New research has shown that breathing dirty air can lead to a surge in stress hormones, which may help explain why it takes a long time
Long-term exposure to pollution is associated with heart disease, stroke, diabetes and a shorter life span. Dr.
Haidong Kan and colleagues from Fudan University in Shanghai, China have studied the impact of particulate matter on health (PM)
Small particles are less than 2.
The diameter obtained from industrial sources is 5 microns and can be inhaled and stranded in the lungs.
Although PM levels in North America have declined in recent years, global PM levels are rising.
\"This study adds new evidence to how exposure to PM can affect our bodies, which may (ultimately)
It can lead to higher cardiovascular risk . \"
Kan said in an interview with Reuters reporter.
\"Our results may indicate that particulate matter may affect the human body in more ways than we currently know.
Therefore, it is increasingly necessary to understand the importance of reducing PM exposure.
\"The new study, published in the journal Circulation, includes 55 healthy Shanghai college students, whose pollution levels are at moderate levels compared to other Chinese cities, according to the doctorKan.
He and his colleagues put work or non-
Use the air purifier in each student\'s dormitory and place it for nine days. After a 12-
During the day of removing the filter, the researchers did another 9-
Daily test: students in the original function-
Non-filter group
Working filter, and filter that didn\'t work
The Filter group gets a valid Filter.
At the end of every nine
During the day, the researchers tested the levels of multiple small molecules in the student\'s blood and urine as an indication of their exposure to PM.
With air pollution, students\' levels of stress hormones, cortical hormones, adrenaline and adrenaline have risen, as have blood sugar, amino acids, fatty acids and lipids.
Increased exposure to PM is also associated with elevated blood pressure, adverse reactions to insulin, and molecular stress markers in body tissues
All of this can increase the risk of heart disease, diabetes and other problems over time.
Air purification reduced the number of PM students exposed to air by half, from 53 micrograms per cubic meter to 24 micrograms.
3 micrograms per cubic meter-but this is still much higher than the who\'s 10 micrograms per cubic meter of air quality guidelines. Dr. Robert D.

Writing an editorial accompanying the study, emailed Reuters Health Channel, the pressure responses caused by these small contaminated particles \"are larger and more diverse than previously known.
He added: \"Simple actions taken at the individual level, including the use of air purifiers with HEPA filters, can significantly reduce exposure and help mitigate (PM)
A few days later
Looking forward to the future, he said, these findings \"help lay the foundation for what we think is urgently needed now --
Clinical trial evidence for individualslevel actions (
Air purifier, N95 respirator)
It can actually reduce cardiovascular events and mortality in high-risk patients living in heavily polluted countries.
\"This evidence
Brooke said: \"There is a need for evidence-based help to provide clinical advice to millions of people with heart disease who live in areas with poor air quality and are unlikely to improve significantly over the next few decades.
\"Air pollution poses a global threat to the health of all people living around the world,\" he added . \".
\"We are all in danger of air pollution, at least partly responsible.
It\'s time to push for cleaner \"green\" energy and transportation --
For our own benefit and for the benefit of others on earth. ” SOURCE: bit.
