Kuwala kwa kuwala kwakhalapo kuyambira kalekale pamene zomera ndi zinyama zakhala padziko lapansi, popeza tonsefe timapindula pang'ono ndi kuwala kwa dzuwa.
Sikuti kuwala kwa UVB kochokera kudzuwa kumalumikizana ndi mafuta a kolesterolini pakhungu kuti athandizire kupanga vitamini D3 (potero kukhala ndi phindu la thupi lonse), komanso mbali yofiyira ya kuwala kowoneka bwino (600 - 1000nm) imalumikizananso ndi enzyme yofunika kwambiri. m'maselo athu a mitochondria, kukweza chivindikiro pa mphamvu zathu zopangira mphamvu.
Thandizo lamakono lamakono lakhalapo kuyambira kumapeto kwa zaka za m'ma 1800, pasanapite nthawi yaitali magetsi ndi kuunikira kunyumba kunakhala chinthu, pamene Faroe Islands anabadwa Niels Ryberg Finsen anayesa kuwala monga mankhwala a matenda.
Pambuyo pake Finsen adapambana mphoto ya Nobel yamankhwala mu 1903, chaka chimodzi asanamwalire, pokhala wopambana kwambiri pochiza nthomba, lupus ndi matenda ena a khungu ndi kuwala kokhazikika.
Thandizo lowala koyambirira limaphatikizapo kugwiritsa ntchito mababu achikhalidwe, ndipo maphunziro opitilira 10,000 adachitika pakuwala mzaka za zana la 20.Maphunziro amachokera ku zotsatira za nyongolotsi, kapena mbalame, amayi apakati, akavalo ndi tizilombo, mabakiteriya, zomera ndi zina zambiri.Chitukuko chaposachedwa chinali kuyambitsa zida za LED ndi ma laser.
Pamene mitundu yambiri idayamba kupezeka ngati ma LED, komanso luso laukadaulo lidayamba kuyenda bwino, ma LED adakhala chisankho chomveka bwino komanso chothandiza pazamankhwala opepuka, ndipo ndi muyezo wamakampani masiku ano, ndikuwongolera bwino.
