Understanding Vagus Nerve Stimulation and Its Benefits

Vagus nerve stimulation (VNS) involves using devices to send electrical pulses to the vagus nerve, which can be done invasively or through skin patches, and is used for conditions like epilepsy and cluster headaches. While some users report benefits such as increased energy and improved sleep, scientific evidence is limited, and the effectiveness of these devices remains uncertain, with some experts suggesting placebo effects may play a role.
