Kwiintsuku ezimbalwa, amaqondo obushushu sele enyukile kwaye inxenye usingasiqithi bekusokola kakhulu ehlotyeni kunentwasahlobo. Kubalulekile ke ngoko ukuba uzikhusele elangeni kwaye uphephe iingxaki zolusu ezizayo.
Imitha ye-Ultraviolet ingunobangela wezi ngxaki kubalulekile ukuba wazi ukuba ziqulathe ntoni kwaye zithini iingcebiso zokukhusela ulusu kwizenzo zalemitha.
Imitha ye-Ultraviolet okanye i-UV luhlobo lwamandla ekhutshwa lilanga kwaye ingena kumphezulu woMhlaba.. Zimbini iintlobo zemitha yelanga: UV-A kunye ne-UV-B. Uhlobo lokuqala lwemitha lunokungena nzulu eluswini kwaye luyingozi kakhulu. njengoko inokukhokelela kumhlaza wolusu owoyikekayo.
Kwimeko ye-UV-B, ayingeni kangako kwaye yimitha ebangela ubomvu kunye nokonakala kolusu, okubangela ukutsha kwelanga okudumileyo. Kuyangqinwa ngokwenzululwazi ukuba ukubonakaliswa okuphezulu kolusu kukusebenza kwelanga sesona sizathu siphambili somhlaza wolusu. Kungenxa yoko le nto kufuneka kuthintelwe ngalo lonke ixesha ukuba imitha ye-UV ingene kulusu kwaye kubangela umonakalo omkhulu.
Kubaluleke kakhulu ukuba ukhumbule ukuba kufuneka uphephe ukuthambisa ilanga kwiiyure ezisemini kwaye khusela ulusu ngekhrim ethile ekunceda ukuba uyinyamekele ngokugqibeleleyo. Ngoku ukuba imozulu entle ilapha kwaye uninzi lwabantu luyathontelana ukuya elunxwemeni nakumachibi okudada ukuze ube nexesha elimnandi kwaye wonwabele imozulu elungileyo, kubalulekile ukukhathalela imitha ye-UV eyingozi. Khumbula ukuzikhusela ngokugqibeleleyo kwaye ke uthintele iingxaki zesikhumba zexesha elizayo ezinokuthi zingalungiseki kwaye zibe nzulu.
