    Wildfire Smoke Is Especially Toxic to Lungs, Study Shows

    Fine particles in wildfire smoke pose a far greater threat to the lungs than similar particles in vehicle exhaust and other types of air pollution, researchers report.

    These fine particles -- called PM2.5 -- have a diameter about 1/20th the size of a human hair and can get into the respiratory tract, enter the bloodstream and damage key organs.

    PM2.5 is the main component of wildfir...

    Snow Shoveling, Slips on Ice Bring Cold Weather Dangers

    Clearing away snow can be hazardous to your health, experts warn.

    Shoveling snow causes 100 deaths a year in the United States, and injuries due to improper use of snowblowers are common.
