Each beverage that contains caffeine acts on the central nervous system.
Speaking in scientific terms, it increases brain excitability by blocking the neurotransmitter adenosine receptors.
There goes coffee as well. When we drink it, we feel more awake, alert, and energized.
A lot of us are classic addicts to this magical beverage, and we can’t even imagine what a day would look like without our coffee ritual.
What’s maybe the most valuable part of drinking coffee every day is that there are many health benefits to it.
It can hype up positive energy, reduce the risk of type-2 diabetes, lower our cholesterol level, and many more.
Besides that, it’s even proven that a certain amount of caffeine will keep us awake plus raise our concentration if we drink it.
But, sometimes, this is not the case.
No matter how many times we reach for our favorite coffee machine, there are just not enough cups to function properly!
Our energize booster is not working.
Our productivity is low and we still feel drowsy no matter how many times we make our favorite beverage.
What’s going on?
The answer to this question is twofold. And now we are going to explain it more thoroughly.
Function of caffeine
There are two main functions that happen in our bodies when caffeine runs through our bloodstream.
First, when we consume coffee it binds with “things” that normally would cause our brain to become active.
This prevents us from sleeping properly like we were not consuming caffeine at the time.
Second, we produce more chemical messengers after drinking coffee which helps stimulate regions of the brain that are involved with self-control and willpower.
The fact is that our central nervous system is more awake and lively when we are influenced by caffeine.
Due to the coffee consumption our receptors and neurotransmitter adenosine are blocked,
and that is how we increase the excitability in brain cells.
Adenosine is a natural compound that is part of our bodies.
When that compound is fully received in the brain’s receptors, we are starting to feel sleepy.
The adenosine slows down the nerve cells’ activity,
which in turn dilates the blood vessels.
At this point, your body and your brain are in need of a cup of coffee,
thus it’s time to reach over your favorite coffee machine and pour some beverage into a mug.
Yikes, this whole process sounds like we are some medical experts, but in reality, it is pretty simple.
What coffee is good for the brain?
The longer the roasting time, the more phenylindanes the coffee beans produce.
This means that coffee that’s dark-roasted has the most protective impact on the brain.
But, what’s phenylindanes though?
They are organic compounds that are found in coffee, especially in dark roasted ones.
They have a harsher, lingering taste, which explains the bitter taste of dark-roasted beans.
Hance, espresso, and other grounded, dark-roasted coffee types will have the best protective impact on your brain.
The chemical in caffeine activates so many diverse areas of the brain that it has become difficult to say which is responsible for its protective function.
Looking at the latest studies, the above-stated facts about coffee and its impact on our brains have been proven.
It actually showed that four cups of coffee per day reduced risk by 50 percent of developing dementia and Alzheimer’s later in life.
Therefore, drinking strong coffee is better than drinking decaffeinated coffee.
When it comes to intelligence, there are no guarantees that coffee will make us smarter, but it does show promise in improving our memory and thinking skills.
Stats have shown that people who consume 250-400 mg of caffeine every day had better short-term memory performance than non-caffeine drinkers
while also retaining more information over a 24 hour period.
So, dear coffee lovers, the ones that are on the caffeinated end, after this, we are 100% staying on the dark side.
Not only that we’ll have more energy but we’ll also protect our health from certain diseases.
It’s a win-win for everyone.
