Now the story.

Laughter can make your heart stronger, new research suggests.

The study revealed that being shown TV comedies increased the amount of oxygen being pumped around heart patients' bodies.

This Brazilian investigation also suggests that laughter therapy could reduce inflammation in blood vessels.

You've been looking at the headlines, what's the vocabulary?

We have "having a laugh," "literally," and "first-of-its-kind."

This is News Review from BBC Learning English.

Let's have a look at our first headline.

This is from the Mirror: Having a laugh twice a week could help reduce the risk of heart disease: trial fines.

This headline says that laughter therapy can help reduce the risk of heart disease.

Now, we are going to look at the expression "having a laugh."

Now, this doesn't refer to laughing twice a week, does it?

No. Now, using have with laugh is interesting.

Having a laugh means having a good time.

And here it's talking about sessions of laughter therapy, using comedy programs rather than two individual laughs.

Now, this study is talking about the act of laughing.

But we do often use it like you said to just mean, having a good time.

Now, Phil, didn't you meet some friends after work yesterday?

Yes, we had a great laugh; we had a great time.

And actually, there is another use of this. Beth, I'm gonna tell you something amazing.

You could learn a new language in just three weeks.

No, you're having a laugh. And that, I mean, I don't believe you.

Yes, it's just a little joke. I'm having a laugh.

Let's look at that again.

Let's have our next headline.

This is from the New York Post: Laughter can heal a broken heart - literally: cardiac health study.

We're going to look at the word "literally," which is an adverb.

Here it refers to the adjective broken.

Now, Phil, when can a heart be broken literally?

OK. The headline he's using broken in the sense of doesn't work.

And it's because the study is about people with heart problems.

In this context, literally means the real actual meaning of the word.

So it's a clever headline because broken heart is not usually used literally.

It's more common to use it metaphorically to refer to when somebody is sad, often at the end of a relationship.

But here we see how literally can be used for emphasis and it's often used in a surprising situation.

Here's a surprising situation.

The trains were so bad this morning that it took me literally hours to get to the studio.

Literally hours like two of them.

That's really annoying. And there are literally seconds until we look at this headline again.

Next headline please.

This is from the Independent: First-of-its-kind study finds laughter is indeed good medicine, especially for the heart.

This study is unlike previous research, we are looking at the expression "first of its kind."

Now, Phil, can you explain what kind means here?

Yes, kind means type here.

So if something is the first of its kind, there's nothing like it before.

It's the first of it type and we use it usually for innovations.

If you think about the first smartphone, it was the first-of-its-kind.

Now, this study is the first-of-its-kind according to the headline because it's looking at laughter therapy with heart patients, which hasn't been looked at before.

Ok, let's look at that again.

We've had having a laugh - enjoying yourself joking.

Literally, it's actually real.

First-of-its-kind - different to anything before.

Now, if you've enjoyed this episode, we think you will love the 6-Minute English where we found out why laughter is the best medicine.
