This is something that we've done our entire life and still we haven't mastered it, this is due to countless variables, but one of those we could say that is the fast life we have in big cities.

If you take a look in the video below, you'll see a few breathing patterns along with specific situations for each one of those. Those are some of the names gathered in medicine along the years to describe breathing patterns that we have as humans, but they're not exactly ready for usage as they do not relate specifically to a current emotion, and more likely to how our body is chemically/hormone related responding.
