Chi or Qi vitality streams in the body through pathways, other known as meridians. It is the base of the Traditional Chinese Medicine.
That is the reason it’s trusted that with needle therapy the blockage of the Chi vitality is discharged. In that way the vitality streams better through the body and the capacity of the body organs is made strides. Generally that blockage will prompt disease.
Each meridian contains pressure points. With stimulation of them by acupuncture, or acupressure, the Qi energy is released and the tension in the body is reduced.
Similarly to this, it is believed that by putting an ice on the neck (on a specific spot) you can improve you mood, overall health, while feeling energized at the same time.
This specific spot on the neck is known as Feng Fu Point.
In Traditional Chinese medicine it is believed that ice can energize the body and provide physiological balance.
