Kungase kube isikhathi sokucabanga kabusha ozongilanda maphakathi nemini. Ngokocwaningo olusha oluvela ku-American Heart Association, iziphuzo ezinamandla zenza okungaphezu nje kokukunikeza ama-jitters amahora ambalwa. Abaphenyi bathola ukuthi ukusebenzisa ngisho isiphuzo esisodwa nje samandla kungandisa ubungozi bezinkinga zenhliziyo ezinjenge-arrhythmias (isigqi senhliziyo esingajwayelekile) noma ischemia (ukunganeli kwegazi enhliziyweni yakho). Yikes. (Ufuna ukuhamba ngomzila wemvelo esikhundleni salokho? Ukuzivocavoca okuphefumulayo kungakhuphula namandla akho.)

Abaphenyi balinganisa ukuthi imizimba yabantu isabela kanjani enkonxeni yeRockstar noma isiphuzo se-placebo-esasinamazinga afanayo kashukela kepha singenayo i-caffeine.

Imiphumela yayihlanya kakhulu. Ukuphuza isiphuzo samandla kubangele ukuphakama kwengcindezi yegazi namazinga wabahlanganyeli aphindaphindiwe e-norepinephrine. INorepinephrine yihomoni yokucindezela komzimba wakho, echaza impendulo yakho "yokulwa noma indiza". Kungani kubalulekile lokho: Lapho impi yakho noma impendulo yendiza yakho ishukunyiswa, umfutho wegazi lakho uyaqhuma. Lokhu kwandisa amandla enhliziyo yakho okwenza isivumelwano futhi alinganise izinga lokushaya kwenhliziyo yakho nokuphefumula ukuphendula ukucindezela okubonakalayo. Lokho kuyinto enhle uma kunjalo kukhona esimweni esisongelayo, kepha kuningi inhliziyo yakho okufanele ikubambe njalo. Futhi ngaso sonke isikhathi lapho inhliziyo yakho icindezelekile ngale ndlela, ingakhuphula ingozi yokuba nenkinga yenhliziyo embi phansi komgwaqo.

Inkinga enkulu uma kukhulunywa ngeziphuzo zamandla kungenzeka ukuthi iyinhlanganisela ye-caffeine noshukela, ngokusho kuka-Anna Svatikova, MD, Ph.D., nombhali oholayo ocwaningweni. Ngokusho kukaSvatikova, lolu cwaningo aluzange luvivinye i-caffeine noma ushukela ngokwehlukana, ngakho-ke akucaci ukuthi ungabona imiphumela efanayo ngekhofi noma ngesoda.

Iphuzu eliyinhloko? Umsele iziphuzo zamandla bese ufinyelela ikhambi lamandla elithe xaxa njengetiye eliluhlaza. (Zama lezi zindlela ezingama-20 zobuhlakani zokusebenzisa i-matcha!)
