Looking After Your Vagus Nerve
Simple, Evidence-Informed Ways to Support Your Body’s Natural Relaxation Response
The vagus nerve is the longest cranial nerve in the body and plays an important role in regulating many automatic functions, including breathing, heart rate, digestion, inflammation, and our ability to rest and recover.
Rather than trying to “strengthen” the vagus nerve, it is more accurate to think about supporting healthy vagal function. Research suggests that lifestyle habits promoting good physical and emotional health also encourage a healthy balance between the sympathetic (“fight or flight”) and parasympathetic (“rest and digest”) nervous systems.
While no single technique works for everyone, the following approaches have the strongest evidence for supporting overall vagal function.
1. Slow, Controlled Breathing ⭐⭐⭐⭐⭐
One of the most effective ways to stimulate the parasympathetic nervous system.
Aim for:
● Slow breathing (around 5–6 breaths per minute)
● Breathe into the lower ribs rather than lifting the shoulders
● Make the exhale slightly longer than the inhale
Example:
● Inhale for 4 seconds
● Exhale for 6 seconds
● Continue for 5–10 minutes
Benefits may include:
• Reduced stress response
• Improved heart rate variability (HRV)
• Greater sense of calm
• Better emotional regulation
2. Regular Physical Activity ⭐⭐⭐⭐⭐
Exercise is consistently associated with healthier autonomic nervous system function.
Good options include:
● Walking
● Swimming
● Cycling
● Yoga
● Pilates
● Tai Chi
● Strength training
Aim for at least 150 minutes of moderate activity each week.
3. Prioritise Good Sleep ⭐⭐⭐⭐⭐
The nervous system recovers during sleep.
Helpful habits include:
● Consistent bedtime
● Morning daylight exposure
● Limiting caffeine later in the day
● Keeping the bedroom cool and dark
● Reducing screen time before bed
Adults generally need 7–9 hours each night.
4. Build Positive Social Connections ⭐⭐⭐⭐☆
The vagus nerve is closely linked with social engagement.
Helpful ideas include:
● Spend time with supportive friends
● Laugh regularly
● Maintain eye contact during conversations
● Join community activities
● Volunteer
● Spend time with family
Positive relationships are associated with improved emotional wellbeing and healthier autonomic regulation.
5. Mindfulness and Meditation ⭐⭐⭐⭐☆
Regular mindfulness practice has been shown to reduce stress and may improve markers of vagal activity.
Even 10 minutes daily can be beneficial.
Options include:
● Mindfulness meditation
● Body scan
● Loving-kindness meditation
● Guided relaxation
6. Gentle Touch and Therapeutic Bodywork ⭐⭐⭐⭐☆
Supportive touch may encourage relaxation and help reduce sympathetic nervous system activity.
Many people report feeling calmer following gentle complementary therapies.
Examples include:
● Massage
● Gentle manual therapy
● Relaxation-focused bodywork
● The EMMETT Technique
● Reflexology
Although more research is needed to determine the specific effects of different therapies on vagal activity, many people experience improved relaxation and wellbeing after treatment.
7. Spend Time in Nature ⭐⭐⭐⭐☆
Research shows that spending time outdoors may reduce stress hormones and improve mood.
Try to:
● Walk in a park
● Visit woodland
● Sit near water
● Garden
● Observe wildlife
Even 20 minutes can make a difference.
8. Eat for Gut Health ⭐⭐⭐⭐☆
The vagus nerve forms an important communication pathway between the gut and the brain.
Support gut health by:
● Eating plenty of vegetables
● Including fruit daily
● Choosing whole grains
● Eating fermented foods if suitable
● Staying well hydrated
● Limiting highly processed foods
A diverse diet helps support a healthy gut microbiome.
9. Stay Hydrated ⭐⭐⭐☆☆
Even mild dehydration can increase physical stress on the body.
Aim to drink water regularly throughout the day.
10. Singing, Humming and Chanting ⭐⭐⭐☆☆
The vagus nerve supplies muscles involved in the voice.
Activities such as:
● Singing
● Humming
● Chanting
● Gentle vocal exercises
may promote relaxation in some people, although evidence is still developing.
11. Gargling ⭐⭐☆☆☆
Some clinicians suggest gentle gargling as a way of activating muscles supplied by the vagus nerve.
Evidence is currently limited, but it is generally safe for most healthy adults.
12. Cold Water Exposure ⭐⭐☆☆☆
Brief facial exposure to cool water or finishing a shower with cool water may activate reflexes involving the vagus nerve.
This should be approached cautiously and avoided if you have certain heart conditions or if advised by your healthcare professional.
13. Reduce Chronic Stress ⭐⭐⭐⭐⭐
Persistent stress can keep the body in a prolonged “fight or flight” state.
Helpful strategies include:
● Taking regular breaks
● Spending time outdoors
● Gentle exercise
● Relaxation techniques
● Talking with supportive people
● Seeking professional help when needed
14. Healthy Blood Sugar Balance ⭐⭐⭐⭐☆
Large fluctuations in blood sugar may place additional stress on the body.
Consider:
● Regular meals
● Adequate protein
● Fibre-rich foods
● Limiting excessive refined sugar
15. Support Emotional Wellbeing ⭐⭐⭐⭐☆
Managing emotional health supports overall nervous system resilience.
Helpful options include:
● Counselling
● Journalling
● Gratitude practice
● Creative hobbies
● Time with loved ones
What Doesn’t Have Strong Evidence?
Many websites claim you can “reset” or “tone” the vagus nerve quickly.
Current research does not strongly support claims that any single exercise, supplement, gadget, or therapy can dramatically “fix” vagus nerve function overnight.
Healthy vagal function appears to be supported by consistent lifestyle habits rather than one specific intervention.
Everyday Vagus Nerve Checklist
☐ Take five slow breaths
☐ Move your body
☐ Spend time outdoors
☐ Drink enough water
☐ Eat colourful whole foods
☐ Connect with someone
☐ Laugh or smile
☐ Get good sleep
☐ Practise mindfulness
☐ Enjoy activities that help you relax
Final Thoughts
The vagus nerve is one of the body’s key communication pathways, helping coordinate relaxation, recovery, digestion, and emotional regulation. Looking after your overall health—through movement, sleep, nutrition, stress management, positive relationships, and appropriate therapeutic support—is one of the best ways to encourage healthy vagal function.
Healthy habits practised consistently are likely to have a greater impact than searching for a single “quick fix.”
