There have been several recent studies, like this one, that have definitively proven that multi-tasking is not only inefficient, but also harmful to the brain. Frequent or chronic multi-taskers use their brains less effectively than folks who focus on one task at a time.
This, of course, is not news to ancient Yogis who knew the value of singular focus and a less cluttered brain. The Yoga Sutras of Patanjali talk about training the mind to focus on one single principle or object.
Despite the research, multi-tasking still seems to be a badge of honor and something that is highly valued in a prospective employee. It may take a few years for the research to catch on, but in the meantime we can all benefit from unlearning this “skill”. Not just in our work life, but in our personal lives as well. So much of each moment is missed when our brains are occupied with things that have happened, are happening simultaneously, or will be happening.
Like any habit we’ve formed, in order to change it, we need to form a new habit by repetitively and mindfully choosing to focus on one thing at a time. A regular and comprehensive yoga (meaning, ALL of yoga, not just asana) practice is a good way to train the mind for singular and directed focus. By giving our brains the opportunity and space to focus on our breath and only our breath we begin the hard work of retraining ourselves to operate more effectively and efficiently in a world that is built around multi-tasking.
One breath at a time, one moment at a time, one thing at a time.
