Deliberate hyperventilation technique linked to mental break before police standoff
CHILLIWACK — A British Columbia judge has sentenced a man to about 75 days in jail with time served, saying that despite his attempts to murder police officers in a standoff, a single mental health break likely triggered by holotropic breathwork led to the offence.
A doctor said in a psychological assessment for the court that he couldn’t conclude the exact cause of Daniel Hackl’s mental break, but found “it was most likely triggered by ‘holotropic breathwork,’ a practice that Mr. Hackl had taken up around the time of his decompensation and which he practised more than once a day,” said the ruling released online June 24.
A 2015 study out of Denmark says the breathwork is a psychotherapeutic practice involving hyperventilation, or deep overbreathing.
The study found it can “induce very beneficial temperament changes, which can have positive effects on development of character, measured as an increase in self-awareness.”
