Understanding the Vagus Nerve and How to Manage Stress
The damaging effects of chronic stress on physical and emotional health are much talked about in the media, and deeply felt by many of us in our daily lives in the form of sleep issues, high blood pressure, auto immune and chronic pain conditions, anxiety, irritability and even obesity. But did you know…? Within each of us is a silent hero who plays a significant role in regulating our body's response to stress and harnessing its power could be the key to a truly stress-free future and it is something you can take control of.
The vagus nerve, also known as the "wandering nerve," is the longest cranial nerve in the body, running from the brainstem to the abdomen. It plays a crucial role in regulating various bodily functions, including heart rate, digestion, and even mood. However, it's perhaps most renowned for its role in the body's stress response system.
When we experience stress, whether it's from work, relationships, or other external factors, our sympathetic nervous system kicks into high gear, triggering the body's fight-or-flight response. This response is essential for survival in threatening situations, but when stress becomes chronic, it can wreak havoc on our health and well-being.
Here's where the vagus nerve comes into play. This remarkable nerve acts as the body's built-in calming mechanism, counteracting the stress response by activating the parasympathetic nervous system, often referred to as the "rest and digest" system. By stimulating the vagus nerve, we can help dampen the body's stress response and promote a sense of calm and relaxation.
So, how can we harness the power of the vagus nerve to manage stress effectively? Here are five simple tips to help you do just that:
1. Deep Breathing Exercises
Deep breathing techniques, such as diaphragmatic breathing or the 4-7-8 technique, can help stimulate the vagus nerve and activate the parasympathetic nervous system.
Take slow, deep breaths, focusing on filling your abdomen with air, then exhale slowly and completely. Repeat this for a few minutes whenever you feel stressed or overwhelmed.

2. Humming or singing
Humming and singing create vibrations in the back of the throat and chest that in turn, stimulate the vagus nerve. So, turn up the radio and belt out your favourite rock ballad or just hum along as you drive and it will all help reduce your stress levels.
3. Laughter
Laughter really is the best medicine when it comes to stress reduction. Watch a funny movie, spend time with friends who make you laugh or do something that brings you joy. Laughter has been shown to increase heart rate variability; a marker of vagal tone.
4. Spend Time in Nature
Spending time outdoors, surrounded by nature's beauty, can have a calming effect on the nervous system and help stimulate the vagus nerve. You don’t have to wait until the weekend though – try drinking your morning coffee stood in the back garden (and get some of that important morning light too), take a lunchtime walk around a local park or just spend a few moments appreciating a beautiful vase of flowers or houseplant.
5. Gratitude Practice
Cultivate a daily gratitude practice by reflecting on the things you're thankful for. Expressing gratitude has been shown to enhance vagal tone and promote emotional well-being.
Don’t Let Stress Lead Your Life
While stress may be an inevitable part of life, it doesn't have to overpower us. By understanding the role of the vagus nerve in regulating our body's stress response and implementing simple strategies to stimulate it, we can effectively manage stress and cultivate a greater sense of calm and well-being in our lives. So, the next time you're feeling stressed, remember to take a deep breath, hum along to the radio, seek out that latest funny cat video, connect with nature, and practice being grateful for what you have – your vagus nerve will thank you for it.
