Prevent respiratory infections Any respiratory infection — even the common cold — can cause an acute exacerbation of COPD, so it is to your advantage to do whatever you can to avoid catching what's going around. Washing your hands frequently with soap and water can reduce your risk. Alcohol-based instant hand sanitizers can also help. As much as possible, stay several feet away from people who have colds or other respiratory infections that can be spread by sneezing or coughing.
In addition to having an annual flu shot and an immunization against pneumonia every five years (see "Immunizations"), you may also benefit from antiviral medications for preventing and treating influenza, such as zanamivir (Relenza), amantadine (Symmetrel), and rimantadine (Flumadine). These drugs are not substitutes for a flu shot, but they can offer added prevention. If you get the flu, they can help reduce the severity and duration of your illness. Exercise regularly If you are attending a pulmonary rehab program, you will also need to exercise at home on the days you don't attend sessions. It's especially important to find an exercise that you enjoy well enough to do almost every day. Aerobic exercises, which increase the heart rate and breathing rate, are most beneficial. If you don't like the treadmill, try tai chi, yoga, swimming, or walking around your neighborhood with a friend. Aim for at least 20 minutes a day on most days. Even if you aren't in a pulmonary rehabilitation program, regular exercise helps maintain strength in your arms and legs and prevent you from becoming easily tired during physical activities.
Do breathing exercises Another lesson from pulmonary rehabilitation that can easily become a part of your daily routine is pursed-lip breathing. This technique is valuable for helping you improve your breathing before and during physical activities. Before you start moving, inhale through your nose so deeply that your abdomen expands. Then, as you begin to move, exhale through your mouth with your lips pursed to slow down the airflow. Your exhalation should last twice as long as your inhalation. You will feel pressure in your windpipe and chest as you slowly breathe out. When you finish exhaling, rest for a moment, then inhale and start the process again. Breathing exercises can help keep you from feeling out of breath while going up and down stairs, walking in the mall, or otherwise exerting yourself. Use breathing exercises to pace yourself through physical activities. When climbing stairs, for example, you might inhale, then climb three steps as you exhale, rest, then inhale, climb three more steps as you exhale, and so on until you have reached the top of the stairs.
Eat and drink regularly Small meals are easier to digest and use less energy than large meals. If you have been avoiding eating because it makes you tired or out of breath, try having smaller, more frequent meals throughout the day instead of three large meals. In addition, drink plenty of water or other noncaffeinated, nonalcoholic beverages. This can help relieve congestion by thinning mucus, enabling you to cough it up more easily. There's no magic number of glasses you should drink daily; simply get into the habit of drinking regularly throughout the day.
Avoid lung irritants An important way to control your symptoms and prevent acute exacerbations is to keep your airways from becoming irritated. Many things can irritate the airways, especially exhaust fumes from your stove, smoke from your fireplace, dry air, and molds and mildew from water damage in your home. If you have allergies, try to avoid exposure to whatever causes them — pollen, pet dander, house dust, mold, and so on.
Here are some specific tips for avoiding irritants:
Use a humidifier when the air is very dry. Moisture in the air can reduce irritation by keeping your airways moist. A humidifier is especially helpful during the winter, when the air in your home may be dry. Change the water and clean the filter of your humidifier regularly to prevent buildup of mold and bacteria.
Ventilate your home. Good ventilation can reduce the amount of irritating dust and cooking exhaust in the air. Use an exhaust fan vented outdoors when cooking. Avoid using a fireplace or wood stove; wood smoke is a lung irritant. Unless you are allergic to pollen and other outdoor allergens, keep windows open when the weather is warm enough. Fresh air not only helps ventilate your home but can also raise the humidity level. Although it would seem that air purifiers may help, there is no clear evidence that they are beneficial for people with COPD.
Have furnaces and chimneys inspected. Making sure that furnaces are operating normally can reduce the amount of smoke and fumes they emit. Having chimneys cleaned can ensure that they vent smoke and exhaust effectively.
Avoid aerosol products. Just about any aerosol (other than medicine or oxygen therapy) can irritate your airways. That includes hairspray, perfume, deodorant, paint sprayers, and insecticides. Instead of aerosol products, use gel or liquid preparations; for deodorants, use roll-on or stick forms.
