Ingubo Yokwelapha Ukukhanya Okubomvu Uma Iqhathaniswa Nengubo Yokushisa Ejwayelekile: Uyini Umehluko?

Kungakhathaliseki ukuthi unesifiso sokufunda ngamagajethi akamuva ezempilo noma uzama nje ukunquma ukuthi iyiphi ingubo ezokusekela kangcono ukulala kwakho nokululama, lesi sihloko sikuqondisa ngomehluko obalulekile phakathi kwemikhiqizo emibili efana kakhulu. Omunye usebenzisa ukukhanya kuma-wavelength athile ukuze akhuthaze izinqubo zamaseli, kanti omunye uthembele ekududuzeni okulula nokujwayelekile kokushisa. Ukuqonda ukuthi ngayinye isebenza kanjani, ukuthi imiphi imiphumela empeleni elethayo, nokuthi ingena kuphi emisebenzini yansuku zonke kanye nokucabangela kwezokwelapha kuzokusiza wenze ukukhetha okuqinisekile.

Ngezansi uzothola izincazelo ezicacile ezichaza izindlela, izinzuzo, imibuzo yokuphepha, umehluko osebenzayo, kanye nezici zokwenza izinqumo. Uma ufuna ukwazi ukuthi yikuphi okungasiza imisipha yakho ebuhlungu, ukuthuthukisa isikhumba sakho, ukunciphisa ubuhlungu obungapheli, noma nje ukukusiza ulale kangcono ebusuku obubandayo, izigaba ezilandelayo zizokunikeza umongo nemininingwane eyanele yokulinganisa izinketho ngokucabangela.

Indlela ezisebenza ngayo: isayensi ngemuva kwezingubo zokwelashwa ngokukhanya okubomvu kanye nezingubo zokufudumala ezijwayelekile

Izingubo zokwelashwa kokukhanya okubomvu kanye nezingubo zokufudumala ezijwayelekile zisebenza ngezimiso zomzimba ezihlukene ngokuphelele, yize zombili zithengiswa ukuze kuthuthukiswe induduzo kanye nenhlalakahle ngezinye izikhathi. Ingubo yokwelashwa kokukhanya okubomvu empeleni iyiqoqo lama-diode akhipha ukukhanya (ama-LED) aletha ubude besikhathi obuthile bokukhanya okubomvu nokuseduze kwe-infrared esikhumbeni nasezicutshini ezingaphezulu. Indlela eyinhloko esetshenziswa abakhiqizi futhi isekelwa ucwaningo lwelabhorethri yi-photobiomodulation. Ekuguqulweni kwe-photobiomodulation, ama-photon amuncwa ama-chromophore ngaphakathi kwamaseli—ikakhulukazi yi-enzyme i-cytochrome c oxidase ku-mitochondria, edlala indima eketheni lokuthuthwa kwama-electron. Lapho la ma-chromophore emunca ukukhanya ebangeni elibomvu kuya kwe-infrared, kungaba khona uchungechunge lwezimpendulo zamaseli: umsebenzi owandisiwe we-mitochondrial kanye nokukhiqizwa kwe-ATP, ukuguqulwa kwezinhlobo ze-oxygen ezisebenzayo, ukudluliselwa kwesignali yeselula okuthuthukisiwe okuhlobene nokulungiswa nokukhula, kanye nokushintsha kwabaxhumanisi bokuvuvukala. Imiphumela eyisisekelo yomzimba eye yabonwa ezifundweni ezahlukahlukene ifaka phakathi ukulungiswa kwezicubu okusheshayo, izimpawu zokuvuvukala ezincishisiwe, ukukhiqizwa kwe-collagen okwandisiwe esikhumbeni, kanye nokuguqulwa kwezindlela zokubonisa ubuhlungu.

