Rens swallows pure Caffeine | Drugslab
Hello, I'm Rens.
-And I'm Nellie.
And welcome in our Drugslab.
It's really in my body.
I just want to get rid of it.
In this lab we try various kinds of drugsto see what they do to the human body.
If you wonder about a drug, let us know in the comments.
Maybe we'll try it next time.
X.
Y.
did so too.
He asked usabout the effects of caffeine.
Look, this is caffeine.
You don't often see it in powder form, but this is pure caffeine.
Caffeine can be derivedfrom sixty different plants.
Among which guarana, but also tea, cocoa and the coffee bean, of course.
It's found in the world's second-largestcommodity, namely coffee.
.
.
but also in tea, energy drinks, cola, cocoa and sometimes in painkillers.
It gets added to painkillersto counter their soporific effects.
It's legal in the Netherlands, but it is a drug.
.
.
as it has a stimulating effect on the brain, which makes you more alert and sharper.
Caffeine has a similar structureto adenosine, a brain chemical.
Adenosine builds up during the dayand makes that you gradually grow tired.
Caffeine binds to the same receptors, but doesn't make you tired.
That's why employersplace coffee machines at their offices.
.
.
so that their employersstay alert and productive.
There's a funny storyabout the discovery of caffeine.
There once was a goatherdwho was suddenly missing his goats.
Looking for them, he found a bushwith his goats dancing all around it.
So he picked a berry from the bush, which was the coffee bean.
.
.
and also started dancing.
He became buoyant and cheerfuland it turned into one big party.
That was the discovery of the coffee bean.
-A great story.
This is it.
A natural powder with a bitter taste.
It can also be used as a filler for otherdrugs, such as coke, speed or XTC.
Combining caffeine with stimulating drugslike XTC, coke or speed can be dangerous.
Because all these drugs heightenyour blood pressure and heart rate.
The combination can lead to anxietyand cardiac arrhythmia.
Who's going to take it?-Rock, scissors, paper? Yes, the loser takes it.
-Rock, scissors, paper.
It's my turn.
-Yeah.
The belt is on.
This looks very normal.
Since caffeine raises your blood pressure, I'll measure that as well.
Let's have it.
-Doctor Nellie.
130 over 76.
The average is 120 over 80.
So this is fine.
-Perfect.
We'll see what it's likeafter you've taken caffeine.
The average Dutch man consumes600 mg of caffeine per day.
Which is quite a lot, because the recommended maximum is 400 mg.
But it depends on your sensitivity.
Do you consume a lot of caffeine?-Not really.
I don't drink coffee or energy drinks.
-But you do drink tea.
So you'll probably react well to it.
-I'm going to feel it, I think.
You're getting 400 mg of caffeine at once.
You're going to take it with water.
You can also snort it, or drink it in the form of coffee or other beverages.
These are the best-knowncaffeine-containing drinks.
Coffee contains the most.
After that:the energy drink, espresso, tea and cola.
And then the decaf, but even that contains caffeine.
Apparently caffeine makes you sharper and more alert.
.
.
so I have a responsiveness test for you.
I have to press when I see the dot, right?-Let's see how you do before the caffeine.
Come on.
-2430 milliseconds.
I wonder if I'll do better later.
-Me too.
We'll put it away and try again later.
If I look at my energy level now, I don't feel very buoyant or energetic.
.
.
but also not very tired.
Kind of in between, just relaxed.
It's so dry.
I can't swallow it without water.
It's bitter, but not that bitter.
It doesn't taste bad.
It takes about 20 minutes to take effect.
Caffeine gets absorbed very quickly.
Okay, it's been half an hour.
How do you feel? A bit restless, and when I move it feels as if it's going a bit shakily.
Oh, you're trembling.
-I really am.
I really feel restless, almost nervous.
You know, like.
.
.
My heart is beating faster, I can feel that as well.
Really just kind of restless.
It's really in my body, it feels like.
I'm jittery.
When I move, it's very restless.
Not relaxed.
You know? I'm not really sure.
I just feel kind of nervous.
A bit stressed.
Everything is shaky and jerky.
It's not nice at all.
I don't feel at ease inside my body.
You feel edgy.
-I just want to get rid of it.
Breathe deeply in and out.
Caffeine causes your airwaysand cavities to expand.
.
.
so you can breathe more easily.
Do you notice that? Yes, a little.
If I want to stand still, I can.
But it's not nice, I still feel restless.
Let's measure your blood pressure.
See if it's actually higher.
Yes.
Wow, absolutely, much higher.
149 over 83.
It makes sense, as caffeine narrows the blood vessels.
If you're nervous, it helps to take a deep breath.
I also have that now.
I'll be all jitteryand then have to relax for a second.
It's really as if you're aboutto do something exciting.
Shall we test your responsiveness?-Sure.
Gee.
I didn't expect that.
Clearly much fasterthan without caffeine.
While your finger was going like this.
It was trembling like crazy.
I do have to pee real badly.
-Go ahead.
Caffeine is also supposedto make for clearer and faster thinking.
That's why I have a fun test for you.
Here you have all these sticks.
You can remove eight of them.
.
.
until there are two squares left, but they mustn't touch.
Think very big and very small.
-Okay.
So yes.
.
.
One, two, three, four, five.
.
.
Yes, got it.
Good job.
-I was really able to concentrate.
Yes, I noticed that too.
A tough puzzle, but you were really focused.
Yes, you really notice that.
Good news for all those employers whogive their workers coffee.
It really works.
I have to take a leak again.
-No.
And take a dump.
-Well, good luck.
That dump makes sense, as caffeine stimulates the intestines.
People also think caffeine dehydrates you, but that's not true.
Your kidneys work better, so you have to pee sooner.
You took a high dosage of caffeine.
If you take even more.
.
.
you increase the risk of headaches, anxiety attacks.
.
.
but also heart palpitationsand arrhythmia.
The first hour you reach your peak andget jittery, and then it slowly winds down.
It takes about five hoursto leave your body.
If after that peakyou take caffeine again.
.
.
it immediately kicks in and you'reat the same level of intensity again.
Yes, it's accumulative.
I notice that now, after an hour, I am a little more relaxed again.
Not as restless as before, I'm happy to say.
This feels much better.
This was Drugslab for this week.
I wonder how you'll sleep.
Me too.
Also check the do's and don'tsposted on the channel.
Subscribe and like.
Till next time.
-Bye.
Yesterday after the caffeineI felt bad all day.
I had a headachebut was mainly very nauseous.
I also had trouble falling asleep, but in the end I did.
And when I woke up, it was all gone.
See you next week.
