kungani ukwelashwa kokukhanya kuyingxenye ebalulekile yokuthuthukisa noma iyiphi inkinga yokuzala kwabesilisa.
Gwema ukushisa ngazo zonke izindleko
Inothi elibalulekile mayelana nokwelashwa kokukhanya kwama-testes:
Amasende abantu ehla esuka emzimbeni aye esinqeni ngenxa yesizathu esibalulekile – adinga izinga lokushisa eliphansi ukuze asebenze. Lapho izinga lokushisa lomzimba elijwayelekile lingu-37°C (98.6°F) awakwazi ukukhiqiza isidoda. Inqubo ye-spermatogenesis idinga ukwehla kwezinga lokushisa eliphakathi kwama-degrees angu-2 no-5 ukusuka ekushiseni komzimba okuyinhloko. Kubalulekile ukucabangela le mfuneko yokushisa lapho ukhetha idivayisi yokwelapha ukukhanya kokuzala kwabesilisa – uhlobo lokukhanyisa olusebenzisa amandla amaningi kumele lusetshenziswe – ama-LED. Ngisho nama-LED, kunomphumela wokufudumala omncane ozwakalayo ngemva kwezikhathi ezinde. Ukusebenzisa umthamo ofanele nobude obufanele bokukhanya okubomvu okusebenzisa amandla kahle kuyisihluthulelo sokuthuthukisa ukuzala kwabesilisa. Ulwazi olwengeziwe ngezansi.
Indlela esebenza ngayo – lokho okwenziwa ukukhanya okubomvu/kwe-infrared
Ukuze siqonde kahle ukuthi kungani ukukhanya okubomvu/kwe-IR kusiza kokubili ekuzaleni kwabesilisa nabesifazane, sidinga ukwazi ukuthi kusebenza kanjani ezingeni lamaseli.
Indlela yokusebenza
Imiphumela yeukwelashwa kokukhanya okubomvu nokuseduze kwe-infraredkucatshangwa ukuthi kuvela ekusebenzisaneni nama-mitochondria amaseli ethu. Lokhu 'ukuguquguquka kwe-photobio' kwenzeka lapho ubude bamaza obufanele bokukhanya, obuphakathi kuka-600nm no-850nm, bumuncwa yi-mitochondrion, futhi ekugcineni kuholele ekukhiqizweni kwamandla okungcono kanye nokuvuvukala okuncane esitokisini.
Enye yezinhloso ezibalulekile zokwelapha ngokukhanya yi-enzyme ebizwa ngokuthi i-Cytochrome C Oxidase – ingxenye yenqubo yokuthutha kwe-electron chain ye-metabolism yamandla. Kuyaqondakala ukuthi kunezinye izingxenye eziningana ze-mitochondria ezithintekayo. Lezi mitochondria zivame kakhulu kumaseli amaqanda kanye nesidoda.
Ngemva nje kweseshini yokwelashwa ngokukhanya, kungenzeka ukubona ukukhishwa kwe-molecule ebizwa ngokuthi i-Nitric Oxide emaseli. Le molecule ye-NO ivimbela ukuphefumula, ivimbele ukukhiqizwa kwamandla kanye nokusetshenziswa komoya-mpilo. Ngakho-ke, ukuyisusa esitokisini kubuyisela umsebenzi ojwayelekile onempilo. Ukukhanya okubomvu nokuseduze kwe-infrared kucatshangwa ukuthi kuhlukanisa le molecule yokucindezeleka ku-enzyme ye-Cytochrome C Oxidase, kubuyisele izinga elinempilo lokusetshenziswa komoya-mpilo kanye nokukhiqizwa kwamandla.
Ukwelashwa okulula nakho kunomthelela emanzini angaphakathi kwamaseli ethu, kuwenza abe nesikhala esikhulu phakathi kwe-molecule ngayinye. Lokhu kushintsha izakhiwo zamakhemikhali nezomzimba zeseli, okusho ukuthi izakhamzimba nezinsiza kungangena kalula, ubuthi bungakhishwa ngaphandle kokumelana okuncane, ama-enzyme namaprotheni asebenza kahle kakhulu. Lo mphumela emanzini eseli awusebenzi ngqo ngaphakathi kwamaseli, kodwa nangaphandle kwawo, esikhaleni esingaphandle kweseli kanye nezicubu ezifana negazi.
Lokhu kumane nje kuyisifinyezo esifushane sezindlela ezimbili zokusebenza ezingaba khona. Kungenzeka ukuthi kunemiphumela enenzuzo eyengeziwe, engaqondakali ngokugcwele, eyenzeka ezingeni lamaseli ukuchaza imiphumela yokwelashwa kokukhanya.
Zonke izinto eziphilayo zixhumana nokukhanya – izitshalo zidinga ukukhanya ukuze zidle, abantu badinga ukukhanya kwe-ultraviolet ukuze bathole i-vitamin D, futhi njengoba zonke izifundo zibonisa, ukukhanya okubomvu nokuseduze kwe-infrared kubalulekile kubantu nasezilwaneni ezahlukahlukene ukuze kusebenze kahle umzimba ngisho nokuzala.
Imiphumela yokwelashwa ngokukhanya ayibonakali nje kuphela endaweni okuqondiswe kuyo iseshini, kodwa futhi iyabonakala nangokwesimiso. Isibonelo, iseshini yokwelashwa ngokukhanya esandleni sakho inganikeza izinzuzo enhliziyweni. Iseshini yokwelashwa ngokukhanya entanyeni inganikeza izinzuzo ebuchosheni, okungathuthukisa ukukhiqizwa/isimo samahomoni futhi kuholele ekuthuthukisweni okukhulu kwempilo yomzimba wonke. Ukwelashwa ngokukhanya kubalulekile ekususeni ukucindezeleka kwamangqamuzana nokuvumela amaseli akho ukuthi asebenze ngokujwayelekile futhi amaseli ohlelo lokuzala awahlukile.
