Meet the Vagus Nerve
The state many people are living in is not acute stress, rather it’s fatigue that doesn’t resolve with sleep. Digestion that fluctuates. A sense of being “on” at night and slow to start in the morning. Energy that spikes and drops instead of holding steady.
Sound familiar?
This is often a nervous system that hasn’t fully shifted out of sympathetic dominance—a low-grade, persistent stress state. And at the center of that regulation is the vagus nerve.
What the vagus nerve does
The vagus nerve is a major pathway connecting the brain to the body—particularly the gut, heart, and lungs.
It governs the parasympathetic nervous system, often referred to as “rest and digest.” This system is responsible for:
- Slowing heart rate
- Stimulating digestion
- Regulating inflammation
- Supporting recovery and repair
Vagal tone describes how effectively this system responds. Strong tone allows the body to move in and out of stress appropriately. Low tone can leave the body stuck in activation, even when rest is needed.
Restoration of your vagal tone isn’t about eliminating stress—it’s about restoring range. Below we share a 4-prong approach.
Vegal Tone restoration
1. Vagus nerve Stimulation
One thing to focus on when working with vagal tone restoration is simple, direct stimulation of the vagus nerve:
- Breath work A 4-second inhale, 6-second exhale pattern encourages parasympathetic activation
- Gargling Engages muscles connected to the vagus nerve and supports the migrating motor complex (MMC), important for digestion
- Humming or chanting Vibrational stimulation of vagal pathways
- Cold exposure (face immersion) Activates a reflex that slows heart rate and promotes calm
These are low-effort, high-frequency tools. And remember, consistency matters more than intensity. Always.
2. Circadian rhythm
Vagal tone doesn’t operate in isolation—it’s deeply tied to circadian rhythm, which is regulated by the hypothalamus. When circadian signals are off, the nervous system struggles to regulate.
Another focus when regulating vagal tone are these key circadian rhythm anchors:
- Morning light exposure 20–30 minutes of natural light shortly after waking helps set the body’s internal clock, supporting cortisol rhythm, energy, and HPA axis function.
- Midday sunlight 10–20 minutes supports vitamin D production, mitochondrial function, and metabolic health.
- Evening light control Reducing blue/green light after sunset protects melatonin production and sleep quality. Dim lighting, red light, or blue-light blockers can help.
- Consistent sleep (wake timing) Regularity reinforces circadian signaling and improves stress regulation.
3. Eating, movement, and timing
The body responds not just to what you do, but when you do it.
- Eat during daylight hours, ideally with a larger meal earlier in the day
- Have breakfast within 1–2 hours of waking to reinforce hormonal signaling
- Emphasize protein-rich, nutrient-dense foods
- Align movement with energy patterns—midafternoon is often optimal, though consistency matters more (always ;-)
These quotidian patterns support insulin sensitivity, digestion, and energy stability, all of which feed back into nervous system regulation.
4. Stress, inputs, and seasonal shifts
Chronic stress, whether physical or psychological, keeps the nervous system activated. Support can include:
- Breathwork and meditation
- Massage and bodywork
- Time outdoors and grounding
- Infrared sauna or light therapies
- Ongoing vagal stimulation practices
Seasonally, adjustments matter. Shorter days require more intentional light exposure, warming foods, and potentially supplementation (like vitamin D) to maintain balance.
A note on measurement
For those looking deeper, tracking markers like cortisol, melatonin, thyroid hormones (TSH, T3, T4), and other metabolic indicators can offer insight into how well circadian and stress systems are functioning.
As we like to say: Don’t guess, TEST! Jelena is available to consult, support and provide bio-marker testing, through Acupuncture and Functional Medicine.
TL:DR
Vagal tone restoration isn’t one practice—it’s a pattern.
Light exposure. Meal timing. Breath. Small, repeated signals that tell the body when to activate and when to rest.
Over time, the goal is simple:
a system that can shift, recover, and regulate—without effort.
