Denver Haze: How Wildfire Smoke Ruins Lung-Cleansing Yoga

By Franklin Everett Shaw

The acrid smell stings your nostrils, even indoors. Denver’s majestic mountain views are obscured by a hazy, orange film. Wildfire season is no longer a distant threat; it’s a harsh reality impacting our daily lives, especially for those of us who cherish the revitalizing practice of yoga. But fear not, fellow Denver yogis! We can adapt and continue to nurture our lungs and minds, even when the air outside is far from breathable.

Forget the Instagram-worthy poses on Red Rocks for now. Our focus shifts to creating a sanctuary within our homes, a space where we can safely practice and protect our respiratory systems.

First, let’s talk air purifiers. Not all purifiers are created equal. You need a HEPA filter, specifically designed to capture the fine particulate matter (PM2.5) that’s so prevalent during wildfires. Look for models with a high CADR (Clean Air Delivery Rate) rating, indicating how quickly they can clean a room. Don’t skimp on this; your lungs will thank you.

Consider the size of your yoga space. A small studio apartment in Capitol Hill will require a different purifier than a sprawling Victorian in City Park. Measure your square footage and choose accordingly.

Now, let’s address the elephant in the room: breathing exercises. The powerful kapalabhati (skull shining breath) and bhastrika (bellows breath), often staples in lung-cleansing routines, are not your friends right now. These forceful techniques can irritate already inflamed airways.

Instead, embrace gentler practices. Ujjayi breath (victorious breath), performed with a slight constriction in the back of the throat, can help calm the nervous system and improve oxygenation without excessive exertion. Think of it as a gentle massage for your lungs.

Another excellent option is nadi shodhana (alternate nostril breathing). This balancing practice helps to clear the nasal passages and promote a sense of calm. It’s particularly beneficial for those experiencing anxiety related to the wildfire situation.

Here’s a simple step-by-step guide to nadi shodhana:

1. Sit comfortably with a straight spine.
2. Close your right nostril with your right thumb.
3. Inhale deeply through your left nostril.
4. Close your left nostril with your right ring finger and release your right thumb.
5. Exhale slowly through your right nostril.
6. Inhale through your right nostril.
7. Close your right nostril with your right thumb and release your left ring finger.
8. Exhale slowly through your left nostril.
9. Repeat steps 2-8 for 5-10 minutes.

Remember to listen to your body. If you feel any discomfort or shortness of breath, stop immediately.

Monitoring air quality is crucial. Relying solely on your senses is not enough. Download the EPA’s AirNow app or check the Colorado Department of Public Health & Environment’s website for real-time air quality data specific to your neighborhood. Pay attention to the Air Quality Index (AQI) and follow the recommended guidelines.

Many yoga studios in Denver are adapting to the wildfire season. Call ahead to inquire about their air filtration systems and whether they’re modifying their classes to accommodate those with respiratory sensitivities. Some studios in areas like Cherry Creek or Wash Park may have invested in advanced air purification systems, making them safer havens for practice.

Consider online yoga classes. Many local instructors are offering virtual sessions, allowing you to practice safely from the comfort of your home. This is a great way to support your favorite studios and maintain your practice without risking exposure to poor air quality.

What about when the air does clear? Don’t rush back to your outdoor yoga mat just yet. Denver’s altitude already puts extra stress on the respiratory system. Add in lingering smoke particles and seasonal allergens, and you’ve got a recipe for trouble.

Wait for several days of consistently good air quality before resuming outdoor practices. Even then, take precautions. Avoid practicing during peak pollen hours (typically early morning and late afternoon). Choose locations away from busy roads and construction sites.

And remember, Denver is notorious for its sudden weather changes. A seemingly clear morning can quickly turn smoky if the wind shifts. Always check the air quality forecast before heading out.

One common mistake is assuming that a face mask provides adequate protection during yoga. While a surgical mask or cloth mask may offer some minimal filtration, they are not designed to filter out the fine particulate matter found in wildfire smoke. For effective protection, you need an N95 or P100 respirator mask, properly fitted.

However, exercising with a respirator mask can be challenging, especially at Denver’s altitude. It can restrict airflow and make breathing more difficult. If you choose to wear a mask, start slowly and gradually increase the intensity of your practice.

Another pitfall is neglecting hydration. Wildfire smoke can dehydrate you, making it harder for your body to clear toxins. Drink plenty of water throughout the day, especially before, during, and after your yoga practice.

Finally, be patient with yourself. Wildfire season is stressful, and it’s okay to modify your practice or take breaks when needed. Prioritize your health and well-being above all else.

By adapting our practices, utilizing available resources, and prioritizing our respiratory health, we can navigate Denver’s wildfire season with resilience and continue to reap the benefits of yoga, even when the air outside is less than ideal. Stay safe, breathe deeply (and consciously), and remember that this too shall pass.
