Five Ways To Naturally Calm The Nervous System

Modern life has distanced us from natural calm, turning ‘stress’ and ‘dysregulation’ into everyday language. More people than ever feel on edge, wired and emotionally exhausted. As alcohol, cigarettes and energy drinks become go-to coping mechanisms, many are beginning to search for more natural ways to calm their nervous systems.

In this article, I’m going to break down the stress response system and share five science-backed ways to naturally calm your nervous system and reconnect with your natural calm.

The five ways to naturally calm your nervous system

Use the power of social connection: Research shows poor social relationships greatly increases your risk for poor health (1).
Use Nature To Calm Your Nervous System: Research consistently shows that walking in nature rather than urban ones shifts the nervous system away from a state of chronic ‘high alert’ toward calm (2).
Use Breathwork: The Manual Override for your Nervous System: By consciously slowing our breath, we send a “reverse signal” up to the brain, manually switching the body from “Alarm” to “All-Clear.” (3)
The Technology-Dopamine Connection: Reclaim your baseline to feel naturally calm. Smartphones provide fast low-effort reward which may lower our baseline dopamine levels contributing to fatigue, brain fog and low motivation. Technology can overstimulate the brains threat detection centres contributing to low-grade anxiety and stress (4 and 5).
Consider natural remedies to calm your nervous system: While lifestyle habits form the foundation of nervous system regulation, some targeted botanicals and supplements have been shown to promote calm and relaxation.

What is a dysregulated nervous system?

Allow me to introduce you to your nervous system - comprising the brain, spinal cord, and nerves. It is the ultimate data processor. Everyday, it filters and interprets billions of signals, an amount scientists estimate to be roughly 70,000 thoughts per day (1). To respond to this incoming load, the brain relies on the autonomic nervous system (ANS) to balance two distinct modes: the Parasympathetic (Rest, Digest and Recover) System and the Sympathetic System (Fight and Respond).

The Sympathetic Nervous System (our stress response system) relies on adrenaline, norepinephrine and cortisol to perform with acute and chronic stress (2). While the Sympathetic system is an evolutionary masterpiece, it is not meant to be left on. Think of it like the thermostat on a kettle; it’s essential for reaching a boil, but it must click off once the job is done to prevent overheating. Chronically elevated levels of cortisol can be corrosive. Over time, elevated HPA-axis (long-term stress response) activity can lead to irritability, overwhelm, brain fog, anxiety and depression. It can also lead to high blood pressure, high blood sugar, disrupted sleep, memory lapses and inflammatory disorders. It can also contribute to chronic fatigue and a feeling ‘tired and wired’ (3).

If the HPA-axis is working too hard over many months or years without rest, it can tip us into nervous system dysregulation and prevent us from easily accessing our default state of having a calm nervous system.

What is a calm nervous system?

In our modern “always-on” culture, you might often treat calm as a luxury or rare destination. In reality, calm is our biological default. It is our safety cue or our “neutral gear” required for us to move fluidly between various emotional and cognitive demands of the day (4). It is the neutral gear that allows our nervous system to comfortably oscillate between the parasympathetic and sympathetic modes.

We are often so busy and distracted by life and all the things we need to do, we’ve almost forgotten what it feels like to feel calm. Calmness is a ‘neutral’ state reflective of our feelings of safety. We want to be calm and alert as much as possible. If we are feeling like we are having to stress and strain to get through our day on a regular basis, it might be time to seek help.

As Dr Mosaraf Ali, states optimal health feels like:

Having sufficient amounts of energy.
A feeling of being unrestricted.
Sound sleep.
The ability to carry out duties without feeling strain or stress.
A clear focused mind and sharp short term memory.

Things that can trigger nervous system dysregulation:

Chronic stress (4)
Childhood or recent trauma (5)
Overtraining (6 and 7)
Chronic pain (8)
Unresolved emotional distress
Caffeine or stimulant overuse (9)

What are the signs of a dysregulated nervous system?

Nervous system dysregulation can manifest in multiple ways for different people but some typical signs include:

Feeling easily overwhelmed or irritable, you might feel like you can’t switch off, or you need to keep busy and might depend on caffeine or alcohol.
You might feel ‘tired and wired’ or have difficulty sleeping.
You might experience butterflies or changes to bowel habits, you might just have a subtle feeling of ‘things are not ok.’
You might struggle with motivation, mood swings or difficulty making decisions.

