I also wonder if it would have to be yoga or if it could be any increase in physical activity?
I am not really into yoga, per se, but I would do secular stretching exercises.
Ti Chi practice is pretty helpful- and soem other forms of martial arts that are more geared towards he stretches and movements and balance than actual combat-
The article says “Kundalini yoga is a method that focuses on meditation and breathwork more so than physical poses.” So this appears to be more mindfulness rather than physical. You probably need both.
