Chithandizo cha kuwala kofiira chikufalikira padziko lonse lapansi. Kuyambira zipangizo zapakhomo mpaka zipatala zaukadaulo, kuyambira mankhwala oletsa ukalamba ndi ziphuphu mpaka kukonza khungu lofewa, chimapezeka m'mayankho a zosowa zonse za chisamaliro cha khungu ndipo chakhala nkhani yotchuka kwambiri pa malo ochezera a pa Intaneti. Koma n'chiyani chimapangitsa kuwala kofiira kumeneku kukhala njira yatsopano yodziwika bwino yosamalira khungu?
Kuwala kumachokera ku dzuwa. Kuwala kwa dzuwa si mtundu umodzi, koma kungagawidwe m'mitundu isanu ndi iwiri yooneka: yofiira, yalanje, yachikasu, yobiriwira, yabuluu, ya indigo, ndi ya violet. Kusiyana kwawo kuli m'mafunde awo—kutalika kwa mafunde, mtunduwo umakhala wofiira kwambiri; kutalika kwa mafunde kumakhala kochepa, komwe kumaonekera kwambiri ngati utoto.Kuwala kofiira kuli kumapeto kwa mafunde aatali a kuwala kooneka, ndipo kutalika kwa mafunde ake kuli pakati pa 630nm-780nm.Iyi ndi gawo la ma frequency lomwe lilipo bwino mkati mwa electromagnetic spectrum.
Chifukwa cha makhalidwe ake a "long-wave", kuwala kofiira kumakhala ndi mphamvu yolowera mkati komanso mphamvu yokhazikika, zomwe zimapangitsa kuti kulowe mosavuta pamwamba pa khungu ndikufikira minofu yapansi panthaka popanda kuyambitsa kuyabwa kwakukulu ku minofu ya zamoyo. Kafukufuku wofanana ndi Pulofesa Michael Hamblin wa ku Harvard Medical School watsimikizira kuti kuwala kofiira kumatha kulowa m'thupi la munthu mpaka kupitirira 30mm. Khalidweli limapatsa kuwala kofiira mwayi wachilengedwe wogwiritsidwa ntchito pokongoletsa, kukonzanso, komanso ngakhale kuchipatala.
Kuphatikiza apo, phindu lapadera la chithandizo cha kuwala kofiira pa chisamaliro cha khungu limakhala lomveka bwino poyerekeza ndi njira zachikhalidwe.Kusamalira khungu mwachikhalidwe kumatsatira njira ya "kunja-mkati", makamaka kumagwiritsa ntchito mankhwala ochokera kunja.
Mosiyana ndi zimenezi, kuwala kofiira ndi mtundu wa mphamvu zakuthupi. Sikuwonjezera zinthu zina pakhungu mwachindunji, koma m'malo mwake kumayatsa ntchito za maselo ndi mphamvu zawo kuchokera mkati mwawo mwa kutumiza zizindikiro zinazake za mphamvu ku maselo. Njira imeneyi imatchedwa photobiomodulation.
Kuwala kofiira kukalowa mu dermis, kumalunjika bwino ku mitochondria mkati mwa maselo. Mukatenga mphamvu ya kuwala, mitochondria imawonjezera kwambiri mphamvu ya kapangidwe ka ATP, zomwe zimayambitsa machitidwe osiyanasiyana a biochemical: kufulumizitsa kupanga kolajeni ndi elastin, kukulitsa kagayidwe ka maselo, kufulumizitsa kuchotsa ma free radicals ndi zinyalala, komanso kuwongolera mayankho otupa. Zotsatirazi zogwirizana pamodzi zimapereka maubwino ambiri osamalira khungu, kuphatikiza kuletsa ukalamba, kukonza, zotsatira zoletsa kutupa, ndi kuwunikira khungu, zonse zomwe zatsimikiziridwa ndi maphunziro ambiri azachipatala.
Merican yakhala ikugwira ntchito mwakhama pa thanzi la maso ndi kukongola kwa zaka 17. Kutengera kafukufuku wozama pa mphamvu ya kuwala kofiira ndi zotsatira zake pa zithunzi, komanso kudzera mu kuwongolera molondola kutalika kwa kuwala kofiira ndi mphamvu yotulutsa mphamvu, kuphatikiza kapangidwe ka ergonomic ndi machitidwe anzeru owongolera kuwala, Merican yakhala ikutsogolera njira yophatikizira phototherapy pankhope ndi thupi, kukulitsa ubwino wa chisamaliro cha khungu la kuwala kofiira kuyambira pankhope mpaka thupi lonse.
Ndikofunikira kudziwa kuti luso la Merican silimangopereka kuwala kokha; limatha kuphatikiza mwasayansi mafunde angapo olondola a kuwala kuti likwaniritse zotsatira zogwirizana, motero limapanga njira zabwino kwambiri komanso zodziwika bwino za thanzi la maso ndi kukongola kwa mavuto a khungu osiyanasiyana.
Chithandizo cha kuwala kofiira chimabwezeretsa mphamvu yamkati ya khungu pogwiritsa ntchito mphamvu yeniyeni yakuthupi. Chikhalidwe chake chotetezeka, chogwira ntchito, komanso chosawononga chimapangitsa kuti chikhale chisankho chodalirika kwa okonda kukongola ambiri. Mericon imawonjezera ubwino wa chithandizo cha kuwala kofiira ku thupi lonse, ndikutsegula gawo latsopano pakufunafuna thanzi ndi kukongola.
