Ushwankathelo

Ulusu lusebenzisa ukukhanya kwelanga ukunceda ukuvelisa ivithamin D, ebalulekileyo ekwakheni amathambo aqhelekileyo. Kodwa kukho ukungahambi kakuhle. Ukukhanya kwelanga kwe-ultraviolet kunokubangela umonakalo omkhulu kulusu. Uluhlu lwangaphandle lolusu luneeseli eziqulathe i-pigment melanin. I-Melanin ikhusela ulusu kwimitha yelanga ye-ultraviolet. Ezi zinokutshisa ulusu kwaye zinciphise ukuqina kwazo, nto leyo ekhokelela ekubeni umntu aguge ngaphambi kwexesha.

Abantu tan kuba ukukhanya kwelanga kubangela ukuba ulusu luvelise ngakumbi i-melanin kwaye lube mnyama. I-tan iyaphela xa iiseli ezintsha zihambela phezulu kwaye iiseli ezinesikhumba ziye zacinywa. Ukukhanya kwelanga kunokuba kuhle ukuba ukhuselekile ngokufanelekileyo ekuvezeni kakhulu. Kodwa i-ultraviolet eninzi, okanye i-UV, ukuvezwa kunokubangela ukutshiswa lilanga. Imitha ye-UV ingena kulusu lwangaphandle kwaye ibetheke ngakumbi kulusu, apho inokonakalisa okanye ibulale iiseli zolusu.

Abantu, ngakumbi abo bangenayo i-melanin eninzi kwaye batshiswa lilanga ngokulula, kufuneka bazikhusele. Ungazikhusela ngokugubungela iindawo ezibuthathaka, unxibe isithintelo selanga, unciphise ixesha lokuvezwa lilonke, kwaye uphephe ilanga phakathi kwe-10 kusasa kunye ne-2 pm

Ukuvezwa rhoqo kwimitha ye-ultraviolet kwiminyaka emininzi sesona sizathu siphambili somhlaza wolusu. Kwaye umhlaza wolusu akufuneki uthathwe kancinci.

Jonga ulusu lwakho rhoqo ukukhula okukrokrisayo okanye olunye utshintsho lolusu. Ukufunyanwa kwangoko kunye nonyango zizinto eziphambili kunyango oluyimpumelelo lomhlaza wolusu.
