Biothm's black ear clip electrode wire for vagus nerve and CES stimulation using TENS 7000 unit. Boosts "rest and digest" parasympathetic activity and reduces "fight or flight" sympathetic activity in adults. Quality of life, mood and sleep changes may be improved with transcutaneous vagus nerve stimulation administered for 15 minutes every day for two weeks. Improvements in depression, anger, tension, confusion and low energy. Conditions like leaky gut, gut dysbiosis, fibromyalgia, chronic fatigue syndrome, heart disease Alzheimer’s disease and chronic fatigue syndrome are associated with low activity of the vagus nerve. Vagus nerve stimulation helps prevent and lessen the recovery time from seizures by sending, mild electrical pulses to the brain via the vagus nerve.
