Here's some info for all those in Western Canada and the US, as they struggle to contain the ongoing wildfires. A newly published study shows exposure to PM2.5 (particulate matter less than 2.5 micrometres in diameter) was associated with an upswing in out-of-hospital heart attacks in men and ischemic heart disease (IHD) events in women.
The study shows the associations between cardiac arrest and IHD as a result of exposure to high levels of PM2.5
smoke for up to 2 days. The researchers also found that cardiac
arrests and IHD disproportionately affected men and women who were 65
years old and older.
The American Heart Association characterizes PM2.5 as a risk factor that contributes to cardiovascular disease's mortality and morbidity.
The researchers say more work needs to be done to explain the
differences of cardiovascular disease in men and women. Furthermore,
"improvements in the understanding of these priority areas is needed
so that effective and timely public-health strategies can be developed
and implemented to reduce the burden of disease during wildﬁre
events. This will have further implications for setting appropriate
air-quality standards, enhancing healthcare infrastructure, and
improving timely risk communication and health advice during wildﬁres."
...may also be something to consider when camping and being around a camp fire this summer.

Thanks for visiting! My goal here is to discuss the latest scientific research to separate the good from all that "guff" in nutritional sciences and all aspects of human health. Because the more you Know, well...the more you Know!
