The most important part in a human body is the nervous system. It comprises of various nerves that transmit signals to different parts of the and controls their actions and movement. Basically, it resembles an electrical wiring connection that keeps the human machine in active state. So, to maintain good health, both physically and mentally, we have to focus on the nervous system.
An inefficient nervous system leads to problems like migraine and depression. How to combat them?
Stimulating a particular nerve, called the Vague Nerve, effectively helps us face migraine and depression.
The vague nerve is the longest nerve in the body. It originates in the brain from the cranium as the cranial nerve and then travels down through the backside of the neck and then passes the heart, lungs, digestive system, liver, spleen and pancreas.
The Vague nerve plays an important role in the parasympathetic nervous system. It forms part of involuntary nervous system and keeps the heart rate constant and controls digestion. VNS is vagus nerve stimulation and it is used to treat people with epilepsy and depression.
Vagal tone plays the key role in activating the parasympathetic nervous system. It is measured by tracking the heart rate along with the breath rate. Our heartbeat rate increases during inhaling and decreases when we exhale. The higher the difference between the heartbeat rate while inhaling and exhaling, the higher is the vagal tone.
High vagal tone suggests that the body can relax faster after a stressful situation. This improves the functioning of many other body systems and leads to regulation of blood sugar levels, reduced risk of stroke and cardiovascular diseases, lower blood pressure, improved digestion and reduced incidence of migraine. In simple words, it means better mood, less anxiety and more stress resilience.
Low vagal tone can be associated with cardiovascular conditions and strokes, depression, diabetes, chronic fatigue syndrome and cognitive impairment. It may also result in higher rates of inflammatory conditions, including autoimmune diseases such as rheumatoid arthritis and inflammatory bowel disease.
