Nizera ko umuntu wese ukora mubikorwa byo kumurika yamenye ubumenyi bwibanze bwubushyuhe bwamabara: ubushyuhe buke bwamabara butuma abantu bumva bamerewe neza kandi bishyushye, ubushyuhe bwamabara menshi burasobanutse kandi bushimishije, mubikorwa byo gushushanya nabyo bizakurikiza iki gitekerezo.

Nyamara, ubuzima nyabwo bwibidukikije byumucyo, ntabwo ari urumuri gusa, nta strobe, gusa twibanda kumurika, ubushyuhe bwamabara, uburinganire ntibihagije, dukeneye kandi kwitondera agaciro kangana na "ihwanye na pigiseli yijimye ihwanye" iri kumurongo hamwe nibisanzwe.

Nuburyo bwo gupima agaciro mbere yuko tumenya mbere igitekerezo cya "melatonin".

Melatonin

Mu myaka miriyari, urumuri rw'izuba rwabaye isoko yambere kandi yonyine yumucyo wagize injyana ya endogenous circadian injyana yubuzima bwose.

Impamvu abantu bazubahiriza "izuba rirashe kugirango bakore, izuba rirenze kuruhuka" umusaruro, amategeko yubuzima, kubera ko glande ya pinusi yubwonko bwumuntu izasohora imisemburo: melatonin, "ibinini bisanzwe byo kuryama", ni umubiri wacu bidatinze "ikimenyetso cyo kuruhuka".Ni "ibinini bisanzwe byo gusinzira", aribyo umubiri wacu "ikimenyetso cyo kuruhuka".Iyo umubiri ufite melatonine nyinshi, tuzasinzira;mugihe ibirimo melatonin ari bike, tuzaba dufite ingufu.

Kandi ingano ya melatonine isohoka ifitanye isano nuburemere bwurumuri.Kuberako hariho selile yigenga ya retinal ganglion selile (ipRGCs) muri retina yacu, ishobora guhuza poroteyine ya Photoreceptor, melanopsin, ikumva ubukana bwurumuri kandi ikohereza ibimenyetso mumyanya ya pineine, bityo bikagira ingaruka kumyunyu ngugu ya melatonine: byinshi mumwijima, bike muri urumuri rwinshi.kuri pineal gland, igira ingaruka kumyunyu ngugu ya melatonin: byinshi mumwijima na bike mumucyo mwinshi.Iyi niyo mpamvu byoroshye gusinzira mu mwijima.

Dufashe urugero rwa "amatara yubukorikori" - urumuri rwumuriro nkurugero, ubushyuhe bwamabara yari hafi 2000K, hamwe nurumuri ruto cyane rwubururu hamwe n itara ryinshi ritukura.Ubu bushyuhe buke bwamabara ashyushye, butuma abantu bumva bamerewe neza, birashobora kwinjira vuba mubitotsi.

Dufatiye kuri ibi, dushobora gusuzuma ingingo nyinshi:

a.Abantu bakeneye urumuri rutandukanye kubyo bakeneye bitandukanye;

b.Itara ryera rituma abantu bakanguka kandi bishimye, kandi urumuri rwumuhondo rutuma abantu baruhuka kandi neza;

c.Ikigaragara inyuma ni gusohora “ibinini bisanzwe byo kuryama” melatonin;

d.Itara ry'ubururu ritera "selile ya melatonin Photoreceptor selile" kandi ikabuza gusohora melatonin.

Izi nizo shingiro ryimiterere yumucyo wumuntu. 

Ibisobanuro n'ibipimo bya melatonin kumurika

Urwego rw'ihindagurika ry'ibinyabuzima rupimwa mu myaka ibihumbi magana, mu gihe amateka y’imico yabantu ari munsi yimyaka 10,000.Abantu bamenyereye imibereho igezweho mubijyanye na "software" ya psychologiya n'umuco, ariko "ibyuma" byimiterere ya physiologique ntabwo byajyanye nimpinduka."Isaha ya biologiya" mumibiri yacu nikintu "cyuma" kidashobora kugendana nimpinduka.Guhagarika isaha yibinyabuzima bigira ingaruka ku buryo butaziguye ibitotsi, ariko kandi biganisha ku myumvire mibi, itera umubyibuho ukabije, diyabete n'izindi ndwara ziterwa na metabolike.

Ariko ubu urashaka kugabanya itara ryijoro ntibishoboka, dukwiye gutekereza rero: ni ubuhe buryo bw'urumuri butazatera ikibazo cy’ibinyabuzima?

Twifuzaga gukora sisitemu yo kumurika yatanga imbaraga zihagije kumanywa kugirango dukomeze kuba maso, kandi itara rya nijoro ryahaza ibyifuzo bikenewe tutiriwe duhagarika ururenda rwa melatonin cyane kugirango tubangamire ireme ryibitotsi.

