Air Pollution From Traffic Boosts Risk Of Heart Attack

Filed under: Health

Traffic jam

Next time you're in a traffic jam, it might not be a bad idea to huff and puff with your windows UP!

According to a study published in the British Medical Journal, breathing in the fumes from heavy traffic can boost your risk of heart attack for up to six hours.

Air pollution won't start causing heart attacks for just anyone, but could increase the chance of heart attacks in people already at risk.

To discover this revelation, researchers looked at health data from 79,288 people who have had a heart attack between 2003 and 2006 in the United Kingdom.

They then looked at traffic pollution data, including carbon monoxide and ozone levels, in different parts of the country.

After studying and comparing the data, it was determined that the likelihood of having a heart attack was the highest 6 hours after the people studied had been exposed to traffic fumes.

The connection is not entirely clear, but pollution can possibly thicken blood to make it more likely to clot. A co-funder of the study told news sources:

"We know that pollution can have a major effect on your heart health, possibly because it can 'thicken' the blood to make it more likely to clot, putting you at higher risk of a heart attack."

A similar study on the link between heart attacks and traffic suggests that although pollution may have an effect on the heart, it may also be stress!

The researcher presenting her findings during American Heart Association's 49th Annual Conference on Cardiovascular Disease, said:

"One potential factor could be the exhaust and air pollution coming from other cars, but we can't exclude the synergy between stress and air pollution that could tip the scale."

It's pretty hard to avoid traffic if you live anywhere near civilization, so the best way to avoid being at risk at ALL is to lead a healthy lifestyle with lots of exercise and good food!

Biking Saves Lives!

Biking saves lives

In Spain, at least!

Bike-sharing programs, which have popped up in cities around the world, will definitely save users money and kill a couple hundred more calories in their body, but recent research has found they will save lives too!

A study published in the British Medical Journal last week showed Barcelona's bike-sharing program not only saved 9,000 tons of pollution from carbon dioxide, but saved 12 lives per year due to the extra heart-healthy exercise.

Despite a VERY SMALL increase in deaths from bike-related traffic accidents (0.03 deaths) and air pollution (0.13), the overall health benefits of physical activity for the 180,000 cyclists using the program outweighed the risks.

We can't advocate bike-sharing programs enough and think they are wonderful!

We've said it before and we'll say it again, do not wait for a city-sponsored program to pop up near you to start benefiting from the healthy exercise this form of transportation has to offer!

The 10 Most Contaminated Beaches

Filed under: HealthBeach

Avalon beach Los Angeles

It's summertime and that means BEACH TIME! Yay!

Unfortunately, that also could mean exposure to contaminated water! Ewww!

Testing the Waters: A Guide to Water Quality at Vacation Beaches, a report released on Thursday, gathered data from 3,200 beaches across the country and found that beach closings had occurred 24,901 times in 2010 with 70% of those closings related to bacterial contamination in the water!

Yuck!

Contaminated water poses all sorts of risks including rashes, vomiting, bowel issues and serious infections.

Before you head to your favorite beach this summer, make sure it isn't on the “Top 10 Repeat Offenders” list for having dangerous water.

Check out the top ten most polluted beaches in America below!

Our Noise Kills Giant Squids

Filed under: Sad SadScience!Sea Creatures

So sad.

When giant squid washed up ashore along Spain's Asturias province in the early 2000s, the events occurred suspiciously close to when ships had used air guns to conduct low-frequency sound-pulse exercises in the region, Ocean Leadership reports.

While the noises were a possible cause for the squids' deaths, it was not confirmed until a recent study completed by a marine bioacoustician at Barcelona's Technical University of Catalonia and his team.

We have known for some time that whales and other marine mammals which rely on sound for communication and navigation have been harmed by the noise pollution in the ocean — either by not being able to hear, and therefore find, one another, or by being so blasted by loud sounds that they beach themselves or are killed by the trauma caused inside their skulls.

The study showed that among specimens of two species of squid, one species of octopus and one species of cuttelfish exposed to low-frequency sound for two hours, all showed signs of damage to their statocyst tissue, with the damage becoming worse the longer after exposure the animals lived.

25 Most Polluted Cities Have Cleaner Air Than Last Year!

Filed under: Environment

Los Angeles Smog

Good news! The U.S. Clean Air Act is working!

The "State of the Air 2011" report from the American Lung Association concluded that the air in the nation's 25 smoggiest cities has improved over the last year.

Lung Association President, Charles Connor, said in a statement:

"The progress the nation has made cleaning up coal-fired power plants, diesel emissions and other pollution sources has drastically cut dangerous pollution from the air we breathe."

While it looks like the air is getting cleaner, the report unfortunately still found 154.4 million people (over half the nation's population) live in areas where the air is filled with dangerous levels of ozone and particle pollution.

Yikes! That's not good!

The two cleanest cities were found to be Honolulu, Hawaii and Santa Fe, New Mexico. The most polluted was, you guessed it, El Lay, baby! Ha!

Darn.
