Isibali Se-Caffeine Nokulala
I-caffeine ayipheli emzimbeni lapho umuzwa wokukukhuthaza uphela. Faka isiphuzo sakho sokugcina nesikhathi sakho sokulala ukuze silinganisela ukuthi ingakanani esasele emzimbeni wakho lapho uzama ukulala.
Isikhathi se-half-life se-caffeine sicishe sibe amahora angu-4 kubantu abadala abaphilile, kanti ibanga cishe lingu-2 kuya ku-8. Ocwaningweni olulawulwayo, umthamo ongu-400 mg waphazamisa ukulala ngisho noma wawuthathwe amahora angu-6 ngaphambi kokulala.
Indlela isilinganiso esisebenza ngayo
I-caffeine ikhishwa emzimbeni ngesivinini esicishe sibe njalo: njalo uma kudlula uhhafu wempilo, cishe isigamu salokho okusale siyaphela. I-European Food Safety Authority ibeka uhhafu wempilo ku-cishe amahora angu-4 ngokwesilinganiso kubantu abadala abanempilo, kanti phakathi kwabantu kuba cishe kusuka emahoreni ama-2 kuya kwayi-8. Isibali siphindaphinda umthamo wakho ngo-½ kuhhafu wempilo ngamunye ophakathi kwesikhathi osiphuze ngaso nesikhathi sokulala kwakho. Amanani e-caffeine esiphuzweni ngasinye avela kwi-U.S. Food and Drug Administration; lapho i-FDA inikeza ibanga, sisebenzisa inani eliphakathi kwalo.
Lokhu kuwukulinganisa, hhayi ukukala. Uhhafu wempilo uba mude ngesikhathi sokukhulelwa (i-EFSA ibika amahora angu-6–16) nakwabesifazane abaphuza amaphilisi okuvimbela ukukhulelwa, bese uba mfushane kubabhemayo. Inkomba ka-100 mg isuselwa ekuqapheliseni kwe-EFSA ukuthi imithamo eyodwa engu-100 mg ingathinta ubuthongo kwabanye abantu abadala uma iphuzwa eduze nesikhathi sokulala — akuwona umkhawulo ophephile kuwo wonke umuntu.
Lokho okushiwo wucwaningo
- Ocwaningweni olulawulwayo, ukuthatha ama-400 mg e-caffeine amahora angu-0, 3 noma ngisho 6 ngaphambi kokulala kwaphazamisa ukulala kakhulu uma kuqhathaniswa ne-placebo. Ababhali batusa ukugwema i-caffeine eningi okungenani amahora angu-6 ngaphambi kokulala.
- I-EFSA ibheka kuze kufike ku-400 mg ngosuku kanye nemithamo eyodwa efinyelela ku-200 mg njengokuphephile kubantu abadala abaphilile (hhayi kwabesifazane abakhulelwe). Kubesifazane abakhulelwe nabancelisayo, lesi sibalo sifika ku-200 mg ngosuku.
- I-FDA nayo icaphuna 400 mg ngosuku — cishe izinkomishi ezimbili kuya kwezintathu zekhofi eliphekiwe elingu-12-ounce — njengenani elingajwayelekile ukuhlotshaniswa nemiphumela engemihle kubantu abadala abaphilile.

Leli yisilinganiso sokufundisa, hhayi iseluleko sezokwelapha. Uma ukhulelwe, uthatha imithi noma unesifo senhliziyo, buza udokotela mayelana ne-caffeine.

Imibuzo evame ukubuzwa
Ikhafeyini ihlala isikhathi esingakanani emzimbeni wakho?
Ikhafeyini ine-half-life ecishe ibe amahora ama-4 kubantu abadala abanempilo, inobubanzi obucishe bube amahora ama-2 kuya kwayi-8, ngokusho kwe-European Food Safety Authority. Lokho kusho ukuthi cishe isigamu somthamo sisasebenza emahoreni ama-4 kamuva futhi cishe ikota emahoreni ama-8 kamuva.
Mangaki amahora ngaphambi kokulala okufanele uyeke ukuphuza ikhofi?
Ucwaningo olulawulwayo lokulala luthole ukuthi ama-400 mg e-caffeine aphazamise ukulala ngisho nalapho athathwa amahora angu-6 ngaphambi kokulala, futhi ababhali balo batusa ukugwema i-caffeine eningi okungenani amahora angu-6 ngaphambi kokulala. Imithamo emincane nokugaya komzimba kancane kushintsha leso sikhathi, okulinganiselwa yisibali esingenhla.
Ingakanani i-caffeine ekomishini yekhofi?
I-FDA ibala u-113 kuya ku-247 mg we-caffeine ku-12 fluid ounces (355 ml) yekhofi eliphekiwe elivamile, u-71 mg wetiye elimnyama, u-37 mg wetiye eliluhlaza, u-23 kuya ku-83 mg weziphuzo ezithambile ezine-caffeine no-41 kuya ku-246 mg weziphuzo zamandla, konke ngo-12 fluid ounces.
Ingakanani i-caffeine ngosuku ephephile?
Kubantu abadala abaphilile, i-EFSA ibheka u-400 mg ngosuku kanye nemithamo eyodwa efinyelela ku-200 mg njengokuphephile; i-FDA nayo icaphuna u-400 mg ngosuku. Kwabesifazane abakhulelwe nabancelisa ibele, inani le-EFSA lifika ku-200 mg ngosuku.
Ingabe inani elincane le-caffeine lingaphazamisa ukulala?
Yebo, kwabanye abantu. I-EFSA iphawula ukuthi umthamo owodwa ongu-100 mg we-caffeine ungathinta ubude bokulala kanye nendlela yokulala kwabanye abantu abadala, ikakhulukazi uma uthathwa eduze nesikhathi sokulala.
