Iziselo ze-Energy zinokubeka impilo yentliziyo yakho

• Uphengululo lwe

Inokuba lixesha lokuphinda ucinge ngemidlalo yakho yasemva kwemini. Ngokophando olutsha oluvela kwiAmerican Heart Association, iziselo zamandla zenza okungaphezulu kokukunika iijitters iiyure ezimbalwa. Abaphandi bafumanisa ukuba ukusela nje isiselo esinye samandla kunokunyusa umngcipheko wemicimbi yentliziyo efana ne-arrhythmias (izingqisho zentliziyo engaqhelekanga) okanye ischemia (alonelanga igazi entliziyweni yakho). Ewe. (Ufuna ukuhamba indlela yendalo endaweni? Umthambo wokuphefumla ungawongeza amandla akho nawe.)

Abaphandi balinganise indlela imizimba yabantu ephendule ngayo kwitoti yeRockstar okanye isiselo se-placebo-esasinamanqanaba afanayo eswekile kodwa sasingenayo icaffeine.

Iziphumo zaziphambene. Ukusela isiselo esinamandla kubangele ukunyuka koxinzelelo lwegazi kunye nenqanaba le-norepinephrine labathabathi-nxaxheba eliphindwe kabini. INorepinephrin yhormone yoxinzelelo lomzimba wakho, eyalela impendulo yakho "yokulwa okanye yokubaleka". Kutheni le nto ibalulekile: Xa umlo wakho okanye impendulo yendiza iqala, uxinzelelo lwegazi lwakho luyenyuka. Oku kwandisa ukukwazi kwentliziyo yakho ukufinyela kunye nokulungelelanisa izinga lokubetha kwentliziyo yakho kunye nokuphefumla ngokusabela kuxinzelelo olucingelwayo. Yinto entle xa uyinyani zi kwimeko esongelayo, kodwa kuninzi ukuba intliziyo yakho ikwazi ukusingatha rhoqo. Kwaye ngalo lonke ixesha intliziyo yakho ixinezelekile ngolu hlobo, inokuwuphakamisa umngcipheko wengxaki yentliziyo enkulu ezantsi kwendlela.

Umcimbi ophambili xa kuziwa kwiziselo zamandla kunokwenzeka ukuba yi-combo ye-caffeine kunye noshukela, ngokuka-Anna Svatikova, MD, Ph.D., kunye nombhali ophambili kwisifundo. Ngokutsho kweSvatikova, uphando aluzange luvavanye i-caffeine okanye ishukela ngokwahlukileyo, ngoko akucaci ukuba unokubona iziphumo ezifanayo kunye nekhofi okanye i-soda.

Eyona nto ibalulekileyo? Yehla iziselo zamandla kwaye ufikelele kwiyeza lendalo elinamandla njengeti eluhlaza. (Zama ezi ndlela zingama-20 zokusebenzisa imatcha!)
