When Mahesh Jayaraman, co-founder of Sepalika and Acupressure Therapist, studied a 2000-year old acupressure technique called Varmam in South India nearly a decade ago, his teacher would extol the virtues of washing one’s face with cold water first thing in the morning. It seemed intuitively right to Mahesh then, because it made him feel fresh and ready to take on a new day. Little did he know that the science behind this was far more astounding. Years later, when Mahesh was studying about a rather interesting nerve in the human body, called the Vagus nerve, he came to understand that washing your face with cold water was a way of directly stimulating this nerve. It is the single most important nerve in the parasympathetic nervous system, which helps us calm down and relax. He could clearly see why cultures across the world used it, especially as a way of relaxing a person’s mind before they entered a temple or place of worship.
The word Vagus means “wanderer,” because it wanders all over the body to various important organs. It begins near the anus and connects to the gut, the reproductive organs, kidneys, ureter, liver, gallbladder, stomach, pancreas, lungs, spleen, heart, entire neck area, the face, tongue, ears and finally enters the brain.
It powers up our involuntary nerve center—the parasympathetic nervous system—and controls unconscious body functions, as well as everything from keeping our heart rate constant and food digestion to breathing and sweating. It also helps regulate blood pressure and blood glucose balance, promotes general kidney function, helps release bile and testosterone, stimulates the secretion of saliva, assists in controlling taste and releasing tears, and plays a major role in fertility issues and orgasms in women.
The Vagus nerve has fibres that innervate virtually all of our internal organs. The management and processing of emotions happens via the vagal nerve between the heart, brain and gut, which is why we have a strong gut reaction to intense mental and emotional states.
There are anywhere up to 30-40 ways to stimulate the Vagus nerve, but for now, let’s look the top 10 ways to stimulate this nerve to receive multiple health benefits – both on chronic diseases you may already have and on overall health and prevention.
