Definition of Stress

  • Source: World Health Organization (WHO)

  • Stress: A state of worry or mental tension caused by a difficult situation; a natural human response prompting action against challenges.

  • Everyone experiences stress; responses to stress impact overall well-being.

Types of Stress/Response

  • Source: Toxic Stress. Center on the Developing Child at Harvard University

  • Types of Stress Response:

    • Positive

    • Tolerable

    • Toxic

Positive Stress Response

  • Characteristics:

    • Brief, infrequent, mild to moderate intensity

    • Most normative response to stress

  • Examples:

    • A 2-year-old stumbling while running

    • Beginning school or childcare

  • Effects:

    • Social-emotional buffers help return to baseline

    • Builds motivation and resiliency

  • Note: Positive stress does not mean the absence of stress.

Tolerable Stress Response

  • Characteristics:

    • Exposure to significant but not everyday experiences.

  • Examples:

    • Death in the family

    • Natural disasters

  • Effects:

    • Buffers can provide protection and promote a return to baseline

    • A single negative event doesn't necessarily result in long-lasting issues.

Toxic Stress Response

  • Characteristics:

    • Long-lasting, chronic stress rather than a single event

    • Linked to adverse childhood experiences (ACEs) such as abuse and household dysfunction

  • Effects:

    • Insufficient social-emotional buffering

    • Potentially permanent changes and long-term effects

    • Impacts brain architecture and genetic expression (epigenetics).

Fight, Flight or Freeze

  • Discusses when stress becomes toxic.

Importance of Social-Emotional Cushion

  • The quality of social-emotional support distinguishes tolerable from toxic stress levels.

Consequences of Toxic Stress

  • Source: Harris, N. (2015) TED Talk on childhood trauma.

  • Childhood trauma leads to lifelong health consequences.

Types of Trauma

  • Acute Trauma: One-time events such as natural disasters or unexpected loss.

  • Chronic Trauma: Repeated experiences over time (e.g. domestic violence).

  • Complex Trauma: Exposure to multiple traumatic events, especially severe abuse in early years.

Examples of Trauma

  • Acute Trauma Examples:

    • Car accidents

    • Natural disasters

    • Physical or sexual abuse

    • Loss of significant others.

  • Chronic Trauma Examples:

    • Family instability

    • Poverty

    • Domestic violence

    • Bullying.

Stress Vulnerability Factors

  • Various intrinsic predispositions and life crises can increase vulnerability to stress impacts.

Complex Trauma in Childhood

  • Emerges from overlapping traumatic events and cumulative risk factors.

  • Symptoms can develop at any age.

Impact of Childhood Trauma

Relationships

  • Attachment issues, difficulty forming relationships, and a cycle of abuse.

Mental Health

  • Increased risks of depression, anxiety, low self-esteem, PTSD, and suicidal thoughts.

Physical Health

  • Sleep disorders, eating disorders, cardiovascular diseases, and shorter life spans.

Behavior

  • Increased sensitivity to stress, emotional control difficulties, shame, and helplessness.

Cognition

  • Language delays, problems solving issues, concentration difficulties, reduced learning ability.

Brain Development

  • Poor academic performance; long-term cognitive impacts.

Trauma and Brain Development

  • Experiences play a critical role in brain architecture development.

ACEs and Toxic Stress

  • ACEs: Adverse Childhood Experiences such as abuse, neglect, and household violence.

  • Correlation: Higher ACEs correlate with increased health and cognitive issues later in life.

Addressing and Preventing Toxic Stress

  • Importance of protective factors and resilience in mitigating stress effects.

Protective Factors for Resilience

  • Key factors promoting development include:

    • Safe environments and neighborhoods

    • Supportive social connections

    • Knowledge of parenting and child development

    • Access to medical and nutritional resources

    • Nurturing and attachment fostering

    • Inclusion and equity addressing.

Resilience Defined

  • Resilience is the ability to cope effectively with adversity, adjusting to both internal and external demands.

  • Responses to adversity foster healthy child development.

Importance of Supportive Relationships

  • Caring adult relationships during stress can buffer negative effects and promote recovery.

  • The more adverse childhood experiences, the greater risk of developmental delays and health problems.