Kugirango ukore ibi, hakenewe ibipimo byo gupima ingano, bityo abahanga basobanuye iki giciro gishya cyo kumurika: EML (Equivalent Melanopic Lux), Melanopic Illuminance ihwanye, izwi kandi nka Retinotopic Equivalent Lux.bisobanura gupima fotometrike ikoreshwa mukugereranya urwego rwo gukangura fotokopi yumusaruro wumucyo kuri opsins yumukara.(Ibisobanuro byavuzwe mu Bipimo Byubaka Byiza)

Ibimurika bisanzwe (lx) bikoreshwa mugupima urumuri rwimikorere ya selile ya cone, mukigereranyo cyerekana urumuri rutuma ijisho ryumuntu ribona ibintu.

Ku rundi ruhande, melanopic illuminance (EML), ihindura ibintu bitera imbaraga z'umucyo mu kubipima bitewe nigisubizo cya ipRGCs kumurika nkuburyo bwo gusobanura mu buryo bwuzuye ingaruka zishingiye ku binyabuzima by’umucyo ku muntu nk'uburyo bwo gutanga inkunga kubitekerezo byiza bya circadian.

Umucyo hamwe na EML yo hejuru byongera kuba maso, kandi urumuri hamwe na EML yo hepfo itera ururenda rwa melatonine kandi bikagabanya kuba maso.Kubwibyo, uko waba ukora kose izuba rirashe cyangwa ukajya hanze kumanywa, ugomba guhitamo urumuri hamwe na EML ndende mugihe ukora kandi ukora, hanyuma ugahindura urumuri hamwe na EML nkeya mugihe uruhutse na mbere yo kuryama.

Inkomoko yatangajwe mbere kandi yemewe kubisobanuro byuzuye kuri EML nuburyo bwiza bwo kubaka.

Gupima urwego rwa melatonin rumurika

Nonese ko tuzi uruhare rwa EML namabwiriza abigenga, nigute dushobora kumenya agaciro nyako EML?

Hariho uburyo butatu bwo gukora ibi: ①gupima ukoresheje igikoresho gifotora; conversionguhindura igipimo cyoroshye;

Byaba ibipimo bya buri munsi, kwemerwa kwumushinga, cyangwa kwemeza abakiriya, abashushanya bakeneye gukoresha ibikoresho byumwuga bifotora kugirango bapime kandi bavugane namakuru.

Usibye ibipimo bine byingenzi byerekana urumuri, ubushyuhe bwamabara, itandukaniro rigaragara, hamwe nuburinganire, igikoresho cya fotometric cyongeyeho ibipimo bingana na melatonin illuminance, ibyo bikaba bihuye n’ibipimo mpuzamahanga byubuzima bwiza byubuzima bwiza ™ ibipimo by’ibidukikije, hamwe na ikosa ryo gupima rya <5%.

Uburyo bworoshye bwo kugereranya kugereranya bisobanura gupima cyangwa kubara indangagaciro zisanzwe "zisanzwe ziboneka kumurika" ukoresheje ibikoresho nka metero ya illuminance, software ya DIALux yigana, nibindi. Indangagaciro zimurika noneho zihinduka EML.Ibipimo bya lx na EML biratandukanye kumasoko atandukanye.

Kurugero, niba itara ryaka rimurikira umwanya kuri 200 lx, urumuri rwa melatonin muricyo gihe ni 200 x 0.54 = 108 EML.

Birumvikana, nubwo bifite urumuri rusa nubushyuhe busa, EML indangagaciro zigomba kuba zitandukanye niba gukwirakwiza ibintu bitandukanye.

Niba isoko runaka yumucyo itaboneka mumeza L1, nabihindura nte?Aha niho uburyo bwa kabiri bwo guhindura buza gukinishwa: guhinduranya neza.

Ububasha bugereranije kuri buri burebure bwabanje gupimwa hanyuma buremererwa hamwe na formula yihariye yo kubara igipimo nyacyo cya EML.

Kurugero, niba nshaka gukoresha itara rya BLV 4000K kumurika mucyumba cyanjye, nangahe nijoro?

Ukurikije inyubako ya WELL yuburiri: EML igomba kuba munsi ya 50 nijoro, hanyuma kumurika mucyumba bigomba kugenzurwa munsi ya 50 ÷ 0.87 = 58 lx muri simulation ya DIALux.

Ibyavuzwe haruguru ni "ihwanye na melatonin illuminance" ya kamere, inkomoko, gupima ibiyirimo, ndizera ko ufite imyumvire runaka yibintu byabantu bimurika, hanyuma bigashobora gukoreshwa mugushushanya iki gitekerezo.
