I te hoko maru, ka whakatuwherahia tonutia e ngā kaihoko te maru kia kite mēnā he "piri hiriwa" kei roto. I te nuinga o te wā, e whakaaro ana tātou ko te "piri hiriwa" he "ātete-UV". Ka ātete rānei i te UV?
Nā, he aha rawa te "piri hiriwa"?
He paparanga te kāpia hiriwa, e whakamahia ana hei whakamarumaru, ehara i te mea hei ārai i te hihi UV.
E ai ki te matotoru o te paninga, ka taea te wehewehe ki te hiriwa tuatahi, te hiriwa tuarua, te hiriwa toru, te hiriwa whā. Ko te nui ake o ngā paparanga paninga, he pai ake te pānga o te atarangi, ka pai ake te āhua o te whakamarumaru. Haunga te kāpia hiriwa, kei reira ngā maru "tae kāpia" me te "pango pango", he pai hoki te pānga o te ārai mārama.
Ina hoki, ko te kaupapa o te maru me te rapa hiriwa i te atarangi, kaua ki te ārai i te UV-UV, engari nā te mea ka ngoikore te urunga o te UV-B, he nui ake te paparanga o te arai tinana o te maru, ko te pānga kotahi ko te ārai i te werawera o te rā.
Engari ko te mea pono, kāore i te tūtohutia kia whakamahia ngā maru me te kāpia hiriwa, mō ngā take e rua.
1. He paninga matū te kāpia hiriwa, ki te mea he kāpia hiriwa pai kia whai kounga whakapumau, engari ko te nuinga o ngā maru iti hei pupuri i ngā utu, ko te kāpia hiriwa he mea peita kia ātaahua te āhua, he ruarua ake pea kei te rā ka ngawari te tuku i ngā matū kino ki te tinana tangata, ki te kore he huarahi hei whakaū i te pai me te kino o te kāpia hiriwa, ngana ki te karo i te whakamahi.
2. Ko te paparanga o roto o te maru me te rapa hiriwa, ka whakaata i te hurihanga o te papa o te hihi ngaru roa, me te pānga kati kōtuhi o te whakaata mutunga kore whakamua, ka uru te wera, ā, ka mau tonu pea te wera ahakoa te pouri!
Nō reira, hei kaiwhakarato maru ngaio, ka whakamahia e mātou he paninga tā UV kounga pai anake mō ā mātou maru. Kāore he matū e tukuna mai i roto i tā mātou maru. Hei tāpiri, he pai ake te paninga pango.
