1. Anything that involves moving your body

Any kind of activity where you have to be immersed into it both mind and body helps you reset yourself from work related thoughts.

Examples: cycling, skating, basketball, kite-surfing, surfing, yoga, etc.

2. Any kind of activity where you have to concentrate and use your hands.

For example, all kinds of crafts, gardening, home repairs, etc.

3. Arts and music.

Though it's important to remember that you don't have to strive for perfection, it should be something that you love doing instead of something that you have to push yourself to do.
