It is a well known fact that air pollution is extremely harmful to health. Now, a new study has also established a link between air pollution further increased stroke risk and later death. Research from Sun Yat-sen University School of Public Health in Guangzhou, China, published in neurologyPM 2.5 focuses on the negative health effects of granules, fine particulate matter (PM) less than 2.5 microns in diameter (about 30 times smaller than a human hair).
The research also included the study of nitrogen dioxide (NO2) and nitrogen oxide (NO) levels in polluted air and measured air pollutant level By their weight in micrograms – 1 millionth of a gram – per 1 cubic meter of air, expressed as micrograms/m3.
For every 5 µg/m3 increase in PM 2.5, the risk of a first stroke increases by 24, according to an observational study based on the UKBiobank analysis of health records of 3,18,752 people and several years of UKBiobank air pollution data. Gone. percent, and the risk of a first fatal stroke increased to 30 percent. The research identified 5,967 incident stroke patients, 2,985 post-stroke heart patients and 1,020 deaths.
the risk of cardiovascular mortality A “slight increase” has also been seen for people who have already had a stroke. This was especially true of NO2, which increased mortality by 0.04 percent, although this effect diminished over time, the study noted.
According to the Journal of the American Heart Association, Dr Amit Srivastava, Senior Consultant – Neurology, Dharamshila Narayan Superspecialty Hospital, said that the increase in air pollution is thought to account for 14 per cent of all stroke-related deaths. “Air pollution can also harm children’s cognitive abilities, increase the likelihood of cognitive decline in adults, and even cause depression,” he said. indianexpress.com,
Short-term exposure to air pollutants is closely related to higher rates of COPD (chronic obstructive pulmonary disease), cough, shortness of breath, wheezing, asthma, respiratory illness and hospitalization (a measure of morbidity), according to a review published in is related to. Frontiers in Public Health, while the long-term effects associated with air pollution are chronic asthma, pulmonary insufficiency, heart disease and cardiovascular mortality. The review also suggested that short-term exposure to air pollution was related to stroke among others.
emphasizing that the main cause of stroke is disability And the second leading cause of death in the world, Dr Sameer Arora, Senior Consultant, Neurology, Narayan Hospital Gurugram, said that high levels of air pollution are associated with an increased risk of infection from being healthy to stroke.
“Nitrogen oxide and nitrogen dioxide have been linked to an increased risk of stroke and mortality. Pollution is a major source of concern for public health, and is recognized as one of the leading causes mortality and disease. The danger posed by air pollution is determined by both the duration of exposure to the pollutant and its toxicity. indianexpress.com,
