UNYANGO LOKUKHANYA
Ingasetyenziswa nanini na, kubandakanywa nexesha lasebusuku.
Ingasetyenziswa ngaphakathi, ngasese.
Iindleko zokuqala kunye neendleko zombane
I-spectrum yokukhanya enempilo
Ubunzulu bunokwahluka
Akukho kukhanya kwe-UV okuyingozi
Akukho vitamin D
Kusenokwenzeka ukuba iphucule imveliso yamandla
Yehlisa iintlungu kakhulu
Ayikhokeli ekutshiseni kwelanga
UKUKHANYA KWELANGA KWENDALO
Ayisoloko ikhona (imozulu, ubusuku, njl.njl.)
Ifumaneka ngaphandle kuphela
Ngokwendalo, akukho ndleko
Ukukhanya okunempilo kunye nokungenampilo
Ubunzulu abunakuhluka
Ukukhanya kwe-UV kunokukhokelela kumonakalo wesikhumba njl
Inceda ukuveliswa kwevithamin D
Yehlisa iintlungu ngokuphakathi
Ikhokelela ekukhanyeni kwelanga
Unyango lokukhanya okubomvu sisixhobo esinamandla nesiguquguqukayo, kodwa ngaba kungcono kunokuphumela ngaphandle elangeni?
Ukuba uhlala kwindawo enamafu, esenyakatho ngaphandle kokufikelela okuhambelanayo elangeni, ke unyango olubomvu olubomvu alunangqondo - unyango olubomvu olukhanyayo lunokwenza umlinganiselo ophantsi wokukhanya kwendalo.Kwabo bahlala kwiindawo ezitshisayo okanye kwezinye iindawo eziphantse zibe nokufikelela imihla ngemihla ekukhanyeni kwelanga okunamandla, impendulo inzima kakhulu.
Umahluko ophambili phakathi kokukhanya kwelanga kunye nokukhanya okubomvu
Ukukhanya kwelanga kuqulethe uluhlu olubanzi lokukhanya, yonke indlela ukusuka ekukhanyeni kwe-ultraviolet ukuya kwi-infrared ekufutshane.
Okuqulethwe kukukhanya kwelanga ngamaza asempilweni obomvu kunye ne-infrared (enyusa imveliso yamandla) kunye nokukhanya kwe-UVb (okuvuselela ukuveliswa kwevithamin D).Nangona kunjalo kukho amaza okukhanya ngaphakathi kwelanga ayingozi ngokugqithisileyo, njenge-blue and violet (enciphisa imveliso yamandla kunye nomonakalo wamehlo) kunye ne-UVa (ebangela ukutshisa kwelanga / ukutshisa kwelanga kunye ne-photoaging / umhlaza).Lo mbala obanzi unokuba yimfuneko ekukhuleni kwezityalo, i-photosynthesis kunye nemiphumo eyahlukeneyo kwii-pigments kwiintlobo ezahlukeneyo, kodwa ayizizo zonke izibonelelo kubantu kunye nezilwanyana ezincelisayo ngokubanzi.Esi sizathu sokuba kutheni i-sunscreen kunye ne-SPF ziyimfuneko kwilanga elinamandla.
Isibane esibomvu sisibona-kude esimxinwa, esizimeleyo, esiphakathi kwe-600-700nm – inxalenye encinci yokukhanya kwelanga.Uluhlu lwe-infrared olusebenzayo ngokwebhayoloji ukusuka kwi-700-1000nm.Ngoko ke amaza okukhanya avuselela imveliso yamandla aphakathi kwe-600 kunye ne-1000nm.La maza obude obubomvu kunye ne-infrared aneziphumo eziluncedo kuphela ezingenazo iziphumo ebezingalindelekanga ezaziwayo okanye izinto eziyingozi-ukwenza unyango lwesibane esibomvu lube luhlobo lonyango oluxhalabileyo xa kuthelekiswa nokukhanya kwelanga.Akukho zikhrimu ze-SPF okanye iimpahla ezikhuselayo ezifunekayo.
Isishwankathelo
Eyona meko ilungileyo iya kuba kukufikelela kokubini ilanga lendalo kunye nolunye uhlobo lonyango lwesibane esibomvu.Fumana ukukhanya kwelanga ukuba unako, emva koko sebenzisa isibane esibomvu.
Isibane esibomvu siyaphononongwa malunga nokutshiswa lilanga kunye nokukhawulezisa ukuphiliswa komonakalo wemitha ye-UV.Oku kuthetha ukuba ukukhanya okubomvu kunempembelelo yokukhusela kwingozi enokubakho yokukhanya kwelanga.Nangona kunjalo, ukukhanya okubomvu kukodwa akuyi kuvuselela ukuveliswa kwevithamin D eluswini, into oyifunayo ukukhanya kwelanga.
Ukufumana ukukhanya okuphakathi kwesikhumba ekukhanyeni kwelanga kwimveliso ye-vitamin D, kudibaniswa nokukhanya okubomvu kwonyango ngosuku olufanayo lwemveliso yamandla eselula mhlawumbi yeyona ndlela ikhuselayo.
