Understanding Stress in Childhood

Stress is often talked about as something to avoid, but the truth is more nuanced. Not all stress is harmful — in fact, some stress is essential for healthy development. What matters is the type of stress, how long it lasts, and whether a caring adult is present to help a child navigate it. Researchers categorize stress into three types: positive, tolerable, and toxic. Each affects the developing brain differently, and understanding these distinctions helps families and schools create environments where children can thrive.

Positive Stress:
The Good Kind That Builds Resilience

Positive stress is brief, mild, and supported by caring relationships. It’s the kind of stress children experience when:

• Meeting a new teacher
• Trying a challenging puzzle
• Performing in a school play
• Learning to ride a bike

These moments activate the body’s stress response just enough to build confidence, problem‑solving skills, and emotional regulation. When a child overcomes a challenge with support, the brain strengthens pathways for resilience.

Why It Matters

Positive stress teaches children:

• “I can do hard things.”
• “I can ask for help.”
• “Challenges are part of learning.”

In a world that often pushes children toward perfection, positive stress reminds us that struggle is not failure — it’s growth.

Tolerable Stress:
Hard Moments That Require Support

Tolerable stress refers to more serious challenges that can still be managed with the help of stable, supportive adults. Examples include:

• A family move
• The loss of a pet
• A medical procedure
• Temporary financial strain

These experiences can be emotionally intense, but when children feel seen, soothed, and supported, their brains recover and continue to develop in healthy ways.

What Helps

• Predictable routines
• Open conversations about feelings
• Reassurance from trusted adults
• Opportunities for play and rest

Tolerable stress becomes a story of coping and healing, not harm.

Toxic Stress:
When Stress Becomes Harmful

Toxic stress occurs when a child experiences strong, frequent, or prolonged adversity without adequate adult support. This might include:

• Chronic poverty
• Exposure to violence
• Ongoing discrimination
• Caregiver mental health challenges
• Unstable housing
• Persistent family conflict

Without buffering relationships, the body’s stress response stays activated for too long. Over time, this can disrupt:

• Executive function
• Emotional regulation
• Memory and attention
• Immune and metabolic systems

Toxic stress is not a reflection of a child’s abilities or character — it is a systemic failure that requires community‑level solHow Families and Schools Can
Buffer Stress

The most powerful antidote to harmful stress is a stable, nurturing relationship with at least one caring adult. Children don’t need perfection — they need presence.

Here are some of the Ways Adults Can Help

• Connect before correcting. Emotional safety comes first.
• Name feelings. “You’re frustrated, and I’m here with you.”
• Build predictable routines. Consistency reduces anxiety.
• Create space for play. Play is the brain’s natural stress‑relief system.
• Partner with teachers. Shared understanding strengthens support.
• Seek community resources when needed. Support is a sign of strength, not weakness.

What Schools Can Do

Schools play a critical role in shaping children’s stress experiences. Environments that are emotionally safe and culturally responsive help buffer stress for all students — especially those facing systemic barriers.

Schoolwide Practices That Help

• Trauma‑informed teaching
• Culturally sustaining curriculum
• Restorative discipline practices
• Access to counselors and mental health supports
• Strong family‑school partnerships
• Opportunities for movement, creativity, and play

The Takeaway

Stress is not the enemy — unsupported stress is. Positive stress builds resilience. Tolerable stress becomes manageable with caring adults. Toxic stress requires collective action and systemic change. When families, educators, and communities work together to create supportive environments, we give children the foundation they need to grow into confident, capable, emotionally healthy learners.
