The human body has 7 trillion nerves, and a large portion of those nerves end as highly specialized cells at the level of the skin. These specialized nerve endings are pain, temperature, and pressure sensitive. Those specialized cells are gathering information about your surroundings 24/7. If your body has a misalignment that is causing nerve pressure called Subluxation it will create a type of sensory noise that will not allow you to turn off or be at rest. This can result in trouble getting comfortable, falling asleep, and staying asleep through the night.