Ngokuphambene nalokho, ingubo yokufudumeza ejwayelekile incike ezintweni zokufudumala eziqinile ezifakwe ngaphakathi kwendwangu ukuze ikhiqize amandla okushisa. Ingubo iphakamisa isikhumba, futhi, ngezinga elincane, izinga lokushisa lezicubu zendawo. Lokhu kunyuka kwezinga lokushisa kubangela ukuvaleka kwegazi—ukwanda kwemithambo yegazi—okungakhulisa ukugeleza kwegazi endaweni, kusheshiswe ukususwa kwemikhiqizo ye-metabolic, futhi kunciphise ukuqaqamba kwemisipha ngemiphumela ekusebenzeni kwemisipha ye-neuromuscular. Ukushisa kunikeza nenduduzo yezinzwa, kusebenze izimpendulo zokulawula ukushisa, futhi kunganciphisa ukuqina okubonakalayo. Le miphumela ngokuvamile ayiqondile futhi yesikhashana: uma ingubo isusiwe futhi izicubu zipholile, izinzuzo ezisheshayo zobuhlungu noma ukuqina okuncishisiwe zivame ukuphela.

Ukujula kokungena kungenye into ehlukanisayo. Ukukhanya okuseduze kwe-infrared kungangena esikhumbeni nasezicutshini ezingajulile kakhulu kunokukhanya okubomvu, kufinyelele emisipheni nasemalungeni ngezinga elithile, kanti ukushisa okumelana nakho kufudumeza kakhulu izicubu ezingaphezulu kanye nokujula okuncane kwezicubu ezingaphansi kuye ngokuthi ubude kanye nokushisa bungakanani. Ukuqina, ubude be-wavelength, kanye nomthamo wamandla aphelele kunquma umthelela webhayoloji wokukhanya okubomvu nokuseduze kwe-infrared, futhi lezi zici ziyahlukahluka kakhulu phakathi kwamadivayisi. Izingubo zokufudumeza zilawula ukulethwa kokushisa ngezilungiselelo zokushisa ezilungisekayo, izikhathi, kanye nokunqunywa kokuphepha. Ngamafuphi, izingubo zokuphulukisa ukukhanya okubomvu zizama ukushintsha ukusebenza kweseli ngqo ngokusebenzisana okuqondiwe kwe-photonic, kuyilapho izingubo zokufudumeza zinikeza impumuzo yezimpawu ngokushintsha izinga lokushisa lendawo kanye nokujikeleza kwegazi.

Izinzuzo zokwelapha kanye nalokho okushiwo ubufakazi ngendlela ngayinye

Uma kuqhathaniswa izinzuzo zokwelapha, kusiza ukuhlukanisa ukukhululeka okusheshayo kwezimpawu ezishintshayo ezihlala isikhathi eside. Izingubo zokufudumeza ezijwayelekile ziphumelela kakhulu ekukhululekeni okusheshayo nokubonakalayo: zifudumeza umzimba, zithobe imisipha eqinile, futhi zingasiza abantu ukuba balale ngokushesha noma bazizwe bekhululekile endaweni ebandayo. Ngokwemvelo, ukushisa kunganciphisa ukuqaqamba kwemisipha, kunciphise ukuqina kwamalunga okwesikhashana, futhi kudale umuzwa wokuphumula. Kwabaningi, ingubo yokufudumeza iyithuluzi eliphumelelayo lokuqeda ubuhlungu besikhashana, ukuphathwa kwe-strain yokuya esikhathini, kanye nokuthuthukisa induduzo ngesikhathi sokuphumula. Ubufakazi bokwelashwa kokushisa ezimweni ze-musculoskeletal budedengu futhi busebenza kakhulu: izivivinyo ezilawulwa ngokungahleliwe kanye neziqondiso zokwelapha zivame ukuncoma ukushisa okungaphezulu njengendlela yokugcina, enobungozi obuphansi bokungakhululeki kwemisipha okubukhali nokungapheli, ikakhulukazi uma kusetshenziswa kanye nezinye izindlela zokwelapha njengokwelula noma ukuzivocavoca.

