With the warmth of spring comes the suffering of hay fever or seasonal allergies (花粉症). On the train and at work we hear people sniffling and sighing, tired from allergy medicine and too much sneezing. The sad part is, allergy medicine makes use weaker, so that we need stronger allergy medicine as we get older. Fortunately, we CAN strengthen our immunity (免疫力) and relieve the symptoms of allergy with yoga. Of course, yoga is what we call “slow medicine”, it takes time and practice to work. But I assure you, the more you practice the better you will feel. Yoga may also be used WITH medicine to make it more effective.

Yoga practice can relieve your allergies in two major ways. First, yoga helps to strengthen the immune system by calming the nervous system (神経系). Allergies tend to make people feel irritated, what with a constantly running nose and itchy eyes. Practicing yoga forces you to slow down your breathing, which makes you calm. Inversions (逆さまのポーズ) stimulate lymph flow, which helps your body get rid of allergens (things that give you an allergic reaction). Second, breathing exercises, like Kapalabhati, help decongest the nose so you can breathe more easily. Chest opening exercises, like Fish pose, are also helpful.
