Nazi mfundo zingapo zofunika zansalu yotchinga dzuwa:

Chitetezo cha UV: Nsalu zotchingira dzuwa zimapangidwira kuti zitseke kapena kuchepetsa kulowerera kwa ma radiation a UV kudzera muzinthuzo.Izi zimathandiza kuteteza khungu kuti lisapse ndi dzuwa, kukalamba msanga, komanso kuwonongeka kwa nthawi yayitali chifukwa cha kuwala kwa UV.

Mulingo wa UPF: Mulingo wa UPF umayesa kuchuluka kwa ma radiation a UV omwe amaloledwa kudutsa munsalu.Mwachitsanzo, nsalu yokhala ndi mlingo wa UPF wa 50 imalola 1/50 (kapena 2%) ya ma radiation a UV kuti alowe, kupereka chitetezo cha dzuwa.

Kupuma: Ngakhale kuti nsalu zoteteza dzuwa zimakhala zogwira mtima potsekereza kuwala kwa UV, zimatha kusiyanasiyana malinga ndi kupuma.Nsalu zina zingathandize kuti mpweya uziyenda bwino, zomwe zingathandize wovalayo kuti azizizira komanso azimasuka m’nyengo yotentha.

Ntchito: Nsalu zodzitetezera ku dzuwa zimagwiritsidwa ntchito popanga zovala ndi zinthu zina monga zipewa, malaya, mathalauza, zosambira, ndi zida zakunja.Amakonda kwambiri zochitika zapanja monga kukwera mapiri, kusambira, ndi masewera komwe kumakhala kodetsa nkhawa ndi dzuwa.

Ndikofunika kuzindikira zimenezonsalu zoteteza dzuwasizozimitsa moto kapena zosagwira moto.Ngati mukufuna zinthu zosagwira moto, muyenera kuganizira nsalu zomwe zimapangidwira cholinga chimenecho, zomwe ndi zosiyana ndi zomwe zimapangidwira kuti ziteteze ku dzuwa.

Nsalu zosagwira moto zimakonzedwa kapena kupangidwa kuti zisapse ndi moto komanso kuti zichepetse kufalikira kwa malawi.Nsaluzi zimagwiritsidwa ntchito povala zovala zotetezera ozimitsa moto, ogwira ntchito m'mafakitale, ndi malo ena omwe ali pangozi.

Komano, mafuta oteteza ku dzuwa ndi mankhwala oteteza khungu ku dzuwa.Amapezeka mu mawonekedwe a mafuta odzola, mafuta odzola, opopera, kapena ndodo zomwe zimagwiritsidwa ntchito pakhungu.
