Chiedza chebhuruu chinoburitswa nenhare mbozha, makomputa, e-reader, materevhizheni uye kunyange mwenje yemumaguta emaguta mazhinji. Neichi chikonzero, ruzhinji rwevanhu rwunoratidzirwa kwariri zuva nezuva.
Zvakawanda zvechiedza chakagadzirwa zvinogona kuva nemhedzisiro inokanganisa pazvinhu zvakawanda zvehutano hwevanhu, kunyanya husiku. Zvakanyanya izvo dzimwe nyanzvi hadzizeze kuinongedzera sedambudziko riri kukura rehutano hweveruzhinji.
Chiedza ndiyo inonyanya kukosha synchronizer yevanhu circadian mutinhimira. Masero ari mu retina anopindura kune pfupi-wavelength mwenje, iyo inouya kubva kune isina makore bhuruu denga, asi zvakare kubva kune bhuruu mwenje. Sezvo mwenje yechiedza ichirova aya maseru, uropi hunomira kuburitsa melatonin kutarisa mahormone senge cortisol uye ghrelin, izvo zvinotimutsa nekutipa nzara.
Pane humbowo hunoratidza kuti kuratidzwa nechiedza chebhuruu hakungokonzere matambudziko ekurara chete, asi zvakare kuwedzera uremu, kushushikana, chirwere chemwoyo, uye gomarara. Parizvino chikonzero uye hukama hwehukama hauna kusimbiswa, asi kune nyanzvi zhinji, pane data rinotyisa zvakakwana kuti uwane chiito nekukurumidza.
Kana iwe uchida kudzivirira kukanganisa kunokonzerwa nechiedza chebhuruu, ita sepaInternational Space Station, kwavanosviba uye kutamisa mwenje kuenda kurefu wavelength sehusiku hunodonha. Funga kudzimisa mwenje uye kutsika kubva kune yakajeka bhuruu skrini usiku. Shandisa mafirita emagetsi ebhuruu pamagalasi ako kana uanyore zvakananga pamagetsi emagetsi senge mafoni nemapiritsi. Iwe unogona zvakare kuchinja ekuratidza marongero kumatoni anodziya. Kutsiva mwenje wekurara nemwenje mirefu yewavelength, uye kuisa mari mumasikiti ekurara kana mwenje yemumugwagwa ichivheneka pahwindo rako iriwo mamwe emazano anonyanya kushandiswa
