Chronic anxiety is a statemarked by sustained activation of the masseter muscle, manifesting in both mental and physical strain. This prolonged tension can significantly impact wellbeing cognitive abilities, posing risk for range health complications. double-blind, randomized, controlled clinical trial investigated transcutaneous auricular vagus nerve stimulation (TAVNS) on muscle activity, pressure pain threshold (PPT), levels university students with elevated anxiety.
