Ukususela kwizixhobo zokhathalelo lolusu lwasekhaya ukuya kunyango lweengcali zesalon, ukusuka ekulweni nokwaluphala kunye nonyango lwe-acne ukuya ekulungisweni kolusu olunobuthathaka, kubonakala ngathi kunika isisombululo phantse kuzo zonke iimfuno zokhathalelo lolusu. Enyanisweni, iye yaba ngumxholo odumileyo kangangokuba ngoku kuxoxwa kakhulu ngawo kwimidiya yoluntu. Kodwa yintoni eyenza esi sibane sibomvu sibonakala sinamandla onke sibe "sithandwa" esitsha sokhathalelo lolusu?

Yintoni isibane esibomvu?
Ukukhanya kuvela elangeni. Kodwa ilanga alingombala omnye nje kuphela. Linokwahlulwa libe yimibala esixhenxe yokukhanya esinokuyibona: obomvu, orenji, omthubi, oluhlaza, oluhlaza okwesibhakabhaka, oluhlaza okwesibhakabhaka kunye nowe-violet. Umahluko ukwimilinganiselo yazo yobude be-wavelength - okukhona ubude be-wavelength busiba bomvu ngakumbi; okukhona ubude be-wavelength busiba mfutshane, kokukhona umbala uba bomvu ngakumbi. Ukukhanya okubomvu kufumaneka kwisiphelo eside se-spectrum yokukhanya ebonakalayo, enoluhlu lwe-wavelength olumalunga ne-630nm-780nm. Olu lulwahlulo lwendalo kwi-spectrum ye-electromagnetic.
Ukukhanya okubomvu kunobude obude bobude bomphezulu. Oku kuthetha ukuba kungangena nzulu eluswini ngaphandle kokubangela ukurhawuzelelwa okukhulu kwizicubu zebhayoloji. UNjingalwazi uMichael Hamblin weSikolo sezonyango saseHarvard ufumanise ukuba ukukhanya okubomvu kungangena kwi-30mm nangaphezulu kwizicubu zomntu. Oku kwenza ukukhanya okubomvu kube lukhetho olufanelekileyo kunyango lobuhle, ukuvuselelwa, kwanamayeza.

Ukhathalelo lolusu olubomvu VS iindlela zemveli
Ngaphezu koko, ixabiso elikhethekileyo lokhathalelo lolusu olukhanyayo licaca ngakumbi xa lithelekiswa neendlela zemveli. Ukhathalelo lolusu lwendabuko lulandela kakhulu indlela 'yangaphandle', edla ngokubandakanya ukungenelela kwangaphandle 'ngezithako zeekhemikhali.'
Ukukhanya okuBomvu, ngokwako, luhlobo lwamandla omzimba. Akongezi ngqo naziphi na izinto eluswini, kodwa kunoko kuvuselela imvakalelo kunye namandla eeseli ngaphakathi, ngokudlulisela imiqondiso ethile yamandla kwiiseli. Le nkqubo yaziwa ngokuba yi-photobiological regulation.
Xa ukukhanya okubomvu kungena kwi-dermis, kujolisa ngqo kwi-mitochondria ngaphakathi kweeseli. Xa ifunxa amandla okukhanya, i-mitochondria iphucula kakhulu ukusebenza kakuhle kwe-ATP, ibangela uthotho lweempendulo ze-biochemical: ukukhawulezisa ukuveliswa kwe-collagen kunye ne-elastin, ukuphucula imetabolism yeeseli, ukukhawulezisa ukususwa kwee-free radicals kunye nenkunkuma, kunye nokulawula iimpendulo zokudumba. Ezi ziphumo zentsebenziswano zihlangene zifezekisa iingenelo ezininzi zokhathalelo lolusu, kubandakanya ukulwa nokwaluphala, ukulungiswa, ukulwa nokudumba, kunye nokukhanyisa, zonke ezi ziqinisekiswe zizifundo ezininzi zeklinikhi.

UMerican wayenguvulindlela ekunyamekeleni ulusu ngokukhanya okubomvu komzimba wonke.
IMerican ibisoloko ibandakanyeka kakhulu kwicandelo lezempilo nobuhle be-optical kangangeminyaka eli-17. Ngokusekelwe kuphando olunzulu malunga nokulawulwa kwamandla kunye ne-photobiological kokukhanya okubomvu, ifikelele kukhathalelo oludibeneyo lwe-phototherapy ebusweni nasemzimbeni ngokulawula ngokuchanekileyo ubude be-wavelength kunye nobukhulu bokuphuma kwamandla kokukhanya okubomvu, kudityaniswe noyilo lwe-ergonomic kunye nenkqubo yokulawula ukukhanya okukrelekrele, ukuze iingenelo zokhathalelo lolusu lokukhanya okubomvu zikwazi ukusasazeka ukusuka ebusweni ukuya emzimbeni.
Kuyafaneleka ukukhankanya ukuba ubugcisa bukaMerican budlula kude umthombo omnye wokukhanya. Ingadibanisa ngokwesayensi ubude bamaza okukhanya amaninzi, achanekileyo ukuze kufezekiswe iziphumo ezihambelanayo, ngaloo ndlela idale isisombululo sempilo nobuhle esisebenzayo nesibanzi 'esifanela bonke' kwiingxaki zolusu ezininzi.
Ukhathalelo lwesikhumba oluBomvu luvuselela amandla angaphakathi esikhumba ngamandla acocekileyo omzimba. Indalo yalo ekhuselekileyo, esebenzayo, kwaye ayingenisi ntsholongwane yenza ukuba lube lukhetho oluthembekileyo kubathandi bobuhle. IMerican yandisa iingenelo zokukhanya okubomvu kuwo wonke umzimba, ivula isahluko esitsha ekufuneni impilo nobuhle.
