Kufakazelwa ukuthi abantu abanombala wezinwele obomvu banezinga eliphansi le-Vitamin K, elinomthelela kumanxeba okuphulukisa, futhi, ngenxa yalokho, ukugcwala ngegazi elimpofu. Kanye nokuhlanganiswa okungenamkhawulo kwe-Red-haid - umzimba wabo uhlanganisa i-Vitamin D eningi, eyehlisa kakhulu ingozi yokuthola izifo zamathambo, njenge-osteoporosis kanye nama-rickets. Lababantu kufanele babe ngaphansi kweLanga futhi bahlale besebenzisa ukhilimu wokuvikela: Feomelain ka-Pigment ngaphansi kwemisebe ye-ultraviolet ithinta isikhumba ngendlela yamahhala efaka isandla ekuthuthukisweni komdlavuza wesikhumba (i-melanoma). Lesi sitatimende asilungile sezinwele ezibomvu kuphela, kodwa futhi nakubantu abangabakwa-Phototype wokuqala nowesibili (ngesikhumba esikhanyayo, izinwele ezimhlophe noma izinwele ezikhanyayo).
Isikhumba ngokwaso sinikeza amasiginali engozi - hlola ngokucophelela ama-moles akho. Chitha i-axis ecabangayo ngakunye kwawo. Izohlukanisa i-mole "enhle" ibe izingxenye ezimbili zokulinganisa. Ema-moles aphephile, ukuphazamiseka kubushelelezi futhi bushelelezi, umbala awunamsebenzi. Uma uke wabona ukufakwa kombala okuhlukile (ngokwesibonelo, amachashazi amnyama avela ku-mole elikhanyayo) okungenzeka ukuthi angenziwa lutho nge-mole. The Molenia morenia, akhuphuka amathuba awo okuphenduka ku-melanoma. Ukuvela kwanoma yiziphi izinguquko zangaphandle (ama-crust, imifantu, ukukhonkotha, ukopha) kufanele kukwazise.
