The gut-brain connection is crucial to health and wellness, with stress significantly influencing our gut microbiome and immune system.
Recent research by the Nash Family Department of Neuroscience, Icahn School of Medicine at Mount Sinai, New York, has found stress can suppress the central amygdala in the brain, leading to adverse effects on the Brunner glands and mucus production in the gut. This decreases beneficial bacteria and increases susceptibility to infections. This direct impact on our immune support system makes exploring strategies to mitigate its effects essential.
Stimulating the Vagus nerve, a vital component of the parasympathetic nervous system can positively impact stress reduction and immune support. Modulating the Vagus nerve's activity can counteract the detrimental effects of stress on the gut-brain axis, promoting a healthier gut microbiome and bolstering the immune response.
Minimising exposure to unnecessary stressors, such as negative news and social media reporting, can be beneficial for maintaining a healthy gut microbiome and immune system. Additionally, exploring interventions targeting vagus nerve stimulation may offer promising avenues for enhancing stress resilience and immune support.
Holistic approaches that encompass mental and physical well-being are essential to nurture a resilient and thriving mind-body connection. Recognising the profound impact of stress on our health and understanding the potential of Vagus nerve stimulation can boost immune support and help us maintain overall well-being and resilience.
Methods of stimulating the vagus nerve include:
- Exposure to cold, e.g. cold water on the face
- Massage
- Oral Stimulating - Humming/singing
- Probiotics, live (not in tablets)
- Sleeping on your right side
In summary, activation of either the central amygdala or vagal parasympathetic nervous system is sufficient to completely reverse the effects of stress on the microbiome and immunity.
