Uyazi ukuba i-sunscreen iyimfuneko ngokupheleleyo kukhuseleko lomhlaza wolusu kunye nokulwa ukuguga. Kodwa enye yeendlela ezisezantsi ze-SPF yemveli kukuba ikwathintela ukukwazi komzimba wakho ukufunxa ivithamin D oyifumana elangeni. (Qinisekisa ukuba awuyi kuwela ezi ntsomi ze-SPF kufuneka uyeke ukukholelwa.) Kude kube ngoku.

Abaphandi baseBoston University Medical Centre baye benza indlela entsha yokuphuhlisa i-sunscreen eya kukukhusela zombini kwimitha eyingozi ngelixa uvumela umzimba wakho ukuba uvelise i-vitamin D. Indlela yabo ichazwe kwiphephancwadi. I-PLOS enye. Uninzi lwee-sunscreen okwangoku kwimarike zikhusela kwimitha ye-ultraviolet A kunye nemitha ye-ultraviolet B, eyokugqibela ekufuneka uvelise kuyo ivithamin D.

Ngokutshintsha iikhompawundi zamachiza, abaphandi badala iSolar D (esele ithengisiwe kwilanga laseOstreliya) ngenjongo yokunceda abantu bafumane ivithamin D engaphezulu yendalo yonke imihla. (Phantse ama-60 eepesenti kuthi okwangoku aswelevithamin D, nto leyo esibeka emngciphekweni wokudakumba kwaye sinyuse amathuba okufumana iintlobo ezithile zomhlaza. B-blockers, ezivumela ulusu lwakho ukuba luvelise ukuya kuthi ga kwi-50 pesenti ye-vitamin D ngaphezulu.

Ingxaki kukuba, ukuvala imitha ye-UVB yinto entle kakhulu. Imitha ye-UVB sisizathu sokuba ufumane ukutshiswa lilanga, kwaye zikwabangela ukuguga ngaphambi kwexesha kunye nomhlaza wolusu. ISolar D isakukhusela uninzi Imitha yelanga ye-UVB kodwa ivumela ubude obuthile bokukhanya ukuba bufikelele kulusu lwakho ukuqala inkqubo ye-vitamin D synthesis.

Ezinye iingcali ziyathandabuza. Kuthatha nje imizuzu embalwa yokuvezwa lilanga ukuze umzimba wakho uvelise ivithamini D oyifunayo yonke imihla, utshilo uSejal Shah, MD ugqirha wesikhumba kwisiXeko saseNew York. Ukuvezwa kakhulu kwe-ultraviolet kunokwaphula ivithamini D emzimbeni wakho.

Ngaba ukufumana ivithamin D ezimbalwa ngakumbi ukuvelisa imitha kulungele umngcipheko wokonakaliswa lilanga ngakumbi xa uphume ubambe imitha imini yonke? Ngokuqinisekileyo akunjalo, ngokuka-Shah. “Ekugqibeleni kukhuselekile ukuthatha isongezelelo sevithamin D kunokuzibeka esichengeni sokukhanya kwelanga kakhulu,” utshilo. Fumana indlela yokukhetha eyona vitamin D isongezelelo. Ukuba unexhala ngenene malunga nokunqongophala kwevithamin D, thetha nogqirha wakho.
