There are two types of Paida in terms of its intensity, i.e. gentle and heavy Paida. They are relative concepts. The same intensity may be “gentle” to one person, but “heavy” to another. The actual intensity varies with age, health condition, pain tolerance, the part of the body being slapped, environmental and other factors.
Technically speaking, slapping with wrist movement is gentle Paida; slapping with elbow joint movement is moderate Paida; slapping with shoulder joint movement is heavy Paida. Gentle, moderate and heavy Paida should be used alternately. The general rule is to go gradually from gentle to heavy Paida, and never start with heavy Paida. Adjust the intensity to the recipient’s pain tolerance. In the beginning, the painful sensation can be quite intense, but after a while, there will be less pain. At this point, the intensity may be increased gradually. The greater the intensity, the more pain will be felt; but as long as the pain is within a tolerable range, the effect of Paida will be better. However, it is the recipient who has the final say on how much pain he/she can take. The person doing Paida cannot force heavy Paida on the recipient. Gentle Paida can be as good as, or even better than heavy Paida, but will require a longer time. When a part of the body is slapped for up to one hour, the healing effect will be better.
