Ukwelashwa ngokukhanya okubomvu kanye nokushiswa kwesikhumba nge-UV kunikeza izinzuzo nezingozi ezahlukene esikhumbeni sakho. Ukwelashwa ngokukhanya okubomvu kusebenzisa ubude bamaza obungewona ama-UV ukukhulisa ukuphulukiswa nokuthuthukisa impilo yesikhumba, kuyilapho ukushiswa kwesikhumba nge-UV kunikeza umbala okhanyayo kodwa kungaholela ekulimaleni kwesikhumba kanye nengozi eyengeziwe yomdlavuza. Ukuze uqonde ukuthi lezi zindlela zokwelapha zihluke kanjani kanye nomthelela wazo esikhumbeni, sicela uqhubeke ufunda. Sicela uqhubeke ufunda ukuze uhlole imininingwane.

Incazelo
Kuyini Ukwelashwa Kokukhanya Okubomvu?
Ukwelashwa ngokukhanya okubomvu kusebenzisa ububanzi obuthile bamaza okukhanya angewona ama-UV, ngokuvamile aphakathi kuka-600 no-900 nm, ukuze kungene esikhumbeni futhi kushukumise izinqubo zemvelo zokuphulukiswa komzimba.
Ukukhanya okubomvu kusiza ukwandisa ukugeleza kwegazi, ukukhiqizwa kwe-collagen, kanye nokushintsha kwamaseli, okuholela ekuthuthukisweni kokuthungwa kwesikhumba, ithoni, kanye nempilo iyonke.
Ukwelashwa ngokukhanya okubomvu kubhekwa njengokwelashwa okuphephile nokungahlaseli okungalimazi isikhumba. Kuvame ukusetshenziselwa ukunciphisa ukubonakala kwemigqa emincane, imibimbi, izibazi, kanye nezinduna, kanye nokukhuthaza ukuphulukiswa kwamanxeba nokunciphisa ubuhlungu.
Kuyini ukushiswa kwe-UV?
Ukushiswa kwe-UV kuhilela ukuchayeka emisebeni ye-ultraviolet (UV), okuyingxenye yokukhanya okungabonakali.
Kunezinhlobo ezimbili eziyinhloko zemisebe ye-UV esetshenziswa ekushiseni ilanga: i-UVA kanye ne-UVB.
I-UVA ingena ngokujulile esikhumbeni futhi ngokuyinhloko ibangela ukushiswa kwesikhumba, kuyilapho i-UVB ibangela kakhulu ukusha futhi ihilelekile ekukhiqizweni kwe-vitamin D. Imisebe ye-UV, ikakhulukazi i-UVB, iyimbangela eyinhloko yokuguga kwesikhumba kanye nokukhula komdlavuza wesikhumba. Kuye kwabonakala ukuthi i-UVB ingabangela ukulimala kwe-DNA, okuholela ekugugeni kwesikhumba kanye nengozi eyengeziwe yomdlavuza wesikhumba.
Ukwelashwa Kokukhanya Okubomvu: Kusetshenziselwa izinjongo ezahlukahlukene, okuhlanganisa ukuvuselela isikhumba, ukuphulukiswa kwamanxeba, ukunciphisa ukuvuvukala, kanye nokwelapha izimo ezithile zesikhumba njenge-acne kanye ne-psoriasis. Kusetshenziselwa futhi ukuqeda ubuhlungu kanye nokululama kwemisipha.
Ukushiswa kwe-UV: Inzuzo eyinhloko yokushiswa kwe-UV umphumela wobuhle we-tan, okuyinto abantu abaningi abayithola ijabulisa ngobuhle. Ukushiswa kwe-UV kuholela nasekukhiqizweni kwevithamini D, ebalulekile empilweni yamathambo kanye neminye imisebenzi yomzimba. Kodwa-ke, izingozi ezingaba khona ezihlobene nokushiswa kwe-UV zivame ukwedlula lezi zinzuzo.
Izingozi
Ukwelashwa Kokukhanya Okubomvu: Uma kusetshenziswa kahle, ukwelashwa kokukhanya okubomvu ngokuvamile kubhekwa njengokuphephile, yize kungabangela imiphumela emibi emincane njengokubomvu noma ukufudumala esikhumbeni. Abukho ubufakazi obusikisela ukuthi kubangela ukulimala kwesikhumba noma umdlavuza.
Ukushiswa kwe-UV: Ingozi ebaluleke kakhulu yokushiswa kwe-UV ukulimala kwesikhumba, okuholela ekugugeni ngaphambi kwesikhathi (imibimbi, isikhumba esifana nesikhumba) kanye nengozi eyengeziwe yomdlavuza wesikhumba, okuhlanganisa ne-melanoma. Ukuchayeka emehlweni emisebeni ye-UV nakho kungabangela umonakalo ku-cornea futhi kufake isandla ekuthuthukisweni kwe-cataracts.
Ekuphetheni, yize ukwelashwa ngokukhanya okubomvu kanye nokushiswa kwe-UV kunganikeza izinzuzo zobuhle kanye nokwelapha, kwenza lokho ngezindlela ezahlukene futhi kuhilela izingozi ezahlukene. Ukwelashwa ngokukhanya okubomvu ngokuvamile kubhekwa njengokuphephile futhi kusetshenziselwa uhla olubanzi lwezinhlelo zokwelapha ngaphandle kwezingozi ezihlobene nokuchayeka ku-UV. Ngakolunye uhlangothi, ukushiswa kwe-UV kunikeza umbala okhanyayo kodwa ngezindleko zomonakalo wesikhumba ongase ube khona isikhathi eside kanye nengozi yomdlavuza eyandisiwe. Abantu kufanele bacabangele ngokucophelela lezi zici lapho bekhetha phakathi kwalezi ezimbili.
