“Meditation is one of the ways to engage in restorative activities that may provide relief for our immune systems, easing the day-to-day stress of a body constantly trying to protect itself.
You have two complementary and intertwined nervous systems: your parasympathetic nervous system, and your sympathetic nervous system.
Your parasympathetic nervous system is also known as your “rest and digest” system, because that’s what you’re doing when it’s activated. Your whole body is focused on resting, digesting, and repairing itself. Ideally, you would spend most of your daily life in this mode.
Your sympathetic nervous system, on the other hand, is responsible for getting you out of trouble. As soon as you detect a threat in your environment (or imagine one), your “fight, flight or freeze” reaction kicks in.
Your heart races, your palms sweat, it’s harder to think about anything more complex than the next move you’re about to make until you make it and return to safety. Ideally, you would have incidents where you needed this reaction, and the rest of the time you’d be in that “rest and digest” mode.
