Hello and welcome to the first episode of the Lab,

A new series here on Asap Science, where we take your questions and turn them into experiments,

My name is Mitch -And I'm Greg and we are ASAP Science.

And don't worry, the animated videos are still gonna be coming out every week, but on Sundays leading up to the new year,

And Mitch, what exactly are we doing today

So today, we are actually looking at the science of pain

and we're gonna start out by having a lot of spicy peppers to understand

And then, we're gonna be putting our hands in some really cold water and see if swearing can actually can help with pain

And finally, we are gonna be getting electrocuted to talk about the anticipation of pain and how awful that is.

Do you think you are gonna be good at this?

No? I'm like so weak. Okay, I'm the weak one of this group.

I have red hair genes, so you know, I can like handle anything.

They are all gonna be challenges, by the way. So, should we just... should we just start?

Alright, first up, we have our spicy pepper challenge

We've ordered these peppers from the least spicy to most spicy

And then, we have a list of facts. So, every time we bite a pepper, we have to spew off a spicy pepper fact

And, this is the hottest pepper in the world: the California (Carolina) Reapers

Hopefully, we are not gonna projectile our vomit on the camera

And the first person who grabs this milk for release... relief loses the challenge

Spicy peppers excite receptors that usually respond to heat, and these are known as nociceptors

These nociceptors respond to temperature, extremes.... Oh my God, it's actually really hot.

And mechanical stimulus, but they can also obviously respond to chemicals

I wanna just spit it out and drink my mlik

When you eat a hot pepper like this one, your central nervous system gets very confused.

Capsaicin is the active ingredient in hot peppers

Which stimulates the nerve to respond to mild temperature increases,

It sends two signals to the brain, that it's warm and that it's an intense stimulus

I don't... I don't think I can do this any longer.

It's getting worse, like it's going.. -Look I'm drooling

Oh my god that feels so good, just drink your milk. - NO

The signal creates the same physical reaction to heat, that includes vasodilation, sweating and flushing...

Uhm.. and that's it! You sweat and you flush, and you vaso.. My hand!

My hand feels weird. - I'm sweating, I'm sweating.

Okay, I'm gonna read my other fact, because I already lost.

My right hand is tingling.. I TOUCHED MY EYE!

-Oh my god, are you okay? Don't touch it more!

Wait, I think I need to put milk in my eye.

It was interesting, one researcher actually gave rats spicy foods to see if they would actually like it,

and it turns out humans are one of the only animals in the world that will choose to eat spicy things

Choose to eat spicy things over stuff that actually isn't spicy, so...

How do you feel, explain to us how you feel.

-Like a fool for saying, that I was like, I am so good at pain.

Okay Mitch, so why is milk helpful for us.

Well, so water is not helpful because Capsaicin is actually hydrophobic,

so the water doesn't really do anything except swash it around all around your mouth,

whereas the milk actually absorbs it, brings it down to your stomach and actually is a chemical reaction

-And also, the relief that you feel when drinking this milk, excites the pleasure sensors of your brain,

which is why this feels so good right now.

And why people go back to spice, even though they know it's awful.

Also, I'm gonna give up on coffee. Ghost pepper every morning? *snaps fingers*

So pain actually is something that is used to protect your tissue from damage,

so for example, if you touch a hot burner, your tissue is getting damaged immediately

and you feel the pain immediately. But some things actually take more time to feel the pain.

So to elicit some slow pain, we have these buckets filled with ice

we're just gonna put our hands in them to see how long we can last

but the one caveat being that Greg is allowed to swear and I'm not.

Okay! Are you ready for more pain? -I think so... okay time to roll up and put in?

Okay, we have to do the exact same time to be as scientifically accurate as possible!

A study actually found that when people were allowed to f***ing swear,

they were able to keep their hands in ice water for on average 40 seconds longer
