Many people associate relaxation with the vagus nerve, but several cranial nerves play a meaningful role in calming the system. These cranial nerves travel through the head, neck and face, and while they are internal, some can be influenced externally through targeted touch. One of the most accessible is the trigeminal nerve, a major sensory nerve that can be stimulated through gentle pressure on the forehead.
Why the Trigeminal Nerve Matters
The trigeminal nerve has three main branches that carry sensory information from the face to the brainstem. The branch located at the centre of the forehead is of particular interest in yoga therapy. When stimulated, it sends signals to the nucleus tractus solitarius (NTS), the same brainstem region that receives input from the vagus nerve and helps regulate autonomic balance.
Unlike the vagus nerve, which cannot be stimulated directly by hand, the trigeminal nerve can be accessed externally. This offers a simple, practical entry point into down-regulating the nervous system without complex techniques or equipment.
How Forehead Pressure Supports Relaxation
Gentle pressure on the centre of the forehead may:
• stimulate the trigeminal nerve’s sensory fibres
• activate pathways shared with the vagus via the NTS
• promote autonomic regulation
• support a sense of grounding and internal quiet
This is one reason facial touch practices, guided self-massage or mindful contact at the brow centre can be soothing. In yoga therapy, these techniques are sometimes used alongside breathwork or grounding postures to deepen the relaxation response.

If you are interested in understanding how cranial nerves, interoception and autonomic regulation fit into therapeutic yoga, you can train directly with Heather Mason through our Minded Yoga Therapy Diploma, which explores these mechanisms in depth.
For those wanting shorter structured learning, Yoga Therapy Skills for Depression and Anxiety includes breathwork, grounding and body-based regulation strategies that complement trigeminal nerve work.
