Vagus Nerve Imathandizira Matumbo, Wits, ndi Chisomo Chopanikizika

Zamkati

• Kulumikizana kwa Vagus-Brain Kungathe Kuchepetsa "Kulimbana, Kuuluka, kapena Kuyimitsa" Mayankho a Kupanikizika
• Kuda Nkhawa Kuwerenga
• Kuda nkhawa kwa COVID-19 ndikusintha kwaubwenzi

Matenda a nkhawa asanduka mliri wadziko lonse. Mu Januwale 2017, APA idasindikiza lipoti lawo la "Stress in America: Coping With Change" lomwe limafotokoza zakukwera koyamba kwamisala ku United States kuyambira pomwe kafukufukuyu adayamba zaka khumi zapitazo. Ripotilo lidapezanso kuti magawo awiri mwa atatu mwa omwe amafunsidwa nthawi zonse amakhala opsinjika pamoyo wawo watsiku ndi tsiku komanso kuti "kusatsimikiza zamtsogolo" kudali kovutitsa anthu ambiri.

Pamzere womwewu, pa Okutobala 15, 2017, Magazini ya New York Times inafalitsa nkhani yakuti, “Chifukwa Chiyani Achinyamata Ambiri Akuvutikabe ndi Kuda Nkhawa? ”Mawu am'mutu wa nkhaniyi akuti:" Makolo, akatswiri azachipatala, komanso masukulu akuvutika kudziwa ngati kuthandiza achinyamata omwe ali ndi nkhawa kumatanthauza kuwateteza kapena kuwakakamiza kuti athane ndi mantha awo. " . ”

Pazaka khumi zapitazi, kuda nkhawa kwadutsa kukhumudwa chifukwa chomwe chimapangitsa ophunzira aku koleji kuti apeze upangiri wamaganizidwe. Zaposachedwa Nthawi nkhaniyo inati “ Kuwonjezeka kwangozi ndi kudziona kuti sitingathe kupirira , ”Ndikutanthauzira kofala kwa nkhawa yomwe imamveka nthawi zambiri kuchipatala chopanda phindu, chogona cha Mountain Valley ku New Hampshire kwa anyamata ndi atsikana omwe ali ndi vuto la OCD komanso nkhawa.

Koma pali uthenga wabwino. M'miyezi yapitayi, ndasanja njira zingapo zomwe anthu azaka zonse atha kuphunzira kuthana ndi zovuta zama psychophysiological pochita zosavuta tsiku lililonse "ma vagal maneuvers" omwe amachititsa "kuyankha kosangalatsa" kwamanjenje amanjenje ( PNS) pogwiritsa ntchito minyewa yanu ya vagus.

Kulumikizana kwa Vagus-Brain Kungathe Kuchepetsa "Kulimbana, Kuuluka, kapena Kuyimitsa" Mayankho a Kupanikizika

​ Vagus amatanthauza "kuyendayenda" m'Chilatini. Mitsempha ya vagus imadziwika kuti "mitsempha yoyendayenda" chifukwa ndi mitsempha yayitali kwambiri mthupi la munthu ndipo ili ndi nthambi zingapo zomwe zimayambira muubongo ndikuyenda mozungulira kupita ku viscera yotsika kwambiri yamatumbo yomwe ikukhudza (ndikukopa) pafupifupi chiwalo chilichonse chachikulu panjira. Mitsempha yanu ya vagus imathandizira kukambirana kosalekeza pakati pa malingaliro anu, ubongo, ndi zochitika zapakati (chilengedwe mkati) cha thupi lanu. Nyini imagwiranso ntchito ngati njira yayikulu yolumikizirana kudzera pa "gut-brain axis" yolowera yomwe imatumiza mauthenga "kumtunda" kuchokera kuubongo mpaka m'matumbo ndi "kutsika" kuchokera m'matumbo mpaka muubongo. Chofunika kwambiri, pothana ndi nkhawa, mitsempha ya vagus ndiye wamkulu wa dongosolo loletsa kuponderezana kwamankhwala lomwe limafanana ndi mayankho okhumudwitsa a "nkhondo-kapena-kuthawa" kuti asunge homeostasis ndi chisomo chapanikizika.

M'mbuyomu, dongosolo lamanjenje la parasympathetic lakhala likufaniziridwa ndi mabuleki pagalimoto chifukwa PNS imachedwetsa mayankho olimbana ndi kuthawa kapena kuwuluka munthawi yamanjenje. SNS ndiyofananira ndi gasi chifukwa imakulitsa nkhawa popopa adrenaline, cortisol, ndi mahomoni ena opanikizika mu dongosolo lanu lamanjenje. Komabe, m'zaka zaposachedwa, zawonekeratu kuti malo otsekemera oyenera mthupi mwanu amayimiriridwa bwino ndi oyimitsidwa-U momwe mumatulutsa "tonic" ya adrenaline ndi cortisol munjira yomwe imalimbikitsa eustress (kupsinjika kwabwino) ndikuwongolera oomph omwe amafunikira kuti agwire tsikulo ... kwinaku akutulutsa acetylcholine ndi GABA zomwe ndizopumira (zodzipangira zokha) zomwe zimathetsa nkhawa komanso mavuto (kupsinjika koyipa).

Pazosavuta, pankhani yosunga "Guts-Wits-and-Grace Under Pressure" (womwe ndi mutu wogwira ntchito m'buku langa lotsatira) ndimakonda kuyang'ana pa yin-yang komanso kukoka kwamphamvu kwa chisangalalo cha adrenaline komanso choletsa acetylcholine monga magulu awiri oyendetsa magulu achifundo komanso omvera mwachisawawa a dongosolo lodziyimira pawokha.

Mu 1921, pomwe acetylcholine idadziwika koyamba ndi Wopambana Mphotho ya Nobel Otto Loewi, adatchula za neurotransmitter iyi malowo (vagus substance) chifukwa minyewa ya vagus imawoneka ikutulutsa china chomwe chimachedwetsa kugunda kwa mtima ndikutonthoza dongosolo lamanjenje ngati chodekha. Pambuyo pake, akatswiri azamisala adazindikira kuti kupuma pang'onopang'ono, kwakanthawi kochepa kumapangitsa kuti munthu ayambe kupumula mwa kubisa "vagus substance" (yomwe imadziwikanso kuti acetylcholine) m'magazi.

Chifukwa vagusstoff imachedwetsa kugunda kwamtima wina akatulutsa mpweya, kuyeza kupindika kwapakati pa Heart Rate (HRV) ndikosavuta kwakulimbitsa thupi kuti athe kudziwa momwe minyewa yamankhwala ilili yathanzi komanso mayankho olimba am'magulu amtundu wa acetylcholine komanso kuchuluka kwa vagal tone (VT) popita nthawi.
