The Power of the Vagus Nerve and Cold Water for Mood and Stress Relief
The vagus nerve, which is linked to gut and heart health as well as mood, can be stimulated to improve vagal tone and overall well-being. While invasive methods like implantable vagus nerve stimulators exist, there are also non-invasive approaches such as nutrition, exercise, and psychological stress management. Cold water exposure has been found to increase parasympathetic tone and heart rate variability, leading to better vagal activity. However, it's important to consult a physician before trying any new habits that may affect the vagus nerve.
