Chii chinonzi circadian kutenderera
Zvemukati
Muviri wemunhu unodzorwa neyakaitika wachi yemukati mune ayo ezuva nezuva zviitwa, sezvazvinoitika nekudya nguva uye kumuka uye nguva dzekurara. Maitiro aya anodaidzwa kunzi circadian cycle kana circadian rhythm, iyo ine simba rakakura pakugaya, kugadziridza kwesero uye kudzora tembiricha yemuviri.
Munhu wega wega ane wachi yake yemukati uye nekudaro vanhu vakaiswa muvanhu vemangwanani, ndivo vanova vanomuka nekukurumidza uye vanomuka mangwanani, vanhu vemasikati, ndivo vanova vanononoka kumuka nekunonoka kurara, uye varevereri.
Physiology yemunhu circadian kutenderera
Iyo circadian mutinhimira inomiririra iyo nguva yemaawa makumi maviri nemana umo zviitiko zvemuzvarirwo wemunhu zvapedziswa uye umo kurara uye kudya kunodzorwa. Nguva yekurara inotora angangoita maawa masere uye iyo nguva yekumuka inotora angangoita maawa gumi nematanhatu.
Pakati pezuva, kunyanya nekuda kwesimba rechiedza, cortisol inogadzirwa, iyo inosunungurwa neadrenal gland uye iyi hormone inowanzo kudzika husiku panguva yekurara uye inowedzera mangwanani, kuwedzera kumuka masikati. Iyi hormone inogona zvakare kuwedzera munguva dzekushushikana kana kuve yakakwira mune isingagumi mamiriro, ayo anogona kukanganisa kushanda kwakakodzera kweiyo circadian kutenderera. Ona kuti iyo hormone cortisol ndeyei.
Manheru, kugadzirwa kwecortisol kunoderera uye kunowedzera kugadzirwa kwemelatonin, iyo inobatsira kukonzeresa kurara, kurega kugadzirwa mangwanani. Neichi chikonzero, vamwe vanhu vane chinetso chekurara, vanowanzo tora melatonin manheru, kubatsira kubatsira kurara.
Kukanganisika kweruzhowa mutinhimira
Iyo circadian kutenderera inogona kuchinjwa mune mamwe mamiriro, ayo anogona kukonzeresa kukanganiswa kwekurara uye kukonzera zviratidzo zvakadai sekurara zvakanyanya masikati uye kushaya hope usiku, kana kutokonzeresa zvakakomba matambudziko ehutano. Ziva kusagadzikana kweiyo circadian kutenderera.
