Yoga is a homeopathic approach to quelling allergies by facilitating the necessary prevention and management of allergy symptoms. Yoga has been shown to have a stabilizing effect on the immune system, and with a regular yoga practice, the overall health and local resistance in respiratory passages are improved; making it easier for your body to fend off allergens. Yoga is also an effective stress management technique (stress can lower your immune system).
Shoulder Stand and other Inversions open nasal passages and improve drainage. However, do not hold for more than a minute or two at a time so as not to create too much pressure.
Plow Pose opens the muscles at the base of the skull and the back of the neck, where pressure tends to accumulate. When these muscles are loose, drainage is clearer.
Bridge Pose and other Backbends open your chest space. Backbends will not only help with allergies but also to undo all the forward moving/leaning postures (sitting in front of a computer, driving, etc.) that make us collapse in the chest. Back-bending is a fantastic way to expand the chest and lungs and increase lung capacity.
Three-Part Yogic Breath helps increase lung capacity. It also helps to reduce stress, which will improve immunity and make you less susceptible to allergies and colds.
Fish Pose is another great way to open the chest, lungs, and throat to free the breath. This pose stimulates the thymus gland, which is located under the sternum.
