Vuba aha, itsinda ry’ubushakashatsi ryaturutse muri kaminuza ya Exeter mu Bwongereza ryasanze mu bice byinshi by’Uburayi, ubwoko bushya bw’umwanda w’umucyo bwarushijeho kugaragara hamwe n’ikoreshwa ryinshi.LED yo kumurika hanze. Mu mpapuro zabo zasohotse mu kinyamakuru Progress in Science, itsinda ryasobanuye ubushakashatsi bwabo ku mafoto yakuwe kuri sitasiyo mpuzamahanga.

Ubushakashatsi bwibanze bwerekanye ko urumuri rw’ibinyabuzima mu bidukikije rushobora kugira ingaruka mbi ku nyamaswa n’abantu. Kurugero, ubushakashatsi bwerekanye ko inyamaswa n’abantu bahura n’ikibazo cyo gusinzira, kandi inyamaswa nyinshi zayobewe n’umucyo nijoro, biganisha ku bibazo byinshi byo kubaho.

Muri ubu bushakashatsi bushya, abayobozi baturutse mu bihugu byinshi bagiye baharanira ko hakoreshwaItaramumihanda na parikingi, aho gucana amatara ya sodium gakondo. Mu rwego rwo kurushaho gusobanukirwa n’ingaruka z’iri hinduka, abashakashatsi babonye amafoto yafashwe n’ibyogajuru kuri sitasiyo mpuzamahanga y’ikirere kuva 2012 kugeza 2013 na 2014 kugeza 2020. Aya mafoto atanga urugero rwiza rw’umurambararo w’umucyo kuruta amashusho ya satelite.

Binyuze ku mafoto, abashakashatsi barashobora kubona uturere two mu Burayi twahinduyeLED itarakandi ku rugero runini, amatara ya LED yahinduwe. Basanze ibihugu nk'Ubwongereza, Ubutaliyani, na Irilande byagize impinduka zikomeye, mu gihe ibindi bihugu nka Otirishiya, Ubudage, n'Ububiligi bitigeze bihinduka. Bitewe n'uburebure butandukanye bw'urumuri rutangwa na LED ugereranije n'amatara ya sodium, kwiyongera k'umucyo w'ubururu birashobora kugaragara neza ahantu hahinduwe amatara ya LED.

Abashakashatsi bagaragaza ko basanze urumuri rw'ubururu rushobora kubangamira umusaruro wa melatonine mu bantu no ku yandi matungo, bityo bikabangamira ibitotsi. Kubwibyo, kwiyongera kwurumuri rwubururu ahantu hacana amatara ya LED bishobora kugira ingaruka mbi kubidukikije ndetse nabantu batuye kandi bakorera muri utwo turere. Basaba ko abayobozi bagomba kwiga bitonze ingaruka zamatara ya LED mbere yo guteza imbere imishinga mishya.
