Imitha yelanga ibangela ukonakala kolusu-Naxa ungaphakathi

Kuyavela ukuba, ilanga linokuba namandla ngakumbi kunokuba besicinga: imitha ye-ultra-violet (UV) iyaqhubeka nokonakalisa ulusu lwethu kwaye yandisa umngcipheko wethu womhlaza kangangeeyure ezine emva kokuba sifudukele ngaphakathi, uphando olutsha oluvela kwiYunivesithi yaseYale lubonisa.

Ngelixa i-melanin, i-pigment kwiiseli zolusu, kudala kukholelwa ukuba ikhusela ulusu kwimitha ye-UV eyingozi, iziphumo ezitsha zibonisa ukuba amandla yenza ukufunxeka kunokufakwa kamva kwizicubu ezijikelezileyo, kubangele utshintsho kwiDNA ekufutshane enokubangela umhlaza. Ngelixa oku kuyadimazayo, ukufumanisa kunokubangela ukukhula kwe "lotion emva" kwezinto ezinokunceda ukunciphisa isiphumo. Okwangoku, i-dermatologists icebisa ukunxiba i-sunscreen ekhusela ilanga (i-SPF) ye-15 okanye ngaphezulu enika ukhuselo lobubanzi obubanzi kwimitha ye-UVA kunye ne-UVB. (Kwaye qiniseka ukuba uyifunda ngocoselelo ilebhile: Iingxelo zabathengi Ithi amanye ama-Sunscreen e-SPF Amabango ayichanekanga.)

Cinga ukuba ungatsiba isiqhelo selanga kude kube lihlobo? Hayi ngokukhawuleza. Phezu kwako nje ukubanda, iintsuku ezimnyama zasebusika, ulusu lwakho lusafuna ukukhuselwa. Ubuninzi beepesenti ezingama-80 zemitha yelanga ye-UV isadlula emafini, kwaye uhlala ubethwa yile mitha kabini, njengoko ikhephu kunye nomkhenkce ubonakalisa ukubuyela kwakho kulusu-lokubeka umngcipheko womhlaza wolusu kunye nemibimbi. Amaxesha okuqandisa nawo ashiya ulusu lomile kwaye lucaphukile, lusenza sengozini yokukhanya okuluqatha kwe-UV.

Ukukhuselwa unyaka wonke, slather kwi-sunscreen ubuncinci imizuzu eyi-15 ngaphambi kokuphuma ngaphandle. Zama iinketho zethu ezizithandayo kwiiMveliso zoKhuseleko lweLanga ezigqwesileyo zika-2014 okanye iingcebiso zokhuseleko lwelanga ezikhankanywe kwiiNgcebiso zaseBusika ezisuka kwi-X-Games Stars.
