 Exactly, the wildfire smoke, because it contains teeny tiny particles that are called particulate matter, and they are small enough to enter the bloodstream, the heart, and the lungs when they are inhaled, and those little particles can raise the risk of dying from heart disease or lung disease or strokes. Fantastic. So that's a study that covers the chronic exposure to wildfire, not just short-term exposure to wildfire smoke, but long-term chronic exposure over time, and it's the first of its kind to do that.
