The hand reflex zones correspond to the foot reflex zones, the massage treatment of which is generally known today. Both of the following illustrations show the reflex points or surfaces that are connected with the muscles and organs. Since some of the organs are only found on one side of the body (such as the heart and liver), this is reflected in the hands.
Since hands come in different sizes, you may not find the exact pressure point immediately. But with some practice, even the nonexpert can find the right spot.
When you have found the desired point, massage it with your thumb, using light pressure and slow, circular movements. One to 3 minutes are enough.
