The invisible killer in all our lives

We are surrounded by invisible murderer. One so common we have just noticed to shorten our lives.

It is causing heart attacks, diabetes type 2 and I study now as well as dementia.

What do you think it could be?

The answer is noise – and their impact in the human body goes away from the feeling of harm.

“It’s a public health crisis, we have a huge number of people exposed in their everyday life ,, says Prop Charlock, from San Coupége’s, University.

It’s just a crisis that I don’t speak.

So I investigate when the sound becomes dangerous, hit people whose health suffers and see if there is some way to overcome the world.

I started to meet the CLARK bark in a silent silent silent son. We are going to see how my body reacts to the sound and I have been kidding with a device that looks like a chunky smartwatch.

Is to measure my heart arrow and how much their skin sweatshirts.

You can join even if you have any headphones. Think of how these five sounds feel you.

The one that really finds the grateful is the traffic noise from Dhaka, Bangladesh, who has the family title in the world. I immediately feel that I am in a ginord, stressful traffic traffic.

And the sensors will pick up my agitation – my heart fee pull and my skin sweat again.

“It’s really a good evidence that the traffic noise affects your heart’s health,” says Promic profile, like the next sound is prepared.

Only young people of game play has a calming effect on my body. Dogs abab and the neighbor’s party in the first hours lead to a negative response.

But why are the sound of changing my body?

“You have an emotional response to the sound,” says Profit’s profit.

The sound is detected by ear and passed on the brain and region – the amigdala – make emotional rating.

This is a part of the body’s body’s response that has evolved to help react rapidly to sounds as a predator who fails through the balls.

“So your heart arrow, your nervous system begins to pate in the release the stress,” Prophers tell me.

All this is good in an emergency, but in the time it begins to cause harm.

“If you exposed for many years, reacts your body, increase your risk of developing things, the heart attacks, tight 2 diabetes.

Insidiously, this happens as well as you sleep soon. You may think that you suit you to the noise. I think I did when I live in a rent near an airport. But biology tells a different story.

“Never turn your ears; when you are sleeping, you are always listening to. Thus the answers, as your charge, what happens while I am adding the profit of profit.

The sound of sound is undesirable. The transport – trial, trains and works – are a great source, but so so are the sounds of us then possessed for a great time. A big person’s great holiday is the insufferable noise.

I meet coco on his floor side in the real historical of Barcelona grazing, Spain.

There is a lot of fantastic lemons tied to his door, its refrigerator contains a tortilla cooked by another and offer me a third near the patrous.

By the balcony you can see the city cathedral, the famigasy sag. It is easy to see you coco is in love with you to live there but it comes in a big price and she thinks it will be forced to leave.

“It’s extremely noisy … it’s a 24-hour noise,” she tells me about me. There is a dog park to walk his poo whispers to 2, 4, 5am “and the culmen is used for the whole birthday’s concerts.

She goes out his phone and plays the music records to be burned so strong makes glass in their vibrate windows.

Their house should be shelter from the stress of work, but the noio “brings frustration, I feel like crying.”

She was “hospitalized twice with the chest pain” and “absolutely” think the noise is causing the stress, that harms their health. “There is a physical change I feel, needs something to your body, sich,” she says.

To Barcelona are ignibuted 300 hearts of hearts and 30 deatons a year only the sound of traffic, according to the departments, which he revised the evidence of health.

In the whole Europe The sound is related to 12,000 deaths of death a year as a millions of severely disturbed sleep and even serious harassment that may impact mental health.

I meet the doctor to a coffee that is separated by one of the most affected roads of Barcelona from a small park. My sounds sound tells the sound from far away traffic is just more than 60 decibels here.

We can easily chatter on the noisy without lifting our voice, but this is already a miscellaneous volume.

The crucial number for the heart health is 53 decibels, tells me, and the highest goes to bigger health risks.

“That 53 means we need to be in a rather quiet environment,” says the doctor.

And this is right in day we need the lower levels too for sleep. “To the night we need the quiet”, he says.

Even if it’s not just about the volume, which disruptive the sound is and how much control you have completed to affect our emotional response to the nock.

Dr. Dre arisen the health impact is “at the level of air pollution”, but it is very hard to understand.

“We’ve been using that chemical chites can affect the health and they don’t understand that a physical factor, affect our health oil our health -” she says.

A strong holiday can be the fun that makes life worth living and another aisle intolerable.

Traffic sound has the greatest impact on health because their people are exposed to her. But traffic is also the sound of going to work, doing the purchase and taking children to school. The cutty noise means asking people to live their lives differently – which creates the problems of yourself.

Dr Natalie Mugener, from the Barcelona institute for global health, bring me for a walk around the center of the city. We started on a busy road – my sounds of sounds in more than 80 decibels – and us to go to a quiet avenue to the tree where the rumor is down the 1950s.

But there is something different on this road – it had been an imposed road but the space was given to peders, coffee and gardens. I can see the ghost of an old cross roads from the form of the floweryness. Vehicles can also fall here, just slowly.

Remember the laboratory, we found that some sound can soothe the body.

“It is not completely silent but it’s a different perception of sound and noise,” I am doctor to say. My heart frozy is falling and i stopped sweat.

The initial plan was to create more than 500 zones as this is sent “Superbloks” – Pedestrian ares created for groups of town blocks together.

Dr. Mueller did the research Planning a 5-10% reduction in the noise in the city, which would preview the death “150 women” of sound each year. And this would be “only the tip of the iceberg” of the health benefits.

But in reality only six superborn were ever built. The city board refused to comment.

The dangers of the sound is about to grow. The urbanization is getting more people in noisy city.

Dhaka, Bangladesh, it’s one of the world’s faster growth in the world. This brought more traffic and given the city a coloring cooked of honor.

During about 10 minutes each day, has the intersection of a pair of a pair of a large yellow jail that onkan their strong horns to cause massive annoyance.

Took the mission after his daughter was born. “I want to stop all onokate not only Dhaka, but of Bangladesh,” he says.

“If you see the birds or trees oi rivers, none makes noises without human, so that man are responsible.”

But here are the beginners even political action. Syda Rizwana Hasan, what is the environment recommendation and the Minister of Bangladesh, he told her “very worried” on the impacts of health.

There is a crackdown on Honking CASS to get rumor levels – with a conscious campaign and narrow stretch of existing laws.

Said, “It is impossible to get in a year not, but I guess it is possible to be as well as you feel better when you will also change the habit” not even change “

The sound solutions can be difficult, complicated and challenge to solve.
