With a gas fireplace, you can make sure your home is cozy and comfortable, while keeping your family and pets safe from allergens and other harmful substances.
But if you want to make your house even more livable, consider moving outdoors.
A new study by a group of researchers from the University of Illinois at Urbana-Champaign and the University at Buffalo, published in the Journal of Occupational and Environmental Medicine, has shown that the outdoor air you breathe is a major factor in the risk of asthma and other respiratory illnesses.
The findings were based on a survey of more than 5,000 U.S. adults conducted between 2001 and 2010.
They compared air quality in homes across the country, as well as air quality at the time of the survey, with indoor and outdoor air quality levels from different years.
In addition, the researchers also looked at how indoor and outdoor air quality affected the risk for asthma and related respiratory illnesses over the same period.
Researchers found that indoor air was the most hazardous to the lungs, followed by outdoor air.
The average indoor air quality was 11.7 micrograms per cubic meter of air, compared with 7.6 microgram, 6.3, 5.7 and 4.4 microgram levels, respectively, at the start of the study.
In other words, indoor air contains more harmful substances, and that can lead to respiratory problems.
Researchers also found that the average indoor CO2 level was 14.6 times higher than the national average for that time period, which translates to more than 30,000 people per year having an average indoor carbon dioxide level of more and an average outdoor CO2 of less than 20 microgram per cubic meters.
The researchers found that there were similar rates of asthma in outdoor and indoor environments, but they were not as high as in homes where the air quality had deteriorated.
This could be because outdoor air, which has more harmful constituents, has more time to settle, so the air can absorb CO2 and release it, according to the study authors.
The results also suggested that the risk could be higher for older adults, who tend to have lower air quality, and for those who smoke.
The authors did not address the possible benefits of using indoor gas fires, but it is possible that outdoor gas fires might be less toxic than indoor ones.
The study also noted that outdoor air was also more toxic to the brain, as it had been associated with an increased risk of depression, anxiety and other mental health problems.
The authors caution that the findings do not prove that indoor gas furnaces are bad for your health.
“The data are preliminary and may not translate into an effective policy for outdoor gas furnacing,” they wrote.
“Future studies are needed to further assess the effect of gas fireplace ventilation on indoor and non-indoor air quality and to determine the potential benefits of this technology on respiratory health and other health outcomes.”
