Kaya ndi chifukwa cha kuchita masewera olimbitsa thupi kapena mankhwala oipitsa omwe amapezeka m'zakudya ndi malo athu, tonsefe timavulala nthawi zonse. Chilichonse chomwe chingathandize kufulumizitsa njira yochiritsira thupi chingathandize kuti thupi lizipeza zinthu zofunika ndikulilola kuti liziyang'ana kwambiri pakukhala ndi thanzi labwino osati kuchira kokha.
Dr. Harry Whelan, pulofesa wa matenda a ubongo wa ana komanso mkulu wa mankhwala oopsa ku Medical College of Wisconsin wakhala akufufuza za kuwala kofiira m'maselo ndi pa anthu kwa zaka zambiri. Ntchito yake mu labotale yasonyeza kuti maselo a khungu ndi minofu omwe amakula m'maselo ndikuwonetsedwa ku kuwala kwa LED infrared amakula mofulumira 150-200% kuposa mitundu yolamulira yomwe siilimbikitsidwa ndi kuwalako.
Pogwira ntchito ndi madokotala a panyanja ku Norfolk, Virginia ndi San Diego ku California pochiza asilikali omwe adavulala pa maphunziro, Dr. Whelan ndi gulu lake adapeza kuti asilikali omwe adavulala pa maphunziro omwe adathandizidwa ndi ma diode otulutsa kuwala adakula ndi 40%.
Mu 2000, Dr. Whelan anamaliza ndi kuti, "Kuwala kwapafupi ndi infrared komwe kumatulutsidwa ndi ma LED awa kumawoneka ngati kwabwino kwambiri pakuwonjezera mphamvu mkati mwa maselo. Izi zikutanthauza kuti kaya muli pa Dziko Lapansi kuchipatala, mukugwira ntchito m'sitima yamadzi pansi pa nyanja kapena mukupita ku Mars mkati mwa chombo cha m'mlengalenga, ma LED amawonjezera mphamvu ku maselo ndikufulumizitsa kuchira."
Pali maphunziro ena ambiri omwe akuwonetsa iziubwino wamphamvu wa kuwala kofiira pochiritsa mabala.
Mwachitsanzo, mu 2014, gulu la asayansi ochokera ku mayunivesite atatu ku Brazil linachita kafukufuku wasayansi wa zotsatira za kuwala kofiira pa kuchira kwa mabala. Pambuyo pophunzira maphunziro okwana 68, ambiri mwa iwo omwe adachitika pa nyama pogwiritsa ntchito kutalika kwa mafunde kuyambira 632.8 ndi 830 nm, kafukufukuyu adatsimikiza kuti "... phototherapy, kaya ndi LASER kapena LED, ndi njira yothandiza yochiritsira mabala a pakhungu."
