Is it Healthy to Exercise in Wildfire Smoke?

Living in this area, we already have a strong tendency to overdo exercise. As health care practitioners, we see overuse injuries all the time. And you know you don’t always give your body time to rest and recover after a big event or to heal after an injury. How likely are we to temper our exercise enthusiasm during wildfire smoke, and how necessary is it really?

Is exercising outdoors when it is smoky doing us more harm than good?

Good question. And a bit of a complicated one.

What is in wildfire smoke that is dangerous?

First, lets talk about the type of particles released from wildfires. Most specifically the particle called PM2.5 — fine particulate matter smaller than 2.5 micrometers in diameter.
The scary thing about PM2.5 particles is that they are easily breathed in, and once they hit our lungs they cause irritation and inflammation with sometimes serious repercussions.

For most of us, we have mild symptoms such as:
• Itchy or watery eyes
• Sore throat
• Runny nose
• Mild cough
• Phlegm & mucus production
• Wheezing
• Headache

More serious symptoms can result such as:
• Shortness of breath
• Severe cough
• Dizziness
• Chest pain
• Heart palpitations

If you are experiencing these, get out of the smoke and please get medical attention if symptoms persists.

Children, the elderly and those with lung conditions are more affected by air quality and should be more careful to avoid exposure.

How to Check Air Quality

Look at both the Air Quality Index (AQI) and specifically the PM2.5 measurement for your area. I use AirNow

Well, the Air Quality Index is not looking great, but I want to exercise. Consider these options:

Exercise indoors in a place with a good air filtration system, specifically with a HEPA filter.

Monitor the Air Quality and choose your time of day for exercise based on that.

Anecdotally, I notice less smoke here in the morning and like to get out then.

Do lower intensity exercise.

While doing strenuous exercise you breathe 10 times more air than while resting, thus increasing your exposure to these particles by 10 times. Less gasping for air equals less exposure. Source

Change your elevation.

Sometimes you can get above the smoke. Try a hike at the top of Teton Pass, off the Tram or your own high elevation favorite.  Keep in mind, it’s not always comforting to look down at the smoke below you.

Drink water and eat a diet that will help you combat the inflammation caused by the smoke.

Consider a respirator/ N95 mask.

If you work outside or for low intensity exercise, wear a respirator/ N95 mask. A well-fitted N95 can reduce PM2.5 exposure by 95% Personally, I can’t handle wearing one while running or biking, but despite the annoyance I can walk with one on. You can find them at the hardware store.

More harm than good exercising outside in wildfire smoke? Not necessarily.

Although this study was done in an urban area, measuring urban pollutants, the PM2.5 levels were considered, low intensity exercise, eg. commuting by bike or walking, seems to convey health benefits that outweigh the harm for healthy adults when the PM2.5 levels are under 95 μg/m3 and for lower concentrations, less than or equal to 22 μg/m3 the outlook is better.

“PM2.5 concentration (22 μg/m3) benefits of physical activity by far outweigh risks from air pollution even under the most extreme levels of active travel. In areas with PM2.5 concentrations of 100 μg/m3, harms would exceed benefits after 1 h 30 min of cycling per day or more than 10 h of walking per day.  For half an hour of cycling every day, the background PM2.5 concentration would need to be 95 μg/m3 to reach the tipping point.” Read the study

Bear in mind this study was done in urban areas with more pollution than wildfire smoke causing the increased PM2.5 and that they were commuting by bike, not charging up Ferrin’s or Putt-Putt.

The truth is we need more data to determine the risks vs benefits.

What is Fascia?

Addressing the Fascia in Myofascial Release

Fascia – what exactly is it? Fascia is a fibrous web-like tissue that covers our muscles, nerves and organs. Remember the last time you ate an orange? The peel is synonymous with our skin. Our muscles, nerves and organs equate to the actual fruit. The white material that separates the different orange slices, that is our fascia.

Quite a bit of research has gone into this area as of late, and we are beginning to understand just how important this anatomical structure is to our physiological function. Fascia, it turns out, is highly responsible for maintaining the structure of our muscles, joints, tendons and bones. Just like these other tissues, fascia can also be injured. It can stretch, fold, wrinkle, and even tear. When this happens, fascia tends to heal as scar tissue. This scar tissue is less pliable than normal fascial tissues as it contains a criss-crossing of fibrous tissues. Myofascial release, specifically the Active Release Techniques that we perform at JH Backcountry Health, helps to realign those fibers returning the fascia tissue to its normal function.

What kind of issues can fascial adhesions cause?

  • Headaches
  • Joint pain
  • Plantar fasciitis and other foot pains
  • Nerve entrapments such as carpal tunnel
  • Limited mobility
  • Diminished athletic performance

So hop on our schedule to get these issues resolved!

Best of Jackson Hole 2019 Alternative Medicine Practitioner

We thank you for your support! It is such an honor to make it on the Best of Jackson Hole list. Dr. Mark Menolascino and Kevin Meehan are some big names to follow! It is so exciting for us as we are just over a year into practice here.

So what does it mean to be an Alternative Medicine Practitioner?

For us, it means we do our best to help you heal so you can get out and do what you love. Chiropractic means “done by hand.” We use our hands to diagnose and to treat. We love working on shoulders, hips, knees, feet, gait patterns, and core conditioning as well as the normal chiropractic targets of back pain and headaches. Our goal to is find the cause of your pain and dysfunction and address it. We treat using muscle release techniques, adjustments, and therapies, then teach you exercises and stretches to you can maintain (and not have to visit us too often).

We also value the role of tradition medicine. If you need care that isn’t in our scope, we will recommend another medical professional. There are some great ones in this town.

And so you know, it is our favorite thing when we run into you on the slopes, out hiking, or dancing at Bluegrass Tuesday. It is always encouraging to see you living your life so fully. Keep enjoying!

Much love,
Dr. Laura and Dr. Tyler
