Have you ever wondered how it is that positive and negative experiences in early childhood can affect our health and well-being as adults?
In the early years of life a child’s brain is being sculpted by the experiences it receives. Experiences act on genes like a dimmer switch to increase or decrease the amount of protein that a gene makes in response to a given environment. These interactions between genes and environment is what we call epigenetics.
In short, the way experience gets embedded in our biology is what explains individual differences in children’s development and health.
