Our body is built to survive, but sometimes its own mechanisms get in the way of what it is trying to accomplish. 

In other words, your own survival response, the flight or fight response, can be overactivated to things that don’t necessarily require a true flight or fight response. 

In order to overcome an overactive flight or fight response, we might need to switch out of an overactive sympathetic state and instead, find a way to get into a parasympathetic state. 

This is where controlled breathing can play a role in your ability to shift out of a sympathetic state and back into a parasympathetic state, especially when overactivity of the sympathetic states is present. 

So long story short, we can use breathing to help us regulate our own states and help us get out of unnecessary fight or flight states.
