  • A recent study looked at hypertension in 41,000 people in five different countries – Norway, Sweden, Denmark, Germany and Spain – for five to eight years
  • beginning in 2008, none of the participants reported having high blood pressure but by 2011, 6200 people reported having developed hypertension and started taking blood-pressure lowering drugs
  • The researchers found that for every five micrograms per cubic meter of particulate matter, hypertension increased by one-fifth or 22 percent in people living in the most polluted areas

People who live in areas with polluted air increase their risk for developing hypertension, a leading risk factor for the development of heart disease. Known as high blood pressure, the hypertension study is the largest of its kind to establish the deadly link.

It is part of the long-term “Europe Study of Cohorts for Air Pollution Effects,” known as ESCAPE, which focuses on health problems associated with pollution.

At the hypertension study, beginning in 2008, none of the participants reported having high blood pressure or taking medicine to control it. By 2011, 6,200 people reported having developed hypertension and started taking blood-pressure lowering drugs.

Most lived in urban areas where air pollution is highest.

Air pollution is measured in micrograms of particulate matter per cubic meter. The researchers found that for every five micrograms per cubic meter of particulate matter, hypertension increased by one-fifth or 22 percent in people living in the most polluted areas.

Epidemiologist Barbara Hoffmann, who works for the Center for Health and Society at Heinrich-Heine University in Germany and led the study, says many of these cases of high blood pressure could be prevented.

“So this is a very important result if you can see that something that you can actually change. I mean we can actually reduce air pollution, can have such an influence on such an important health outcome,” said Hoffman.

The findings were published in the European Heart Journal.

Hoffmann says researchers will now study areas of where pollution is low, looking at the health effects of cleaner air.

“But this is of course important in terms of regulation because you would like to regulate the air pollution down to a level where you do not see any (health) effects anymore. So, therefore it is really important to look at areas of low exposure and see how far down can you go until you do not see any effects anymore,” said Hoffman.

New Delhi, November 8, 2017 : Doctors have issued a health advisory asking people to avoid outdoor activities like jogging and cycling as high levels of air pollution in Delhi and NCR can cause chronic lung and heart diseases and also affect the health of expectant mothers.

The smog that has enveloped the region for the past two days can cause allergies or aggravate already existing allergies and decrease lung immunity, according to tips shared by Fortis Healthcare.

Vikas Maurya, senior consultant at Fortis, said preventive measures like avoiding outdoor physical activities like cycling, jogging or any other outdoor exercises should be taken.

He suggested that air purifying plants like Aloe Vera, Ivy and Spider Plant should be kept at home and in offices.

Fruits rich in Vitamin C, magnesium, omega fatty acids should be consumed more to fight any allergy or infection. “Have herbal ginger and tulsi tea in adequate quantity.”

The doctors said air pollution poses a major health risk and can cause stroke, heart disease, lung cancer, and chronic and acute respiratory diseases.

Islamabad, November 6, 2017 : Smog has enveloped much of Pakistan and neighboring India, causing highway accidents and respiratory problems, and forcing many residents to stay home, officials said Saturday.

Pakistani meteorologist Mohammad Hanif said the pollution, caused by dust, the burning of crops, and emissions from factories and brick kilns in Pakistan and neighboring India, was expected to linger until the middle of the month and contribute to smog- a combination of smoke and fog. He advised people to wear facemasks to protect themselves from respiratory ailments.

Mohammad Arshad, a highway police official, said at least 10 people were killed and 25 injured in road accidents linked to poor visibility in various parts of the Punjab province due to smog, since Monday. Authorities have advised people to limit road travel.

Average air pollution in Pakistan’s major cities is about four times higher than the World Health Organization limits.

Similar problems have been reported in the Indian capital, New Delhi, where air quality was rated “very poor” Saturday. Some private schools in New Delhi have suspended sports and outdoor activities.

India’s Supreme Court banned the sale of firecrackers in New Delhi ahead of last month’s Hindu Diwali festival to try to curb air pollution in the city notorious for smog. Though reports said air quality was better than last year, pollution levels in the capital hit 18 times the healthy limit the night after the festival, as many dodged the ban. (VOA)
