Your vagal nerves make up 75% of your parasympathetic nervous system. This is the part of your body that controls involuntary functions such as heart rate, immune system regulation, digestion, fight or flight response, etc. But did you know that the vagal nerve can also affect mental health? Low activity of the vagal nerve is referred to as low vagal tone. This has been associated with difficulty in coping with stress, an increased risk of depression, and even reduced cognitive functioning. The good news is that there are steps people can take to naturally increase vagal tone. Among them are deep breathing, meditation/mindfulness, regular physical activity, brief exposure to cold, and connecting socially. Read more about the vagal tone in this interesting article.
