Abantu abaninzi bakholelwa ukuba iibhedi zokuthambisa isikhumba yindlela "elawulwayo" yokufumana umbala okhanyayo xa kuthelekiswa nokulala phantsi kwelanga. Kodwa ngaba iibhedi zokuthambisa isikhumba zikhuselekile ngokwenene? Uphando lubonisa okwahlukileyo koko: iibhedi zokuthambisa isikhumba zinokukubeka kwimitha ye-ultraviolet (UV) enamandla ngakumbi kunelanga, nto leyo ebenza babe sengozini enkulu kulusu lwakho nakwimpilo yakho iyonke.
1. Indlela Esebenza Ngayo Ukushiswa Kwelanga
Ukukhanya kwelanga: Ilanga livelisa zombini imitha ye-UVA kunye ne-UVB. I-UVA ingena nzulu eluswini kwaye ibangele ukwaluphala, ngelixa i-UVB ibangela ukutsha kodwa ikwakhuthaza ukuveliswa kwevithamini D.
Iibhedi zoKuthambisa: Izixhobo zokwenziwa ezikhupha imisebe ye-UVA ikakhulu, zihlala zikwizinga eliphezulu kunelanga lasemini. Ezinye iimatshini zongeza i-UVB, kodwa umlinganiselo awungowendalo.
2. Kutheni iibhedi zokutshisa ilanga zingakhuselekanga
Ukuvezwa ngamandla kwi-UVA: Iseshoni enye yokuthambisa ilanga inokulingana neeyure ezininzi zokutshiswa lilanga.
Umngcipheko ophezulu womhlaza: Ukusetyenziswa kwebhedi yokuthambisa isikhumba kunxulunyaniswa nokwanda kwamazinga e-melanoma, i-basal cell carcinoma, kunye ne-squamous cell carcinoma.
Akukho zibonelelo zevithamini D: Ngokungafaniyo nokukhanya kwelanga kwendalo, iibhedi zokuthambisa azincedi umzimba wakho ukuba uvelise ivithamini D ngokufanelekileyo.
Ukwaluphala kwangethuba: I-UVA ikhawulezisa ukuguga kolusu, nto leyo ekhokelela ekubeni imibimbi, ukugoba, kunye nombala.
3. Imvumelwano yeengcali
I-World Health Organization (WHO) kunye ne-American Academy of Dermatology (AAD) zibeka iibhedi zokuthambisa isikhumba njenge-Group 1 carcinogen - udidi oluphezulu lomngcipheko, olufana nolwecuba kunye ne-asbestos.
Akukho bungakanani bokutshiswa kwesikhumba ngaphakathi endlwini obuthathwa “njengokhuselekileyo.”
Imibuzo Ebuzwa Rhoqo - Ngaba iibhedi zokutshisa ilanga zikhuselekile kunelanga?
1. Ngaba iibhedi zokuthambisa zikhuselekile kunokukhanya kwelanga kwendalo?
Hayi. Iibhedi zokutshisa umbala zihlala zikuchanaba kwimitha ye-UVA exineneyo, ebangela umonakalo kwi-DNA kwaye yonyusa umngcipheko womhlaza ngokukhawuleza kunelanga.
2. Zingaphi iiseshoni zokulala ngelanga ezilingana nelanga?
Iseshoni enye yemizuzu eli-10-15 yokuthambisa i-darnishing bed ingazisa ukukhanya kwe-UV okufanayo nokweeyure ezi-2-3 elangeni elinamandla emini.
3. Ngaba iibhedi zokuthambisa isikhumba zingakunika i-vitamin D?
Hayi. Iibhedi zokuthambisa isikhumba zikhupha i-UVA, nto leyo engayibangeliyo i-vitamin D. I-UVB yelanga iyafuneka koku.
4. Ingaba ukutshiswa kwelanga endlini kukhuselekile kuba "kuyalawulwa"?
Hayi. Nokuba kwindawo elawulwayo, imitha ye-UV inamandla kwaye ithe ngqo, nto leyo eyenza iibhedi zokuthambisa zibe yingozi ngakumbi kunezo zangaphandle.
5. Ngaba iibhedi zokutshisa umbala welanga ziyaludala ulusu lwakho ngokukhawuleza?
Ewe. Imitha ye-UVA yonakalisa i-collagen kunye ne-elastin, ibangela imibimbi engaphambi kwexesha, imigca emincinci, kunye namabala okuguga.
6. Ngaba ibhedi enye yokuthambisa ilanga ingakulimaza?
Ewe. Uphando lubonisa ukuba iseshoni enye nje iyakwandisa umngcipheko womhlaza wolusu, kwaye ukusetyenziswa rhoqo kuyawunyusa kakhulu umngcipheko we-melanoma, ingakumbi ngaphambi kokuba ufikelele kwiminyaka engama-35 ubudala.
7. Yeyiphi indlela ekhuselekileyo yokuthambisa isikhumba?
Eyona ndlela ikhuselekileyo ziimveliso zokuthambisa ngaphandle kwelanga ezifana neeloshini zokuthambisa ezizitshisayo, izitshizi, kunye neebronzers, ezibonelela ngenkangeleko yegolide ngaphandle kokuvezwa yi-UV.
