The vagus nerve is part of your “When you’re stressed or scared, your heart rate and blood pressure increase, and you become focused on survival,” Dr. Lin explains. “Being in that stressful ‘fight-or-flight’ state can wear out your body. The parasympathetic nervous system and vagus nerve bring you back to a stable state when the stress is over.” In other words, your What is the connection between your vagus nerve and anxiety? During a state of danger, The problem is that the fight-or-flight response doesn’t know the difference between immediate danger and life stresses that come at us every day. Imagine this: You’re an early human. You spot a tiger in the woods that’s about to pounce. Your sympathetic nervous system kicks in and you prepare to (somehow) fight off the tiger. Then, the tiger wanders off. And then your body downshifts from the stress of almost being eaten. That’s what the sympathetic nervous system is for. To prepare us to fight for our lives (or find a way to...

When refering to evidence in academic writing, you should always try to reference the primary (original) source. That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references.

In previous posts we described the functions of the vagus nerve, how to care for it, how to stimulate and how it might get damaged. In this post we look in a bit more detail at some of the symptoms of vagus nerve damage and dysfunction. If you haven’t already done so, you can take our If you’re wondering whether you have some kind of vagus nerve dysfunction, this post will give you some idea of what you should be looking out for. None of this constitutes medical advice and even if something sounds like it fits, you should always talk to your doctor about it. The vagus nerve is the longest of your cranial nerves. It exits the brain on the right and left of the brain stem which is situated in the middle of the back of your skull, slightly below the level of the ears. It branches up to the ear and also down through your neck and all the way down to your intestines at the bottom of your torso. It visits all your major organs — the heart, lungs and stomach — as well as your throat and ears. Because of the wide ranging reach of the vagus nerve, the symptoms you might experience from low vagal tone are very broad, affecting many parts of the body. Also, because over 70% of the vagus nerve fibres carry sensory information back to the brain, it’s activity can have strong psychological effects, driven greatly by the gut-brain connections. We’ve tried to break up the symptoms we describe into broad categories affecting different parts of your body or mind. 1. Cervical (the neck regio...

The vagus nerve is the longest and most complex of the 12 pairs of cranial nerves that emanate from the brain. It transmits information to or from the surface of the brain to tissues and organs elsewhere in the body. The name “vagus” comes from the Latin term for “wandering.” This is because the vagus nerve wanders from the brain into organs in the neck, chest, and abdomen. It is also known as the 10th cranial nerve or cranial nerve X. Share on Pinterest The vagus nerve is one of the cranial nerves that connect the brain to the body. The There are multiple nervous system functions provided by the vagus nerve and its related parts. The vagus nerve functions contribute to the autonomic nervous system, which consists of the parasympathetic and sympathetic parts. The nerve is responsible for certain sensory activities and motor information for movement within the body. Essentially, it is part of a circuit that links the neck, heart, lungs, and the abdomen to the brain. What does the vagus nerve affect? The vagus nerve has a number of different functions. The four key functions of the vagus nerve are: • Sensory: From the throat, heart, lungs, and abdomen. • Special sensory: Provides taste sensation behind the tongue. • Motor: Provides movement functions for the muscles in the neck responsible for swallowing and speech. • Parasympathetic: Responsible for the digestive tract, respiration, and heart rate functioning. Its functions can be broken down even further into seven categor...

• The vagus nerve is important in managing heart rate, breathing, and digestion. • Damage to the vagus nerve can lead to a wide range of health conditions, including fainting and digestive issues. • Electrical impulses and other natural methods (like breathing and meditating) can help stimulate the vagus nerve. Lately, thousands of people on social media have been claiming one nerve in your body, called the vagus nerve, is connected to a slew of health conditions like anxiety, depression, heart disease, and autoimmune disorders.

According to Weller, evidence is growing that the vagus nerve is linked to other health conditions such as depression and heart disease as claimed by people on social media. She adds heart diseases, strokes, and other gastrointestinal conditions are rooted in inflammation and the vagus nerve is well understood to reduce inflammation. Still, more research is needed. Conway said electrical stimulation of the vagus nerve has been effective in reducing seizures in refractory epilepsy, as well as reducing depressive symptoms in patients with refractory depressive disorders. He adds stimulation of the vagus nerve may be helpful in obesity and chronic inflammatory diseases, too. • Breit S, Kupferberg A, Rogler G, Hasler G.
