Chapters

Humming increases at 15 fold, so you get substantial increase in your own natural defense mechanisms and the ability to lower your blood pressure. And it's hard to be mad when you're humming. So I feel like it just naturally changes your mood. And anything that we do that increases the length of our exhale. So humming increases the length of how long you're breathing out for is going to shift us into a more parasympathetic state. So it's a great way to kind of shift our state, you know, enhance our immune defense mechanisms and also to just kind of feel good.
