Wildfire smoke. What EXACTLY does it do to the human body?

First let’s take a look at what it is. Primarily smoke is made up of Particulate Matter (PM). That’s microscopic particles of 2.5 micrometers or less. To get some perspective, a human hair is 70 micrometers across. Add to that, carbon monoxide, carbon dioxide, nitrogen oxide, irritant volatile organic compounds (VOC’s for short) gases and […]

Childhood asthma linked to anxiety later on

There is increasing evidence linking childhood asthma to anxiety later on in life. Children with asthma are 2 to 3 times more likely to struggle with anxiety as adults.

Air pollution changes the structure of the heart

There has been lots of research in recent years on the dangers of air pollution and how it can lead to heart disease. We knew there was a link but we didn’t know why, until now. Scientists from the Queen Mary University in London found that exposure to nitrogen dioxide and fine particulate matter, also […]
