Cov khoom ntsuas kev laus no yog hais txog cov txheej txheem ntawm kev sim ntau ntau yam cuam tshuam txog qhov siv cov khoom siv tiag tiag los ua kom tiav qhov xwm txheej sib zog ntxiv qhov kev sim ntawm kev laus ntawm cov khoom. Cov kev sim yog feem ntau rau cov ntaub ntawv yas. Hom kev laus feem ntau suav nrog kev laus lub teeb thiab ntxooj cua sov laus. Huab cua kub laus.
Cov khoom lag luam raug rau lub hnub ci rau ntev ntev thaum siv sab nraum zoov. Yog tias koj xav paub lub neej ntawm cov khoom lag luam thaum nws tuaj yeem siv sab nraum zoov, nws yog qhov tsim nyog yuav tsum tau sim lub hnub ci ultraviolet lub teeb rau UV kev sim. Tau kawg, kev siv ntau ntawm kev sim tau ntau dua li qhov tseeb siv sab nraum zoov lub teeb, yog li ua kom luv lub sijhawm ntsuas, Koj tuaj yeem nkag siab txog qhov kev laus ntawm cov khoom tom qab ntau xyoo siv los ntawm kev sim luv.
Zoo sib xws, yog tias cov khoom siv hauv qhov chaw noo xws li chav da dej nrog qhov kub siab, nws yuav tsum tau kho kom sov thiab laus dua. Yog tias cov khoom siv raug siv rau hauv qhov chaw ua kom sov tawm ntawm lub tshuab ua haujlwm, nws yuav tsum raug rau cov huab cua kub laus. Ntawm chav kawm, yuav muaj cov qauv coj ua qauv raws li cov khoom lag luam xa tawm mus rau txawv teb chaws thiab thaj chaw.
