The Alaskan Summer of 2019 will go down in the books certainly as a record hot one.  It will also be remembered as one peppered with constant, long-lasting wildfires producing so much smoke it blocked out our beautiful scenery and made it difficult for many Alaskans to breathe outside.

The smoke from wildfires can be dangerous to inhale, especially if you have respiratory troubles.

The winds allow smoke from multiple wildfires to spread across portions of the Kenai Peninsula, Anchorage Bowl, and Mat-Su Valleys. The smoke has reduced visibility to as low as one mile at times, and possibly less than one mile near active fires.

Persons with respiratory problems are having difficulty breathing when outside. Wildfire smoke is a mixture of gas and tiny bits of matter, called particulate matter.

Alaska's Department of Environmental Conservation is advising people with respiratory illness or heart disease, the elderly and children, to avoid exposure to Poor air quality makes breathing and sleeping difficult.smoke. When in areas of smoke, their advice is to avoid outdoor activities or physical exertion.

Wildfires can often make symptoms of OSA worse, so it’s important to avoid breathing in smoky air as much as possible. While breathing in smoky air isn’t good for anyone, it can be particularly harmful to people with pre-existing lung conditions and obstructive sleep apnea. 

Consultants are now studying the impact of wildfires and the particulate matter that they leave behind, like soot, char, and ash. So even after a fire has been contained, you and your family should be aware that these pollutants may have an impact on how easily you can breathe when you go outside.


How does wildfire smoke affect your CPAP?

Living with sleep apnea in an area that is prone to evacuation orders because of wildfires means that you need to heed a specific warning: If you need to evacuate, make sure to go somewhere where you can treat your sleep apnea.

Sleep apnea equipment needs a reliable source of power, so if you need to evacuate your home, make sure you can get to a place that can provide power for your CPAP machine. Studies have shown that getting good and consistent sleep during times of emergency is particularly important for people with chronic health conditions.

This may involve some planning ahead and careful attention to the forecast. If it looks like conditions are worsening, it may make sense to leave early and get somewhere with reliable power to ensure that you can continue to treat your sleep apnea even when you are not at home.

A good night’s sleep and air pollution

In a recent study published in the Annuals of the American Thoracic Society, researchers looked at the link between obstructive sleep apnea and air pollutants.

The authors of the study found that people who lived in areas with higher amounts of these two types of pollution were more likely to have obstructive sleep apnea.

cpap-filtersSleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts during sleep. Obstructive sleep apnea is the more common type. It occurs when the throat closes and blocks the flow of air.

In the study, the link between air pollution and sleep apnea still remained even after researchers took into account other factors that could affect the results, such as body mass index, high blood pressure, diabetes, smoking, and family income.

Polluted air can make it difficult for anyone being treated for sleep apnea to breathe easily if they are not using their CPAP machine properly.

On a typical, clean air day in Alaska, the recommendation for replacing your CPAP filters is on a monthly basis.

However, more frequent changes of the filter might be in order if your air is especially polluted, such as during forest fire season or when it is especially dusty.  You might also consider changing filters after you catch a cold or when you start to smell odors in your mask. 

Filters are generally at the back of the machine over the air intake.  They are often gray or white in color.  Typically  CPAP filters are covered by insurances at a frequency of two disposable filters per month.

Many factors contribute to sleep apnea. These would need to be considered in future studies — such as noise and light pollution, different types of sleep environments, stressors and shape of the airway.

Research shows that air pollutants can cause some upper airway swelling and irritation in people and animals.

This swelling could worsen sleep apnea, depending on where it’s located and how severe.  Make sure you know what it is like outside by checking the Department of Environmental Conservation link regularly to get the most up-to-date information like the diagram below.

How Can Alaska Sleep Clinic Help?

CPAP filters help to clean the air generated by the CPAP machine. In general, fine filters should be replaced every four weeks. People living in homes with smoke seeping in from these Alaska wildfires need to replace CPAP filters more frequently

Alaska Sleep Clinic wants to make this task as easy as possible.  Right now, we are offering a FREE set of filters for your CPAP machine; so you can breathe a little easier until the wildfire season passes.

Contact Alaska Sleep Clinic today to find out how you can get a set of filters for FREE.
