Shaula EvansA few years back I read a fascinating study about different types of intentional breathing for lowering stress and emotional regulation. One of the styles the studied was 'box breathing", which they expected to be most effective. They were surprised that the winner was breathing in on a 4 count and breathing out on a 6 count.
