It helps to slow down the mind, allow it to rest and to let go of work at the end of the day so you don't take it home with you. This leaves you free to enjoy your evening fully and to sleep well.
It's sophistocated physical aspects of developing one's body awareness, good structural alignments and an emphasis on applying full effort without strain creates the ideal conditions for resolving many long term physical issues such as knee, back and neck pain.
