A prison in Norway has stopped holding yoga classes after it found that instead of calming inmates, they were actually making some more aggressive.
High-security Ringerike jail near Oslo offered the classes to eight inmates on a trial basis earlier this year.
Prison warden Sigbjoern Hagen said some of the inmates became more irritable and agitated and had trouble sleeping.
He said the prison did not have the resources to treat emotions unleashed by the deep breathing exercises.
The yoga group expressed surprise at the prison's findings.
Has Sheriff Joe considered yoga for his clients I wonder?
