The origins of acupressure are as ancient as the instinctive impulse to hold your forehead or temples when you have a headache. Everyone at one time or another has used his/her hands to hold tense or painful places on the body.
More than 5,000 years ago, the Chinese discovered that by pressing certain points on the body, the pain in that pressure point could be relieved. They also found this application of pressure to benefit other parts of the body further away from the pain point.
Gradually, they identified several pressure points that not only alleviated pain but also influenced the functioning of certain internal organs.
