Main nerves belonging to the parasympathetic nervous system are vagus nerves or vagal nerves. Our immune system plus digestion and heart rate etc are controlled by this important vagus nerve in us

Location of vagus nerve:
It is worth mentioning that the vagus nerve would run from the brain through the face and thorax to the abdomen in us.  When there is a lack of nutrients in the vagus nerve, then we could get issues in sleeping, lowered immunity levels and reduced mental clarity etc. It is believed that by supporting the vagus nerve with nutrients then the messages sent would be strong and clear. Truth is that the brain would be able to hear and respond to the requirements of the body.

To support our vagus nerve, we must eat the following nutrients without fail.

Choline intake:
It is brought out that the intake of choline (that is present in red meat and fish etc) which is an important neurotransmitter has a protective effect on our arteries.

Vitamin B12 intake:
The intake of vitamin B12 would metabolise fatty acids as well as amino acids. It is known to us that vitamin B12 is found in eggs and dairy products etc.

Magnesium intake:
When we consume magnesium, then there would be the regulation of muscle contraction, BP and insulin metabolism etc. Magnesium is found in abundance in green leafy vegetables etc.

Sodium intake:
It must be noted that the intake of sodium would help in the muscle contraction, neuronal activity and nutrient absorption etc. We could consume sodium as salt.

Omega 3 fatty acids intake:
It is noteworthy that omega 3 fatty acid is present in flax seeds, chia seeds, walnuts etc. Point is that omega 3 fatty acids would help in the production of hormones and regulation of heart rate etc.

Activating vagus nerve for better sleep:
These days many people have trouble in sleeping. Either we get delayed sleep or get up in the middle of the night and are not able to sleep again. According to some health experts, by stimulating the vagus nerve the parasympathetic nervous system would get activated. This could lead to sound sleep.
