When you practice yoga in balance – in alignment, with awareness and mindfulness of breath – it all contributes to balancing hormones. Rather than breaking it down to specific poses in your mind (which could give the more limited idea that only those poses help), know that the whole practice of yoga creates more harmony.
Part of what makes yoga so healing is bringing more circulation to the body, which nourishes every system including the glands which produce hormones. Also, yoga can be enormously beneficial in lowering your stress levels. This alone supports harmonious hormones, as many of our hormones are designed to react to stress.
Knowing this, there are certain poses and groups of poses that can help you find balance.
