A quick check of Timothy’s list of 75 health conditions that yoga helps does have one reference to a study looking at yoga for sinusitis inflammation of the sinus cavities that can be caused by bacteria or virus, as well as allergens, Efficacy of daily hypertonic saline nasal irrigation among patients with sinusitis: a randomized controlled trial. Interestingly enough, the study is not looking at what most of us would think of as modern yoga practice via postures, but a practice of using the neti pot to irrigate the sinuses with warm water, a practice that falls into the category of shat-karma or “six acts” of Hatha Yoga, and is actually a preparatory practice called jala-neti, in which water with a bit of salt dissolved in it is sniffed up the nose.
First let me say that I was pleased to see that the study was published in the Journal of Family Practice, one I have subscribed to over the years—way to go, family docs! But what did this study find? They had the experimental group irrigate their sinuses daily for six months, and here is what they discovered:
“Daily hypertonic saline nasal irrigation improves sinus-related quality of life, decreases symptoms, and decreases medication use in patients with frequent sinusitis. Primary care physicians can feel comfortable recommending this therapy.”
Sweet! A little further digging on PubMed brought up this study done in India in 1991 that looked at posture’s effect on nostril dominance, that is, which nostril is more open at any moment. If you check yourself throughout the day to see which nostril is more open, you will note that it changes every few hours. The author noted that if you started out lying on your back and your left nostril was more open and the right one more congested, by lying on your left side, within in a four to eleven minutes, the right side will become more open and the left side will become more congested. The author postulated that this was “a reflex effect due to the pressure stimuli to the lower lateral side of the body particularly around the shoulder region and effect was mediated through the sympathetic innervation to mucosal venous sinuses of the nostrils.”
This could play out in our yoga asana practice in side lying poses like Vishnu’s Couch (Anantasana) or even side bending poses like Triangle (Trikonasana) or Gate (Parighasana). But you’d have to be in them for at least four minutes to start to see the effect! This lead me to another study done in India with that crutch I mentioned at the beginning of the post, and lo and behold, it took about 17 minutes to get the same effect that lying on your side did. Which would you rather try?
If we get back to the idea of yoga asana and related tools for sinuses and, in particular, sinusitis, which can be an actual infection of the sinuses, there are lots of recommendations online. However, inversions are mentioned in several of these, and my experience is that students with sinus congestion from the common cold or sinus infections often have a significant increase in pressure and headache symptoms as well as worsening of breathing in the forward bend or inversion, often forcing them out of these positions. So for acute sinus symptoms, you may want to hold off on these groups of poses.
According to long-time Iyengar teacher Dean Lerner in an Ask the Expert post for Yoga Journal, inversions again play high on the list of recommended poses, especially Shoulderstand and Plow pose. In addition to the possible worsening effect on acute sinus symptoms, you really need to be a fairly experienced practitioner to do these poses safely. He does postulate that the inverted poses increase the blood flow to the sinuses and this has a flushing effect. However, the blood stays in the blood vessels and does not actually move out into the sinus cavities themselves, so this theory is seriously flawed. And remember, this is just theory, and has not been formally studied.
On the other hand, I found more reasonable recommendations on the Indian Mirror website. The sequence is worth trying because it is unlikely to aggravate sinus pressure and pain while still moving your spine and head into potentially beneficial positions of gentle forward bends, backbends from a prone position, side bends and mild inversions. The sequence features Mountain pose (Tadasana), Seated Forward Bend (Paschimottanasana), Camel pose (Ustrasana), Triangle pose (Trikonasana), Downward-Facing Dog pose (Adho Mukha Svanasana), and Cobra pose (Bhujangasana), and, in an additional section, Knees to Chest pose (Pavanmuktasana, which I usually call Apanasana), Raised Stretched-Out Foot pose (Urdhva Prasarita Padasana), Lion pose (Simhasana), Bow pose (Dhanurasana) and Savasana. And, for breath work, the Bellows Breath known as a Bastrika. If I were to modify this sequence, I’d recommend the following:
- Bending the knees in Paschimottanasana to make it easy on the back
- Skip Camel due to its more advanced requirements
- Monitor Downward-Facing Dog to make sure it does not worsen my symptoms
- Repeat Cobra if Bow pose feels to much for the back
- Elevate the spine and head for easier breathing in the supine position, Savasana
