Ukwelashwa ngokukhanya okubomvu kusakazeka emhlabeni wonke wokunakekelwa kwesikhumba. Kusukela kumadivayisi asekhaya kuya emitholampilo yobungcweti, kusukela ekwelashweni kokuguga kanye nokwelashwa kwama-acne kuya ekulungisweni kwesikhumba okubucayi, kuvela ezixazululweni cishe zazo zonke izidingo zokunakekelwa kwesikhumba futhi sekuyinto ethandwayo ezinkundleni zokuxhumana. Kodwa yini eyenza lokhu kukhanya okubomvu okubonakala kunamandla kube yindlela entsha ethandwayo yokunakekelwa kwesikhumba?
Ukukhanya kuvela elangeni. Ukukhanya kwelanga akulona umbala owodwa, kodwa kungahlukaniswa kube imibala eyisikhombisa ebonakalayo: obomvu, o-orenji, ophuzi, oluhlaza okotshani, oluhlaza okwesibhakabhaka, o-indigo, no-violet. Umehluko wabo usezilinganisweni zamaza abo—uma ubude bamaza bude, umbala uthambekela kakhulu kubomvu; uma ubude bamaza bufushane, kulapho buthambekela kakhulu kubomvu.Ukukhanya okubomvu kutholakala ekugcineni kwe-long-wave length ye-spectrum yokukhanya okubonakalayo, kanye nobubanzi be-wavelength obungaba ngu-630nm-780nm.Lokhu ukuhlukaniswa kwemvamisa okukhona ngendlela ehlelekile ngaphakathi kwe-spectrum ye-electromagnetic.
Ngenxa yezimpawu zayo "zamagagasi amade", ukukhanya okubomvu kunamandla amakhulu okungena kanye nesimo samandla esizinzile, okuvumela ukuthi kungene kalula ebusweni besikhumba futhi kufinyelele ezicutshini ezingaphansi kwesikhumba ngaphandle kokubangela ukucasuka okukhulu ezicutshini zezinto eziphilayo. Ucwaningo oluhlobene noProfesa Michael Hamblin weHarvard Medical School luqinisekisile ukuthi ukukhanya okubomvu kungangena ezicutshini zomuntu kuze kube sekujuleni okungaphezu kwama-30mm. Lesi sici sinikeza ukukhanya okubomvu inzuzo yemvelo ekusetshenzisweni kobuhle, ukuvuselelwa, ngisho nasensimini yezokwelapha.
Ngaphezu kwalokho, inani eliyingqayizivele lokwelashwa kokukhanya okubomvu kokunakekelwa kwesikhumba licaca nakakhulu uma liqhathaniswa nezindlela zendabuko.Ukunakekelwa kwesikhumba kwendabuko kulandela kakhulu indlela "yangaphandle", ikakhulukazi ehilela ukungenelela kwangaphandle ngezithako zamakhemikhali.
Ngokuphambene nalokho, ukukhanya okubomvu kuyindlela yamandla angokwenyama. Akungezi ngqo noma yiziphi izinto esikhumbeni, kodwa kunalokho kuvuselela imisebenzi yamangqamuzana kanye namandla avela ngaphakathi ngokudlulisela izimpawu zamandla ezithile kumaseli. Le nqubo ibizwa ngokuthi i-photobiomodulation.
Uma ukukhanya okubomvu kungena ku-dermis, kuhlasela ngqo i-mitochondria ngaphakathi kwamaseli. Lapho imunca amandla okukhanya, i-mitochondria yandisa 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 nemikhiqizo engcolile, kanye nokulawula izimpendulo zokuvuvukala. Le miphumela yokusebenzisana ndawonye iletha izinzuzo eziningi zokunakekelwa kwesikhumba, okuhlanganisa ukulwa nokuguga, ukulungisa, imiphumela yokulwa nokuvuvukala, kanye nokukhanyisa isikhumba, konke okuqinisekiswe yizifundo eziningi zezokwelapha.
I-Merican ibilokhu igxile kakhulu emkhakheni wezempilo nobuhle bokukhanya iminyaka eyi-17. Ngokusekelwe ocwaningweni olujulile ngamandla okukhanya okubomvu nemiphumela yawo ye-photobiological, nangokulawulwa okunembile kobude be-wavelength yokukhanya okubomvu kanye nokuqina kokukhishwa kwamandla, kuhlanganiswe nomklamo we-ergonomic kanye nezinhlelo zokulawula ukukhanya ezihlakaniphile, i-Merican isungule ukwelashwa kwe-phototherapy okuhlanganisiwe kokubili kobuso nomzimba, yandisa izinzuzo zokunakekelwa kwesikhumba kokukhanya okubomvu kusukela ebusweni kuya emzimbeni wonke.
Kuyaphawuleka ukuthi ukusungula izinto ezintsha kweMerican kudlulela ngale komthombo owodwa wokukhanya; kungahlanganisa ngokwesayensi amaza amaningi okukhanya anembile ukuze kufezwe imiphumela yokusebenzisana, ngaleyo ndlela kudale izixazululo zempilo nobuhle bokukhanya ezisebenza kahle kakhulu neziphelele zezinkinga zesikhumba eziningi.
Ukwelashwa ngokukhanya okubomvu kuvuselela amandla angaphakathi esikhumba kusetshenziswa amandla ahlanzekile angokwenyama. Imvelo yayo ephephile, ephumelelayo, futhi engahlaseli yenza kube ukukhetha okuthembekile kwabaningi abathanda ubuhle. I-Mericon yandisa izinzuzo zokwelashwa ngokukhanya okubomvu kuwo wonke umzimba, ivula isici esisha ekufuneni impilo nobuhle.
