Haraheze imyaka irenga icumi, abantu benshi ntibari gutekereza ko kumurika nubuzima bifitanye isano. Nyuma yimyaka irenga icumi yiterambere ,.Itarainganda ziyongereye kuva mu gukurikirana imikorere yumucyo, kuzigama ingufu nigiciro kugeza kubisabwa kugirango ubuziranenge bwumucyo, ubuzima bworoheje, ibinyabuzima byoroheje n’ibidukikije. By'umwihariko mu myaka yashize, ibibazo byangiza urumuri rwubururu, ihungabana ryabantu ndetse no kwangirika kwabantu kwatewe na LED bigenda bigaragara cyane, bigatuma inganda zimenya ko kumenyekanisha amatara meza byihutirwa.

Urufatiro rwibinyabuzima rwo kumurika ubuzima

Muri rusange, amatara yubuzima nugutezimbere no kunoza imikorere yabantu, imyigire yabo nubuzima bwabo hamwe nubuziranenge binyuze mumuri LED, kugirango biteze imbere ubuzima bwimitekerereze numubiri.

Ingaruka zishingiye ku binyabuzima zumucyo kubantu zirashobora kugabanywamo ingaruka ziboneka ningaruka zitagaragara.

(1) Ingaruka zigaragara z'umucyo:

Umucyo ugaragara unyura muri cornea yijisho kandi ushushanywa kuri retina unyuze mumurongo. Yahinduwe mubimenyetso bya physiologique na selile ya Photoreceptor. Nyuma yo kuyakira, nervice optique itanga icyerekezo, kugirango tumenye ibara, imiterere nintera yibintu mumwanya. Iyerekwa rishobora kandi gutera abantu imitekerereze yimitekerereze, ningaruka zo mumitekerereze.

Hariho ubwoko bubiri bwingirabuzimafatizo: imwe ni selile ya cone, yumva urumuri nibara; Ubwoko bwa kabiri ni selile zimeze nkinkoni, zishobora kumva urumuri gusa, ariko ibyiyumvo byikubye inshuro 10000 iyambere.

Ibintu byinshi mubuzima bwa buri munsi ni ingaruka zigaragara zumucyo:

Icyumba cyo kuraramo, icyumba cyo kuriramo, iduka rya kawa, urumuri rushyushye rwamabara (nkumuhondo nijimye yijimye) bituma umwanya wose ugira ikirere gishyushye kandi kiruhutse, kandi bigatuma uruhu rwabantu no mumaso bisa neza mugihe kimwe.

Mu mpeshyi, itara ry'ubururu n'icyatsi bizatuma abantu bumva bakonje; Mu gihe c'itumba, umutuku utuma abantu bumva basusurutse.

Amatara akomeye yamabara arashobora gutuma ikirere gikora kandi kigaragara, kandi cyongera ibihe byiminsi mikuru.

Ibyumba byumuryango bigezweho kandi bikunze gukoresha amatara atukura nicyatsi kugirango ataka icyumba na resitora kugirango yongere umwuka mwiza.

Restaurants zimwe ntizifite amatara muri rusange cyangwa amatara kumeza. Bakoresha gusa gucana buji kugira ngo bahagarike ikirere.

(2) Ingaruka zitagaragara zumucyo, kuvumbura iprgc:

Hariho ubwoko bwa gatatu bwingirabuzimafatizo zifata retina yumuntu - insimburangingo ya fotosensitif retinal ganglion selile, ishinzwe kugenzura ingaruka zitagaragara hanze yicyerekezo cyumubiri, nkumurimo wo gucunga igihe, guhuza no kugenzura ibikorwa byabantu injyana na amplitude muburyo butandukanye ibihe.

Izi ngaruka zitagaragara kandi zitwa sichen visual effect, yavumbuwe na Berson, Dunn na Takao bo muri kaminuza ya Brown mu nyamaswa z’inyamabere mu 2002. Ni imwe mu icumi zavumbuwe ku isi mu 2002.

Ubushakashatsi bwerekanye ko ingaruka zitagaragara z’imbeba zo mu rugo ari 465nm, ariko ku bantu, ubushakashatsi bwerekeranye n’irondakoko bugaragaza ko bugomba kuba 480 ~ 485nm (impinga y’utugingo ngengabuzima na selile ni 555nm na 507nm).

(3) Ihame rya iprgc igenzura isaha yibinyabuzima:

Iprgc ifite imiyoboro yayo yohereza ubwonko mu bwonko bwabantu, itandukanye cyane numuyoboro wogukwirakwiza. Nyuma yo kwakira urumuri, iprgc itanga ibimenyetso bya bioelectric, byanduza hypothalamus (RHT), hanyuma ikinjira muri nucleus ya suprachiasmatic (SCN) hamwe na nucleus nucleaux (PVN) kugirango igere kuri glande.

Indwara ya pineal ni ihuriro ryisaha yibinyabuzima byubwonko. Isohora melatonin. Melatonin ikomatanyirizwa kandi ikabikwa muri gineine. Ibyishimo bya simpatique byinjiza ingirabuzimafatizo kugirango irekure melatonine mumaraso atemba kandi itera ibitotsi bisanzwe. Kubwibyo, ni imisemburo yingenzi igenga injyana ya physiologique.

Ururenda rwa melatonin rufite injyana igaragara ya circadian, ibuzwa kumanywa kandi ikora nijoro. Nyamara, gushimisha imitsi yimpuhwe bifitanye isano rya bugufi ningufu namabara yumucyo bigera kuri gineine. Ibara ryoroheje nuburemere bwumucyo bizagira ingaruka kumasohoro no kurekura melatonine.

Usibye kugenzura isaha yibinyabuzima, iprgc igira ingaruka kumutima wumuntu, umuvuduko wamaraso, kuba maso hamwe nubuzima, ibyo byose bikaba ari ingaruka zitagaragara zumucyo. Byongeye kandi, ibyangiritse byumubiri biterwa numucyo nabyo bigomba guterwa ningaruka zitagaragara zumucyo.
