CHILLIWACK - A British Columbia man who began to deliberately hyperventilate himself daily before suffering a mental breakdown was sentenced to four years in prison last month after shooting at police in a 2022 standoff.

A psychological assessment found Daniel Hackl's breakdown was likely triggered by "holotropic breathwork," a therapeutic practice involving heavy, rapid breathing exercises that can exacerbate certain mental health conditions.
