Okokuqala, makhe sijonge izizathu zokunyusa uxinzelelo lwegazi, kwaye sijonge ubudlelwane phakathi kwekofu kunye noxinzelelo lwegazi:
Oyena nobangela woxinzelelo lwegazi yimithambo yegazi kunye negazi.
Uxinzelelo lwegazi lohlulwe kakhulu lwaba ziindidi ezimbini: uxinzelelo lwegazi oluphambili kunye noxinzelelo lwegazi lwesibini. Noko ke, kungakhathaliseki ukuba yeyiphi na, ingozi yokugula iya kwanda ngenxa yemikhwa yokutya, umsebenzi ongafanelekanga nokuphumla, ukutyeba ngokugqithiseleyo, ukusela ngokugqithiseleyo noxinezeleko oluphezulu, nto leyo ebangela ukuba abaguli bale mihla baluphale ngokuthe ngcembe.
Kukho izinto ezimbini eziphambili ezibonisa uxinzelelo lwegazi: Ukuxhatshazwa kwe-Vascular kunye nokuhamba kwegazi.
- Njengoko umzimba womntu ngokuthe ngcembe uguga, imithambo yegazi iya kuguga, kwaye kuya kubakho 'ukungcola' okuninzi kudonga lwemithambo yegazi, okuya kukhokelela ekugqityweni kodonga kunye nokucutheka kobubanzi bemithambo yegazi, nto leyo efana nokuthintela. Ukongeza, imithambo yegazi ngokuthe ngcembe iya kuphulukana nokunwebeka kwayo ngokukhula kwaye ibe ngumbhobho ogobileyo, nto leyo eyenza kube nzima ukuhambisa igazi. Ngoko ke, kufuneka sinyuse uxinzelelo lwegazi ukwenza ukuba igazi lihambe kakuhle.
- Ukuba amafutha egazi kunye ne-cholesterol ephezulu kakhulu, i-viscosity yegazi iya kuba phezulu kakhulu, kwaye isantya sokuhamba kwegazi siya kuncipha. Iziqhotyoshelwano ezininzi ziya kufakwa kwimithambo yegazi, kwaye isantya sokuhamba kwegazi siya kuba sincinci kwaye sincinci. Kuba yonke iseli emzimbeni idinga ukuhambisa izondlo ngomjelo wegazi, kwaye ke inokuphila kwaye iqhubeke imetabolism. Xa ukwanda kwemithambo yegazi kunye nokuhamba kwegazi kuncipha, intliziyo inokusebenzisa amandla amaninzi kuphela ukufikelela kwinjongo yayo ukuze kuhanjiswe igazi kuwo onke amalungu omzimba, kwaye uxinzelelo lwegazi luyanyuka.
I-caffeine kunye ne-diterpenoids zizona zinto ziphambili kwikofu ezichaphazela uxinzelelo lwegazi. Imiphumo ye-caffeine emzimbeni womntu iyahluka ngokugxininiswa kunye nomthamo wokuthatha. Ukugxininiswa okuphakathi kunye nomlinganiselo ofanelekileyo wekofu kunokuvuyisa ingqondo yomntu, ukuvuselela umoya kunye nokuphucula ukukhathala. Kodwa i-caffeine kwikofu iya kubangela ukunyuka okufutshane kodwa kunobundlobongela kwixinzelelo lwegazi, ngakumbi kubantu abatyebileyo okanye abadala.
Olunye uphononongo lukholelwa ukuba oku kungenxa yokuba icaffeine inokuthintela ihomoni enceda ekudaluleni imithambo, kwaye inokukhuthaza ukukhuselwa kweadrenaline, ikhuthaza ngakumbi ukunyuka koxinzelelo lwegazi. Nangona kunjalo, akukho uphando olubonisa ukuba ikofu inokuchaphazela uxinzelelo lwegazi ixesha elide.
Kubantu abanengxaki yokulawula uxinzelelo lwegazi okanye isiphumo esibi sokunciphisa uxinzelelo lwegazi, zama ukusela ikofu encinci okanye akukho, singasathethi ke ngokusela ikofu eninzi ngexesha elifutshane okanye xa uziva unovalo, kungenjalo kuya kuba lula ukukhokelela ekubetheni kwentliziyo, i-tachycardia kunye nezinye iimpawu ezimbi.
Abantu abasele benoxinzelelo lwegazi baquka nezinye iziselo ezinecaffeine, ezifana neti eyomeleleyo, ekwaqulethe amanqanaba aphezulu ecaffeine. Kubantu abaqhele ukusela ikofu ixesha elide, kucetyiswa ukuba banciphise kancinci ikofu abayiselayo, kwaye bachithe malunga neveki ukuba bangayiseli.
Kuba ndiyekile ukusela ikofu ngesiquphe, kulula ukuba ne-caffeine phased headache, eyenza abantu bazive bengakhululekanga. Ukongeza kwizigulane ezine-hypertension, abantu abaqhelekileyo abakhuthazwa ukuba basele ikofu eninzi, kuba ukugqithiswa kwe-caffeine kuya kuthintela ukuxutywa kwe-calcium kunye nokwandisa umngcipheko we-osteoporosis. Kulabo abangenako ukuyeka ikhofi, kucetyiswa ukunciphisa ukongezwa kweshukela kunye nezinye iishukela eziphezulu kunye ne-fat-fat condiments, ukwenzela ukuba ungabangeli ukushisa okukhulu kunye nokwandisa ingxaki yoxinzelelo lwegazi.
Akukho mntu wazi umzimba wethu ngaphezu kwethu. Ukujongwa koxinzelelo lwegazi lwemihla ngemihla kunokusinceda siqonde ngcono uxinzelelo lwegazi lwethu kwaye siphile ubomi bolonwabo.
