Ruzhinji rwe Zvirwere kuti mhuka idzi dzinogona kutambura, dzinokonzerwa nekushomeka kwezvakatipoteredza, izvo zvinogona kumuka kubva mumvura, kungave nekuti tembiricha yadzo haina kunaka kana nekuda kwekuti iri mune yakashata mamiriro, uyezve nekuda kwechikafu kana kushomeka kwehutano, kana paine kushomeka mamwe mavitamini, calcium, pakati pevamwe. Chimwe chezvirwere zvakajairika zvemakamba kupofomara, maduku madiki achinyanya kutambura nawo.
Upofu, inoumbwa nekuvharirwa mumaziso kana kuvhara zvakafanana, zvinokonzerwa neimwe mhando yekuzvimba uyezve nekuomesa kweimwe remaziso ako. Inogona zvakare kukonzerwa neimwe mhando yekudzikira mumaziso ayo, izvo zvinoita kuti zvisakwanise kuti mhuka ivhure. Nenzira iyi, hupofu pakutanga hwaisazofanira kukanganisa maziso. Muzviitiko zvakawanda, kunyangwe bofu, maziso aigona kuramba aine hutano hwakakwana, nekuti anenge akavharirwa pasi peimwe remaziso avo, ndosaka zvichizotadza kuti vaone. Asi kana kamba ikapofomara, yaisakwanisa kupa chikafu, yaisazokwanisa kuwana chikafu, uye yaigona kufa nenzara.
Pakati pe zvinokonzera upofu zvinhu zvinoverengeka zvinowanikwa. Chekutanga pane zvese, chimwe chezvinhu chinogona kukanganisa mhuka iyi pombi kana pombi yemvura. Sekuziva kwedu tese, mvura inobuda mupombi ine huwandu hwakawanda hwechlorine, chinhu chinokuvadza zvakanyanya kune idzi mhuka diki. Ndechikonzero cheichi chikonzero, kuti tinokurudzira kune imi mose mune kamba kumba, kana kuti munoronga kuva neimwe, kuti panzvimbo pekushandisa mvura yemupombi, shandisai mvura isina kuiswa klorini kana kurapa mvura yemupombi neimwe mhando yeantichloro.
Nekudaro, ichi handicho chega chikonzero chekupofumadza mumakamba, nekuti maziso avo anogona zvakare kukanganiswa nechirwere ichi kana vasina vhitamini A yakakwana mumuviri wavo, kana vachitambura kubva kune imwe mhando ye fungal chirwere, kana kungoti kana fungi ikatanga kuoneka munzvimbo yavo inokanganisa uye inopisa maziso avo.
