If I knew how much breathing impacted your stress, clear-headedness and overall health, I probably would have done a lot better in college.
To my embarrassment, I only found out a year ago that it's unhealthy to breathe through your mouth. (I guess I missed that lesson in school.)
But most of us still manage to over-breathe. You can read all about it in The Oxygen Advantage.
Better yet, when we perform in public, we often forget to breathe altogether.
But when you work on your breathing, a lot of other things become easier. And, there are simple breathing things you can do that dramatically alter your state of mind and being.
Don't believe me? Try this exercise, and let me know what you think.
