Kusukela kumadivayisi okunakekela isikhumba ekhaya kuya ekwelashweni kochwepheshe be-salon, kusukela ekwelashweni kokuguga kanye nokwelashwa kwezinduna kuya ekulungisweni kwesikhumba okubucayi, kubonakala sengathi kunikeza ikhambi cishe kuzo zonke izidingo zokunakekelwa kwesikhumba. Eqinisweni, sekuyinto ethandwayo kangangokuthi manje sekuxoxwa ngayo kakhulu ezinkundleni zokuxhumana. Kodwa yini eyenza lokhu kukhanya okubomvu okubonakala kunamandla kube "into ethandwayo" entsha yokunakekelwa kwesikhumba?

Kuyini ukukhanya okubomvu?
Ukukhanya kuvela elangeni. Kodwa ilanga alilona nje umbala owodwa. Lingahlukaniswa ngemibala eyisikhombisa yokukhanya esingayibona: obomvu, o-orenji, ophuzi, oluhlaza okotshani, oluhlaza okwesibhakabhaka, i-indigo kanye ne-violet. Umehluko usezindleleni zazo zokukhanya - uma ubude bokukhanya bude, umbala uba bomvu kakhulu; uma ubude bokukhanya bufushane, umbala uba luhlaza okotshani kakhulu. Ukukhanya okubomvu kutholakala ekugcineni okude kokukhanya okubonakalayo, okunobubanzi bokukhanya obungaba ngu-630nm-780nm. Lokhu ukuhlukaniswa kwemvelo ku-spectrum ye-electromagnetic.
Ukukhanya okubomvu kunobude obude be-wavelength. Lokhu kusho ukuthi kungangena ngokujulile esikhumbeni ngaphandle kokubangela ukucasuka okukhulu ezicutshini zezinto eziphilayo. UProfesa Michael Hamblin weHarvard Medical School uthole ukuthi ukukhanya okubomvu kungangena ngama-30mm noma ngaphezulu ezicutshini zomuntu. Lokhu kwenza ukukhanya okubomvu kube ukukhetha okuhle kokwelashwa kobuhle, ukuvuselelwa, ngisho nokwelapha.

Ukunakekelwa kwesikhumba okubomvu VS izindlela zendabuko
Ngaphezu kwalokho, inani eliyingqayizivele lokunakekelwa kwesikhumba okubomvu liyacaca uma liqhathaniswa nezindlela zendabuko. Ukunakekelwa kwesikhumba kwendabuko kulandela kakhulu indlela 'yangaphandle', evame ukuhilela ukungenelela kwangaphandle 'ngezithako zamakhemikhali.'
Ukukhanya Okubomvu, ngokwako, kuyindlela yamandla angokwenyama. Akungezi ngqo noma yiziphi izinto esikhumbeni, kodwa kunalokho kuvuselela imizwa yamangqamuzana kanye namandla avela ngaphakathi, ngokudlulisela izimpawu zamandla ezithile kumaseli. Le nqubo yaziwa ngokuthi umthethonqubo we-photobiological.
Uma ukukhanya okubomvu kungena ku-dermis, kuhlose ngqo i-mitochondria ngaphakathi kwamaseli. Lapho imunca amandla okukhanya, i-mitochondria ithuthukisa kakhulu ukusebenza kahle kokwenziwa kwe-ATP, ibangela uchungechunge lwezimpendulo zamakhemikhali: ukusheshisa ukukhiqizwa kwe-collagen ne-elastin, ukuthuthukisa imetabolism yamaseli, ukusheshisa ukususwa kwama-free radicals kanye nokungcola, kanye nokulawula izimpendulo zokuvuvukala. Le miphumela yokusebenzisana ngokubambisana ifinyelela izinzuzo eziningi zokunakekelwa kwesikhumba, okuhlanganisa ukulwa nokuguga, ukulungisa, ukulwa nokuvuvukala, kanye nokukhanyisa, konke okuqinisekiswe yizifundo eziningi zezokwelapha.

UMerican wayengumholi wokunakekelwa kwesikhumba okukhanyayo okubomvu umzimba wonke.
I-Merican ibilokhu ihileleke kakhulu emkhakheni wezempilo nobuhle bokukhanya iminyaka eyi-17. Ngokusekelwe ocwaningweni olujulile mayelana nokulawulwa kwamandla kanye ne-photobiological kokukhanya okubomvu, ifinyelele ukunakekelwa okuhlanganisiwe kwe-phototherapy kobuso nomzimba ngokulawula ngokunembile ubude be-wavelength kanye namandla okukhishwa kokukhanya okubomvu, kuhlanganiswe nomklamo we-ergonomic kanye nesistimu yokulawula ukukhanya okuhlakaniphile, ukuze izinzuzo zokunakekelwa kwesikhumba zokukhanya okubomvu zikwazi ukusabalala kusukela ebusweni kuya emzimbeni.
Kuhle ukusho ukuthi ukusungula izinto ezintsha kweMerican kudlulela ngale komthombo owodwa wokukhanya. Kungahlanganisa ngokwesayensi amaza amaningi, anembile okukhanya ukuze kufezwe imiphumela yokusebenzisana, ngaleyo ndlela kudale ikhambi lezempilo nobuhle elisebenza kahle kakhulu neliphelele 'elifanela bonke' lezinkinga zesikhumba eziningi.
Ukunakekelwa Kwesikhumba Okubomvu kuvuselela amandla angaphakathi esikhumba ngamandla ahlanzekile omzimba. Imvelo yayo ephephile, ephumelelayo, futhi engahlaseli yenza kube ukukhetha okuthembekile kwabathandi bobuhle. I-Merican yandisa izinzuzo zokukhanya okubomvu kuwo wonke umzimba, ivula isahluko esisha ekuphishekeleni impilo nobuhle.
