Twese tuzi ko kwishyira kure cyane ku rumuri rwa ultraviolet bishobora gutera ubushyuhe bw'izuba, kandi ko urumuri rutukura rushobora gukemura ibibazo by'uruhu. Ariko se wari uzi ko izi zuba ebyiri zisa n'izihanganye zishobora gukorana kugira ngo zitange umusaruro mwiza kurushaho?
Mu nyandiko ye yise “Gukoresha urumuri rw'izuba kugira ngo ubuzima bukomeze kubaho,” umuhanga mu binyabuzima w'umunyamerika Dr. Ray Peat agaragaza ko urumuri rw'imirasire ya ultraviolet atari ikintu kibi gusa, ahubwo ko ari “umuti karemano” ukomeye, ingaruka nziza zawo zishingiye ku gipimo gikwiye n'ikoreshwa ryawo. Urugero, kuwuvanga n'urumuri rutukura bishobora kuringaniza ibyiza byawo, bigatuma ubuvuzi butekanye kandi bukagira ingaruka nziza, mu gihe bigabanya cyane ibyago bishobora kubaho.
01. Ibyiza byihishe byo kwibasirwa n'imirasire iri ku rugero
Mu bushakashatsi bwa Dr. Ray Peat, impamvu nyamukuru ituma urumuri rwa ultraviolet rwitwa "umuti karemano" ni uko rukora nk'"umuti utuma umubiri ukora Vitamine D.
Byongeye kandi, kwishyira ku rumuri rw'imirasire ya ultraviolet (UV) mu rugero ruciriritse bishobora gutuma uruhu rukora melanin, bigatuma rugira isura ishaje cyane cyangwa ishaje. Ifite kandi ubushobozi bwiza bwo kurwanya antioxydants, ikuraho uturemangingo tw’ingufu, igabanya ihinduka ry’ibara ry’uruhu, kandi ikagabanya ibyago byo kugira ibibazo by’uruhu biterwa no guhangayika kw’uruhu.
Bityo, ingaruka zo gushya kw'uruhu ziterwa no kwigaragaza mu buryo buri hagati y'imirasire ya UV yongera imiterere y'uruhu ndetse n'ubushobozi bwo kurinda icyarimwe.
02. Ni gute urumuri rutukura "ruhuza" n'urumuri rwa ultraviolet?
Ashingiye ku gusobanukirwa byimbitse ibyiza by'urumuri rwa ultraviolet, Dr. Ray Peat yanatanze igitekerezo: “Urumuri rutukura rwinjira mu kirere rushobora kuba ari cyo kintu cy’ingenzi cyane kirwanya stress ku binyabuzima byose.” Ibi bivuze ko urumuri rutukura rufite ingaruka zo kurwanya imirasire; si intungamubiri z’ingirakamaro ku bantu gusa ahubwo rushobora no kongera ubuzima bw’ibinyabuzima byose ku Isi, harimo n’ibimera.
Iyo usuzumye ubushakashatsi bwa siyansi n'ubuvuzi burenga 50.000 ku buvuzi bw'urumuri rutukura bwakozwe kugeza ubu, uzasanga ko uko umuntu yaba ameze kose, ashobora kungukirwa cyane n'urumuri rutukura n'urumuri rurerure.
Ubushakashatsi bwinshi bwemewe bwagaragaje ko urumuri rutukura rugira ingaruka zo kurinda uruhu rw'umuntu. Urumuri rutukura rushobora kugabanya kwangirika guterwa n'imirasire ya ultraviolet (UV) ku ruhu, kubuza apoptosis iterwa na UV, kunoza ubwiyongere bw'izuba buterwa no kwiyongerera ubwiyongere bw'izuba, kugabanya iminkanyari n'iminkanyari, no kugabanya ubukana bw'uruhu.
Ibi bigaragaza ko guhuza uburyo bwo kuvura urumuri rutukura n’uburyo bugezweho bwo kuvura urumuri rutukura, binyuze mu gusimbuza hafi 50% by’amatara ya ultraviolet n’amatara atukura, bishobora kubungabunga agaciro k’urumuri rutukura mu kuvura cyangwa gukora neza mu gihe bigabanya ibyago bishobora guterwa narwo binyuze mu buryo bwo kurinda urumuri rutukura, bigatuma uburyo bwo kuvura urumuri rutukura burushaho kuba bwiza kandi bunoze.
03. Gahunda yo Guteka Ibara ry'Umutuku mu Buryo Bwiza muri Amerika
Nk’umuntu watangije ishami ry’ubuzima bw’amaso n’ubwiza, Merican ihuza cyane na filozofiya y’ubushakashatsi ya Dr. Ray Petz, kandi ku bufatanye n’itsinda ry’ubushakashatsi n’iterambere ry’Abadage rya Cosmedico, yagize uruhare mu iterambere ry’ikoranabuhanga rya RUBINO mu gusiga irangi ry’urumuri rutukura, bituma habaho igisubizo cyiza kandi cyiza cyo gusiga irangi ry’urumuri ku isi yose.
Ikoranabuhanga rya RUBINO ryo gusiga ibara ry’urumuri rutukura ntabwo ari uruvange rw’amasoko abiri y’urumuri gusa, ahubwo rigera ku buringanire butunganye bw’urumuri rwa ultraviolet n’urumuri rutukura binyuze mu kugenzura neza no gupima ingano ya siyansi. Ryongera neza ibara ry’urumuri ku kigero cya 50%, bigatuma ibara ry’umuringa ringana, riramba kandi rigaragara nk’iry’umuhondo.
Ku ruhande rumwe, binyuze mu kugenzura igice runaka cy'uburebure bw'urumuri rwa UV, ikoranabuhanga rituma uruhu rukora neza, rigatuma habaho ikorwa rya melanin; ku rundi ruhande, gukoresha ikoranabuhanga ry'urumuri rutukura bikora ku bice byimbitse by'uruhu, bigatera imbaraga collagen na elastin, bigatera imbaraga ingano ya vitamine D, kandi bigagabanya kwangirika kwa radicals, bityo bigatuma uruhu rukomeza gukora neza no koroha nyuma yo gushya.
Ni ngombwa kuvuga ko ikoranabuhanga rya RUBINO red light tanning ari ikoranabuhanga ry’ingenzi ryakozwe na Merican n’ikipe y’Abadage ya Cosmedico ku isi. Ku isoko ry’imbere mu gihugu, ni irya Merican gusa kandi ni iry’umwihariko, bigatuma ibindi bigo bidashoboka ko byiyongera.
Uruvange rw’ubuhanga rwa UV ruciriritse n’urumuri rutukura rugera ku nyungu ebyiri zo gusiga ibara ry’uruhu no kuvugurura uruhu, bitanga inyungu zitangaje. Ikoranabuhanga rya Merican RUBINO ryo gusiga ibara ry’uruhu ritukura rigaragaza neza icyerekezo gishya cy’iterambere ry’ikoranabuhanga rya UV phototherapy mu gihe kizaza.
