As a society, we are touch deprived and this can lead to disease or emotional dysfunction. From the cradle to the nursing home, tactile stimulation and the emotional assurance of caring touch bring about a sense of well-being and security. In numerous studies conducted on massage for infants, TRI researchers have found improved weight gain and development in pre-term infants, improved weight gain and motor behavior in cocaine-exposed infants, and improved weight gain and decreased stress behavior in HIV-exposed infants. Full-term infants also benefit with increased alertness and social behavior, less crying and increased weight gain.
