Scroll through social media and you’ll find endless advice about calming your nervous system, getting out of fight-or-flight, and “resetting” your body. It seems to be everywhere, alongside conversations about anxiety, stress, burnout, sleep, and feeling overwhelmed. We’re told we need to “regulate,” “reset,” or “calm” our nervous system, but what does any of that actually mean? And why has our nervous system suddenly become the star of the wellness world?
The truth is, there’s a lot of science behind the conversation, but also a lot of misinformation. So let’s take a step back and look at what your nervous system actually does, why it matters, and how stress fits into the picture. Understanding your nervous system can help you better understand your body’s response to stress, why recovery matters, and how simple practices like movement, mindful breathing, and rest can support your overall well-being.
What Is Your Nervous System?
Think of your nervous system as your body’s communication and control network. Your brain, spinal cord, and nerves are constantly sending and receiving information, helping you respond to what’s happening both inside and outside your body. It helps you move your muscles, feel sensations, remember things, think, breathe, digest your food, regulate your heart rate, and respond when something feels threatening. Some of these things you consciously control. You decide to lift your arm, walk into class, or hold a Pilates position. Other things happen automatically. Your heart beats. Your pupils adjust. Your digestion continues. Your breathing changes depending on what you’re doing. That’s where the autonomic nervous system comes in.
Your Body Has an Accelerator and a Brake
The autonomic nervous system helps manage many of the body’s automatic functions, including heart rate, breathing, blood pressure, digestion, and more. It has two major branches that often get the most attention: the sympathetic nervous system and the parasympathetic nervous system.
You can think of the sympathetic system as your body’s accelerator. It helps you respond when you need energy, focus, or action. This is the system involved in the familiar fight-or-flight response. Your heart rate and breathing can increase, your muscles become more ready for action, and your body temporarily shifts its resources toward dealing with whatever is happening. The parasympathetic system is often described as the brake. It helps support rest, digestion, recovery, and other functions associated with a calmer state.
Both of these systems serve a function, and you need both. Your body isn’t supposed to be calm all the time. You want your nervous system to be able to ramp you up when you need to react, protect yourself, or perform and then be able to settle back down when it’s time to rest, recover, and simply live your life. That’s what healthy regulation really is: flexibility.
So What Happens When Stress Sticks Around?
Your nervous system is designed to respond to stress. That’s a good thing. If you were walking down the street and a car suddenly came toward you, you would want your body to react quickly. The problem is that modern life can give us plenty of reasons to feel “on” and alert without ever giving us a clear moment when the threat is actually over. Work deadlines. Traffic. Notifications. Family responsibilities. Financial worries. Too much screen time. Too little sleep. A never-ending to-do list. Even when you’re physically sitting still, your brain may still be processing stress. Long-term stress can affect sleep, digestion, mood, muscle tension, headaches, and other aspects of health. It can also contribute to or worsen anxiety and other serious health conditions. That doesn’t mean every headache or sleepless night means your nervous system is “dysregulated.” Our bodies are complicated, and symptoms can have many different causes. But if you frequently feel tense, restless, overwhelmed, wired, or like you simply can’t switch “off”, it may be worth paying attention to how much stress you’re carrying and how much time you’re giving your body to recover.
How Can You Support Your Nervous System?
The good news is that supporting your nervous system doesn’t require an elaborate wellness routine or the latest viral “reset.” Many of the things that help your body move from a heightened state back toward rest and recovery are surprisingly simple. The goal isn’t to eliminate stress or keep your nervous system calm all the time, it’s actually to give your body opportunities to shift gears when the stressful moment has passed.
Breathe. Your breathing and nervous system are closely connected, which means changing the way you breathe can send signals to your body that it’s time to slow things down. Slow, controlled breathing can encourage a more relaxed state and help reduce feelings of stress. The next time you feel yourself getting wound up, try slowing your breath: breathe in gently for 4 seconds, hold for 2, breathe out slowly for 6 seconds, and hold for 2. Repeat for a few minutes, keeping your breath comfortable and steady. You don’t need to take huge breaths, just give yourself permission to slow down.
Move. Movement gives your nervous system something to respond to. When you exercise, your body naturally becomes more alert and energized and then, when the workout is over, it gets the opportunity to recover. That cycle of activation and recovery is an important part of a healthy, adaptable nervous system. Practices like Pilates, barre and yoga add another layer because you’re not only moving; you’re concentrating on your breath, your muscles, your balance, and your body’s position in space. You’re giving your brain something to focus on while giving your body a chance to release some of that built-up energy.
Sleep. Your nervous system needs recovery just as much as your muscles do. Sleep gives your body and brain time to restore and recover after everything you’ve asked of them during the day. If you’re constantly running on empty, your body has less opportunity to come back down after periods of stress. Protecting your sleep is not unproductive, it’s crucial for taking care of your nervous system.
Pause. Your nervous system doesn’t necessarily know that the workday is over just because you closed your laptop. If you’re immediately moving from emails to errands to scrolling to the next thing on your list, your brain may never get much of a chance to slow down. Build small pauses into your day. Step outside. Sit quietly for a few minutes. Put your phone down. Take a few slow breaths. These little moments give your body a chance to shift out of constant stimulation.
Connect. Feeling safe and connected to other people matters, too. Spending time with people you trust, laughing with friends, hugging someone you love, or simply being around people who make you feel comfortable can help create a sense of safety and ease. Your nervous system doesn’t exist in isolation, it is constantly responding to the world around you, including the people and environment you’re sharing it with.
And perhaps the biggest takeaway is this: you don’t have to “fix” your nervous system. It’s already working incredibly hard for you every second of every day. What you can do is give it regular opportunities to work hard when you need it, and then slow down, recover, and return to a calmer state when it’s safe to do so.
And This Is Where the Vagus Nerve Comes In…
This remarkable nerve plays an important role in helping your body shift toward rest and recovery after periods of stress. It connects your brain with many of the organs in your chest and abdomen, carrying information back and forth between your brain and your body. You’ll find it mentioned everywhere from podcasts to TikTok videos, often alongside claims about anxiety, digestion, stress, sleep, and “vagus nerve resets.” But what does this nerve actually do? And why has it become such a big deal? That’s what we’re getting into next.
Stay tuned for Part 2 exploring the vagus nerve and the role it plays in helping you return to a calmer state.
