Air Pollution Increases COVID-19 Risk: 6 Ways Protect Yourself


If you were here in 2003, you likely remember the SARS epidemic. How could any of us forget watching that coronavirus sweep through Ontario and the nation?

As then, so now - only this time the coronavirus is spreading faster… well, you've read the news headlines. You know.

What you may not know is this: the 2003 SARS epidemic taught us a lot. While it may seem as if we’ve been caught unprepared for SARS-CoV-2, aka COVID-19, scientists have actually been studying the 2003 epidemic all along, searching for clues, links, anything at all that we can use when (not if) it happened again.

Now it has happened again. So what can science share to help us fight back?

Here is what we now know: air pollution makes the threat worse.

Exposure to polluted air makes healthy people sicker once the virus crosses their path. If air quality improves, cases lessen and symptoms become milder.

You can't clean up the air outdoors (although astronauts aboard the International Space Station have confirmed the air is visibly clearing in areas where people are actively sheltering in place).

But you can clean up your indoor air.

Even if you are sick or someone you are caring for is ill, cleaning up your indoor air now can potentially help you recover faster and stay well.

Learn what you can do now to clean up your indoor air and help your immune system help you stay well.

1. Take smoking and vaping outside

Obviously, giving up smoking and vaping would deliver the best results.

But for the sake of staying realistic, at least do your lungs and loved ones a service by taking these habits as far away from your indoor airspace as possible.

After all, the place where this new coronavirus is hitting the hardest is in the lungs. Pneumonia as a secondary infection is currently the leading cause of COVID-19 fatalities.

2. Cease all use of air fresheners, fragrances and perfumes

We realize it can be challenging to give up your favorite scents in these challenging times. But you don't have to give them up entirely! You just have to change the source.

The vast majority of commercially sold air "fresheners" and so many fragranced personal care products get their wonderful scents via toxic combinations of unpronounceable chemicals.

These chemicals are extremely irritating to the sensitive tissues of your respiratory system and lungs.

By far a better way to enjoy the scents you love is through natural citrus, spices, fresh flowers, essential oils and natural teas. Have you ever tried boiling water on the stove and dropping in an apple spice tea bag or a fresh clove stick? Heaven.

Even better, many essential oils actually have immune-protective properties.

Ginger, sweet marjoram, cinnamon, lavender, lemon, cypress, eucalyptus and others have been studied for their abilities to boost T-cell counts in the body's immune system (T-cells are the "killer" cells that fight off disease).

3. Keep your furnace air filter (and any other air filters) clean

The cleaner your furnace air filter is, the more toxins it can trap. The same holds true if you have an air filter in your vacuum cleaner or are using any indoor air quality aids like humidifiers, dehumidifiers or HEPA filtration systems.

If your stove has an exhaust vent, now is the perfect time to check and clean that as well. And make sure you give your clothes dryer a good cleaning and check the exhaust vent to clear away any built up dust.

Basically, if it is in or near your house and has an air filter, make sure it is cleaned regularly and thoroughly (or replaced on schedule) according to the manufacturer's instructions.

4. Tend to your HVAC coils, air registers, fans and exhaust vents

Isn't it amazing how quickly your ceiling fans can collect dust? The same holds true for your air registers and exhaust vents and HVAC coils. Dust just seems to gravitate to these places, where it is largely unseen but definitely felt.

Your lungs are also air filters and you don't want to make their job harder by letting dust build up inside your home. The most effective method of dusting is to use a wet cloth to actively trap the dust particles. The cloth can then be rinsed and washed. 

5. Cook outside or use slow cookers rather than your stove

As much as we all love to eat yummy food, cooking on a wood or gas stove releases a host of volatile organic compounds (VOCs) into your indoor air. Even if your gas stove has a hood (vent) you can use while you are cooking, you can't avoid breathing in some of those chemicals.

It may not sound wonderful to grill outdoors in the winter, but you would be doing your lungs a favor. Another option is to open up your windows and run a ceiling or floor fan while you are cooking indoors to exhaust any toxins to the outdoors as quickly as possible.

Another option to reduce VOCs inside your home is to use an electric slow cooker or your oven rather than cooking on the stove. Even if you don't make this change permanently, it sure can't hurt to do it temporarily until the COVID-19 threat lessens.

6. Increase your indoor air humidity

There is a direct link between increased humidity and increased immune response to cold, flu and coronavirus germs. So right now we are offering $50 off the installation of a whole home humidification system.

Other ways to temporarily increase indoor air humidity (aim for 50 to 60 percent, especially if your household includes elderly or immuno-compromised family members) is to run a portable humidifier, leave doors open after you shower or bathe or add more houseplants (which also have an air purifying effect on their own).

