MedWire News: Long-term exposure to ozone is associated with an increased risk of death from respiratory causes, researchers have found.\n\nA two-pollutant model in the study, published in the New England Journal of Medicine, showed that levels of fine particulate matter less than 2.5 µm in diameter (PM2.5) were associated with death from cardiovascular causes, whereas increased ozone concentrations were associated with an increased risk of death from cardiopulmonary causes.

Is sunshine more than just a home remedy for a cold? New research suggests it may be: In a study that will be published tomorrow, people with low levels of vitamin D - also known as the "sunshine vitamin" - were more likely to catch cold and flu than folks with adequate amounts. The effect of the vitamin was strongest in people with asthma and other lung diseases who are predisposed to respiratory infections.
