Lokacin dangantaka da barci, Wakefulness, Hormones, da Metabolism
Rikicin Circadian na iya zama mafi mahimmancin ra'ayi don ganewa a duniya na maganin barci. Akwai harshe mai rikitarwa kuma yana dogara akan kimiyya wanda ba a iya kusantarwa ba. Abin farin ciki, ana iya samun fahimtar fahimtar kimiyya na rukunin circadian kuma yana iya taimakawa wajen bayyana wasu rashin barci , barci na rana , da kuma sauran barci.
Tsarin duniya
Tsarin duniya na 23 da 56 na kowane lokaci yana ba da tsinkaye na haske, yawan zafin jiki, abinci, da kuma aiki na predator. Ta hanyar juyin halitta da ta dace, musabbabin jikin mu - har ma da halayenmu an tsara su don amsa wannan lokacin daidai.
A shekara ta 1959, Franz Halberg ya fassara kalmar circadian, daga ma'anar Latin "game da rana." Ya bayyana kimanin kimanin awa 24 da aka tsara a kusan dukkanin kwayoyin halitta a duniya.
Na'urar gida
A cikin jikinmu, akwai tsarin da zai sanya matakan lokaci da aiki tare da matakai masu yawa cikin abubuwan da ke faruwa a cikin yanayi. Wasu daga cikin wadannan matakai masu muhimmanci sun hada da:
- Barci da wakefulness
- Metabolism
- Core jiki jiki
- Matakan Cortisol
- Matakan Melatonin
- Sauran hormones (girma hormone, thyroid hormone, da dai sauransu)
An tsara iko da waɗannan alamu a cikin tsarin kayan mu. Kayan aiki yana aiki tare da rhythms wanda zai ci gaba da kansa daga tasirin waje.
An gano nauyin halitta na farko, Clock , a shekara ta 1994. An gano wasu nau'in kwayoyin halitta da yawa wanda ya haifar da sauran kwayoyin halitta, kayan jiki, da kuma aiki na jikin.
Kowane tantanin halitta a cikin jikinmu yana biye da tsarin kwakwalwa, wani nau'i na halayen kwayoyin halitta wanda ya dace daidai da wadataccen albarkatu da kuma karamin ƙwayoyin sel a cikin baya na hypothalamus na kwakwalwa.
Ta hanyar hormones da sauransu kamar yadda duk da haka tasirin da ba a dame ba, mai kwakwalwa na tsakiya yana haɗaka ƙwayoyin da ke cikin kwayoyin halitta kamar bambancin zuciya, hanta, da kuma kyamara masu kamala.
Haske yana iya ganewa ta idanu kuma yana tafiya ta wurin tsinewa zuwa jijiyoyi na jiki. Sama da tsinkayyiyar ƙira, inda ƙuƙwalwar ƙwayoyi biyu suke biye bayan idanu, suna zaune a tsakiya (SCN). Wannan shine agogon agogo na jiki. Yana ma'aurata da yawancin tsarin tafiyar da ilimin lissafi wanda aka kwatanta da lokacin hasken da duhu a cikin yanayin.
Wadannan alamu zasu ci gaba ba tare da bayanan waje ba, amma zasu iya bambanta kadan daga tsawon rana. A sakamakon haka, a cikin keɓancewa daga sake sa ido, lokaci na waɗannan matakai zai iya zama sannu-sannu. Matsayin motsawa zai iya dogara ne akan shirin mu na kwayoyin, ko tau, tare da mafi yawancin mutane da kewayawa na ciki wanda ke gudana tsawon sa'o'i 24.
An fahimci cewa jinsin mu da kuma hulɗar da wasu abubuwan muhalli-musamman ma tasirin tasirin hasken rana - suna da tasiri masu mahimmanci akan sake saita zane na ciki. Wadannan tasirin na waje sune ake kira zeitgebers , daga Jamus don "masu ba da lokaci".
Ba tare da aiki ba
Lokacin da ake yin sauti na ciki cikin yanayin mu ko kuma aiki na zamantakewa, ƙwayar circadian kamar jinkirta da kuma ciwon kwanciyar hankali na lokacin barci zai iya faruwa.
Tare da cikakkiyar cirewa daga hasken haske, kamar yadda yake faruwa a cikin makanta duka, wani ɓangaren Ba-24 yana faruwa.
Wadannan yanayi suna hade da rashin barci da rashin barci da rana da kuma rashin daidaituwa a cikin barci mai barci wanda zai haifar dysfunction da zamantakewa. Abin farin ciki, maganin cututtukan circadian zai iya zama mai tasiri sosai kuma likita mai barci yana iya bada taimako da albarkatun taimako.
