Ever feel wired but tired, like you just can’t relax no matter what? That’s your nervous system stuck in fight-or-flight mode. Rather than shutting down after a stressful moment, your body just keeps pumping out the stress hormones such as cortisol, leaving you anxious and tense, and drained.
Normally, your parasympathetic system should kick in to calm things down, but chronic stress can break that balance, leading to burnout, sleep issues, and even physical symptoms such as headaches or gut trouble.
The good news is that you don’t have to change your life completely. Simple daily habits can reset your system and bring you back to a calmer baseline. We’ll dive into those next.
The Vagus Nerve Might Be Your Body’s Best-Kept Stress Secret
Say hello to your new built-in chill switch: the vagus nerve. In fact, it is a pair of nerves running from your brainstem all the way down to your abdomen, and it plays a huge role in your parasympathetic nervous system, aka rest-and-digest mode. When the vagus nerve is activated, it sends a calming signal throughout your body, lowering the heart rate, blood pressure, and basically telling your system, “We’re safe now.”
Various research has found that many of these activities we do to calm ourselves, such as deep breathing, meditation, massage, or simply being lost in a state of awe, work because they all affect the vagus nerve. According to Dr. Jennifer Franklin at Cedars-Sinai, these calming experiences have effects on the brain partly through vagus nerve activation. Translation? When you do things that feel good and grounding, your vagus nerve is often behind the magic.

So, how do you tap into this superpower and quickly calm your nervous system? Let’s talk hacks:
1. Breathe Like You Mean It
Your breath is one of the quickest ways to speak directly with your nervous system. When you slow it down-especially when your exhalation becomes longer than your inhalation-you directly stimulate the vagus nerve and nudge your body into a calm state. Basic breathing exercises like 4-7-8-inhale for 4, hold for 7, exhale for 8-or box breathing-4 in, 4 hold, 4 out, 4 hold-have been scientifically proven to reduce stress by flipping you into parasympathetic mode. Even just 10 deep, belly breaths will signal to your body that it’s safe to relax. And here’s the best part-you can do it anywhere: at your desk, in bed, or even in traffic (maybe skip the breath-holding part while driving!).

2. Chill Out – Literally
Cold exposure might sound crazy, but it’s actually a pretty effective way to fire up the old vagus nerve. If you’ve seen those TikToks about vagus nerve icing, know that there’s real science behind it. Splashing cold water on your face, slapping a cold pack on your neck, or even just taking a 30-second cold shower can trigger the “dive reflex,” which slows your heart rate and sends a soothing signal to your nervous system. Some people swear by dunking their face in a bowl of ice water when they feel a panic attack coming on. No need for a full ice bath-just a quick blast of cold will do. And yes, your grandma was right with her “splash cold water on your face” advice.

3. Hum, Sing, Gargle – Engage Your Throat
Your vagus nerve courses through your throat, so anything that exercises those muscles can have a pacifying effect. That is why humming, chanting “Om,” singing loudly in the shower, or even gargling with water can help fire up the nerve and relax you. Ever noticed how yoga chanting leaves you mellow or how singing in the car lifts your mood? That’s vagal stimulation at work. You can also massage your neck or do some easy neck rolls to boost the effect-just be gentle.
4. Awe and Laughter: The Feel-Good Fast Tracks
Believe it or not, getting that goosebump-producing feeling of awe-like watching a sunset, staring at the stars, or listening to beautiful music-can also activate your vagus nerve. Dr. Franklin says those moments of wonder help calm the nervous system. And don’t underestimate laughter either. A big belly laugh boosts heart rate variability-a sign of a healthy vagus nerve-and reduces stress hormones. So go ahead-watch a goofy comedy or those viral animal reels. Your body will thank you.

Boundaries are the nervous system’s best friend.
If you are constantly stressed, frazzled, and on edge, it’s not just about what you do to unwind but also about what you protect. That is where boundaries come in. They aren’t selfish; they are the survival tools for your nervous system.
When you set boundaries, you’re telling your brain, “We’re safe. We’ve got limits.” That calms your stress response before it ever gets triggered. Without boundaries, you’re wide open to constant demands, pings, messages, and chaos -and your nervous system stays stuck in fight-or-flight mode.

Tech Boundaries
Start with tech: Try logging off work emails at a certain hour or giving yourself screen-free time before bed. Your brain needs that break. Even one “no-social” morning a week can lower anxiety.
Work Boundaries
At work, protect your time: set hours, take your lunch break away from your desk, and don’t be afraid to say no when you’re maxed out. Every “yes” when you’re already stretched thin sends your nervous system deeper into burnout.
Personal Boundaries & Self-Care
In your personal life, treat self-care as a meeting that can’t be missed. That daily walk, those 15 minutes of reading, or that yoga session after work-lock it in. Take distance from the people who drain you, if needed. It’s not rude. It’s healthy.
Sleep as a boundary
And most importantly, protect your sleep. Shut off the noise, put the lights out, and give yourself a soothing pre-sleep routine. Your nervous system heals during sleep. Don’t shortchange it.
Boundaries give your brain a message it desperately wants to hear: “you’re safe now.” And that’s the first step to actually feeling calm again.
The Power of “Small and Daily”
You might wonder, when you’re drowning in big stress, if tiny habits really matter. The truth? They do. Think of your nervous system like a battery-and every deep breath, screen break, or walk outside is a little recharge.
These small daily actions may not seem life-changing in the moment, but over time, they build resilience. They help keep your system from burning out. Sure, sometimes you need a bigger reset-a break, a therapist, or a major lifestyle shift.
But don’t underestimate the steady power of everyday calm. You don’t have to escape your life to find relief. You can breathe better, move your body, set a boundary, or dance around the kitchen-and every one of those acts sends your nervous system a message: “You’re safe.” These practices create little pockets of peace, even on the busiest days.
Do enough of them, and you might find that you feel less tense, snap less often, and reconnect with that long-lost sense of ease. Stress isn’t going anywhere-but how your body deals with it? That can change.
Next time you feel fried, see it as a sign that your system is asking for care and you need to calm your nervous system. Then respond: breathe, laugh, unplug, say no, hug someone you love. Your nervous system works hard for you. Show it some love, and it’ll carry you through.
