Ukwelashwa ngokukhanya okubomvu kanye nokushiswa kwesikhumba nge-UV kunikeza izinzuzo nezingozi ezahlukene esikhumbeni sakho. Ukwelashwa ngokukhanya okubomvu kusebenzisa amaza angewona ama-UV ukukhulisa ukuphulukiswa nokuthuthukisa impilo yesikhumba, kuyilapho ukushiswa kwesikhumba nge-UV kunikeza ukushiswa kwesikhumba kodwa kungaholela ekulimaleni kwesikhumba kanye nengozi yomdlavuza eyandayo. Ufuna ukuqonda ukuthi lezi zindlela zokwelapha zihluke kanjani kanye nomthelela wazo esikhumbeni sakho? Qhubeka ufunda ukuze uhlole imininingwane!
Incazelo
Kuyini ukwelashwa ngokukhanya 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, futhi 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-UVAingena ngokujulile esikhumbeni futhi ngokuyinhloko inesibopho sokushintsha umbala wesikhumba, kuyilaphoI-UVBinesibopho esikhulu sokushisa futhi ibandakanyeka ekukhiqizweni kwe-vitamin D. Imisebe ye-UV, ikakhulukazi i-UVB. Ingabangela umonakalo we-DNA, okuholela ekugugeni kwesikhumba kanye nengozi eyengeziwe yomdlavuza wesikhumba.
Izinzuzo
Ukwelashwa Kokukhanya Okubomvu:Isetshenziselwa izinjongo ezahlukahlukene, okuhlanganisa ukuvuselela isikhumba, ukuphulukiswa kwamanxeba, ukunciphisa ukuvuvukala, kanye nokwelapha izimo ezithile zesikhumba njenge-acne kanye ne-psoriasis. Iphinde isetshenziswe ekunciphiseni ubuhlungu kanye nokululama kwemisipha.
Ukushiswa kwe-UV:Inzuzo eyinhloko yokushiswa yi-UV umphumela wobuhle we-tan, okuyinto abantu abaningi abayithola ijabulisa ngobuhle. Ukushiswa yi-UV kuholela nasekukhiqizweni kwevithamini D, ebalulekile empilweni yamathambo kanye neminye imisebenzi yomzimba. Kodwa-ke, izingozi ezihlobene nokushiswa yi-UV zivame ukwedlula lezi zinzuzo.
Izingozi
Ukwelashwa Kokukhanya Okubomvu:Ngokuvamile kubhekwa njengokuphephile uma kusetshenziswa kahle, ukwelashwa kokukhanya okubomvu kungabangela imiphumela emibi emincane njengokubomvu noma ukufudumala esikhumbeni. Akukho bufakazi obusikisela ukuthi kubangela ukulimala kwesikhumba noma umdlavuza.
Ukushiswa kwe-UV:Ingozi ebaluleke kakhulu yokushiswa yi-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.
Isiphetho
Nakuba kokubili ukwelashwa kokukhanya okubomvu kanye nokushiswa kwe-UV kungaba nezinzuzo zobuhle kanye nokwelapha, kusebenza ngezindlela ezahlukene futhi kunezingozi ezahlukene. Ukwelashwa kokukhanya 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. Ngakho-ke, abantu kufanele bacabangele ngokucophelela lezi zici lapho bekhetha phakathi kwalezi ezimbili.
