Our modern, fast-paced lives have made stress an unavoidable component, and it has a significant impact on both our physical and emotional health. The vagus nerve, a central nerve that is important in controlling numerous bodily activities, is an essential part of our body’s stress response system. 

The vagus nerve, commonly called the “wandering nerve,” regulates several bodily functions, including heart rate, digestion, mood, and immune response. The vagus nerve can be negatively impacted by long-term or extreme stress, which can have harmful effects on several physiological systems. 

In this article, we’ll look at typical ways stress can affect the vagus nerve and practical techniques to fight against those effects. 

How Stress Affects Your Vagus Nerve

Stress is unavoidable, and understanding how it impacts your vagus nerve is important. Have a look at the nine ways or symptoms of how stress affects your Vagus Nerve.

Reduced Vagal Tone

Decreased vagal tone, which reduces the vagus nerve’s functionality, might result from ongoing stress, which may be a symptom you should focus on more. Inconsistencies in the heart rate, blood pressure, and digestion may result from this and maybe something you should look upon.


An inflammatory response brought on by stress can have an immediate effect on the vagus nerve. The vagal function can be hampered by inflammation, which also plays a role in other health problems. And hence, looking out for any possible inflammation is better.

Gastrointestinal Issues

Stress can impair digestive processes by preventing the vagus nerve from stimulating digestive enzymes and promoting healthy gut function. Simply put, you may have digestive issues, which can be detrimental. This may result in problems including bloating, indigestion, and irritable bowel syndrome (IBS).

Sleep Disturbances

Stress can disrupt the vagus nerve’s control of the sleep-wake cycle, making it harder to fall asleep or stay asleep for the duration of a healthy sleep. A lack of sleep makes stress levels even worse, creating a vicious cycle. Hence, if you feel that you are sleeping too much or too little, you should pay attention to that pattern.

Mood and Anxiety Disorders

The vagus nerve is essential for controlling mood and emotions. Chronic stress can disrupt vagal function, causing anxiety disorders, depression, and other mood-related illnesses to develop or worsen. Such issues can cause extreme distress and be fatal for anyone. Experts always recommend to have proper care when it comes to reducing the impact from your vagus nerve caused by stress by stimulators or as such for long-term benefits. You can also look into transcutaneous vagus nerve stimulators to have more ideas. TVNS has been investigated for a variety of conditions, including depression, anxiety, chronic pain, and epilepsy, and has shown promising results in some studies. Overall, TVNS is a relatively safe and non-invasive method of neuromodulation that has potential therapeutic benefits for various health conditions.

Weakened Immune Response

Long-term stress can reduce immune system activity, which affects the vagus nerve’s capacity to control immunological response and inflammation. People may become more prone to infections and other illnesses as a result of this.

Cognitive Impairment

Memory, concentration, and decision-making skills are all affected negatively by stress. Due to the vagus nerve’s function in controlling brain activity, stress-related vagal dysfunction might result in cognitive deterioration.

Respiratory Issues

Stress can interfere with the vagus nerve’s modulation of respiratory function. People who are stressed out may experience shallow breathing, fast breathing, or even hyperventilation, which can worsen their symptoms.

Reduced Relaxation Response

Stress prevents the vagus nerve from starting the relaxation response, which results in ongoing tension, restlessness, and a lack of capacity to relax. So if you find yourself fidgeting or restless, it can be a symptom of stress affecting your vagus nerve.

What to Do About It

Now that we have looked into various symptoms of how stress affects your vagus nerve, we can move on to various methods that you can adopt to mitigate the issue and have better health in general!

Practice Stress Management Techniques

Use stress-relieving techniques such as deep breathing exercises, yoga, meditation, or mindfulness techniques to improve vagal tone and trigger the relaxation response.

Get NAD Therapy

NAD Therapy is the process of delivering Nicotinamide adenine dinucleotide (NAD) through IV infusion so the nutrients totally bypass the digestive system and enter straight to the bloodstream to be used immediately by the cells that need it.NAD is an enzyme that is essential for numerous metabolic processes and NAD therapy has benefits such as improving cognitive function, helping combat anxiety and depression and most importantly, aiding in chronic stress management.” 

Exercise Regularly

It has been demonstrated that exercise improves vagal tone and lessens stress. Therefore, participate in enjoyable activities, such as dancing, walking, or any other exercise that meets your interests and capabilities.

Get Sufficient Sleep

Establish a regular sleep schedule, a calming nighttime routine, and a sleeping-friendly environment to prioritize great sleep. This lessens stress and aids in the restoration of vagal function.

Adopt Healthy Eating Habits

Eat a healthy, balanced diet of fresh produce, whole grains, and lean proteins. Limit your intake of sugar, caffeine, and processed foods because these can cause inflammation and interfere with vagal function.

Foster Social Connections

Develop helpful connections with others and spend time with your loved ones. Positive social contacts and social support have been demonstrated to improve vagal tone and lessen stress.

Engage in Mindfulness Practices

Use mindfulness in your regular activities to stay present and lower your stress levels. This can involve exercises in body scanning, journaling about thankfulness, or mindful eating.

Seek Professional Help

Consider speaking with a medical practitioner or therapist if stress and its effects on your vagus nerve significantly affect your daily life. They can offer you advice, assistance, and specialized treatments in accordance with your needs.

Prioritize Self-Care

Give yourself some time to engage in things that are good for your body, mind, and spirit. This can be indulging in hobbies, relaxing techniques, enjoyable activities, or walking our pet.


Sustaining our general well-being requires an awareness of how the vagus nerve is impacted by stress. The vagus nerve, essential for controlling many biological processes, can suffer from prolonged or severe stress, which can negatively impact our physical and mental health.

Fortunately, some useful methods and approaches can lessen the damaging effects of stress on the vagus nerve. And we hope the methods mentioned above will aid you in reducing the impacts caused by stress in your vagus nerve.
