Restoring Balance - Understanding Stress and Supporting Your Nervous System
How balanced does your life feel right now?
And perhaps more importantly, how balanced does your body feel?
Stress has become so normalised in modern life that many of us no longer recognise when it’s quietly shaping our health, energy, digestion, sleep and emotional wellbeing. In this blog, we want to help you understand stress from a functional medicine perspective, and empower you with simple, supportive ways to restore balance and resilience.
Because stress isn’t just “in your head”, it’s biological, chemical and very much connected to how your nervous system functions every single day. It’s shaped by your environment.
Stress in the Modern World - Your Body on Constant Alert
We live in a world where we are almost constantly responding to perceived threat, and not necessarily physical danger, but emotional, mental and sensory overload.
Social media notifications, WhatsApps, emails, deadlines, news headlines, financial pressure, relationship dynamics, traffic, poor sleep and being contactable 24/7 all signal to the body that it needs to stay alert.
The result? Many of us are spending the majority of our waking hours in a low-grade stress response, something our biology was never designed for.
In ancestral times, stress was acute and short-lived. Once the threat passed, the body returned to balance. Today, we often experience more nervous system stimulation in a single day than our ancestors would have experienced in an entire year. Our stress response system wasn’t designed for chronic stress, however low-grade it might be.
Stress & Your Nervous System - Why It Matters
To understand how stress impacts your health, it’s helpful to understand the autonomic nervous system (ANS), the part of the nervous system that controls involuntary processes such as heart rate, digestion, blood sugar regulation, immune activity and hormone release.
The ANS has two main branches:
1) The Sympathetic Nervous System (SNS) also called “Fight or Flight”
This is your stress response system. It’s designed to protect you in moments of danger by:
Increasing heart rate and blood pressure
Raising blood glucose for quick energy
Releasing adrenaline and cortisol from the adrenal glands
In the short term, this response is essential. But when it’s constantly switched on, it becomes draining and inflammatory.
2) The Parasympathetic Nervous System (PNS) also called “Rest & Digest”
This is your healing and restorative state. It supports:
Digestion and nutrient absorption
Immune function
Hormone balance
Tissue repair and regeneration
Deep, restorative sleep
For optimal health, we need regular daily access to this state.
What Happens When Stress Becomes Chronic?
When we spend too much time in fight-or-flight and not enough time in rest-and-digest, the body starts to adapt, but at a cost.
Chronic stress:
Depletes key nutrients such as magnesium, B vitamins, vitamin C and zinc
Keeps cortisol elevated, disrupting blood sugar, sleep and energy
Suppresses digestion, immunity and reproductive hormone signalling
Increases inflammation in the body
Over time, this can contribute to:
Feeling “tired but wired”
Difficulty switching off at night
Digestive discomfort or bloating
Frequent illness
Anxiety, low mood or irritability
Burnout and chronic fatigue
Your body isn’t faulty, it’s doing its best to survive.
Your Nervous System Wants Balance
What’s great is that your nervous system is incredibly adaptable and it wants to return to balance.
The goal isn’t to eliminate stress, it’s to:
Reduce unnecessary stress load
Actively support the parasympathetic nervous system
Replenish nutrients used up during stress
This is where functional medicine and nourishment play a powerful role.
Nourishing the Stress Response - Key Nutrients
Magnesium: The Calming Mineral
Magnesium is one of the most commonly depleted nutrients during stress. It helps:
Calm the nervous system
Relax muscles
Improve sleep quality
Regulate stress hormones
Food sources include: Dark leafy greens, nuts and seeds, beans, oats and buckwheat.
Magnesium glycinate is a well-researched supplemental form for nervous system support.
B Vitamins (Especially B5)
B vitamins are essential for energy production and adrenal function.
Vitamin B5 (pantothenic acid) plays a key role in:
Supporting cortisol balance
Energy production
Blood sugar regulation
Healthy blood pressure
Food sources include: Eggs, salmon, liver, whole grains, mushrooms, leafy greens, nuts and seeds.
Activating Rest & Digest - Daily Practices That Make All The Difference
You can gently switch on your rest-and-digest state through simple, nourishing practices such as:
Deep breathing
Meditation and mindfulness
Yin or restorative yoga
Tai Chi or Qi Gong
Walking in nature
Journaling
Short naps or intentional rest
Even a few minutes at a time sends a powerful safety signal to your nervous system.
Simple Habits That Build Stress Resilience
Here are some of our favourite stress-relieving and resilience-building habits:
Walking in green spaces
Mindful movement (yoga, Pilates, Tai Chi, Qigong)
Gentle breathing techniques (4:6 or 4-7-8 breathing)
Guided meditations (Calm, Headspace, Insight Timer)
Gratitude practice
Laughter
Hugs with loved ones or pets
Listening to music you love
Epsom salt baths with lavender
Moderate resistance training
Gentle cardio (walking, swimming, cycling)
5–30 minutes a day, done consistently, can have a profound impact on how your body experiences stress.
Bringing This All Together
Stress is an intuitive, biological response to modern life.
When you support your nervous system with nourishment, movement, rest and intentional pauses, you create the internal environment needed for energy, balance and resilience to return, and for you to feel so much better day to day.
