Kwaye ukuba ngokwenene usabetha phezulu iibhedi zokushuka? Abantu bayavuma ukuba ngokuzithemba okufanayo, ukugigitheka benetyala abakusebenzisayo xa behlangabezana nokutshaya icuba lakho ngamanye amaxesha. (Kubi!)
Uninzi lwezizathu abantu abazisebenzisayo ukuchaza ukuba kutheni beyiphepha i-sunscreen ayisasebenzi ngokujonga ngcono nge-tan (iteknoloji ye-tan ye-fake ifikile ukuza kuthi ga ngoku), ilanga linceda ukumisa ama-acne (ayinyani; ukuthintela ilanga kukubheja okungcono); I-sunscreen ivakala imbi kakhulu (awukayifumani i-SPF efanelekileyo kuwe-jonga ezi zikhetho zingama-20). Kodwa kukho enye esabonakala isemthethweni: eso sikhuseli selanga sithintela ukukwazi kolusu lwakho ukufunxa imitha enceda umzimba wakho wenze uhlobo olusebenzisekayo lwevithamin D. Kwaye sihlaselwe iminyaka ngoku ngeendaba malunga nokuba inkulu kangakanani ivithamin D. Uphando lubonakalisile ukuba luyanceda ukunciphisa umzimba, ukusebenza kwezemidlalo, kunye nokunye. Kodwa ziluncedo ke kulungile ukuba kufanelekile ukuba umngcipheko wokuyeka i-SPF?
UDarrell Rigel, MD, uprofesa wezonyango kwiziko lezonyango laseNew York, uthi hayi. "Ihlala ihlawula ukuzikhusela elangeni. Siyazi ukuba kukho umngcipheko wokuba nomhlaza wolusu ukuba ufumana ilanga kakhulu," ucacisa. "Kwaye ewe, i-sunscreen iyanciphisa inani lemitha ye-UVB efikelela kulusu lwakho, ethi yona igcine ulusu lwakho lungaguquki ivithamin D ibe luhlobo olusebenzayo. Kodwa kukho iqela lezinye iindlela zokufumana ivithamin D eyaneleyo ngaphandle kokuzibeka emngciphekweni umhlaza wolusu. "
Eyona ndlela ilula: Thatha nje isongezelelo sevithamin D ukuze ukwazi ukuhlangana kwi-SPF ngaphandle kokucinga nokuba yeyiphi idosi ye-D ngqo oyifumanayo. (Nantsi indlela yokukhetha eyona ilungileyo.) Okanye utye ukutya okunevithamin D (okufana nezi zisibhozo).
Inyani yile, nangona kunjalo, awunakude ufune ukutya kwakho. Akukho mntu unxiba i-sunscreen ngokugqibeleleyo, utshilo uRigel. Abantu banxiba kancinci kakhulu, okanye baphinde bafake isicelo rhoqo, ke amathuba okuba, ubonakaliswe ubuncinci abanye Imitha ye-UVB nokuba yintoni na. "Nokuba unxibe i-SPF ephezulu kwaye uyifaka rhoqo, ufumana imitha ye-UVB kwimisebenzi yemihla ngemihla njengokuhamba usuka emotweni yakho usiya evenkileni, ke ngoko uguqula ivithamin D," uyongeza.
