Once you get beyond the initial learning curve, knitting and crocheting can lower heart rate and blood pressure and reduce harmful blood levels of the stress hormone cortisol."
There is some evidence that stitching can reduce feelings of depression, help people cope with chronic pain, and even ward off decline in brain function as we age.
