Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: Ko te rangahau hauora mo nga paanga o te rama nui ki te tinana o te tangata e kii ana he maha nga paanga kino ki te hauora ka puta mai i te poke rama, i te rama rama ranei, a ko etahi pukapuka hoahoa rama e whakamahi ana i te hauora o te tangata hei paearu tika mo te rama o roto. Ko ngā pānga hauora o te nui o te whakamarama, o te hanganga ā-rangi hē rānei o te marama, ko te: piki ake o te mate mahunga, te ngenge o te kaimahi, te taumahatanga i tautuhia e te rongoā, te heke o te mahi ā-tinana, me te piki ake o te manukanuka. Waihoki, kua rangahauhia nga tauira kararehe e whakaatu ana i te marama e kore e taea te karo ki te whakaputa i te painga kino ki te ahua me te manukanuka. Mo te hunga e hiahia ana kia mataara i te po, he nui te pānga o te marama i te po ki te mataara me te wairua.I te tau 2007, "te mahi huringa e uru ana ki te whakararu i te ra" i whakarārangitia e te World Health Organization's International Agency for Research on Cancer hei mate pukupuku pea. (Pūrongo Panui a IARC Nama 180). He maha nga rangahau i tuhi i te hononga i waenga i te mahi i te po me te piki ake o te mate pukupuku me te mate pukupuku prostate. I kitea e tētahi rangahau i tirotirohia ai te hononga i waenganui i te pānga ki te marama waihanga i te pō (ALAN) me ngā taumata o te mate pukupuku uma i Korea ki te Tonga, ko ngā rohe e whai ana i ngā taumata teitei o ALAN i pūrongo i te maha o ngā take o te mate pukupuku uma. Ko Seoul, ko te taumata teitei rawa o te poke marama, he 34.4% ake nga mate pukupuku u i a Ganwon-do, ko te taumata iti rawa o te poke marama. I tohu tēnei i tētahi pānga nui i waenganui i te ALAN me te maha o te mate pukupuku uma. I kitea hoki kaore he hononga i waenga i etahi atu momo mate pukupuku penei i te mate pukupuku o te kopu me te mate pukupuku ALAN.Ko tetahi korerorero hou (2009), na te Ahorangi Steven Lockley, Harvard Medical School, i kitea i roto i te pukapuka a CfDS "Kua Matapotia e te Maama?". Ko te Upoko 4, "Ko ngā pānga hauora tangata o te poke o te marama" e kī ana "... ko te whakaekenga o te marama, ahakoa he ngoikore, ka taea te ine i nga hua o te raruraru moe me te aukati melatonin. Ahakoa he...  Pātai: He aha ngā tohu e pā ana ki te nui o te whakamarama?
he nui ake te mate o te mate mahunga, te ngenge o te kaimahi, te taumahatanga kua tautuhia e te hauora, te heke o te mahi taatai me te piki ake o te manukanuka