Bad Air Makes Coronavirus Threat Worse: What to Do Now to Limit Your Risk

It is not news that smoking is bad for your health. Similarly, it would be hard to find anyone today who doesn't understand the link between air pollution and disease.

But as we watch the rapid-fire spread of coronavirus around the world, it is definitely time for a refresher course in why bad air is so dangerous. In fact, when you factor in COVID-19, it now appears that bad air can literally be deadly.

In this timely post, find out what the link is between bad air and coronavirus and how you can take action to limit your risk.

The Link Between Bad Air and COVID-19

To understand the link between bad air and COVID-19, you first need to understand what makes this new novel coronavirus so deadly.

The major symptoms of COVID-19 are as follows:

  • coughing

  • shortness of breath

  • fever

  • pneumonia (in both lungs)

  • secondary infection (lungs, kidneys)

The moment the coronavirus gets past the respiratory gatekeepers, it heads straight for the lungs.

The healthier your lungs are if and when you are infected with coronavirus, the higher the likelihood your body will be able to fight off COVID-19.

If your lungs are already damaged, scarred or infected with another respiratory illness, you are going to have a much harder time fighting COVID-19.

This is not to say that if you smoke now or have smoked in the past you are automatically going to get the coronavirus. But it is a call to actively protect your lung health in every way you can, which includes cleaning up your indoor air.

What Science Has to Say About Combustion, Smoking and COVID-19 Cases

A recent Washington Post article outlined a scary new hypothesis that is just now coming together in the international health community.

The researchers are using three measures to identify the group of people who are at highest risk of contracting COVID-19:

  • looking at data from the 2003 SARS outbreak

  • looking at data from the 2014 MERS outbreak

  • identifying the areas in China that have been hardest hit by COVID-19

By searching for any association between patients from each outbreak, the researchers have discovered that smokers and people living in areas with extremely poor air quality were uniformly more likely to become infected.

This Is Your Lungs on Coronavirus

Your lungs do a lot more for you than just inhale and exhale air. There are tiny cells inside your lungs called alveolar macrophages.

These cells are like tiny air purifiers and filters. Their job is to make sure any bacteria, microbial particulates and other germs that come into your lungs in the air you breathe don't make it any further into your body.

But if your alveolar macrophages are already working overtime filtering out volatile organic compounds, combustion byproducts and inorganic carbon particulates, they may already be too damaged to mount a good defence.

Even if your macrophages are still in basically good working order, they will not be as readily available to fight off COVID-19 if you are breathing in toxic air with every breath you take.

Clean Up Your Air Supply to Help Your Lungs Fight Coronavirus

If you smoke or vape, now is definitely the right time to cross that habit off your list - and not just for your own safety and health, but also for your family's well-being.

But what can you do if you live in a geographic area where the air just isn't that great? You can't just up and move.

Luckily, modern technology has given us several indoor air quality aids that both the Centers for Disease Control (CDC) and ASHRAE (the American Society of Heating, Refrigerating and Air Conditioning Engineers) endorse as aids to fight coronavirus transmission.

The CDC and ASHRAE are recommending three specific methods for cleaning the air to limit the spread of coronavirus:

  • ventilation

  • filtration

  • UV purification

Using Ventilation, Filtration and UV Purification to Clean the Air

Ventilation, filtration and UV purification have always been key components of maintaining indoor air quality.

However, they are more important now than they have ever been, as our air quality gets worse and coronavirus continues to spread.

Ventilation: how it works

Outdoors, ventilation happens naturally. But indoors, the only way ventilation can occur is through natural cracks or when you open a door or window.

heat recovery ventilator is literally a set of mechanical lungs for your home or workplace.

Just like your body's lungs, a heat recovery ventilator breathes in fresh air through one channel and breathes out stale air through a separate channel.

This process keeps stale air from contaminating fresh air and removes toxins permanently.

Filtration: how it works

A filter is a device that removes unwelcome solid particles from the air. These particles may be cigarette ash, pollen, dust mites, pet dander or coronavirus germs.

But since coronavirus germs in particular can be quite tiny, not just any filter will do to combat the threat of COVID-19.

You need a special kind of filter called a HEPA (high efficiency particulate air) filter. A HEPA air filter can trap and remove toxins as small as 1/100th the size of a single hair on your head.

UV purification: how it works

Outdoors, the sun produces very strong light bands called ultraviolet light. UV light is the most powerful purifier on the planet.

The only way to bring this type of purifying power indoors is through a UV air purifier.

