Music is a complete mental workout. Music has been shown to reduce anxiety, blood pressure, and pain, as well as improve sleep, mood, mental alertness, and memory. Music has the ability to lift someone’s spirits, enthuse them, or calm and relax them. Music also allows us to feel almost, if not all, of the emotions we encounter in our everyday lives. Music provides us with confidence and strength whenever we need it. When we are anxious, it can calm us down; when we are tired, it can motivate us; and when we are pushed down, it can re-inspire us.