You might experience more severe physical symptoms such as racing heart, tightness in your chest, chronic fatigue or headaches. In any case, it’s very important to seek help from your GP or relevant healthcare professional.

The Brain’s Great Blind Spot: Perception vs. Reality

It is vital to remember that your brain cannot distinguish between a real threat and a perceived one. To prove it, just imagine biting into a lemon right now. Notice the zing of your tongue? Your mouth is likely watering, even though there isn’t a lemon in sight. Your brain sent a physical command based entirely on a thought.

The same mechanism is at play when your boss imposes a sudden, high-stakes deadline. Your nervous system doesn’t see a ‘spreadsheet’, it sees a tiger. It immediately triggers a cascade of adrenaline and cortisol, preparing you for a ‘life critical’ struggle.

Over time, this high alert state can become our default setting and I observe a combination of poor nutrition, environmental pollution, trauma and even low-grade viral activity keeping the volume turned up on our stress response long after the deadline has passed (10, 11, 12). The good news? Because this state is often ‘perceived’, we can re-train ourselves. We have the power to interrupt these signals and reinforce a baseline of safety and calm.

Five ways to naturally calm the nervous system

The next time you find yourself becoming dysregulated or stuck in a stressed state, try the following tips to naturally calm your nervous system.

Use the power of social connection to calm your nervous system.

If there was only one recommendation I could share to naturally calm your nervous system, it’s this: embrace the power of social connection.

We often think of loneliness as a private heartache, but it has become a global health priority. In 2018, the UK government even appointed a “Minister of Loneliness” to address the “loneliness recession” currently sweeping through modern society (14). We feel this recession deep in our biology. Think about the last time you had a grueling day, only to feel the tension melt away the moment you sat down with a close friend. That isn’t just a mood shift it’s your nervous system exhaling.

This happens because we are biologically hardwired for the “tribe”. To ensure survival, our brains developed “rejection software”- a system triggering intense distress and alarm when we feel disconnected. When this alarm stays on too long (chronic isolation or loneliness), the physical toll is staggering. Research shows poor social relationships can increase the risk of heart disease by 29% and stroke by 32% and isolation can increase the risk of dementia and death from all causes (15).

While we are still uncovering exactly how connection calms us, animal studies suggest that reconnecting with people we recognise and trust triggers the release of serotonin (16, 17). This doesn't just make us happy; it signals "safety and satiety” for our nervous system. This surge of serotonin simultaneously mutes stress hormones like adrenaline and cortisol while inhibiting Tachykinins- the chemicals that promote fear and paranoia (18). In short: connection tells your body it is safe to power down our sympathetic nervous system helping us feel calm.

While there is beauty in solitude, chronic isolation is a biological red flag. We evolved to find safety in numbers, and our bodies are designed to reward us when we find our way back to our group.

Here are some quick ways to quickly harness more social connection if you’re feeling a spike in anxiety, try these four strategies to “hack” your biology and signal to your brain that you are safe.

i) Upgrade from Text to Video

Text-based communication is convenient, but it often lacks the sensory nuance required to trigger your parasympathetic (calm) nervous system. When you’re stressed, try switching to a video call. Seeing a face activates mirror neurones, allowing you to “sync up” with your friend’s calm energy more easily. Recognising micro-expressions and hearing a familiar tone proves the “safety signal” your brain needs to inhibit the amygdalae (the brain’s fear centers) and drop your nervous system into calm and ease.

ii) Use “Social buffering” (even while working)

You don’t have to be deep in conversation to benefit from others. Research shows that simply being in the presence of people can dampen your stress response- a phenomenon known as social buffering.

Try this: Join a co-working space or co-working Zoom group where everyone works silently with cameras on. If you’re in an office, move your deep-work session to a communal lounge rather than staying behind a closed door.

Why it works: Physical proximity (even virtual) signals your HPA-axis that you are not alone. You are moving your nervous system from “high alert” to “safe group mode”.

iii) Value “Social snacking”

We often think that only deep conversations with long-time friends “count” as connection. But for a busy professional, neglecting your “weak ties”, those brief interactions with people outside your inner circle is a missed opportunity for regulation.

