Anxiety disorders affect a significant portion of the population, leading to a growing interest in new treatment approaches. In a study on the Roga tVNS device, researchers found that daily use of auricular transcutaneous vagus nerve stimulation (tVNS) over four weeks significantly reduced anxiety in participants with moderate to severe anxiety. The active treatment group experienced a 47% decrease in GAD-7 scores and a 14% decrease in STAI-S scores, demonstrating that tVNS is a promising and effective non-invasive treatment for long-term stress relief.

The vagus nerve is vital for regulating stress and recovery, with its function measured by heart rate variability (HRV). This study showed that a single 1 hour tVNS session significantly enhanced vagal activity. The stimulation increased HRV's high frequency (HF) power by 48%, while other markers like RMSSD and the LF/HF ratio also indicated a strong shift toward parasympathetic dominance. The study confirms that tVNS can effectively increase HRV and improves autonomic balance.

Brainwave activity studies are crucial for understanding how non-invasive techniques like auricular transcutaneous vagus nerve stimulation (tVNS) can help patients regulate their stress levels. This study found that the stimulation can significantly increase alpha brainwave activity, a state linked to relaxed mental processing. The stimulation also boosted neural responses for attention and emotional control, which suggests it may help to downregulate stress related brain networks and rumination.

In today's fast-paced world, stress, burnout, and anxiety are a widespread concern affecting millions. This study used non-invasive vagus nerve stimulation (nVNS) to attempt to alleviate some of the anxiety symptoms. The results were primarily measured using the Generalized Anxiety Disorder 7-item (GAD-7) scale, a widely used clinical tool to assess the severity of anxiety symptoms. Participants with moderate to severe anxiety saw a 54% reduction in their GAD-7 scores within just two weeks, moving from the severe to the mild range.
