He taputapu kaha, he maha hoki ngā whakamahinga o te whakaora rama whero, engari he pai ake i te haere noa ki waho ki te rā?
Ki te noho koe i te taiao kapua, raki hoki, kāore e taea te uru atu ki te rā, he māmā noa iho te rongoā rama whero – ka taea e te rongoā rama whero te whakakapi i te iti o te mārama taiao e wātea ana. Mō te hunga e noho ana i ngā taiao pārūrū, i ētahi atu taiao rānei e tata ana ki te uru atu ki te rā kaha i ia rā, he uaua ake te whakautu.
Ngā rerekētanga matua i waenga i te hihi o te rā me te mārama whero
He whānuitia te whānuitanga o te māramatanga o te rā, mai i te mārama ultraviolet ki te mārama tata-infrared.
Kei roto i te whānuitanga o te rā ngā roangaru hauora o te whero me te whero-whero (e whakarei ake ana i te whakaputanga pūngao) me te mārama UVb (e whakaoho ana i te whakaputanga huaora D). Heoi, kei roto i te whānuitanga o te rā he kino te nui, pērā i te kikorangi me te waioleto (e whakaiti ana i te whakaputanga pūngao me te kino ki ngā kanohi) me te UVa (e puta ai te wera o te rā/te parauri o te rā me te koroheketanga o te whakaahua/te mate pukupuku). Tērā pea he mea nui tēnei whānuitanga whānui mō te tipu o ngā tipu, te whakaahua-whakaahua me ngā pānga rerekē ki ngā tae i roto i ngā momo momo rerekē, engari kāore i te pai katoa mō te tangata me ngā kararehe whāngai whānui. Koinei te take e hiahiatia ai ngā ārai rā me ngā ārai rā SPF i te wā e kaha ana te rā.
He whāiti ake te whānuitanga o te mārama whero, he motuhake, tata ki te 600-700nm – he wāhanga iti noa iho o te hihi o te rā. Ko te whānuitanga o te hihi pūwhero kaha koiora kei waenganui i te 700-1000nm. Nō reira, ko ngā roangaru o te mārama e whakaoho ana i te whakaputanga pūngao kei waenganui i te 600 me te 1000nm. He pānga pai anake ēnei roangaru motuhake o te whero me te pūwhero, kāore he pānga taha, he wāhanga kino rānei e mōhiotia ana – ka waiho te whakaora rama whero hei momo whakaora kore āwangawanga ki te whakatauritea ki te pānga o te rā. Kāore he kirīmi SPF, he kākahu tiaki rānei e hiahiatia ana.
Whakarāpopototanga
Ko te mea tino pai ko te whai wāhi atu ki te hihi o te rā maori me ētahi momo rongoā rama whero. Mēnā ka taea, me whakamahi i te rama whero i muri iho.
E rangahauhia ana te mārama whero e pā ana ki te wera o te kiri me te tere ake o te whakaora i ngā kino o te hihi UV. Ko te tikanga he pānga tiaki te mārama whero i ngā kino ka puta mai i te hihi o te rā. Heoi, kāore te mārama whero anake e whakaoho i te hanga huaora D i roto i te kiri, e hiahiatia ana te hihi o te rā.
Ko te whiwhi i te whitinga rā i te kiri i roto i te āhua taurite hei whakaputa huaora D, me te rongoā rama whero i te rā kotahi hei whakaputa pūngao pūtau pea te huarahi tino tiaki.
