Abantu abaningi bacabanga ukuthi ukulala elangeni ngaphandle kokugcoba ilanga kuyingozi kakhulu kunokusebenzisa umbhede wokushiswa kwelanga. Eqinisweni,imibhede yokushiswa kwesikhumba ingaba yingozi efanayo—noma ibe yimbi nakakhulu—kunokukhanya kwelanga okungavikelekile, kuye ngokuthi ubukhali kangakanani, ubude besikhathi, kanye nobuningi besikhathi.
Imisebe ye-UV: Inkinga Eyinhloko
Kokubili imibhede yokushiswa kwesikhumba kanye nokukhanya kwelanga kuveza isikhumba sakhoimisebe ye-ultraviolet (UV), okulimaza amangqamuzana esikhumba kanye ne-DNA.
-
Ukukhanya kwelanga:Ikhipha ingxube ye-UVA ne-UVB
-
Imibhede yokushiswa kwesikhumba:Ukukhiphai-UVA egxile kakhulu, ngokuvamile ngamandla aphezulu kakhulu
I-UVA ingena ngokujulile esikhumbeni futhi idlala indima enkulu kulokhu:
-
Ukuguga ngaphambi kwesikhathi
-
Imibimbi
-
Ukulahlekelwa ukunwebeka kwesikhumba
-
Ingozi yomdlavuza wesikhathi eside
Kungani Imibhede Yokushiswa Kwelanga Ingaba Yimbi Kakhulu
Uma kuqhathaniswa nokukhanya kwelanga kwemvelo ngaphandle kokuvikela ilanga, imibhede yokushiswa kwesikhumba ivame:
-
Hambisaimithamo ye-UVA enamandla ngesikhathi esifushane
-
Ukungabi nezimpawu zemvelo zokuxwayisa (ukushisa, ukungakhululeki)
-
Khuthaza izikhathi zokudalulwa eziphindaphindwayo
-
Dala umuzwa wamanga wokulawula nokuphepha
Iseshini eyodwa yokulala ngesikhumba ingase iveze isikhumba ku-i-UVA eningi njengehora elilodwa lelanga lasemini.
Ukuqhathaniswa Kwengozi Yomdlavuza Wesikhumba
Ucwaningo luhlala lubonisa:
-
Ukusebenzisa njalo imibhede yokushiswa kwesikhumba kwandisa kakhulu ingozi ye-melanoma
-
Ukuchayeka kakhulu ku-UVA kusheshisa ukulimala kwesikhumba okuhlanganayo
-
Ingozi ikhuphuka kakhulu lapho ukushiswa kwesikhumba kuqala esemncane
Ukuchayeka elangeni ngaphandle kokuzivikela kuyingozi—kodwaukuvezwa kwe-UV okwenziwe ngokwemvelo kuhlukaniswa njengokubangela umdlavuzayiziphathimandla ezinkulu zezempilo.
Umugqa Ophansi
Yebo,umbhede wokushiswa kwesikhumba ungaba mubi kakhulu kunelanga ngaphandle kokhilimu welanga, ikakhulukazi uma isetshenziswa njalo noma ngendlela engafanele. Kokubili kuyingozi ngaphandle kokuvikelwa, kodwa imibhede yokushiswa kwesikhumba iyalethaimisebe ye-UV enamandla kakhulu, egxililengesikhathi esincane.
Imibuzo Evame Ukubuzwa
Ingabe ukushiswa kwesikhumba endlini kuphephile kunokukhanya kwelanga ngaphandle?
Cha. Ukushiswa kwesikhumba endlini akuphephile futhi kungandisa ingozi yomdlavuza.
Ingabe i-sunscreen yenza imibhede yokushiswa kwesikhumba iphephe?
I-sunscreen inciphisa ukusha kodwa ayiqedi umonakalo we-UV.
