The Effects of Vagus Nerve Stimulation on Insomnia Persons for Stress Reduction and Sleep Induction

In recent years, the stress level increases and sleep quality decreases in the day-to-day life among the people. Vagus Nerve Stimulation (VNS) plays a vital role in stress reduction. This study aims to assess the stress reduction and the sleep induction effects on insomnia persons using non-invasive wearable AMO+ VNS device. The physiological signals such as Electrocardiogram (ECG) and Electroencephalogram (EEG) are measured during resting condition before and after the use of fake and the real device, respectively. The statistical t-test is performed. After the use of real AMO+ device the HF ratio increases significantly, although no significant changes in HR, α power ratio increases in the prefrontal (Fp1, Fp2) and frontal (F3, F4) areas of the brain. The significant increase in the melatonin level is noticed during 10.00 pm to 12 midnight after the use of the real AMO+ device.