Nokho, izingubo zokulala zokukhanya okubomvu zihlose ukushintshashintsha kwezinto eziphilayo ngale kokufudumala okulula. Ucwaningo olukhulayo mayelana nokuguqulwa kwe-photobio lukhombisa izinzuzo ezingaba khona zokuphulukiswa kwenxeba, ukunciphisa ukuvuvukala, ukuthuthukiswa kokubukeka kwesikhumba (njengemigqa emincane kanye nokuthungwa), kanye nokunciphisa ubuhlungu ezimweni ezithile ezingamahlalakhona. Izifundo kubadlali zibonisa ukululama okusheshayo ekulimaleni kwemisipha okubangelwa ukuzivivinya kanye nokunciphisa ubuhlungu bemisipha obuqala ukubambezeleka lapho kusetshenziswa amaza okukhanya kanye nemithamo efanele. Izifundo zesikhumba zibonisa ukwakheka kwe-collagen okuthuthukisiwe kanye nethoni yesikhumba ngezinqubo ezithile. Ngezifo zobuhlungu obungamahlalakhona, ezinye izivivinyo zibike ukuthuthuka okukhulu ebuhlungwini nasekusebenzeni, kodwa imiphumela ingaba engafani ngoba imingcele yedivayisi, isikhathi sokwelashwa, kanye nezimo ziyahlukahluka kuzo zonke izifundo.

Kubalulekile ukuqaphela imikhawulo ebufakazini. Izifundo eziningi zisebenzisa amadivayisi ebanga lomtholampilo anemingcele ethile yokukhanya kanye nemingcele ye-wavelength, kanti izingubo zokulala zezinga lomthengi ziyahlukahluka kakhulu ekukhanyeni kwazo, ukuhambisana kwe-wavelength, kanye nomthamo olethwayo. Umthamo ubalulekile: kokubili ukungabonakali kahle kanye nokubonakala ngokweqile kunganciphisa izinzuzo ezingaba khona, futhi imingcele yokwelapha efanele iseyindawo yocwaningo olusebenzayo. Ngaphezu kwalokho, imiphumela ye-placebo ingaba nkulu ebuhlungwini kanye nemiphumela eqondene nomuntu, ngakho-ke izivivinyo zekhwalithi ephezulu ezine-blinding eyanele zibalulekile ukuhlola ngokugcwele ukusebenza kahle. Ngamafuphi, izingubo zokulala zokufudumeza zinikeza impumuzo ebikezelwayo, esheshayo ngokusebenzisa izindlela zokushisa ezinezinzuzo ezisebenzayo ezisungulwe kahle. Izingubo zokulala zokukhanya okubomvu zinikeza ukwelashwa okuthembisayo, okunokwenzeka ngokwebhayoloji kokulungisa izicubu, ukuguqulwa kokuvuvukala, kanye nokululama, kodwa ukusebenza kahle kuncike kakhulu kwikhwalithi yedivayisi kanye nomthamo ofanele.

Izinto okufanele uzicabangele ngokuphepha, izithiyo, kanye namaphrofayili engozi yenketho ngayinye

Ukuphepha kuyisici esibalulekile lapho ukhetha phakathi kwengubo yokwelapha ngokukhanya okubomvu nengubo yokushisa ejwayelekile, ngoba zombili zinezingozi ezihlukile kanye nokuphikisana. Ngengubo yokushisa ejwayelekile, izingozi eziyinhloko ukusha kokushisa, ukushisa ngokweqile, kanye namaphutha kagesi angaba khona. Abantu abanomuzwa wokushisa ophansi—njengalabo abane-peripheral neuropathy ngenxa yesifo sikashukela noma ukulimala komgogodla—bangase bangaboni amazinga okushisa akhuphukayo, okubabeka engcupheni enkulu yokusha. Abantu asebekhulile abanesikhumba esincane kanye nezinsana nabo basengozini enkulu. Ukusebenzisa ingubo yokushisa ubusuku bonke noma lapho belele kwandisa ingozi yokuchayeka isikhathi eside. Izingubo zokushisa zanamuhla zivame ukufaka izici zokuphepha njengemikhawulo yokushisa ephezulu, izibali-sikhathi zokuvala okuzenzakalelayo, kanye nokuvikelwa kokushisa ngokweqile, kodwa abasebenzisi kumele balandele imiyalelo yomkhiqizi futhi bahlole umkhiqizo njalo ukuze babone ukuthi izintambo zonakalisiwe noma ziyaqhekeka.

