Have you ever noticed that some mornings you wake up feeling energized, optimistic and ready to embrace the day, while on others, every joint seems a little stiffer, your energy is lower and even small annoyances feel bigger than they should? Most of us simply blame it on getting older. While age certainly plays a role, another powerful influence is quietly at work every moment of every day: your nervous system. So, what exactly is the nervous system? Think of it as your body’s communication network. Your brain, spinal cord and millions of nerves are constantly sending messages back and forth between your brain and every organ, muscle and tissue in your body. This remarkable system controls far more than movement. It influences your breathing, heart rate, digestion, sleep, balance, immune system, energy levels and even how much pain you experience. What has fascinated me as I begin my 48th year in practice is that this communication never stops. Your brain and body are having a conversation every second of every day. The brain’s most important job isn’t to make you happy. Its first priority is to keep you alive. Every moment, it asks one simple question: Longevity Your Brain Is Always Listening Am I safe? Most of us have heard of the ‘fight or flight’ response. I like to think of it a little differently. Your nervous system is constantly shifting between Protection Mode and Restoration Mode. Protection Mode prepares you to respond to danger. Restoration Mode allows your body to heal, digest, repair, recharge and thrive. We need both. If a car suddenly swerves into your lane, you miss a step or unexpectedly roll your ankle, Protection Mode could save your life. The challenge is that your brain doesn’t always distinguish between a real physical threat and one imagined by your thoughts. And, while we often think of stress as something negative, even positive events can push the nervous system into overdrive. Planning a trip, hosting family, volunteering, starting a new project or saying yes to too many wonderful opportunities can all feel exciting ‒ and still become too much. An endless to-do list, rushing from one commitment to the next or constantly feeling overwhelmed sends your brain the message that life is demanding more than you can comfortably manage. Your body may respond as though you’re facing a genuine threat ‒ your heart rate rises, your muscles tighten, your breathing becomes shallower, digestion slows and energy is redirected toward protection rather than restoration. The same is true when you worry about a medical test, imagine the worst for someone you love, replay yesterday’s argument or stress about tomorrow’s finances. Even while you are sitting safely in your favourite chair with a cup of tea, your nervous system may still respond as if danger is just around the corner. That’s because your brain is constantly collecting clues. It listens not only to your thoughts, but also to your emotions, your posture, your muscle tension and, perhaps most important, your breathing. Many of us unintentionally hold our breath while answering emails, watching the news, driving in traffic or worrying about life’s challenges. Others breathe quickly and shallowly without realizing it. To the brain, those breathing patterns can suggest that something isn’t quite right. On the other hand, a slow, relaxed breath ‒ especially one with a long, gentle exhale ‒ sends a very different message. 42 | www.snowbirds.org
