Things to remember about the mind-body loop: The way you treat your body has a direct, immediate impact on your brain’s performance, affecting both its cognitive and emotional functions. Specifically, your brain’s deliberate system performs far better when you’ve had enough sleep, some aerobic exercise, and a few moments of mindfulness. Mimicking the physical actions associated with feeling happy, confident, and relaxed appears to tell your brain that you are in fact happy, confident, and relaxed, creating a self-fulfilling loop.
