The risk of exercise in a city full of pollution

Big city is always synonymous with high air pollution from vehicles or industry. Sports in the middle of the city that have air pollution, there are negative effects.
If someone regularly exercise in the area of air pollution will have an adverse impact on health, especially for people who have chronic lung disease, heart disease or diabetes.

When someone does a sport, even with a low intensity so it will breathe 10 times more than when resting.
In such conditions, people tend to inhale more deeply into the lungs and breathe through your mouth, so pass filtering in the nose.

These factors will improve body contact with pollutants, the combination of air pollution, and this exercise will be a potential risk.

Year-round exposure to air pollution or particulate matter — a mix of tiny specks of soot, dust and aerosols suspended in the air — has been linked to:

* Significant damage to the small airways of the lungs
* An increased risk of heart attacks and strokes in older women
* An increased risk of death from lung cancer and cardiovascular disease

Despite the potential health risks, don't use air pollution as a reason to skip exercise if you're otherwise healthy. To limit the effects of air pollution and exercise:

* Time your workouts carefully. Check local air pollution alerts and plan your outdoor workouts accordingly. Avoid outdoor physical activity when pollution levels are highest — in the midday or afternoon in many areas.
* Avoid congested streets. Pollution levels are likely to be highest within 50 feet (15 meters) of the road.
* Exercise indoors. Vary your routine with occasional indoor activities. Take a fitness class, check out a local gym or run laps on an indoor track.

If you have a chronic condition, share any concerns you may have about outdoor exercise with your doctor.
