3. Toxic Stress Derails Healthy Development

Learning to deal with stress is an
important part of healthy development. When experiencing stress, the stress
response system is activated. The body and brain go on alert. There’s an adrenaline rush, increased heart
rate, and increase in stress hormone levels. When the stress is relieved after a short time or a
young child receives support from caring adults the stress response winds down and the
body quickly returns to normal. In severe situations, such as ongoing abuse and neglect, where
there is no caring adult to act as a buffer against the stress,
the stress response stays activated. Even when there is no apparent physical harm, the extended absence
of response from adults can activate the stress response system. Constant activation of the stress response overloads developing
systems with serious, lifelong consequences for the child. This is known as toxic stress. Over time, this results in the stress response
system set permanently on high alert. In the areas of the brain dedicated to learning and reasoning,
the neural connections that comprise brain architecture are
weaker and fewer in number. Science shows that the prolonged activation of stress
hormones in early childhood can actually reduce neural connections
in these important areas of the brain at just the time when they should be
growing new ones. Toxic stress can be avoided if we ensure that
the environments in which children grow and develop are nurturing, stable, and engaging.
