Fear - umuzwa wokuthi kuyinto ajwayelekile kumuntu kusukela ekuzalweni. Ngokwezinga elikhulu noma elincane, umuzwa yokwesaba, ngamunye wethu ihlangabezana cishe nsuku zonke. Kodwa kungani sizizwa lo muzwa, yini lo mshini nesenzakalo lesimo? It kuvela ukuthi imbangela le hormone lokujabulela yokwesaba. Funda kabanzi mayelana physiology okuvela imizwa enjalo - material yethu.

Yikuphi lokhu kwesaba?

Fear - iyona isimo sangaphakathi umuntu, okuyinto senziwa noma yiluphi uhlobo ingozi, futhi ezihambisana okuvela ezimbi ezabehlela ngokomzwelo. Lo muzwa ezingeni imizwelo engokwemvelo ezilwaneni, kokuvela ngesimo ukusabela zokuzivikela. Ngokuvamile, indlela abantu lokhu imizwelo afanayo: uma kukhona ingozi emzimbeni ocushiwe yonke imithombo kungenzeka ukuba akwazi ukunqoba izingqinamba usongo.

Ngokwesibonelo, thina akazange anqikaze uvale amehlo ethu, thina ukwandisa ibanga ukusuka emthonjeni, obangela ukwesaba nokunye. N. Kwezinye izimo, abantu akazange abaleke, fihla kusuka kwavela ingozi. Nakuba lo mshini ukwesaba abantu ezahlukene okufanayo, indlela abantu abasabela ngayo umfutho waphawula okuphambene. Ngakho, uma umzimba oyedwa ku usongo nesenzakalo oyenza izinqubo engqondo, uzama ukuthola indlela yokuphuma yalesi simo, nezinye, kunalokho, iwela stupor. Kunoma ikuphi, ukusabela komzimba yokwesaba kungenxa ukukhululwa bungene egazini into ethile. Mayelana anjani hormone obhekene nokwesaba, thina uchaze ngezansi.

Ukwesaba njengoba isazela self-ukulondolozwa

Ukhishwa isilwane futhi impendulo womuntu ukuba ingozi abasafufusa sitholakala ezakhini zofuzo futhi ngokuyinhloko okungokwemvelo. Ngakho, isifundo Waveta kutsi ngisho umntwana osanda kuzalwa azizwa ukwesaba ezahlukene. Khona-ke, ngaphansi kwethonya ukuxhumana kwabantu, imizwelo kuba amafomu ahlukene nezinkulumo, kodwa kwakuyindlela abasabela ngayo nokho yingozi umfutho uhlala ezingeni isazela.

Ucwaningo we physiology ukwesaba inani elikhulu imisebenzi yesayensi, kwezobuciko nokulotshwa kwalo. Naphezu kwakho konke lokhu, kusekhona eziningi nezindaba nezokusigcoba ezihlobene mshini kumiswa impendulo zokuzivikela. Kuyaziwa ukuthi izimpawu zokwesaba kubangele amahomoni ekhiqizwa nezindlala adrenal, okungukuthi i-adrenaline futhi cortisol. Kodwa kungani izinto esifanayo ibe ibambe iqhaza ekwakhekeni ukusabela akuhambisani okuphambene (ie excitation futhi okusithiyayo) kubantu kuya umfutho ofanayo - namanje akwaziwa ukuthi waphelelaphi.

Mshini kumiswa

Kwenzekani emzimbeni lapho kwenzeka ingozi? Okokuqala, ukwaziswa okulethwa yizinzwa engenayo izimpawu cortex cerebral mayelana nokuthola isimo posing basongela ukulondeka komuntu. Ngokulandelayo, umzimba uqala ukukhiqiza okuthiwa yokwesaba-hormone okuthiwa i - epinephrine. Ngebanga lalokho, lokhu izidakamizwa oyenza isebenze ukukhiqizwa cortisol - ukuthi kubangela izimpawu nobuntu ukubonakaliswa kwangaphandle yokwesaba.

izifundo kokulinganisa luye lwabonisa ukuthi phakathi nenkathi lapho umuntu enomuzwa ukwesaba eqinile, cortisol egazini luyanda kakhulu. Ngenxa yalokho, kukhona izimpawu sici isimo enjalo engemihle ngokomzwelo.

