One tool that can be helpful for calming yourself (activating your parasympathetic nervous system -your vagus nerve) and reaching this fully resourced state is to take a big breath in through your nose and then just when your lungs are full take a little extra sip in, then let it all out through your mouth. Repeat this three times or for three minutes as you choose.

This takes less than 30 seconds; it is useful as you start to feel elevated/ stressed or ahead of time if you are about to enter a difficult situation.
