Neil
So, Georgie we're going to talk about something a little different today. We're talking about itching. Now an itch is that unpleasant feeling you get on your skin that you have to scratch with your fingers. What sort of things make you itch?
 
Georgie
Well, funny you should ask, because I'm actually wearing quite an itchy jumper at the moment and it's making me want to scratch my skin. What about you?
 
Neil
Well, recently I was bitten by a mosquito and, as you know, when you get bitten by a mosquito, it's really itchy. I had to scratch loads and loads.
 
Georgie
Oh, I hate it when that happens.
 
Neil
It was horrible. In this podcast, we're going to hear from some experts about why we itch and how scratching can be good for us.
 
Georgie
And as usual, we'll be learning some useful new vocabulary.
 
Neil
OK. Well, we're going to start with a quiz question of course, Georgie. It's a bit of a different one today. Dr Henning Holle studies the psychology of itching, and he played some scratching sounds to the guests on the BBC World Service programme CrowdScience. Now the question is, what is being scratched? You have three choices:
 
a)    an arm,
b)    a beard, or
c)    some jeans.
 
Georgie
OK. Well, let's listen... Well, that sounded a bit hairy, so I'm going to go with b) a beard.
 
Neil
Well, we'll find out at the end of the programme.
 
Georgie
So, Neil, I mentioned that my jumper was a bit itchy but sometimes I feel itchy for no particular reason. So, what's going on there?
 
Neil
Well, that's something that the listeners of BBC World Service programme CrowdScience also wondered. They wanted to know the answer to that. The presenter, Anand Jagatia, spoke to itching expert Sonja Ständer to find out more. Let's listen.
 
Anand Jagatia
There's lots of science to unpack here. Sonja, what actually is itchiness?
 
Sonja Ständer
Yeah. So, by scratching the skin, we remove parasites or plants or anything that does not belong on the skin. And so, we start to scratch at the very same area where we itch and remove it. And it can no longer damage the skin and harm ourselves.
 
Georgie
Anand says there's a lot of science to unpack about itchiness. Unpack here means explain.
 
Neil
Sonja explains that when our skin feels itchy, we scratch it, and that helps to get rid of parasites and other harmful things on our skin. Parasites are animals or plants that live on another animal and feed from them.
 
Georgie
So, Neil, itching is our skin's way of protecting itself against harmful parasites. And I have to say, all of this talk of itching and scratching is making me feel a bit itchy right now.
 
Neil
Well, that's interesting because Dr Henning Holle wanted to study whether just thinking about itching makes us more likely to feel itchy.
 
Georgie
Henning and his team studied what happened when people watched videos of itching and scratching.
 
Neil
Let's listen to him speaking to BBC World Service programme CrowdScience.
 
Dr Henning Holle
And what we found in this study was, yes, these scratching videos indeed made people feel itchier. They also started to scratch themselves more spontaneously. So, the answer is basically yes, you can catch a scratch.
 
Neil
In Henning's study, when people watched videos of scratching, they scratched themselves spontaneously. If you do something spontaneously, you do it without being asked or without thinking.
 
Georgie
So, Henning concludes that yes, you can catch a scratch, just like you might catch an illness. Catch in this context means get from someone else.
 
Neil
OK. Georgie, I think it's time for the answer to my quiz question. We had a clip of people scratching and you had to decide what is being scratched.
 
Georgie
I said that was a beard.

Neil
OK. Well, let's see if the people who are listening to this on the programme CrowdScience agreed.
 
Sonja Ständer
It sounds like hairy skin so I would go for the scalp.
 
Anand Jagatia
Yeah, I think it's beard or something because it does sound like there's hair there.
 
Dr Henning Holle
It is definitely hairy skin and Anand was spot on. So, it is indeed a beard scratch that we were listening to.
 
Anand Jagatia
Wow!
 
Georgie
So I was right!
 
Neil
You were. Congratulations!
 
Georgie
OK. Let's recap the vocabulary we learned in this programme, starting with itch, which is an unpleasant feeling on your skin. And something can be described using the adjective itchy.
 
Neil
When you feel an itch, you often scratch it with your fingers by rubbing your nails on the skin.
 
Georgie
If you unpack an idea or scientific concept, you explain it in clear detail.
 
Neil
A parasite is an animal or plant that lives on another animal and feeds on it.
 
Georgie
If you do something spontaneously, you do it without being asked or without thinking.
 
Neil
Catch can be used to mean get from someone else, such as an illness. For example, you can catch a cold.
 
Georgie
Once again, our six minutes are up, but you can test what you've learned with the worksheet on our website, bbclearningenglish.com.
 
Neil
Thank you for joining us and goodbye.
 
Georgie
Goodbye.
