A new study says that the amount of comforting contact a young infant gets can actually affect the epigenome—the biochemical changes that influence gene expression in the body. These changes in gene expression can work to boost the genes that back the immune system as well as the metabolic system. Although the research is still in its early days, these findings could give scientists some useful insights into how touching affects an infant’s development.