ngezigaba

ucwaningo oluningana luye lwabonisa ukuthi ukwesaba kungadalwa izinto eziningi. Kuye lokhu, ukuze uhlukanise umzwelo ezinjalo lezi zinhlobo ezilandelayo:

1. Biology elisuka lasekuqaleni. Kuyinto isazela sokusinda. ukusabela okunjalo akugcini izilwane, kodwa futhi abantu. Lapho ebhekene nengozi sobala ekuphileni ezingeni isazela iqala ukukhiqiza "hormone yokwesaba", okuvumela umzimba ukuze kweso kusebenze zonke izinsiza ezikhona kuliwe nobungozi.
2. Ukwesaba okunjalo yezenhlalakahle zitholwa ngenxa isipiliyoni zanqwabelana. Ngokwesibonelo, ukwesaba yokukhuluma obala noma izinqubo zokwelapha. Lolu hlobo yokusabela amenable ukuba ukulungiswa - enqubeni yokucabanga, logic ukucabanga kungenzeka ukunqoba ukwesaba okunjalo.

izimpawu

adrenalin egazini kubangela inombolo ejwayelekile imizwa yokwesaba uthi. Ngakho, le nto kunomthelela blood pressure kanye vasodilatation - ukudluliswa Oxygen kanjalo ekuthuthukiseni izitho zangaphakathi. Ngakwelinye ihlangothi, supply anda kwezicubu ubuchopho kusiza Bathi ukuze uvuselele ingqondo, ukuze uyothuma amabutho ukuthola izixazululo okudingeka izithathe ukuze ixazulule le eziphuthumayo zamanje. Yingakho, lapho umuntu akuve kwesabeka ku imizuzwana yokuqala umzimba wakhe uzama ukukhulisa ngokunembile ukuhlola usongo ngokwenza kusebenze zonke izinsiza ezikhona. Ikakhulukazi umfundi ukunwetshwa kwenzeka wokubuka emikhulu kanye voltage main motor imisipha kwenzeka ngoba ukusheshisa esiphezulu lapho esidingekayo ukuze aphunyuke.

Ukucindezeleka-hormone okuthiwa i - cortisol

Kulesi indlela yokwesaba alikapheli. Ngaphansi kwethonya adrenaline egazini kwandisa cortisol, noma hormone yokucindezeleka. Ukwandisa ukusebenza yalolu ketshezi kuholela zimpawu:

• palpitations inhliziyo;
• ajulukayo;
• ukoma ku ngalo ingaphakathi ngomlomo;
• njalo ukuphefumula engajulile.

Uma bethi "izinwele bavuka", engqondweni ukuthi kwaba very scary. ngakho-ke ngempela uma umuntu asaba okuthile? Ngempela, isayensi uyazi ezinye izimo ukusabela ngaleyo ndlela ezikhathini ingozi - at izimpande izinwele kancane waphakamisa ngenxa yesenzo hormone. Abacwaningi basikisela ukuthi le mpendulo kuyinto reflex - raspushivayut ngakho inyoni izimpaphe, kanti ezinye izilwane ezincelisayo ukukhiqiza spikes uma kwenzeka ingozi ukuze ukuphila. Kodwa uma isilwane izenzo ezinjalo kungase empeleni ukusindisa izimpilo, ke umuntu lo yokusabela kuphela isazela bakudala self-ukulondolozwa.

Izindlela ukubonakaliswa yokwesaba

yokwesaba izifundo okuye kwenziwa kuye kwabonisa ukuthi kunezinhlobo ezimbili izinhlobo impendulo womuntu ukuba ingozi:

• asebenzayo;
• azithele ngabandayo.

