Uma kukhulunywa ngokuthola umbala wesikhumba okhanyayo, abantu abaningi bayazibuza ukuthi ukusebenzisa umbhede wokushiswa kwesikhumba kungcono yini—noma kubi—kunokushisa kwesikhumba ngaphansi kwelanga lemvelo. Nakuba kokubili kuveza isikhumba emisebeni ye-ultraviolet (UV), imibhede yokushiswa kwesikhumba kanye nokukhanya kwelanga kuhluke kakhulu ku-Ukwakheka kwe-UV, ukuqina, ukulawula, kanye nezingozi zempilo.
Ukuqonda lo mehluko kungakusiza ukuthi wenze izinqumo ezinolwazi mayelana nokushiswa kwesikhumba kanye nokuvikelwa kwesikhumba.
Imisebe ye-UV: Imibhede Yokushiswa Kwelanga vs Ilanga
Ukukhanya Kwelanga Kwemvelo
Ilanga likhipha ububanzi obuhlukahlukene bemisebe ye-UV:
-
Imisebe ye-UVAzingena zijule esikhumbeni futhi ngokuyinhloko zibangela ukuguga ngaphambi kwesikhathi kanye nemibimbi.
-
imisebe ye-UVBkuthinta ubuso besikhumba, okubangela ukushiswa yilanga futhi kudlala indima ekukhiqizweni kwevithamini D.
Isilinganiso se-UVA ne-UVB siyashintsha phakathi nosuku futhi sincike esimweni sezulu, isizini, kanye nendawo.
Imibhede Yokushiswa Kwesikhumba
Imibhede eminingi yesimanje yokushiswa kwesikhumba iyakhipha95–99% imisebe ye-UVAkanye nenani elincane le-UVB. Lo mklamo uhlose ukunciphisa ukusha okusheshayo, kodwa futhi uphumela ekuchayweni okukhulu kwe-UVA okugxilile.
Okubalulekile:Nakuba imibhede yokushiswa yilanga inciphisa ingozi yokushiswa yilanga okubangelwa yi-UVB, ikhulisa kakhulu ukuchayeka kwe-UVA, okuhlobene kakhulu nomonakalo wesikhumba wesikhathi eside.
Ukulawula Ukuqina Nokuchayeka
-
Ukuchayeka elangeniakubikezeleki. Ukumbozwa kwamafu, isikhathi sosuku, kanye ne-latitude konke kuthinta amandla e-UV.
-
Imibhede yokushiswa kwesikhumbaukunikeza okuhlala njalo futhi okuhlala njaloumthamo we-UVA onamandla kakhulungesikhathi esifushane.
Eqinisweni, iseshini yombhede wokushiswa kwesikhumba imizuzu eyi-10-15 ingaveza isikhumba sakhoi-UVA eningi njengehora elilodwa elangeni lasemini.
Lokhu kunamandla kwandisa ingozi yokulimala kwesikhumba okwandayo, ikakhulukazi uma kusetshenziswa njalo.
Izingozi Zempilo: Yikuphi Okuyingozi Kakhulu?
Kokubili imibhede yokushiswa kwesikhumba kanye nokuchayeka elangeni kunezingozi, kodwa ucwaningo luhlala lubonisa ukuthiimibhede yokushiswa kwesikhumba ayiphephile kunokukhanya kwelanga kwemvelo.
Izingozi ezihlanganyelwe zifaka:
-
Ukuguga kwesikhumba ngaphambi kwesikhathi
-
Ukwanda kwe-pigmentation kanye namabala obudala
-
Ingozi eyengeziwe yomdlavuza wesikhumba
Izingozi ezengeziwe ezihlobene nemibhede yokushiswa kwesikhumba:
-
Ingozi ephezulu ye-melanoma, ikakhulukazi uma ukusetshenziswa kuqala ngaphambi kweminyaka engama-35.
-
Ukuwohloka kwe-collagen okusheshayo ngenxa yokuchayeka okuqinile kwe-UVA
Izinhlangano zezempilo emhlabeni wonke zihlukanisa imibhede yokushiswa kwesikhumba njengeokubangela umdlavuza.
Ukubukeka vs Impilo Yesikhumba Yesikhathi Eside
Imibhede yokushiswa kwesikhumba ivame ukukhiqiza:
-
Imibala ekhanyayo nesheshayo, emnyama
-
Umbala olingana kakhulu
Kodwa-ke, le nzuzo yobuhle iza ngezindleko zalokhu:
-
Imibimbi esheshisiwe kanye nokuwa
-
Ukulahlekelwa ukunwebeka kwesikhumba
-
Amathuba akhulayo okulimala kwesikhumba isikhathi eside
Umbala wesikhumba—kungakhathaliseki ukuthi uvela elangeni noma embhedeni wokushiswa kwesikhumba—empeleni uyintouphawu lokulimala kwesikhumba, hhayi impilo yesikhumba.
Ingabe Kukhona Enye Indlela Ephephile Kakhulu?
Kulabo abafuna ukubukeka okune-bronze ngaphandle kokulimala kwe-UV:
-
Imikhiqizo yokushiswa kwesikhumba ngaphandle kwelanga(izifutho, ama-lotion) zinikeza umbala ngaphandle kokuchayeka emisebeni
-
Ukwelashwa kokukhanya okubomvuisetshenziswa kakhulu ezindaweni zempilo yobungcweti ukusekela ukuvuselelwa kwesikhumba ngaphandle kokuvezwa yi-UV
Lezi zinketho azikhulisi ingozi yomdlavuza wesikhumba futhi zibhekwa njengeziphephile empilweni yesikhumba yesikhathi eside.
Isinqumo Sokugcina: Imibhede Yokushiswa Kwelanga Noma Ilanga?
Uma uqhathanisa imibhede yokushiswa kwesikhumba nelanga:
-
Akukho nketho engeyona ingozi
-
Imibhede yokushiswa kwesikhumba ivame ukuchaya abasebenzisiamazinga aphezulu e-UVA agxile kakhulu
-
Ukusebenzisa njalo imibhede yokushiswa kwesikhumba kungandisa ingozi yomdlavuza wesikhumba ngaphezu kokuchayeka elangeni elilinganiselwe
Ukuze isikhumba sibe nempilo, odokotela besikhumba batusa ukunciphisa ukuchayeka emisebeni ye-UV ngokuphelele nokukhetha ezinye izindlela ezingezona eze-UV noma nini lapho kungenzeka.
Imibuzo Evame Ukubuzwa
Ingabe imibhede yokushiswa kwesikhumba iphephile kunelanga?
Cha. Imibhede yokushiswa kwesikhumba ivame ukuletha imisebe ye-UVA enamandla kunokukhanya kwelanga kwemvelo, okwandisa ingozi yokulimala kwesikhumba isikhathi eside.
Ingabe imibhede yokushiswa kwesikhumba iyasiza ngevithamini D?
Iningi lezindawo zokushiswa kwesikhumba likhipha i-UVB encane kakhulu, okwenza zingaphumeleli ekukhiqizweni kwevithamini D.
Ingabe ukusebenzisa imibhede yokushiswa kwesikhumba ngezikhathi ezithile kungaba okuphephile?
Akukho izinga eliphephile ngokuphelele lokushiswa kwe-UV. Ngisho nokuvezwa ngezikhathi ezithile kunomthelela ekulimaleni kwesikhumba okuqhubekayo.
