Uruhu ruri
Uruhu, nkumubiri wacu wose (kandi nkibinyabuzima byose), bifite isaha yimbere. Injyana ya buri munsi yabaye ingingo yo kwiga mu kinyejana cya XVIILI, ubwo umuhanga mu bya siyansi w'Ubufaransa Jean-Jacques d'GORANG yasobanuye bwa mbere ko amababi y'ibimera akomeje kugenda mu masaha 24 afata hafi amasaha 24 . Injyana nk'iyi yitwaga hamwe n'abarindwi (kuva Lata. Circa - hafi no gupfa - hashyizweho imyaka), yashizweho kumyaka miriyoni kandi ifitanye isano nimpinduka za buri munsi kumanywa nijoro. Amasaha y'ibinyabuzima aherereye mu mashami menshi yo mu bwonko kandi agizwe na genes zitandukanye zigenga inzira z'umubiri z'umubiri wose, harimo no kuvugurura ingirabuzimafatizo z'uruhu.
"Kurenga kuri Giriyoni Kamere biganisha ku ngaruka mbi ku buzima, isura n'imibereho myiza, ivuga ko Vermotokostologue Veronika Antosik. - Umubiri ufite sisitemu yimbere yemerera guhuzwa no guhanura impinduka zijyanye nigihe gihinduka cyumunsi, ariko birashobora kuvunika byoroshye.

Itandukaniro hagati y'injyana y'ibinyabuzima by'urubanza rwose ruganisha ku guhangayikishwa na chardian ikorera iterambere ryindwara nyinshi nigihe cyo gusaza imburagihe. "
Ubuzima ku isaha
Uruhu rwasubiwemo nijoro kandi rugarura, kandi bibaho mugihe runaka. Niba umuntu yanze ibitotsi nijoro cyangwa aguye hejuru ya saa sita z'ijoro, imisembuzi ya cortisol ikorwa mu mubiri usenya selile. Kandi, uko binyuranye, hamwe no kugenda mugihe cyo gusinzira no kubona, selile irakenewe × 7-8 amasaha yo gusinzira bitanga imisemburo, itezimbere imiterere yuruhu, kuvugurura. Ukurikije impuguke, hafi hafi nijoro (zatanzwe
Ibyo wagiye kuryama kugeza 23.00) selile zitangira gusangira cyane cyane, aho iki gihe cyiswe "isaha yumuzahabu".
Mu mpinga y'ibikorwa byo kuvugurura selile no kongera ikwirakwizwa rya vascular (ni ukuvuga kuva 11 kugeza saa yine za mugitondo), urwego rwo hejuru rwo kwinjira mu ruhu rw'ibintu byingenzi bivugwa. Kubwibyo, amavuta yose hamwe nibicuruzwa byita ku ruhu bishyirwa mu gice cy'isaha imwe yo kuryama.
Guhuza by'agateganyo urugero rufite aho bihaza "Zhavorkov" - abagwa kare barazamuka hakiri kare. Ariko nyuma "ba nyir'igitumo" ibinyoma kandi basinziriye igihe kirekire, ugomba gusubiramo gahunda yawe niba ushaka kugaragara nkibyayo kandi bishya.
Nijoro
