Cuidar do nervo vago para reduzir a ansiedade e melhorar a qualidade de vida

O nervo vago inerva grande parte do nosso organismo. De tal forma que muitos o definem como uma força motriz, um canal interno que regula o descanso e que, além disso, desativa as respostas ansiosas do nosso corpo. Saber estimulá-lo através de exercícios como a respiração diafragmática nos ajudaria sem dúvidas a reduzir muitas dessas emoções negativas que nos atormentam todos os dias.

Vamos pensar por um momento em todas essas situações que geram ansiedade, em tudo aquilo que produz medo, incômodo, repulsa… Vamos visualizar esses momentos vitais e perceber como em um dado momento nosso estômago ou nosso intestino começa a ter espasmos, cólicas, a se agitar com muitas borboletas bravas no seu interior. Essa sensação ativa imediatamente o nervo vago e envia ao cérebro uma mensagem categórica: “temos uma ameaça”.

Vagus Nerve Stimulation Dramatically Reduces Inflammation

Vagus Nerve Stimulation Dramatically Reduces Inflammation

Inflammatory responses play a central role in the development and persistence of many diseases and can lead to debilitating chronic pain. In many cases, inflammation is your body’s response to stress. Therefore, reducing “fight-or-flight” responses in the nervous system and lowering biological markers for stress can also reduce inflammation.

Typically, doctors prescribe medications to combat inflammation. However, there’s growing evidence that another way to combat inflammation is by engaging the vagus nerve and improving “vagal tone.” This can be achieved through daily habits such as yoga and meditation—or in more extreme cases of inflammation, such as rheumatoid arthritis (RA)—by using an implanted device for vagus nerve stimulation (VNS).

The vagus nerve is known as the “wandering nerve” because it has multiple branches that diverge from two thick stems rooted in the cerebellum and brainstem that wander to the lowest viscera of your abdomen touching your heart and most major organs along the way. Vagus means “wandering” in Latin. The words vagabond, vague, and vagrant are all derived from the same Latin root.

In 1921, a German physiologist named Otto Loewi discovered that stimulating the vagus nerve caused a reduction in heart rate by triggering the release of a substance he coined Vagusstoff (German for “Vagus Substance”). The “vagus substance” was later identified as acetylcholine and became the first neurotransmitter ever identified by scientists.

Vagusstoff (acetylcholine) is like a tranquilizer that you can self-administer simply by taking a few deep breaths with long exhales. Consciously tapping into the power of your vagus nerve can create a state of inner-calm while taming your inflammation reflex.

The vagus nerve is the prime component of the parasympathetic nervous system which regulates the “rest-and-digest” or “tend-and-befriend” responses. On the flip side, to maintain homeostasis, the sympathetic nervous system drives the “fight-or-flight” response.
