Listening to music can have a tremendously relaxing effect on our minds and bodies, especially slow, quiet classical music. This type of music can have a beneficial effect on our physiological functions, slowing the pulse and heart rate, lowering blood pressure, and decreasing the levels of stress hormones. As music has a tendency to absorb our attention, it can act as a distraction, and sometimes a little distraction is all we need for some new vigor and fresh perspective.
Most of the time when people are very stressed, there is a tendency to avoid actively listening to music. Perhaps it feels like a waste of time, not helping to achieve anything. But as we know, productivity increases when stress is reduced, so this is another area where you can gain vast rewards. It just takes a small effort, to begin with, but in time, it can be a used as a daily tool to stay focused and get more done.
