- It works like this: when you’re awake a chemical compound called adenosine is produced to make you sleepy.
它的原理是這樣：當你清醒時，名為腺苷的化學物質會被製造出來，導致你想睡覺
- Throughout the day, your adenosine levels rise higher and higher
經過一整天，你的腺苷含量會越來越高

- down ATP for energy, the byproduct adenosine builds up and activates sleep control neurons
以產生能量的同時，隨之產生的腺苷刺激並促進了腦下視丘附近
- brains ignore that buildup of adenosine, and then to fight the stimulants, many people
大腦忽視腺苷濃度的上升。而為了拮抗咖啡因等興奮劑，許多人

- Once there, caffeine works by diminishing the effect of a neurotransmitter called adenosine.
一旦到了那裡，咖啡因就會通過減少一種叫做腺苷的神經遞質的作用來發揮作用。
- Adenosine acts as a suppressor for your nervous system,
腺苷作為神經系統的抑制劑。
不可不知！咖啡因對大腦的影響！(How does caffeine affect the brain?)
01:29
- It's all to do with the neuroscience—adenosine is an inhibitory neurotransmitter and so when it binds to receptors in the brain it reduces nerve activity and makes you sleepy.
這和神經科學息息相關。「腺苷」是一種會抑制神經傳遞的介質，當它和大腦的接受器交互作用時，會減少大腦的神經運作，而後導致你昏昏欲睡。
- To the receptors in the brain, caffeine looks just like adenosine and so it can bind to those receptors too, but it doesn't reduce nerve activity, it just stops adenosine binding.
對大腦的接收器來說，咖啡因就像腺苷一樣，也會和那些接受器產生交互作用，不過它並非減緩神經活動，反而是停止了腺苷的交互作用。

- More specifically, adenosine from consumed ATP builds up in your brain over the course
更具體地說，消耗的ATP中的腺苷會在你的大腦中積聚，在這一過程中，你的大腦中的腺苷就會被消耗掉。
- When caffeine is blocking the adenosine receptor, the adenosine molecules cannot carry out their

- An animal like us eats the sugar, and uses its energy to create molecules of ATP, adenosine
有隻動物，比方說我們吃下醣類， 用其能量合成ATP分子(三磷酸腺苷)。
The science of why coffee is good for you
03:43
- There are receptors in your brain meant for a chemical called Adenosine.
在你的大腦中，有一種叫腺苷的化學物質的受體。
- And Adenosine is what actually makes you feel tired, but when you drink caffeine, the caffeine takes control of those receptors, and doesn't leave any room for the Adenosine, and that's why you feel alert.
而腺苷實際上是什麼 讓你覺得累， 但當你喝咖啡因， 咖啡因採取控制 這些受體， 並沒有留下任何空間 腺苷， 這就是為什麼你覺得警惕。

- While in the brain, this caffeine party crashes adenosine receptors, blocking the normal guest, adenosine, from doing its job.
當在腦部時，這些咖啡因產物會干擾腺苷受體，使原本的腺苷不能作用。
- Adenosine is responsible for slowing down nerve activity in your brains, giving us the cue to calm down and take a nap.
腺苷負責減緩我們腦中神經的活動量，讓我們知道應該要靜下來小睡一下了。
