Kwenzekani uma uphuza izinkomishi ezingu-300 ngosuku?

Ososayensi kwelinye lamanyuvesi aseNgilandi ngesikhathi ukuhlolwa kwe-laboratory ehlulekile kwabanika abafundi ababili isilinganiso se-caffeine esilingana nezinkomishi ezingu-300 zekhofi. Ukuhlolwa kwenziwa eNyuvesi yaseNorthumbria e-Faculty of Health and Life Sciences ngoMashi 2015. Kungekudala kuvele leli cala enkantolo yaseNewcastle, ngokusho kombiko wendawo (Sunderland Echo).

Imiphumela emibi

Ngokushesha ngemva kokuthola umthamo omkhulu we-caffeine, abafundi abaneminyaka engu-20 baqala ukubhekana nemiphumela emibi kakhulu, kubandakanya ukuzondeka, umbono obonakalayo, ukuzamazama komzimba nokushaya kwenhliziyo ngokushesha. Bese bathunyelwa ekliniki yokunakekelwa okujulile ye-dialysis. Lena inqubo yezokwelapha esetshenziselwa ukususa izinto eziyingozi kanye namanzi amaningi ngokwegazi. Njengomthetho, abantu abanomsebenzi okwanele we-renal bayadlulisa. Abafundi bahlala enkonzweni enkulu yokunakekela izinsuku eziningana.

Kungani kwenzeka iphutha

Kodwa kungani abafundi bethola isilinganiso esifanayo se-caffeine njengokungathi babedakiwe izinkomishi ezingu-300 zekhofi? Ukuzama ukuhlola ukuhlolwa kwe-caffeine emzimbeni ngesikhathi sokuqeqesha ngokomzimba. Njengengxenye yokuhlolwa, abafana ababili baphuza isisombululo samanzi e-orange, amanzi kanye ne-caffeine powder. Ukudideka kwakungenxa yokuthi abasebenzi belabhoratha babalwa amanani okudingekayo abasebenzisa i-calculator efonini ephathekayo, futhi ngengozi bahambisa iphuzu lesimanje. Iyunivesithi nayo yathi amathebulethi asekuqaleni asetshenziselwa lolu hlobo lwezilingo, kodwa eminyakeni embalwa eyedlule bayishintshela ku-powder ehlanzekile.

Lephutha elikhulu lichaza ukuthi abafundi bathola u-30.7 no-32 amagremu we-caffeine esikhundleni se-0.3 g. Ukuqhathanisa: indebe ejwayelekile yekhofi iqukethe cishe u-0.1 g we-caffeine. Ngaphezu kwalokho, abantu basekuqaleni babulawa ngenxa yokusetshenziswa kwezigremu ezingu-18.

Isibonelelo sokwaziswa

Abamele iNyuvesi yaseNorthumbria batshele inkantolo ukuthi "babenesihawu ngokujulile futhi ngobuqotho." IYunivesithi ikhokhele abafundi abangu-£ 400,000 ($ 50,4100) ngenxephezelo ngokuhlangenwe nakho okungajabulisi futhi okusongela impilo.

Ngenxa yesiphambeko, bobabili abafundi balahlekelwa isisindo, futhi omunye wabo wabika ukulahlekelwa inkumbulo yesikhashana. Ngenhlanhla, abasenayo izimpawu ezingathandeki.

Eminyakeni yamuva, kuye kwanda inani labantu abasebenzisa i-caffeine powder njengomuthi okwandisa ukukhiqiza. Le ndaba iyisikhumbuzo sokuthi i-caffeine isengaba yingozi, noma ngabe iyisidakamizwa esiyithandayo.
