KA LAAU MALAMALAMA
Hiki ke hoʻohana i kēlā me kēia manawa, me ka pō.
Hiki ke hoʻohana i loko o ka hale, ma kahi pilikino.
ʻO ke kumu kūʻai mua a me nā kumukūʻai uila
ʻO ke ʻano olakino olakino
Hiki ke ʻokoʻa ka ikaika
ʻAʻohe kukui UV pōʻino
ʻAʻohe huaʻai D
Hiki ke hoʻonui i ka ikehu
Hoemi loa i ka eha
ʻAʻole ia e alakaʻi i ka ʻulaʻula o ka lā
KA LALA OLA
ʻAʻole i loaʻa i nā manawa a pau (ka wā, ka pō, etc.)
Aia ma waho wale nō
Kūlohelohe, ʻaʻohe kumu kūʻai
Maikaʻi a maikaʻi ʻole ke ʻano o ka mālamalama
ʻAʻole hiki ke hoʻololi i ka ikaika
Hiki i ke kukui UV ke alakaʻi i ka pōʻino o ka ʻili, etc
Kōkua i ka hana ʻana o ka huaora D
Hoʻemi maʻalahi ka ʻeha
Alakaʻi i kahi ʻulaʻula o ka lā
ʻO ka lāʻau lapaʻau ʻulaʻula kahi mea hana ikaika a maʻalahi, akā ʻoi aku ka maikaʻi ma mua o ka hele wale ʻana i waho i ka lā?
Inā noho ʻoe i kahi pōʻeleʻele, ʻĀkau me ka loaʻa ʻole o ka lā, a laila ʻo ka ʻulaʻula ʻulaʻula he mea no-brainer - hiki i ka lāʻau ʻulaʻula ke hoʻopau i ka liʻiliʻi o ka mālamalama maoli i loaʻa. No ka poʻe e noho ana i ka ʻāina wela a i ʻole nā kaiapuni ʻē aʻe me ka loaʻa ʻana o ka lā ikaika i kēlā me kēia lā, ʻoi aku ka paʻakikī o ka pane.
ʻO nā ʻokoʻa nui ma waena o ka lā a me ke kukui ʻulaʻula
Loaʻa i ka lā ka laulā o ka mālamalama, mai ke kukui ultraviolet a hiki i ka infrared kokoke.
Aia i loko o ka spectrum o ka lā nā nalu olakino o ka ʻulaʻula a me ka infrared (e hoʻonui ai i ka hana ikehu) a me ke kukui UVb (e hoʻoulu ai i ka hana ʻana o ka huaora D). Eia nō naʻe, aia nā hawewe nalu i loko o ka lā i ʻoi aku ka pōʻino, e like me ka uliuli a me ka violet (e hoʻemi ana i ka hoʻoulu ʻana o ka ikehu a hōʻino i nā maka) a me UVa (no ka mea e ʻā ai ka lā/ka lā a me ke kiʻi ʻana/kani). Pono paha kēia ākea ākea no ka ulu ʻana o ka mea kanu, photosynthesis a me nā hopena like ʻole i nā puaʻa ma nā ʻano ʻano like ʻole, akā ʻaʻole pono ia no nā kānaka a me nā mammals ma ka laulā. ʻO kēia ke kumu e pono ai ka sunblock a me SPF sunscreens i ka lā ikaika.
ʻO ke kukui ʻulaʻula kahi kikoʻī liʻiliʻi a kaʻawale, ma kahi o 600-700nm - kahi hapa liʻiliʻi o ka lā. Nā pae infrared biologically mai 700-1000nm. No laila, ʻo nā nalu nalu o ka mālamalama e hoʻoulu i ka hana ikehu ma waena o 600 a me 1000nm. ʻO kēia mau hawewe ʻulaʻula a me ka infrared he mau hopena maikaʻi wale nō me ka ʻike ʻole ʻia o nā hopena ʻaoʻao a i ʻole nā mea ʻino - e hana ana i ka ʻulaʻula ʻulaʻula he ʻano hopohopo ʻole o ka lāʻau i hoʻohālikelike ʻia i ka ʻike ʻana o ka lā. ʻAʻole koi ʻia nā ʻaila SPF a i ʻole nā lole pale.
Hōʻuluʻulu manaʻo
ʻO ke kūlana maikaʻi loa ka loaʻa ʻana o ka lā maoli a me kekahi ʻano o ka lāʻau ʻulaʻula. E kiʻi i ka lā inā hiki iā ʻoe, a laila e hoʻohana i ke kukui ʻulaʻula ma hope.
Ua aʻo ʻia ke kukui ʻulaʻula e pili ana i ka sunburn a me ka wikiwiki o ka ho'ōla ʻana i ka pōʻino o ka radiation UV. ʻO ke ʻano o ke kukui ʻulaʻula he hopena pale i ka pōʻino o ka lā. Eia naʻe, ʻaʻole hiki i ke kukui ʻulaʻula wale ke hoʻoulu i ka hana ʻana o ka huaora D i ka ʻili, kahi āu e pono ai ka lā.
ʻO ka loaʻa ʻana o ka ʻili haʻahaʻa i ka lā no ka hana ʻana i ka huaora D, i hui pū ʻia me ka lāʻau ʻulaʻula ʻulaʻula i ka lā hoʻokahi no ka hana ʻana o ka ikehu kelepona ʻo ia paha ke ala palekana loa.
