Let's look at three techniques that are really helpful for vagal nerve activation. Final technique is to double the length of your exhale. When we breathe slowly, specifically, when we emphasize the exhale portion of the breath, that means our diaphragm spends more time relaxed. More time snuggled up against our heart, those baro receptors via our vagus nerve communicate to our brain to slow everything down. These three techniques, ocean breath, chin lock, doubling the length of our exhale is a really, really powerful technique when combined can have a very, very quick self-suiting effect to relieve stress and anxiety.
