What happens in your brain when you get a massage?

Updated

Thalamus relays touch to somatosensory cortex, which maps the pressure. The insula integrates bodily feelings, while the anterior cingulate processes emotional calm and modulates pain. The hypothalamus then shifts the body into relaxation mode.

Thalamus, Somatosensory Cortex, Insula, Anterior Cingulate Cortex, Hypothalamus lit up on the Brain Atlas 3D brain: what happens in your brain when you get a massage
Figure. The brain regions that light up when you get a massage, in order: Thalamus (touch relay), then Somatosensory Cortex (mapping touch), then Insula (body awareness), then Anterior Cingulate Cortex (relaxation response), then Hypothalamus (parasympathetic shift).

Brain regions that light up

OrderRegionWhat it does here
1ThalamusThe thalamus receives touch signals from the spinal cord and sends them to the cortex.
2Somatosensory CortexThe somatosensory cortex processes where and how intense the massage touch is.
3InsulaThe insula integrates bodily sensations, creating a felt sense of the massage.
4Anterior Cingulate CortexThe anterior cingulate cortex processes the emotional and calming aspects of touch.
5HypothalamusThe hypothalamus triggers a relaxation response, slowing heart rate and lowering stress hormones.

1. Thalamus: touch relay

As the brain's sensory relay station, the thalamus filters and directs incoming tactile information. It ensures that touch, pressure, and temperature data reach the appropriate cortical areas for conscious perception.

2. Somatosensory Cortex: mapping touch

Located in the parietal lobe, this region contains a topographic map of the body. Neurons here respond to specific skin areas, allowing you to localize the massage strokes and discriminate pressure, vibration, and texture.

3. Insula: body awareness

Step 3 of what happens in your brain when you get a massage: Thalamus, Somatosensory Cortex, Insula lit on the Brain Atlas 3D brain

The insula is key for interoception—the perception of internal body states. It combines tactile input with emotional and autonomic signals, producing the subjective feeling of being touched and the accompanying sense of bodily comfort.

4. Anterior Cingulate Cortex: relaxation response

Step 4 of what happens in your brain when you get a massage: Thalamus, Somatosensory Cortex, Insula, Anterior Cingulate Cortex lit on the Brain Atlas 3D brain

This region is involved in pain modulation and emotional regulation. During a massage, increased activity here can help reduce perceived stress and pain, perhaps by dampening signals from threat-related areas like the amygdala.

5. Hypothalamus: parasympathetic shift

Step 5 of what happens in your brain when you get a massage: Thalamus, Somatosensory Cortex, Insula, Anterior Cingulate Cortex, Hypothalamus lit on the Brain Atlas 3D brain
Figure 5. Hypothalamus, parasympathetic shift: The hypothalamus triggers a relaxation response, slowing heart rate and lowering stress hormones.

As the master regulator of homeostasis, the hypothalamus coordinates the autonomic nervous system. Massage can shift the balance toward the parasympathetic branch, reducing cortisol levels and promoting a state of calm and restoration.

Good to know

  • C-tactile afferents are unmyelinated fibers that respond to slow, gentle stroking and are implicated in pleasant touch perception.
  • Massage is thought to reduce cortisol levels, though effect sizes vary across studies.
  • The insula integrates interoceptive signals and is active during both touch and emotional awareness.

Massage vs pain

Both massage and a painful pinch activate the thalamus and somatosensory cortex. However, massage engages the insula for interoceptive processing and the anterior cingulate for emotional calm, while pain triggers the amygdala and a sympathetic stress response. The hypothalamus shifts toward relaxation in massage but toward arousal in pain.

Test yourself

  1. Which brain region acts as the initial relay for touch signals during a massage?

  2. What role does the insula play in massage perception?

  3. How does the hypothalamus contribute to the relaxing effect of massage?

Simplified: many regions work together at once, and this shows the main players in the order they act.
