Toxic Stress Derails Healthy Development

Not all stress is bad. But toxic stress—excessive or prolonged activation of stress response systems in the brain and body—can impact early childhood development. Activation of our stress response systems produces a wide range of physiological reactions, including increased heart rate, elevated blood pressure, and the release of stress hormones like cortisol. When a young child has supportive caregiver relationships, these responses are brief and return to normal quickly. However, when these responses remain activated at high levels for extended periods of time—without supportive relationships to help calm them—toxic stress can result. Toxic stress can disrupt the healthy development of brain architecture and the development of biological systems more broadly, with impacts on learning, health, and well-being across the lifespan. Reducing children’s exposure to toxic stress and providing safe, stable developmental environments can prevent or reverse the damaging effects of toxic stress.
