Kutheni Ukwenziwa ulusu Okungakumbi kuthetha ukuba Ukuncipha kweVithamin D

Umxholo

• Uphengululo lwe

"Ndifuna ivithamin D yam!" sesinye sezizathu eziqhelekileyo ezinikelwa ngabasetyhini ngokusukwa. Kwaye kuyinyani, ilanga ngumthombo olungileyo wevithamini. Kodwa oko kunokusebenza kuphela ukuya kuthi ga kwinqanaba, ngokophando olutsha lokufumanisa ukuba umsuki nguwe, ivithamin D encinci ulusu lwakho luthatha kwilanga.

IVithamin D iye yachazwa njengeminerali engummangaliso kule minyaka yakutshanje ngenxa yetoni yezifundo ezibonisa ukuba yomeleza amajoni akho omzimba, ikhusela amathambo akho, ilwa nomhlaza, yehlisa isifo sentliziyo, yonyusa ukusebenza kwezemidlalo, inciphisa ukudakumba, kwaye ikunceda ukuba ulahlekelwe. ubunzima. Ukuqinisekisa ukuba ufumana u-D owoneleyo yenye yezona zinto zibalaseleyo onokuzenza kwimpilo yakho-kwaye indlela elula yokufumana ukukhanya ngaphandle kwewindow yakho.

Kodwa ngokutsho kwabaphandi abavela eBrazil, ilizwe elaziwa ngokuthanda ulusu olucekiswe lilanga (hi, Giselle!), Unxibelelwano lwe-vitamin D-tanning luyinkimbinkimbi. Nantsi indlela esebenza ngayo: Xa uphumela ngaphandle ngaphandle kwelanga, imitha ye-UVB evela elangeni ibangela ukusabela kulusu lwakho ukuvumela iiseli zakho zolusu ukuba zivelise ivithamin D. Abantu abanesikhumba esikhanyayo bafuna nje imizuzu elishumi ngemini ukufumana isabelo sabo semihla ngemihla ngelixa abantu Isikhumba esimnyama sidinga imizuzu eli-15 ukuya kwengama-30 ngemini, ngokweBhunga likaVitamin D. (Ndisafuna khangela tan? Fumana esona sixhobo sibalaseleyo sokuzithuna ukuze silungele indlela ophila ngayo.)

Nantso ke ingxaki. Isikhumba esimnyama ngokwendalo sithatha imitha embalwa ye-UV-B, ekhokelela ekubeni ibe novithamini omncinci. Kwaye okukhona uselangeni, iba mnyama isikhumba sakho. Ke ngoku xa u-tan ungaphezulu, uvithamini D omncinci ufumana ngaphandle.

Ngombulelo kulusu lwabo olunombala, ngaphezulu kwama-70 eepesenti abantu besifundo bebenqongophele ku-vitamin D-kwaye lelinye lawona mazwe anelanga ehlabathini! Isisombululo sendalo sinokubonakala sifumana ilanga elingakumbi ngoko. Ngelishwa, njengoko ixesha lingakhuselekanga elangeni lisanda, nawo umngcipheko womhlaza wolusu-inani lokuqala lokubulala abantu abangaphantsi kweminyaka engama-40 ubudala. (I-Eek! Abantu basathengela ngaphandle kokunyuka kwamaxabiso eMelanoma.)

Impendulo, njengemiba emininzi yezempilo, iphakathi, bathi abaphandi. Fumana ilanga elaneleyo ukuze ufumane isabelo sakho semihla ngemihla-kwaye ugqume nge-sunblock kunye/okanye nempahla ekhuselayo ye-UV.
