This happens because caffeine has a chemical structure very similar to that of a substance produced by our own body, adenosine.
Caffeine binds to the body's adenosine receptors, which can be found on the surface of nerve cells.
Second, it may be interacting with adenosine.
Adenosine builds up in your brain through the day making you naturally tired.
For example, adenosine is in your brain and that helps you get sleepy or drowsy.
For example, adenosine is in your brain,
That chemical is called adenosine.
That chemical is called adenosine.
Your brain naturally accumulates adenosine through the day, making you feel tired, but caffeine binds to these same receptors, blocking them from making you feel tired.
Except with chronic caffeine use, your brain actually creates more receptors, meaning you need more caffeine to block that adenosine accumulation.
Our nervous system has specific receptors for neurochemicals, like adenosine, dopamine, and epinephrine,
Our nervous system has specific receptors for different neurochemicals, like adenosine, dopamine, and epinephrine,
Once there, caffeine works by diminishing the effects of a neurotransmitter called adenosine.
Adenosine acts as a suppressor for your nervous system, reducing neural activity and slowing everything down.
It works like this: when you’re awake a chemical compound called adenosine is produced to make you sleepy.
Throughout the day, your adenosine levels rise higher and higher
There are receptors in your brain meant for a chemical called adenosine,
and adenosine is what actually makes you feel tired.
We all know about how the A2A adenosine cycle works in the brain.
My big pitch was for the first 90 minutes of the day, your adenosine system isn't what's in charge.
