You are feeling tired and you wonder if you should take a nap or drink coffee?

Here comes the “coffee nap” (drinking coffee followed immediately by a short nap) and, according to a few, new, brain studies, it may be the best solution to beating fatigue.

The reason? Effectively timing the interplay of caffeine molecules with adenosine receptors in the brain and sleep causes the caffeine to work better at keeping you alert once you wake up.

It’s important that the nap be short: only 15-20 minutes max. It’s OK if you don’t fall asleep: just resting in a calm, tranquil, quiet environment has the same effects. But you have to drink the coffee relatively quickly, or it will mess up the timing of the reaction.

疲倦的時候你會想小睡片刻還是喝杯咖啡?

根據幾項最新的大腦研究指出，「咖啡盹」(即喝杯咖啡後馬上小睡片刻)，可能是解決疲倦的最佳方法。

原因：準確的計算睡眠時間，以及有效的利用咖啡因分子與大腦內腺苷受體之間的相互作用，可以讓咖啡因的提神功能，在你一覺醒來後，發揮得淋漓盡致。

關鍵在於小睡的時間不能太長，最多15-20分鐘。就算你睡不著，只是平靜地在一個安靜的環境休息，效果也一樣。同樣要注意的是，要儘快喝完咖啡，否則會打亂反應的時間。
