Kubonakaliswa ukuba abantu abanombala weenwele ezibomvu banamanqanaba aphantsi evithamini K, enomdla wokuphilisa amanxeba, kwaye, ngenxa yoko, igazi elihlwempuzekileyo. Kwaye ke plus ngokungagungqiyo red-iinwele - imizimba yabo synthesizes eninzi ivithamin D, leyo kunciphisa kakhulu umngcipheko wokuba izifo ithambo, ezifana kwamathambo kunye yamathambo. Aba bantu kufuneka babe ngaphantsi kwelanga kwaye bahlala besebenzisa i-cream ekhuselweyo: I-pigment damomelain phantsi kwemitha ye-ultraviolet ichaphazela ulusu olunjalo lomhlaza womhla wolusu (i-phumelanoma). Le ngxelo ezifanelekileyo kuphela obomvu-iinwele, kodwa abantu sokubandakanyeka phototype wokuqala nowesibini (ngesikhumba ukukhanya, zimhlophe okanye iinwele ukukhanya-rusia, eluhlaza, angwevu okanye aluhlaza).
Ulusu lwayo lunika imiqondiso enobungozi - jonga ngononophelo kwii-moles zakho. Chitha i-axis yomfanekiso kwi-axis nganye nganye. Iyahlulahlula i-mole "elungileyo" ibe ngamacandelo amabini. Kwi-moles ekhuselekileyo, i-edges igudileyo kwaye igudile, umbala uhamba gwenxa. Ukuba uqaphela ukubandakanyeka ezahlukeneyo zemibala (umzekelo, amachaphaza amnyama avela kwimole ye-SHICE), ubukhulu becala akukho nto inokwenziwa ngemole. Okukhona iMolenia enkulu, amathuba aphezulu awo aguqukele kwi-phulanoma. Inkangeleko yalo naluphi na utshintsho lwangaphandle (ii-crus, rocks, ukuphosa, ukopha) kuya kukulumkisa.
