Default Beware Of Coffee !!!

القهوة تسبب النسيان



واشنطن - إذا كنت تعاني من حالات نسيان متكررة فلابد أن تبتعد قدر الإمكان عن القهوة !.. فقد وجد الباحثون أن فنجان القهوة الصباحي الذي يبقي الإنسان نشيطا ومتيقظا أثناء النهار قد يضعف الذاكرة قصيرة الأمد ويعطل القدرة على تذكر كلمات معينة

وأوضح الباحثون أن مادة الكافيين الموجودة في القهوة تجعل من الصعب تذكر الكلمات المناسبة التي يحتاجها الشخص للتعبير حتى وإن كان يعرفها وهي الظاهرة التي تصيب البعض ويعبرون عنها "بأن الكلمة على طرف لساني ولا يمكنني تذكرها".

ويعتقد الباحثون في الكلية الدولية الإيطالية للدراسات المتقدمة، أن الكافيين ينشط المخ ويحسّن اليقظة والمزاج والوظائف الإدراكية عند الإنسان عبر تعطيل العمليات الدماغية الأخرى وهو ما يؤدي إلى نسيان الكلمات المطلوبة. وفسّر الباحثون في مجلة " علم النفس السلوكي" أن الكافيين يساعد في بناء الذاكرة قصيرة الأمد في بعض الحالات ولكن في حالات أخرى يجعلها أسوأ مشيرين إلى أن هذه المادة قد تضعف أو تنشط الذاكرة وفقا لما يحاول الإنسان تذكره


وقام الخبراء في كلية ترينتي بدوبلن بمتابعة 32 طالبا تم تقسيمهم إلى مجموعتين، أعطيت الأولى 200 ملليغرام من الكافيين، وهو ما يعادل شرب كوبين من القهوة الثقيلة وتناولت الثانية مادة غير فعالة ثم تحليل إجاباتهم على 100 سؤال من المعلومات العامة التي تتطلب كلمة واحدة فقط. ووجد هؤلاء أن إجابات الطلاب الذين تعاطوا الكافيين كانت غير دقيقة وعبروا عنها بالكثير من الكلمات التي يمكن اختصارها بكلمة واحدة فقط وواجهوا صعوبات في تذكر الجواب المناسب مقارنة بالمجموعة الثانية. ويحاول الباحثون الآن تحديد تأثير الكافيين على الأشخاص الذين يشتكون من صعوبات في استعادة الكلمات وتذكرها
Thank You ...

I drink coffee everyday ... w i encounter this problem a lot :
الظاهرة التي تصيب البعض ويعبرون عنها "بأن الكلمة على طرف لساني ولا يمكنني تذكرها


my short term memory is kind of bad ... it seems this could be related to the coffee drinking issue ...

Now I have a difficult choice to do : either quit drinking coffee or continue with this problem !!!!!

mmmmmmmmmmmm i get used to this problem, but i don't think i can get used to not drink coffee

P.S: for those who have exams, it's better not to use coffee as an alert material, a goodnight sleep is much better than staying awake all night.

Thank You ...

Energy drinks vs. coffee


NEW YORK (Reuters) - Despite such speedy-sounding names as "Full Throttle," "Amp" and "Rush," energy drinks pack a punch that is generally no stronger than coffee, according to a report released on Monday.

A comparison of 12 popular energy drinks, published in the September issue of Consumer Reports, found that the caffeine in 8 ounces of various brands ranged from 50-145 milligrams (mg), though most were in the 75- to 80-mg range.

Results were rounded to the nearest 5 mg.

By comparison, the caffeine in an 8-oz cup of brewed coffee can range from 65-120 mg, with an average of 85 mg, according to the National Coffee Association.

The least-caffeinated energy drink Consumer Reports tested was the fruit punch-flavored offering by Target Corp.'s private label Archer Farms, with 50 mg. At the high end was the lemon-lime flavored Celsius with 145 mg.
Market-leading Red Bull had 80 mg of caffeine. Sobe No Fear, owned by PepsiCo Inc., had 85 mg of caffeine. Amp had 75 mg of caffeine, while Rush and Coca-Cola Co.'s Full Throttle both had 80 mg.

Jamie Kopf Hirsh, associate editor at Consumer Reports and the report's author, said it was "good news" that energy drinks were not much more caffeinated than coffee, but said consumers should still be cautious.
Even though 8 ounces is the standard serving size for measuring, most containers have more than that, and most consumers drink more than that.
"You don't have to be alarmed by this, you just have to account for it in your daily caffeine intake," Hirsh said, adding that energy drinks, with their graphic video-game-like logos that appeal to young men, could be "coffee for the new generation."

Thank You ...