Try spending just 30 seconds chatting with your receptionist, barista, security guard or somebody on the plane. These low-pressure moments increase our social integration acting as a “micro-dose” of belonging, reminding your brain that you are part of a wider, safe community. And you might just make a new friend.

iv) Express, Don’t Suppress

In high-stress fields like healthcare or education, carrying the weight of the day in silence isn’t just difficult-it’s a leading cause of burnout. We often think “toughing it out” is the path to resilience, but research shows the opposite: verbalizing your experience is one of the strongest predictors of long-term health (19). Studies have shown verbalising pain increases our ability to withstand it, a.k.a resilience (20).

You don’t need a therapist on speed dial; you just need one “safety peer.” Try establishing a protocol where you can call or send a 1-minute voice note to vent about a stressor. It’s not about the recipient offering solutions; they are simply there to witness it. The nervous system is often calmed more by the knowledge that support is available than by the actual support itself. Just knowing you have a safe place to “dump” your stress prevents the amygdala from staying in a state of chronic alarm.

Use Nature To Calm your Nervous System

While social connection provides ‘safety in numbers’ the physical environment provides the ‘safety signals’ our brains evolved to recognise long before cities existed. Research consistently shows that walking in nature rather than urban ones shifts the nervous system away from a state of chronic ‘high alert’ toward calm (21).

Why your brain prefers the trees

As neuroscientists, we are still uncovering exactly why nature is so potent to calm the nervous system, but current research points to a shift in attentional states. Walking in nature, allows the brain to switch from an ‘explicit, effortful’ state towards passive attention. Nature captures our attention without effort, providing the mental space needed for the nervous system to downshift.

Compared to urban environments, nature walks are scientifically linked to:

Neural Quiet: Less negative rumination and lower emotional reactivity (21).
Chemical Balance: Reduced stress hormone overload and anxiety (22.
Cognitive Recovery: Improved mindfulness, clearer thinking, and a sense of optimism (23).

In the words of the research, “Nature gives the brain fewer stress cues and more restorative cues, helping interrupt repetitive thought loops.”

The “Nervous System Reset” Walk

To get the most out of your time outside, treat your walk as a biological ‘reset’ rather than a fitness goal.

Ditch the Tech: Leave the smartphone at the office. Allow your brain to process the ambient sounds of wind, water or birds.
The “Slow & Soft” Technique: Walk slower than your usual “commuter pace.” Soften your gaze, don’t stare at your feet; let your eyes take in the colour and horizon.
Frequency Over Intensity: Consistency is your best friend. A 15-minute walk 3-5 times a week is often more regulating for the nervous system than one long hike once a week.

Breathwork: The Manual Override for your Nervous System

“Breathwork” has become a wellness buzzword, but beneath the trend lies a profound biological reality: your breath is the only part of your autonomic nervous system that you can consciously control. It is your built-in remote control for stress.

The Bi-Directional Relationship

Our heart and lungs are intimately connected to our threat-detection centres and autonomic nervous system. If you were confronted by a predator, your brain would instantly signal your lungs to gasp and your heart to race. This relationship is a two-way street. By consciously slowing our breath, we send a “reverse signal” up to the brain, manually switching the body from “Alarm” to “All-Clear.”

The Vagus Nerve: Your Inner Peace Highway

At the centre of this process is the Vague Nerve- the longest nerve in the body. It acts as a high-speed fiber-optic cable, sending safety signals that lower your heart rate, stimulate digestion, and can help regulate inflammation (24). By harnessing slow, deliberate breathing, you improve vagal tone, effectively strengthening your nervous system’s ability to calm stress, anxiety and aiding sleep (25).

Exhale to Relax

Research shows that exhalation-dominant patterns are most effective for calming anxiety, stress, lowering cortisol levels and even lowering blood pressure (26, 27, 28).

Box Breathing: Used by Navy SEALs to maintain calm under pressure.
The 4-7-8 Method: Developed by Dr Andrew Weil, this specific rhythm acts as a natural tranquilizer for the nervous system.
SKY Breathing: One of the most researched techniques across multiple conditions including depression, stress and PTSD.

How often should I practice breathwork to calm my nervous system?

