Kuyini ukukhanya okuluhlaza okwesibhakabhaka?
Ukukhanya okuluhlaza okwesibhakabhaka kuchazwa njengokukhanya okungaphakathi kwebanga lobude be-wavelength obungu-400-480 nm, ngoba ingozi engaphezu kuka-88% yokulimala kwe-photo-oxidative ku-retina okuvela ezibanini ze-fluorescent (cool whie noma "broad spectrum") ibangelwa ubude be-wavelength obuphakathi kuka-400-480 nm. Ingozi yokukhanya okuluhlaza okwesibhakabhaka ifinyelela ku-440 nm, futhi yehla ibe ngu-80% wezinga eliphezulu ku-460 kanye no-415 nm. Ngokuphambene nalokho, ukukhanya okuluhlaza okungu-500 nm kuyingxenye eyodwa kweziyishumi kuphela njengengozi ku-retina kunokukhanya okuluhlaza okwesibhakabhaka okunobude be-wavelength obungu-440 nm.
Yini eyenziwa yi-Blue light therapy emzimbeni?
Ukwelashwa ngokukhanya okuluhlaza okwesibhakabhaka kusebenzisa ubude obuthile bokukhanya, obusukela kuma-nanometer angu-400 kuya kwangu-500 esikalini sikagesi. Lokhu kwelapha izimo zesikhumba ezahlukahlukene ngedivayisi yokwelapha ngokukhanya ekhipha lokho esikubona njengombala oluhlaza okwesibhakabhaka.
Amaseli athile emzimbeni azwela kakhulu ekukhanyeni okuluhlaza okwesibhakabhaka. Lawa ahlanganisa izinhlobo ezithile zamabhaktheriya, okuhlanganisa amabhaktheriya abangela induna kanye namaseli omdlavuza.
Amaza okukhanya okuluhlaza okwesibhakabhaka mafushane kakhulu, ngakho awamunceki kakhulu esikhumbeni futhi ngenxa yalesi sizathu awusizo kakhulu ekwelapheni induna, ukuvuvukala, kanye nezifo ezahlukahlukene zesikhumba.
Futhi inezinzuzo eziningana zokubambisana uma isetshenziswa nokwelashwa kokukhanya okubomvu.
Ukwelashwa Kokukhanya Okuluhlaza okwesibhakabhaka kweMerican: ubude be-wavelength obungu-480 nm
Ukwelashwa ngokukhanya okuluhlaza okwesibhakabhaka kungenye yezindawo zokwelapha ngokukhanya ezithola ukuqashelwa ngokushesha ngezinye zezinzuzo zayo ezimangalisayo ikakhulukazi uma zisetshenziswa kanye nokwelashwa ngokukhanya okubomvu kanye ne-NIR.

Lungisa umonakalo welanga futhi usize ekwelapheni izilonda ezingaphambi komdlavuza
Ukukhanya okuluhlaza okwesibhakabhaka okusetshenziswa ne-ejenti yokwazisa ukukhanya kutholakale kusebenza kahle ekwelapheni ama-keratoses e-actinic noma izilonda ezingaphambi komdlavuza ezibangelwa ukulimala kwelanga. Ukwelapha isilonda se-actinic keratosis ngasinye kungavimbela umdlavuza wesikhumba. Lokhu kwelashwa okuphumelelayo kuhlose kuphela amangqamuzana anesifo ngaphandle komphumela omkhulu ezicutshini ezizungezile.

Induna encane kuya kwephakathi
Ukwelashwa ngokukhanya okuluhlaza okwesibhakabhaka sekuvelele ekunakekelweni kwesikhumba njengokwelashwa okuphumelelayo kwezinduna ezincane kuya kweziphakathi. I-Propionibacterium acnes, igciwane elibangela izinduna, likhipha i-photosensitizer eyenza amagciwane abe nomuzwa wokukhanya kakhulu futhi abe sengozini yokulimala ngenxa yamaza athile.

Amanxeba okulwa nokuguga kanye nesikhumba
Ukujikeleza kwegazi okuhle kubalulekile empilweni yesikhumba kanye nokuphulukiswa kwamanxeba esikhumba. Ukukhanya okuluhlaza okwesibhakabhaka kukhuthaza ukukhishwa kwe-nitric oxide (NO), i-vasodilator ekhulisa ukujikeleza kwegazi ukuze ilethe umoya-mpilo, amangqamuzana omzimba, kanye nezakhamzimba endaweni yokwelashwa. Kanye nezakhiwo zokukhanya okuluhlaza okwesibhakabhaka zokulwa namagciwane kanye nokuvuvukala, lo mphumela ungabangela ukuphulukiswa kwamanxeba okusheshayo kanye nempilo yesikhumba engcono.
