As people spend more time inside during the COVID-19 outbreak, it’s important to recognize and reduce sources of pollution in your own home. Indoor air quality varies, but is often worse than outdoor air quality. However, you can improve the air quality in your home by reducing lung irritants generated indoors. Following some basic guidelines in your day-to-day routines can improve the health of those in your home who live with asthma and other lung diseases.
People are cooking at home more often during the COVID-19 outbreak. Cooking creates moisture, which feeds mold and mildew growth – a common trigger for those living with asthma. It also exposes you to pollutants like nitrogen dioxide, particularly from gas stoves. Nitrogen dioxide is known to worsen asthma and COPD symptoms. Using a stove fan that vents to the outside can reduce pollution from cooking by 75 percent. Opening windows while cooking can also help keep the air in your home clean.
With people home more often, your bathroom and shower may be used more. Moisture from showers can lead to mold and mildew growth, which may affect the lungs of people living with asthma. Use the bathroom fan to vent extra moisture to the outside. If you haven’t checked your fan lately, now is a good time. Remove any dust and dirt from the fan grill to keep it working properly. If your bathroom doesn’t have a fan, open a window if possible.
Regularly cleaning surfaces in your home is a good practice, and can also help prevent the spread of the COVID-19 virus. Taking some precautions when cleaning can help reduce the amount of indoor pollution created. If you are cleaning with chemical solutions, try to open windows vent fumes from your space. Additionally, you should never combine ammonia and chlorine bleach cleaners. This can produce a toxic gas which could be dangerous, and especially those who live with asthma. If possible, use a vacuum cleaner, which limits dust levels in the air. The U.S. Centers for Disease Control (CDC) also recommends removing your shoes when you enter your home, as they can bring in additional dirt, dust and germs.
Other Daily Activities
A number of other daily activities and products can worsen indoor air quality. Nail polish, candles and paint are just a few examples of products that can affect lungs, especially those of people living with lung disease. Open windows to circulate air in your home, or use these products outside if possible to protect those in your home living with asthma.
Anyone in your home who smokes should do so outside, as smoke and vapor from tobacco and e-cigarette products can be especially irritating to the lungs of someone living with asthma. Also, if you live in multi-unit housing, be aware that some of your neighbors may be struggling at this time and their conditions could worsen from second hand smoke. If you are thinking about quitting, there are a number of resources to help you here.
Reduced activity outside the home has generally helped improve outdoor air quality. However, if you live near pollution sources like industrial facilities or major roadways, you may still risk contact with potentially harmful air pollution. Those living with asthma may also be sensitive to outdoor allergies. In these situations, opening windows is still a good option to ventilate your home. However, consider limiting the amount of time you leave them open. If opening windows is not possible, air filters may be another option to keep good air quality in your home. You should only use devices certified by a trusted source, as some filters use ionizing technology which can produce harmful gas inside your home.
