It is the longest cranial nerve, starting from the brain and descending through the neck to the abdomen. Its main role is to transmit information between the brain and many important organs in our body, including the heart, lungs and digestive tract.
The vagus nerve is involved in a variety of functions, including controlling heart rate, regulating breathing, secreting digestive juices, and influencing mood and emotional reactions. It is also involved in regulating inflammation and the body’s immune response.
In addition to these physical functions, the vagus nerve also plays a role in brain-body communication regarding mental well-being. It is involved in regulating stress and anxiety levels, contributing to relaxation and calming reactions.
More recent studies have begun to explore the connection between the vagus nerve and mental health, including the possibility of using vagus nerve stimulation to treat depression and other mental disorders.
Factors that can stimulate the vagus nerve
Deep breathing
A study shows that the effects of slow yogic breathing, which can be performed at different rates of inhalation and exhalation, increased the sensitivity of baroreceptors and vagal activation, which means a decrease in blood pressure.
Your heart and throat contain neurons that have receptors called ‘baroreceptors’.
Deep, slow breathing is believed to stimulate the vagus nerve and is useful in certain types of meditation, yoga, and relaxation techniques.
Meditation
Practicing meditation can have a calming effect and stimulate the vagus nerve.
Studies suggest that at least three types of meditation can indirectly stimulate the vagus nerve. A conscious and deep breathing that accompanies the meditation stimulates the vagal nerve and the nervous activity of rest and digestion.
MASSAGE
Massaging certain areas, such as the carotid sinus (located on the neck), pressure massage, and massaging the soles of the feet, can also increase vagus nerve activity and lower heart rate and blood pressure.
Positive thoughts
Positive thoughts can influence the activity of the vagus nerve through the nervous system. Studies show that positive thinking and gratitude practices can reduce stress and anxiety and improve mood, and this may be linked to activation of the vagus nerve.
The cold
Exposure to cold can be a stimulus to the nervous system and the vagal nerve. Cold can trigger a body response that includes stimulation of the vagal nerve to regulate body temperature and maintain homeostasis.
Several studies suggest that exposure to cold temperatures can activate the vagal response, which can have calming and anti-inflammatory effects in the body. This can help reduce stress and anxiety and promote a general sense of well-being.
Laugh
Intense laughter can activate the vagal nerve, which is part of the nervous system and is responsible for regulating involuntary body functions such as heart rate, digestion and breathing. It can reduce levels of stress hormones such as cortisol and promote the release of endorphins, leading to a state of relaxation and well-being.
Probiotics
Probiotics can help maintain a healthy balance of gut bacteria and reduce inflammation in the gut. This can have a positive effect on the health of the vagus nerve, as chronic inflammation can negatively affect the activity of the vagus nerve.
Consuming probiotics can improve the balance of beneficial bacteria in the gut, which can have a positive impact on vagal nerve function. A healthy gut flora can help regulate the nervous system and reduce the risk of stress- and anxiety-related conditions.
The intermediate post
Intermittent fasting can reduce inflammation in the body, including the gut, which can have a positive effect on the health of the vagus nerve. Chronic inflammation can negatively affect the function of the vagal nerve, and reducing it can improve communication between the gut and the brain.
Some studies suggest that intermittent fasting can stimulate neural regeneration processes, including in brain regions associated with the autonomic nervous system, such as the vagus nerve.
gargle
Gargling can influence the activity of the vagal nerve, especially in the context of using certain substances or solutions that can have effects on receptors in the throat and oral cavity.
Some people use solutions of essential oils diluted in water to gargle. Certain essential oils, such as peppermint or eucalyptus oil, can have invigorating and airway-opening effects, and their aromatic odors can influence the activity of the vagal nerve through the olfactory receptors.
Acupuncture
In acupuncture, there are specific points on meridian pathways that are associated with various body functions. Some of these points may be related to the vagus nerve or nervous system. Stimulating these points can activate the vagus nerve and promote relaxation and balance.
However, it is important to emphasize that the connection between the vagus nerve and the endocrine system is complex and is still the subject of further research to fully understand how these processes interact.