Izingubo zokwelashwa ngokukhanya okubomvu zinikeza izinto ezahlukene zokucatshangelwa ngokuphepha. Ukushintshashintsha kwe-photobiomedulation kumithamo yokwelapha ngokuvamile kubhekwa njengokuphephile kubantu abaningi, futhi ama-LED awakhiphi imisebe ye-ultraviolet eyingozi ehlotshaniswa nokwelashwa kokukhanya okuthile. Kodwa-ke, ukuvikelwa kwamehlo kuyalulekwa uma usebenzisa amadivayisi anamandla aphezulu, ikakhulukazi ngamaza okukhanya aseduze kwe-infrared angabonakali kodwa angathinta izicubu ze-retinal. Izibani ezikhanyayo noma ezishaywayo zingabangela ukuquleka okuzwela ukukhanya kubantu abasengozini, nakuba ukwelashwa kwe-LED okuqhubekayo okunamandla aphansi kunamathuba amancane okwenza kanjalo. Enye inkinga yokuphepha ukuzwela ukukhanya okubangelwa imithi; ama-antibiotic athile, ama-retinoids, noma izithasiselo zamakhambi kwandisa ukuzwela kwesikhumba ekukhanyeni futhi kungabhebhethekisa imiphumela emibi uma kuhlanganiswa ne-phototherapy. Abantu abakhulelwe nalabo abanezifo zomdlavuza ezisebenzayo kufanele baxhumane nabahlinzeki bezempilo ngaphambi kokusebenzisa i-photobiomedulation ngokwezokwelapha, njengoba isiqondiso sezokwelapha siyahlukahluka futhi imiphumela ezimweni ezithile isacwaningwa.

Kukhona futhi umbuzo wobuqotho bedivayisi kanye nokukhishwa kwe-electromagnetic. Izingubo zokufudumeza zingakhiqiza amasimu kagesi aphansi futhi kufanele zigcinwe kude nama-pacemaker kanye namadivayisi afanayo uma isiqondiso somkhiqizi sibonisa kanjalo. Izingubo zokuphulukisa ezibomvu zikhipha amasimu kagesi aphansi kakhulu kodwa zikhiqiza ukushisa njengomkhiqizo olandelayo; ukusetshenziswa okungafanele kusengakhiqiza amazinga okushisa esikhumba aphezulu. Zombili izinhlobo zezingubo zokulala akufanele zisetshenziswe ezimweni ezimanzi noma ngenkathi zilele ngezintambo ezikhululekile eziletha ingozi yokuklinywa noma yomlilo.

Ngokuphathelene nokusebenzisana namadivayisi ezokwelapha noma izifakelo, ngokuvamile kuwukuhlakanipha ukubonisana nodokotela ngaphambi kokuqala ukwelashwa okusha. Abantu abathatha imithi ethinta ukukhanya, labo abanamadivayisi ezokwelapha kagesi afakwelo, kanye nabantu abanezifo ezingalawuleki zesistimu kufanele bathole iseluleko somuntu siqu. Sekukonke, uma kusetshenziswa kahle futhi kusetshenziswa izinyathelo zokuphepha ezifanele, kokubili ukwelashwa kokukhanya okubomvu kanye nezingubo zokufudumeza kungaphephile; umehluko usezinhlotsheni zokuqapha ezidingekayo kuzo zonke izindlela.

Umehluko ongokoqobo: ukusetshenziswa kwansuku zonke, ukulungiswa, isikhathi eside, kanye nezindleko
