Sure you’re asana practice provides several means of supporting your immune system, both by lowering stress hormones that compromise it and by stimulating the lymphatic system. If you are practicing yoga regularly, maybe bring a Tortoise pose, Camel and Cow, if the bug relates to bronchial congestion.
But I promised you 3 easy, travel-ready, and waiting in line or traffic ways so…
1. Dog Breathe
With your chin in and your chest out, stick your tongue all the way out and keep it out as you rapidly breathe in and out through your mouth. Panting this breath for a few minutes. Keep it silly for the effects of an energized immune system. Finish by inhaling and hold your breath for 15 seconds and press your tongue against the upper palate. Exhale. Repreat this sequence two more times.
2. Node Pump
Slide fingers just beneath jaw to locate tiny, pearl-shaped lymph nodes. With fingers right against the bone, pump the nodes with gentle yet firm pressure. Repeat up to every few hours.
3. Hands Up
Touch palm with your middle finger, pressing in just above the mound of muscle that is below the thumb and make gentle, slow, circles for respiratory system stimulation.
