Everyone gets stressed, but some people can relax quickly. That ability to pivot from the "fight-or-flight" response to the "rest-and-digest" response, it turns out, is incredibly important for health.
So what am I talking about?
It's called "vagal tone" because it's the vagus nerve, which runs from the brain through the lungs and the gut, that controls these responses. A high vagal tone is linked with reduced risk for cardiovascular disease, stroke, diabetes, gastrointestinal disorders and depression.
The vagus nerve helps to regulate your heart rate, breathing, blood pressure, digestion, and emotional state among other functions. If you are experiencing anxiety, depression, stress, fatigue, or any emotional health symptoms, it may mean that you have a poor vagal tone, and your vagus nerve needs some care.
Your vagus nerve, also known as the 10th cranial nerve, is one of your most important nerves in the body. It is also the longest nerve in your autonomic nervous system that extends from your brain stem through your neck into your chest and abdomen. While we refer to them together as "the vagus nerve," there are actually two vagus nerves, one on the left and one on the right. Vagus is latin for "wandering" which appropriately describes the nerve.
It helps to regulate your heart rate, digestion, blood pressure, sweating, and speech, among other areas of your health. By controlling the muscles of your throat and voice box, it plays an important role of speaking and eating. It also helps your entire gastrointestinal tract working together, regulating your heart rate, and connecting your brain to the rest of your body.
THE POLYVAGAL THEORY
While grazing, the gazelle felt safe and connected, when it was caught, the body went through a shutdown, but when the opportunity arose, flight-or-fight kicked in and it ran away. This story covers the exact same three states that the polyvagal theory focuses on connection, fight or flight, or shutdown.
Before the emergence of the polyvagal theory, we only understood the nervous system as a two-part system with more activation and less calm or less activation and calmer. The polyvagal theory identified the social engagement system as a third type of nervous system response.
So the moral of this short story is that if you are emotionally healthy in a non-stressful situation, you are in a normal state the polyvagal theory refers to as connection. In this state, you are able to make healthy connections with humans and feel safe. At this point, you feel happiness, peace, openness, calm, groundedness, and curiosity. You sleep well. You eat normally without overeating or undereating. Your immune system is functioning well. Your face is expressive, your body is calm, and you are able to relate to others emotionally.
FIGHT OR FLIGHT VS REST & DIGEST/HEAL
When you are under stress, it affects your entire body. Your sympathetic nervous system causes a flight-or-fight response to keep you alive. Even if you are not in real danger, but only experiencing daily stress, your body wants to keep you safe.
Experiencing a flight-or-fight or shutdown response to something scary, stressful, or triggering is absolutely healthy. We all do it. If there is a flash of lightning, or your boss calls you into their office unexpectedly, or someone suddenly cuts you off on the highway, you may experience signs of flight-of-fight, including increased heart rate, heavier breathing, or a need to scream.
THE IMPORTANCE OF GOOD VAGAL TONE
The vagal nerve is involved in many areas across your body making a good vagal tone very important. A good vagal tone is important for:

If you work at a desk job, here is your guide to staying healthy during the day.
Your body was designed for full range of motion, and simply standing does not optimize your physiology either. The key is movement, not simply standing statically. Sitting can also be healthy when done correctly. It is key to always maintain good posture. So try to keep your back straight, your feet on the ground, keyboard close to you, and monitor at eye level. Research from Dr. James Levine shows that for every hour we sit down, our life expectancy decreases by about two hours. For comparison, every cigarette smoked reduces life expectancy by 11 minutes. That means sitting down can be far more hazardous to our health than smoking, which is a shocking revelation for most. But, and this is very interesting, we cannot simply replace sitting with standing. Our body was designed for full range of motion, and simply standing does not optimize our physiology either.
In addition to staying active, it is also very beneficial for your health to stretch. Especially those tight hip flexors, the lower and upper back, and shoulder complex. Find simple stretching exercises that can alleviate pain. Laying over a Swiss ball for a few minutes can assist in stretching that lower back and open up the shoulder blades.
