Konke odinga ukukwazi ngokukhetha isambulela esifanele esilwa ne-UV
Isambulela selanga siyadingeka ehlobo lethu, ikakhulukazi kubantu abesaba ukushuka, kubaluleke kakhulu ukukhetha isambulela selanga esihle. Kodwa-ke, akuzona kuphela izambulela ezingenziwa ngezindwangu ezihlukahlukene, kodwa futhi ziza ngemibala ehlukahlukene futhi zinemiphumela ehluke kakhulu yokuvikela ilanga. Ngakho isiphi isambulela sombala esihle? Ungakhetha kanjani isambulela sokuvikela ilanga kakhulu? Okulandelayo, ngizokunikeza ngokuhlaziywa kwesayensi kokuthi imuphi umbala isambulela selanga esiwukuvikela kakhulu ilanga, futhi wabelane ngamathiphu okuthi ungalithenga kanjani ilanga ligcwele, bheka.
Ngokwemiphumela yokuhlolwa ye-Chinese Academy of Measurement Science, umbala wendwangu nawo udlala indima ekuvinjweni kwelanga le-UV. Uma kuba mnyama, izinga lokudlulisela le-UV lincane kanye nokusebenza okungcono kokuvikela kwe-UV. Ngaphansi kwezimo ezifanayo, umbala wendwangu uba mnyama, kuba ngcono ukusebenza kwe-anti-UV. Uma kuqhathaniswa, omnyama
Uma kuqhathaniswa, omnyama, osolwandle, oluhlaza okotshani okukhanyayo, opinki okhanyayo, ophuzi okhanyayo, njll. umphumela we-UV womgodi muhle.
Isambulela selanga indlela yokukhetha ukuvikela ilanga kakhulu
Izambulela ezinkulu zingavimba cishe u-70% wemisebe ye-ultraviolet, kodwa azikwazi ukuhlukanisa impahla ebonisiwe ngaphandle komugqa.
Izambulela ezivamile nazo zingavimba imisebe eminingi ye-UV, njengoba kushiwo ngenhla, umbala wesambulela uba mnyama, kuba ngcono. Kodwa-ke, uma ukhetha ilanga elikhulu elinokuvikela kwe-UV, udinga ukucabangela izici ezihlukahlukene, njengentengo, izinga lokuvikela. Indwangu yesambulela nokunye, ukuze ukwazi ukuthenga isambulela esithembekile.
Bheka inani
Ezinye izambulela zingakwazi ukuvala imisebe yelanga kuphela, futhi imisebe ye-ultraviolet isazongena endwangu, kuphela ngemva kokuba ukwelashwa kokuvikela i-sunscreen kube nomthelela wokulwa ne-UV. Ngakho akulona isambulela uzokwazi UV isivikelo. Isambulela esifanelekayo, sokuvikela i-UV, izindleko okungenani ezingama-yuan angama-20. Ngakho-ke sebenzisa amadola ambalwa ukuthenga isambulela, ukusebenza kahle kokuvikelwa kwe-UV kuyangabazeka.
Bheka izinga lokuvikela
Kuphela uma inani lesici sokuvikela i-UV likhulu kuno-30, okungukuthi i-UPF30+, futhi izinga lokudlulisela i-UV yamagagasi amade lingaphansi kuka-5%, lingabizwa ngokuthi imikhiqizo yokuvikela i-UV; futhi uma i-UPF>50, ikhombisa ukuthi umkhiqizo unokuvikela okuhle kakhulu kwe-UV, izinga lokuvikela limaki UPF50+. Uma likhulu inani le-UPF, kuba ngcono ukusebenza kokuvikela kwe-UV.
