Turtles pull their heads in to their bodies when they are scared. Do you do the same thing? Notice the triggers, and then invite a sense of ease in your neck, so your head can can lengthen away from your body.
If you are finding this hard, look around you and make sure that you are safe. Are you near loud rumbling low pitched noises? Try and get somewhere quiet, or even turn on some melodic vocal music – or sing. If you can have a friendly face-to-face conversation that might be the best thing, but if there’s no one around, take a minute to look at pictures of baby animals. All of this will help cue your nervous system towards a sense of safety. Feeling safe facilitates a release in the neck and throat muscles, allowing the head to easily extend away from the body.
