Study: Pollution wipes out the benefits of exercising

You might think going for a power walk on your lunch break is a good way to get in some exercise, but a new study found that if your walk is through busy city streets, it may not be benefiting your health at all.

According to Researchers from the Imperial College London, toxic air in built-up city centers prevents the positive effects on the lungs and heart which are usually gained from exercise. 

Even though the study was conducted on people over 60 years old, the results could apply to people of other ages.

One-hundred and nineteen people were asked to take a two-hour stroll through Hyde Park, a very famous park in London and also on Oxford Street, a very busy shopping area in the same city.

People who took a stroll in the park saw improvement in lung capacity within an hour. However, those who strolled through the busy street barely registered any improvement at all, as well as seeing little to no increase in blood flow usually associated with exercise.

So if you’re going for a walk, opt for a greener area!

Many of these photos show life in America at the time, but several also document concerning environmental issues.

David Shanklin, pictured here at age 19, lived in a coal-company town near Sunbright, West Virginia. Shanklin's father was killed in the mines in 1954, and though Shanklin wanted to become a miner, his mother didn't want him to.

Smog, seen here obscuring the George Washington Bridge in New York, was a far bigger problem.

Factories burned discarded automobile batteries in the 1970s, releasing pollutants into the air. Current regulations require the batteries to be recycled without contaminating the surrounding area, though some are exported.

Mary Workman of Steubenville, Ohio, holds a jar of undrinkable water from her well in this photo. She filed a lawsuit against a coal company, accusing it of polluting her water. The EPA now uses the Clean Water Act to prevent companies from contaminating drinking water.

An abandoned car sits in Jamaica Bay in New York City in 1973. Landfills and auto salvage yards fall under the EPA's regulations now, though improper disposal still occurs.

Air pollution that can cause respiratory illness and other health problems was far less regulated before the EPA was founded. The EPA estimated that the Clean Air Act, which regulates pollution from industries, prevented more than 160,000 early deaths, 130,000 heart attacks, and millions of cases of respiratory illness in 2010 alone.

Coal-mining companies were bigger polluters in the 1970s as well. President Donald Trump has pledged an industry resurgence and recently nominated a coal lobbyist to be Pruitt's second-in-command at the EPA.

Pollution in industrial cities like Cleveland, Ohio, was particularly severe.

This photo shows a burning barge on the Ohio River in May 1972. A fire on the Cuyahoga River in 1969 (the 13th time that river had caught fire) helped to inspire the creation of the EPA.

The agency helps regulate cleanups in particularly polluted sites. The Twin Towers are visible behind the trash heap in this image.

Trash and old tires littered the Baltimore Inner Harbor in 1973. The EPA regulates waste disposal now, including in coastal locations. EPA cleanups in the harbor over the years have targeted dangerous chemicals.

All kinds of trash used to be dumped outside New York City, like this car at Breezy Point, south of Jamaica Bay. The EPA helped institute regulations for how the city disposed of trash to prevent dumping in the Atlantic.

Without regulation, more companies and manufacturers would be able to dump pollutants into waters and the air we breathe.
