Believe it or not, coughing is actually good for you. It's the body's way of eliminating the infection that causes bronchitis. So, instead of stifling a cough with an over-the-counter suppressant, help it along by using a warm- or cool-mist humidifier to add moisture to the air. (Take care to use and clean the humidifier according to the manufacturer's instructions.) The added humidity will help bring the sputum (matter that's coughed out of the body) up and out of the body. Standing in a steamy shower with the bathroom door closed, keeping a pan of water at a slow boil on the stove (never leave it unattended!), and using a tea kettle to shoot out warm, moist air can also help loosen and bring up phlegm. And if you have a few drops of peppermint or eucalyptus oil to add to the water, these can be quite soothing.
