The Mind, Body & the Vagus Nerve Connection and the Visum Light

LED Light Therapy and the Vagus Nerve

As the most intricate of the cranial nerves, the vagus nerve (aka, the 10th cranial nerve) plays a critical role in the parasympathetic branch of the autonomic nervous system. Running from the brain to the abdomen, it helps control heart, lung and digestive tract function.

Due to its vital governance of such fundamental involuntary functions, low vagal tone (decreased vagus nerve activity) can have a wide range of detrimental effects on everything from your heart rate and blood pressure to your digestive system and emotional state.

Causes of Low Vagal Tone

Given the vagus nerve’s wide variety of functions, it’s no wonder that low vagal tone can be caused by a wide variety of issues. Those who have experienced early childhood trauma or head injuries, for instance. However, it can also be affected by lifestyle choices and even health issues beyond your control. Many adults live a lifestyle of chronic stress and poor sleep, making them prime candidates. And health issues such as chronic infections, poor breathing mechanics and imbalances in blood sugar are also prime causes.

  • Childhood trauma
  • Head injuries
  • Chronic stress
  • Poor sleep
  • Chronic infections
  • Poor breathing
  • Blood sugar imbalances 


Symptoms of Low Vagal Tone

The above issues and more can lead to low vagal tone, which manifests in a number of ways, both physically and mentally. From abdominal pain and poor gut function to anxiety and depression, low vagal tone has even been linked to autoimmune diseases, neurodegeneration and certain types of cancer.

  • Poor gut function
  • Chronic inflammation
  • Neurodegeneration
  • Poor emotional regulation
  • Lowered attention span
  • Depression & anxiety


LED Light Therapy & the Vagus Nerve

The vagus nerve affects bodily systems from the brain to the microbiome of the gut, and recent studies on the effects of photobiomodulation — PBMT, also known as light therapy — in these areas have produced some truly remarkable results, leading to additional continuing research and clinical trials to broaden our understanding of light therapy’s potential applications for an ever-growing myriad of diseases, disorders and conditions.

From Alzheimer’s, traumatic brain injury and ischemic stroke to depression and other mood disorders, PBMT has been found to reduce inflammation, promote cell energy generation and even increase connectivity between neural nodes in human chronic TBI patients(Hamblin, 2016). 

The body’s microbiome affects autoimmunity, metabolism, obesity and more, with one report (Liebert et al., 2019) noting that “the gut microbiome (whether healthy or not) has a profound effect on …. direct vagal nerve stimulation.” Research exploring light therapy’s applications in this realm continues to garner attention, so much so that the term “photobiomics” has been introduced to highlight this area of study’s vast promise.

With successful research on the microbiomes of mice and many human trials currently investigating autoimmune disorders, metabolic disorders and much more, it’s likely we’ll soon receive further evidence supporting Ann Liebert, et al. and their assertion that “recent preliminary work from our laboratory (unpublished) has also indicated that changes in the human (quasimetabolic syndrome) microbiome occur after treatment with PBM … all recognized as correlated with a healthy microbiome.”

The Visum Light & The Vagus Nerve

Periodic two-minute, continuous-beam exposures to the Visum Light’s turquoise color combination at the base of the neck helps stimulate the vagus nerve and improve vagal tone — painlessly, noninvasively and with virtually no side effects.

Shown to relieve cranial pressure while easing mental and emotional stress, the combination of blue and green light engages the parasympathetic nervous system to help ease the causes and symptoms of low vagal tone. Continued sessions can help lead to improved moods, more tranquil outlook and improved sleep. Stimulating the vagus nerve also benefits the microbiome of the gut, helping improve digestive function and easing symptoms associated with digestive disorders.

The Visum Light’s secret is in providing the user with the ability to mix color combinations, set Nogier frequencies, and adjust duration and other settings. Combined with its convenient automatic settings and easy-to-use interface, it’s the Visum Light’s versatility that makes it the most advanced, sought-after LED light therapy device on the market today.

As the world of light therapy evolves, the Visum Light allows you to evolve right along with it, making it the only light therapy device you’ll ever need.

With our 45-day No Worries Guarantee, medical professionals and at-home users alike can try the Visum Light at no risk.
