A new small study finds that quenching your thirst with water may give your brain a boost.
Results showed that subjects who drank about three cups of water (775 milliliters) before taking a battery of cognitive tests performed better on a test measuring reaction time than subjects who did not drink water.
This difference was especially noticeable when the subjects were especially thirsty, with researchers speculating that being thirsty may take attention away from the task at hand, slowing response time.

In one test on rule-learning, however, thirsty subjects actually fared better, but researchers are not clear why.
“It might be that physiological processes [of drinking or not drinking water] affect performance on different tasks in different ways,” study researcher Caroline Edmonds, of the University of East London School of Psychology told LiveScience.
In the study, 34 adult subjects were asked to abstain from food and drink starting at 9pm before coming into the lab for testing the next morning. In some cases, subjects were offered a cereal bar with water for breakfast. On another day, they were offered a cereal bar with no water.
Prior research has found that water consumption can improve memory in children, LiveScience reports.

一份新的小規模研究發現,喝水解渴或許能增進你的腦力。
研究結果顯示,先喝約三杯水(七百七十五毫升)再做一系列認知測驗的人,測量反應時間的測試表現,比測驗前沒喝水的人好。
這種差異在受測者特別渴時尤其明顯,研究人員揣測,感到口渴或許會分散人對手邊工作的注意力,延緩反應時間。
然而,在學習規範這項測驗上,口渴的人確實表現比較好,但研究人員不清楚為什麼。
「或許是(喝水或不喝水的)生理過程,以不同方式影響不同工作的表現」,進行這份研究的東倫敦大學心理學院研究人員卡洛琳.艾德蒙向「生活科學」網站表示。
在這份研究中,三十四名成年受測者被要求在測驗前一晚九時起不要進食,然後次日上午到實驗室受測,受測前提供部分受測者穀物棒配水當早餐。另一天只提供穀物棒,沒有搭配水。
生活科學網站報導,此前的研究已發現,喝水能提升兒童的記憶力。

Let’s explore another delicacy primarily known to Tainan locals: floating milkfish in thick soup. Despite its peculiar name, this dish is another Tainan specialty that showcases the popularity of milkfish, which is made into fish paste and served in thick soup. Unlike the version with tutuo fish, which also adds other ingredients to its thick soup, the floating milkfish version primarily features the “floating fish” itself in its thick soup, ensuring that the fish paste remains the star of the dish. 讓我們來探索另一道台南人熟悉的美食:浮水魚羹。這道菜名奇特的美食,再再展現了台南虱目魚料理的多樣。浮水魚羹是用虱目魚漿做成的羹品,雖然和𩵚魠魚羹一樣是羹湯,但不像𩵚魠魚羹會在湯中加入其他食材,而是讓虱目魚漿成為這道料理的主角。 peculiar (adj.) 獨特的;古怪的 The belly of a milkfish is considered the most