The research suggests at least 30 minutes per day but even short daily sessions of 10-15 minutes can lead to significant benefits when you maintain the habit.

The Technology-Dopamine Connection: Reclaim your baseline to feel naturally calm

Jeff Bezos famously said, “Stress arises from the things we haven’t done.” In our digital age, we are constantly tethered to devices that fragment our attention and offer artificial rewards. This creates a “high-stimulation, low-reward” environment that keeps the nervous system in a state of chronic, low-level stress.

By cultivating more proactive habits with technology, you can move from a state of reactive exhaustion to one of proactive calm.

i) Avoid the “Dopamine Debt” to stay naturally calm

Checking your smartphone the moment you wake up spikes your dopamine levels artificially. While this provides a temporary ‘hit’, it inevitably leads to a dopamine debt later in the day, manifesting as brain fog, irritability and a lack of motivation helping drive frustration and stress (29 and 30). By delaying smartphone use for the first 60-90 minutes of the day and engaging in effortful work first, you prevent this artificial ‘spike and crash’, allowing your nervous system to remain steady, calm and focussed.

ii) Embrace the “Boredom Reset”

Boredom is actually a biological signal that your brain is ready to seek out a new, meaningful goal. When we soothe boredom with our screens, we deprive our brain of its natural reset period. Simple acts like walking to grab a coffee without your phone facilitate the brain state required for creativity, problem solving and emotional processing. By installing healthy boundaries with your device and embracing moments of stillness, you give your nervous system the space it needs to recalibrate resulting in more natural calm (31).

iii) Anchor your day with Movement

Physical movement, especially in the morning, sets a healthy neurochemical tone for the next 12 hours. Unlike ‘cheap’ dopamine from a screen, movement triggers a measured, gradual release of important neurotransmitters like Serotonin, Dopamine, Oxytocin and Endorphins. Because these chemicals are ‘earned’ through effort, they support sustained concentration, allowing steady productivity while remaining calm (32).

Supplements to help calm your nervous system

In the midst of a busy work schedule, herbs and botanicals can be a very helpful tool to naturally calm the nervous system. While lifestyle habits form the foundation of nervous system regulation, targeted botanicals and supplements can be powerful allies. These “adaptogens” and compounds help the body maintain equilibrium in the face of chronic stress.

A range of herbs and botanicals have been shown to reduce chronic stress and anxiety. These include Ashwagandha, L-theanine, Rhodiola Rosea, Passion Flower, Cordyceps Sinesis, Lions Mane and Bacopa Monieri.

Ashwagandha: Often called ‘Indian Ginseng’, this Ayurvedic staple is one of the most researched adaptogens available. Studies show that dosages between 100 to 600mg (typically root extract) can significantly reduce cortisol levels, helping the body ‘buffer’ against anxiety and stress (33, 34, 35, 36, 37, 38).

L-theanine: Found naturally in green and black tea, this amino acid works by blocking glutamate receptors and increasing Alpha-wave activity- the same restorative brain state we achieve through deep breathwork (39 and 40). It has been shown to improve cognitive performance under stress while lowering the physiological markers of anxiety (41, 42).

Rhodiola rosea: Has been traditionally used for stress and fatigue reducing effects, but it may also have antidepressant properties. Although its mechanisms are unknown, a 600mg dose per day showed improved cognitive performance (40) and anti-fatigue effect (43).

Passionflower: Traditionally used as a calming and sedative agent by herbalists. Passionflower has been trialled against benzodiazepines in supporting anxiety and insomnia and comparing fairly well (44 and 45).

Bacopa monnieri: or water hyssop is commonly used in Ayurvedic medicine and used to improve cognitive function and relieve stress and anxiety (46, 47).

Phosphatidylserine: is a lipid component of our cell membranes and can also be a wonderful tool to regulate the HPA-axis.

My Final Thoughts

Ultimately, calming your nervous system is about returning to your roots-tapping into a deeply encoded human need for safety and connection. Calm is not a complex mystery, but a practice of returning to the basics: embracing the people around you, immersing yourself in the natural world, mastering the rhythm of your breath, and occasionally leaning on the support of botanical remedies. When you downshift out of survival mode and return your system to ‘neutral’, you do more than just reduce stress; you reclaim the space to be your most authentic, creative and dynamic self.
