Marcel Gerber was sent by a United Nations committee to study the effects of protein deficiency on Ugandan children. She found, to her surprise, that Uganda's infants were developmentally the most advanced in the world. It was only after two years of age that the children began to be seriously damaged by such things as tribal taboos and food shortages. Ugandan infants were almost constantly held by their mothers and mother surrogates. They went everywhere with their mothers. The physical contact with the mother and the constant movement seemed to be the factors that propelled these infants to maturity beyond Western standards.
Many young parents today understand this principle and make it a practice to massage their infants. That's a wise practice. We all have a need to be touched. Studies have shown that touching has physiological benefits even for adults. One researcher made numerous studies on the effects of the practice many Christians recognize called "laying on of hands." She discovered that when one person lays hands on another, the hemoglobin levels in the bloodstreams of both people go up, which means that body tissues receive more oxygen, producing more energy and even regenerative power.
