How Does It work?
Once eaten, caffeine is quickly absorbed into the bloodstream from the gut.
From there, it travels to the liver and can be broken down into glands that affect the function of various organs.
That being said, the main effect of caffeine is on the brain.
It works by blocking the effects of adenosine, which is a neurotransmitter that relaxes the brain and makes you feel tired.
Generally, adenosine levels build up day by day, which makes you more tired and makes you want to sleep.
Caffeine helps keep you awake by connecting to the adenosine receptor in the brain without activating it. It blocks the effects of adenosine, which reduces fatigue.
It can also increase blood adrenaline levels and increase the brain activity of neurotransmitters dopamine and norepinephrine.
This mixture further stimulates the brain and stimulates the state of excitement, alertness, and meditation. Because it affects your brain, caffeine is often referred to as a psychoactive drug.
In addition, caffeine begins to apply its effects quickly
For example, the amount found in a cup of coffee can take up to 20 minutes to reach the bloodstream and about 1 hour to reach full effect.
