Air pollution causes brain aging

New research shows the level of air pollution in towns and cities makes brain aging about 3 years.

Scientists say that exposure to large amounts of air pollution can lead to a 50-fold reduction in brain power.

Previous research has also shown a link between polluted air and cardiovascular and respiratory problems.

In a study of nearly 15,000 elderly people, researchers at the National Academy of Aging showed that air particles can be an important environmental factor in impaired thinking.

It is estimated that air pollution reduces the lifespan of everyone in the UK by an average of 7-8 months, and can affect the heart and lungs.

Dr Jennifer Ailshire, from the Andrus Center for Geriatric Medicine at the University of Southern California, said: 'As a result of the decline in health and age, the elderly are vulnerable to exposure to contaminated air. .

Scientists are studying the effects of air pollutants called PM2.5 on the health of participants, by vehicle emissions, gas boilers and heavy industry.

Professor Frank Kelly, professor of environmental health at Cardiff University, said: "The average amount of this contaminant in London is about 13 to 15 micrograms per cubic meter, while in some shallow areas The village can be as low as 3-4 micrograms. '

Research has also shown that living in a place where it is not clean, your brain will be much healthier than living in areas where air is contaminated.

This is a study that shows that the air quality that we breathe daily not only affects the heart and lungs, but also affects the brain.

New research is presented at the Gerontological Society of America (GSA), the 65th annual scientific conference in San Diego.

Simon Birkett, founder and director of the Clean Air Association in London, said: 'This study is a reminder that the health effects of air pollution are much greater than the effects. Short term of air pollution that we can see in the foggy period of 1952.

The government has started warning people and giving them advice to protect and reduce pollution for themselves and everyone around them. '

Last year, a study found that high levels of air pollution can increase the risk of heart attack up to six hours after exposure.

Dr. Krishnan Bhaskaran, from London School of Hygiene and Tropical Medicine, and colleagues used data in the UK National Archives on air quality to investigate the extent of specific pollutants in the atmosphere of the time and place of the victim's heart attack.
