Whether you're navigating the morning chaos of back-to-school drop-offs, stepping into a new job, starting college, or adjusting to life with a newborn, your nervous system is already working overtime. You’re out of your comfort zone, and your body knows it: stress is taking over.
So if you’re feeling more irritable, overwhelmed, or drained than usual, it’s not just in your head. It’s in your nervous system.
Let’s break down what’s really happening, and how to reset your body back to calm.
Why Change Equals Stress (even the good kind)
Change, even the exciting kind, triggers stress. That’s because your body is wired to perceive any uncertainty or increased demand as a potential threat. From an evolutionary standpoint, your brain’s #1 job is to keep you safe. So when your environment shifts or your routine is disrupted, your brain flips the switch to "fight-or-flight" mode.
This stress response is controlled by your sympathetic nervous system, and it's incredibly useful in emergencies. It floods your body with stress hormones like cortisol and adrenaline, increases your heart rate, and sharpens your focus.
But here's the problem:
Today’s stressors aren’t wild animals or life-or-death threats, they are:
- 🚗 Morning routines that feel like a triathlon
- 📲 Work emails before your coffee’s even brewed
- 🧠 Mental load from juggling kids, deadlines, or new responsibilities
- 💭 Pressure to perform, show up, and do it all perfectly
And your body responds the same way as it would to a real threat, every single time.
Chronic Fight-or-Flight: What It’s Doing to Your Body
If you stay in sympathetic overdrive for too long, your body can’t recover. This is when stress becomes chronic, and you might notice:
- Fatigue (even after sleeping)
- Headaches or muscle tension
- Mood swings or anxiety
- Digestive issues
- Hormonal imbalance
- Trouble concentrating
All of these are signs that your body is stuck in survival mode.
The Missing Link: Your Parasympathetic Nervous System
To reset, your body needs to activate the parasympathetic nervous system, often called the “rest and digest” mode. This is your calm state. It slows your heart rate, reduces inflammation, improves digestion, and allows your body to heal.
But here’s the catch: it doesn’t just turn on by itself. You have to train your body to access it.
And yes, you can train it, just like a muscle.
The Science of Getting Back to Calm
When your nervous system gets stuck in fight-or-flight mode, it needs intentional cues to shift gears into parasympathetic regulation, your body’s rest, digest, and repair state. Here’s how science says you can make the switch.
1. Breathwork: Directly Talking to Your Nervous System
Your breath is the fastest way to influence your autonomic nervous system, and it works in both directions. Slow, intentional breathing stimulates the vagus nerve, a cranial nerve that acts as the main communication highway between your brain and body.
When the vagus nerve is activated, it sends a “stand down” signal to your stress-response centers, lowering heart rate, blood pressure, and cortisol levels.
Research has shown that paced breathing at 5–7 breaths per minute (slower than our typical 12–20 breaths per minute) significantly improves heart rate variability (HRV),a key marker of nervous system flexibility and resilience. High HRV is associated with better recovery, emotional regulation, and even reduced risk of cardiovascular disease.
💡 Pro Tip: Try “6 breaths per minute”: inhale for 4 seconds, exhale for 6 seconds, for a minute.
2. Cold Therapy: A Shortcut to Calm
Cold exposure, whether it’s a splash of cold water on your face, a brief cold shower, or stepping into chilly air, activates the mammalian dive reflex, a physiological response designed to slow your heart rate and conserve oxygen.
This reflex is also mediated through the vagus nerve, meaning cold exposure directly triggers parasympathetic activation.
Studies show short-term cold exposure can:
- Reduce sympathetic nervous system dominance
- Improve mood through increased norepinephrine release
- Increase resilience to future stressors
💡 Pro Tip: You don’t need an ice bath: start with 30 seconds of cold water at the end of your shower.
3. Grounding: Reconnecting with the Earth’s Electrical Field
Grounding (or “earthing”) means making direct skin contact with natural surfaces like grass, sand, or soil. While it sounds simple, there’s intriguing evidence that it can reduce anxiety and inflammation.
The Earth carries a mild negative charge. When you connect directly, your body can absorb free electrons that may neutralize excess free radicals, reducing oxidative stress, a process linked to chronic inflammation.
In addition, grounding often means slowing down, being outdoors, and engaging your senses, all of which signal to your nervous system that you’re safe.
Studies have found grounding can:
- Lower cortisol levels
- Reduce perceived stress
- Improve sleep quality (by influencing circadian rhythm)
💡 Pro Tip: Spend 10–15 minutes barefoot outdoors daily, ideally in the morning sunlight for an added circadian boost.
4. Small Acts of Regulation: Micro-Resets Throughout the Day
Your nervous system doesn’t just benefit from big, dedicated sessions of meditation or breathwork, it thrives on frequent micro-adjustments. These short, intentional breaks help prevent stress accumulation and keep you from tipping into chronic sympathetic overdrive.
This concept is supported by allostatic load theory, which explains that the total “wear and tear” on your body from repeated tensions determines long-term health outcomes. Micro-resets reduce this load.
Examples:
- Pause before diving into work → Signals to your brain you’re in control of your pace
- Short walk after the morning rush → Physical movement helps metabolize stress hormones
- Breath reset before reacting → Keeps you from reinforcing a stress-triggering loop
💡 Pro Tip: Set reminders to pause for 60–90 seconds every 1–2 hours, stand, breathe, or stretch to break the anxiety cycle.
You're Not Meant to "Power Through"
Getting out of your comfort zone is part of growth, whether you're taking on new roles, building a family, or chasing big goals. But your nervous system needs support to adapt, not pressure to keep going.
So this season, don’t just go back to school or back to work: Go back to calm.
Support your nervous system. Reset your stress response. And train your body to thrive through every change

FAQs
What is the fight-or-flight mode?
The fight-or-flight mode is your body’s natural stress response. When your brain senses a threat, your nervous system releases stress hormones like adrenaline and cortisol. These increase your heart rate, breathing, and alertness, preparing you to either face the challenge (“fight”) or escape it (“flight”). While helpful in emergencies, everyday stress can keep you stuck in this state, leaving your nervous system overwhelmed.
What is the parasympathetic system?
The parasympathetic system is the “rest and digest” part of your nervous system. It helps your body recover after stress by slowing your heart rate, aiding digestion, and restoring balance. When active, it promotes calm, relaxation, and healing.
What is the vagus nerve?
The vagus nerve is a crucial component of the parasympathetic nervous system (PNS), extending from the brainstem down through the neck, chest, and abdomen. It plays a key role in regulating a wide range of bodily functions, including heart rate, digestion, and respiratory rate. As the longest cranial nerve, it influences many organs and systems, promoting a state of calm and relaxation.
What is HRV?
HRV, or Heart Rate Variability, is the natural variation in time between each heartbeat. It reflects how well your nervous system adapts to stress and recovery. A higher HRV generally means your body is more resilient and balanced, while a lower HRV can signal stress, fatigue, or strain on the body.
