BBC 6分钟英语 我们能增强免疫系统吗

From BBC learning english com. Hello.

This is six minute English from BBC Learning English.

I'm Georgie, and I'm Neil. In this program, we're talking about the immune system, which is the body's

natural defense against getting ill. Now, georgie, is there anything you do to boost your immune system?

Yes, I try to eat lots of oranges, which apparen'tly have lots of vitamin C, and there are lots of things people do to try to improve their immune system and stay healthier, like eating certain foods, taking vitamins, or even activities like swimming in cold water.

We'll find out how useful some of these techniques are in today's program.

But 1st Georgie a question. We all know the common cold now.

That's the illness that makes you cough and sneeze, have a sore throat and headache.

But how many colds does the average adult get in the UK each year?

Is it A? Two to three?

B Four to five, or C Seven to eight?

Hmm, eight would be a lot.

I'm gonna go with a two to three colds a year.

Well, we'll find out at the end of the program.

If you're right now, many people can become ill over the winter with diseases like colds, flu and covid 19 host of BBC radio for program Inside Health, james Gallagher gathered some experts to talk about immune systems, and he started off by asking whether they'd had more illnesses than usual this winter.

Hello. Hi. Right, how has everyone been this winter?

Cause I've had a rotten one, and I have felt constantly ill since about November.

John, I have not had anything yet touch with.

Okay, let's see what I can infect you with by the end of the show.

Margaret, I was pretty unwell in September, I had what presumed to be covered, but I've been all right since my old snuffles aside, eleanor I really want to back me up at No, sorry, I've been absolutely hundred percent ticktty.

Boo. Unlike James, professor John Tragoaning hasn't been ill.

John uses the expression touch word, which is an informal phrase said in order to avoid bad luck.

Talk to Margaret Mccartney was unwell in September, but has only had a few snuffles since.

Snuffles is an informal word used to describe minor illnesses that affect your nose.

We can also say sniffles. Host James is surprised that nobody has been ill, and says to Professor Eleanor Riley, back me up.

If you ask someone to back you up, you're asking for them to say something which supports your opinion.

But Eleanor has had a healthy winter too.

She's been tickety boo, which is an informal phrase, meaning everything's fine or in good order throughout the winter.

Many people try different techniques, like taking supplements or eating certain foods to boost their immune system, to improve their bodies natural defenses against disease.

Host of BBC Radio Force inside Health, james Gallagher ask stock to Margaret Mccartney whether some of these products are successful.

Okay, quick fire round. Margaret Echinacea.

No. Turmeric. No. Ginger shots. No.

This is a very, very good quiz.

What about the stuff you squirt it?

You know, is when you're at the beginning of an infection?

Interesting, but not any better than normal ceiling spray, just salt water.

In fact, according to Margaret, there isn't enough evidence that many popular health products can actually change the way your immune system works.

Another popular health trend in the UK is cold water swimming.

People who swim in cold water say it's good for their mental health, and they also believe it makes them less likely to get ill during the winter months.

But scientists aren't sure about the benefits of cold water swimming for the immune system yet.

As Professor John Tragoning explains to BBC radiofores inside health, the social element actually is really important.

It probably is beneficial to do.

You reduce stress. And cortisole dampens the immune system, so actually, if you'll stress them, maybe you are more prone to infection.

And that may be why that benefit of being with people, nice people that you like in nice places, is helping.

But I don't think it's unique to cold water swimming.

I think you could probably get it from dancing or singing or going for a run.

John says that cortisol, a chemical associated with stress, dampens the immune system.

Here, dampens means makes weaker. We also have a common expression dampens someone's spirits, which means to make them less enthusiastic about something.

John says that there is evidence that people who are stressed are more prone to infection.

If you're more prone to something, it's more likely to happen to you.

It could be that cold water swimming reduces stress, and so it helps people's immune systems work well.

But there are lots of other activities that could have the same effect and help people have fewer colds over winter.

Which reminds me of my question Georgie.

I asked, how many colds the average UK adult has a year?

And I said two to three.

And that is the correct answer.

So well done. Thank you. Okay, let's recap the vocabulary we've learned, starting with touch wood, which is an expression used often in speech to avoid bad luck.

Snuffles or sniffles are minor illnesses that affect your nose.

If you

ask someone to back you up, you want them to say something to support your opinion, the expression, tickety bo means fine and in good order.

If you dampen something, you make it weaker.

And the expression dampens someone's spirits, means you make them less enthusiastic about something, and if you're more prone to something, it's more likely to happen to you.
