What are suboccipital muscles? How do I find them with this product?

The suboccipitals are four paired muscles at the top of your neck and just beneath the skull. These muscles help stabilize and move your head. When they become irritated or tight, they can cause neck stiffness and headaches.

To find these muscles, feel for the bony protrusion at the center of the back of your head, close to where it meets the neck. Just below and to each side of that protrusion are your suboccipital muscles. You can also locate them by feeling the same area with your fingers, then gently nodding your head, like you're saying "yes." Adjust the nodes of the Contrast™ to land directly on these muscles when you lie down on it.

How can I adjust the pressure on the ThermaTouch™ nodes?

The shape of the ThermaTouch™ nodes is designed for either direct pressure or gentle, spread-out pressure. If you prefer more direct pressure, orient the Contrast™ so that the 'fingers' on the nodes are pointing up. If you prefer a more gentle pressure, orient the Contrast™ so that the 'fingers' on the nodes are pointing down.
 


How do I use this product?

1. Turn on the Contrast™ and select the desired mode.
2. Find a flat surface and lie down.
3. Orient the Contrast™ to your preferred pressure and gently lay your head back onto the nodes.
4. Slide the nodes in or out until they are directly under your suboccipital muscles.
5. Relax your head, neck, and body.