This type of purifier produces synthetic UV light that neutralizes any organic threats, including coronavirus germs, by changing their molecular structure.

Humidity, Heat and Light: The Power Trio That Fights Coronavirus

microscopic coronavirus

If you want a coronavirus germ to survive a long time, lower the temperature and dry out the air, says a new research study.

Obviously, what we want is exactly the opposite! We want to kill those germs as quickly as possible and make sure they stay gone.

While this study is eye-opening in terms of specifically studying the life cycle of the new novel coronavirus, SARS-CoV-2, it isn't actually new knowledge.

After all, it is the same cold, dry air that gives winter its nickname of "cold and flu season."

As we get more and more calls from worried customers who want to upgrade their indoor air quality right now, we feel it is vital to help you understand exactly which indoor air quality tips and aids actually work to protect you and your family.

Humidity, heat and light are three of them. Read on to learn more.

Humidity, Heat, Light and Coronavirus

Did you know that the term "coronavirus" is not specific to this new virus everyone is so worried about right now?

If you read last week's blog post here, you already know that this new (novel) coronavirus is actually a close relative of the SARS virus that plagued Canada back in 2003.

What you may not yet know is that both that SARS virus and this new one, which is being called SARS-CoV-2, are also relatives of the common cold and flu!

Yes, you read that right - the very same family of germs is responsible for our reliable winter cold and flu outbreak.

The reason more people catch colds and the flu in the winter season boils down to these two facts:

  1. Cold, dry air.

  2. Short days with little sunlight.

What is the link between increased illness, dry and cold air and less sunlight?

Cold, dry air lowers immune system function

When it gets cold and dry outside, it also gets colder and drier inside your body.

Your respiratory and body tissues dry out. The mucus required to trap suspected pathogens, toxins, bacteria and viral germs is not as plentiful. So the germs can rapidly gain a foothold and spread throughout your body.

Less sunlight means less air purification

Ultraviolet light is the most powerful purification agent we have. With less light, airborne toxins and viral matter can proliferate and spread at a faster rate.

A 2011 study proved that as the temperature rises and humidity increases, what is called SARS virus "viability," or ability to stay alive to spread, is drastically decreased.

This is a very good thing and it is exactly what we need!

So now let's take a closer look at this power trio of humidity, heat and ultraviolet light and how to use each to fight coronavirus.

Heat and Coronavirus

You now know that heat can potentially be a powerful ally in the fight against coronavirus.

One recent survey of 23 different research studies revealed that once a coronavirus germ lands on a metal, plastic or glass surface, it may survive anywhere from two hours to nine days.

That is a pretty broad window of time!

What increases the virus's chances of survival? Landing on a surface kept in a dry, temperature-controlled space.

In various research studies, scientists learned that coronavirus survives for long periods of time in temperatures of 20°C to 30°C (68°F to 86°F) as long as the air is very dry.

However, when the temperature is increased to above 30°C (86°F), the survival rate drops. When the temperature is increased to 56°C (132°F), the virus is inactivated within 15 minutes or less.

When air temperature is increased while humidity also is increased, the greatest rate of virus die-off is produced.

Humidity and Coronavirus

At very low levels of humidity, such as what Canada's long, dark winter season often produces, coronavirus can survive quite well for extended periods of time.

At less than 30 percent humidity, the new coronavirus is well able to survive for many days either in the air or on a surface.

But when the humidity reaches 50 percent or higher, and is combined with an increase in heat, the coronavirus does not cope well and dies off much more quickly.

Light and Coronavirus

As we talked about in last week's blog post, ultraviolet light from the sun is still the most powerful sanitizer we have to fight back against airborne and surface toxins.

This is why one of the confirmed treatments for mould is to lay the affected items out in the sunlight to bake.

Ultraviolet sunlight has a similar effect on coronavirus. The germs simply cannot withstand the sanitizing impact of the sun.

Putting Them Together to Kill Coronavirus: Humidity, Heat & Light

While we don't have a vaccine against the new novel coronavirus yet, we do have some powerful weapons we can use to protect ourselves inside our homes and workplaces.

Here, we will need to take active measures to upgrade our indoor spaces to be less welcoming to coronavirus.

Keeping our homes warmer and more humid may be especially important where a family member is already infected with SARS-CoV-2 and showing symptoms of COVID-19.

Raising the thermostat and adding a portable or whole-home humidifier can help to achieve the higher heat/humidity balance that coronavirus most dislikes.

Installing a portable or whole-home ultraviolet light purifier to work with your HVAC system can then provide an additional layer of protection by purifying your indoor air on a continual basis.
