For people who are shy about speaking up, Simhasana pranayama is a great way to let out some noise. When you roar in Simhasana, your air should flow out freely. Do your best not to constrict the throat - this is all about freeing it up! The breath instead comes from contracting the abdominal muscles and the pelvic floor.
Diaphragmatic breathing is something we do instinctually. It’s also something we can easily do consciously. Just like other forms of mindfulness, diaphragmatic breathing can have far-reaching benefits, not the least of which is that breathing is good. And when you’re breathing with your diaphragm into the furthest reaches of your lungs, it can be even better.
Surprising as it may sound, buzzing like a bee can be just about the most relaxing, mind-numbing way to settle your head. When you breathe in the Humming Bee Breath manner, you'll quite literally set your brain abuzz.
This is a combination of breathing and thinking. Not a lot of thinking, mind you! Just a bit to help your breath focus in a particular way. In exchange, this exercise doesn’t require you to maintain a set rhythm or muscular use. The focus here is not exactly how you breathe, but why.