Ngakho, endabeni yokuqala, umzimba kweso oyenza yonke izivikelo zomzimba. Kulesi simo kakhulu kwandisa amathuba. ISidlo Ezimweni eziningi lapho yokwesaba indoda kwenziwe izinto engajwayelekile kuye: .. yokweqa isithiyo okusezingeni eliphezulu, imithwalo esindayo, bahambe amabanga amade ngesikhathi esifushane, njll Ngaphezu kwalokho, imizamo ukuphinda isimo sithi iholidi elinokuthula esinjalo siholela ukwehluleka. Uchaza izici ezifana ukuthi ngesikhathi ukwethuka e eziningi adrenaline ikhiqizwa emzimbeni womuntu. Kuyinto yalolu ketshezi ngesikhathi esifushane oyenza imisebenzi zokuzivikela, okukuvumela ukuthi usebenzise zonke izinsiza ezikhona ukuba akwazi ukunqoba izingqinamba usongo.

ukuphendula Passive kwenzeka uma umuntu ngokungazi ukubufihla kusukela kwavela ingozi. Lokhu kubonakala lantambama (kanjalo iningi izilwane nezinyoni ngesikhathi kusondela ingozi empilweni), amboze ngoba amehlo nomlomo ngezandla zakhe. Ngokuvamile izingane ukufihla ngaphansi ingubo noma embhedeni. Kuyaziwa ukuthi ukusabela okunjalo nazo zibangelwa iqiniso lokuthi adrenal cortex i-hormone ikhishwe ukwethuka. Kodwa yingakho abanye abantu ukuthatha amagxathu asebenzayo ukuqeda ingozi, kanti abanye bayahlala kuze kuphele usongo namanje akwaziwa ukuthi waphelelaphi ngoba abacwaningi yale nkinga. Kukhona iziphakamiso ukuthi ehlangene nakho komphakathi yomuntu nezici zakhe ngabanye buyinkimbinkimbi.

imiphumela

Kungakhathaliseki yokwesaba kuyingozi? Lo mbuzo ukuhlangabezana ngokucacile odokotela - imizwelo enjalo ithwala izinguquko ezinkulu futhi ezinqala emzimbeni ezingeke kodwa kuthinta impilo. Ukwethuka kungabangela kahle ukugeleza kwegazi, hypoxia palsy, nokwanda okuphawulekayo blood pressure yonke imiphumela isikhonzi. Ezimweni ezimbi kakhulu, ukuvaleka kungenzeka imithambo yegazi kanye, ngenxa yalokho, ngemuva kokuhlaselwa yisifo senhliziyo.

Fans of ukuzijabulisa kakhulu ukuqinisekisa ukuthi adrenaline egazini inyuka ubungqabavu, kuthuthukisa impilo. Ngempela, lokhu izidakamizwa kubangela nomphumela tonic emzimbeni, futhi benomuzwa wokuthi umuntu nakho phakathi ukwethuka, ngokuvamile kuqhathaniswa bajabula. Naphezu kwalokhu, odokotela bathi amagesi ukwesaba ama-hormone kunciphisa amandla zomzimba. A kwasikhathi sonke emiphumeleni kwengcindezi umthwalo omkhulu phezu esimiso senhliziyo nemithambo yegazi, okwandisa ingozi yezifo ezihlukahlukene kusukela Rosacea ukuba engavamile izitho zangaphakathi.

Ingabe ngizolulama ekwesabeni?

indoda ukwesaba okungafanele njalo imbangela bokuphila - inkinga kungenzeka asuka ngokwengqondo. A-hormone ekhiqizwa umzimba bangase besabe, futhi ukungabi khona i songo ecacile ekuphileni. Ngokwesibonelo, izinkulumo zeningi, ikamelo elimnyama noma izinambuzane ayinangozi ayengayisebenzisa baphathe ingozi yangempela. Noma kunjalo, cishe yilowo nalowo phakathi kwethu asaba okuthile linesisekelo ngokuphelele. Futhi kubonakala hhayi kuphela e umcabango kodwa futhi izinguquko bokuphila. Ngokwesibonelo, abantu abaphethwe zokwesaba ahlukahlukene, ukhiqiza adrenalin, futhi izimpawu manifest nobuntu yokwesaba. Izimo ezinjalo, yebo, zidinga usizo ochwepheshe. Ngaphezu udokotela ngokwengqondo ukwesekwa angabeka sedatives noma amakhambi homeopathic uma kudingeka.

Siyatshelwa ukuthi i-hormone ikhiqizwa at bay, wachaza lo mshini kumiswa imizwa enjalo kubantu. Kungaphawulwa ukuthi ezimweni eziningi yokusabela ukuzivikela enjalo silondoloza indoda engozini. Kodwa ukwesaba okungenasisekelo ingaholela ezinkingeni zempilo ezingathi sína.
