One of the most powerful strategies for reducing stress according to Stuart Shanker’s Self-Reg framework, is often the simplest: human connection. We frequently think of self-regulation as something we do alone, but our nervous systems were never designed to regulate in isolation. They evolved to regulate together.

When a child seeks a parent offering a calm embrace, the reassuring presence of a trusted teacher, or when a colleague/peer listens without judgment, something remarkable is happening beneath the surface. The brain and body begin shifting away from survival and toward safety.

This process, known as co-regulation, is supported by an intricate nervous system fueled by neurochemicals. Warm, attuned interactions stimulate the release of oxytocin, often called the “bonding hormone.” Oxytocin dampens activity in the brain’s threat-detection systems, reduces stress hormone release, and promotes trust and social engagement.

Positive social connection also activates the //brain’s endogenous opioid system, producing feelings of comfort, security, and emotional warmth. These naturally occurring opioids help soothe emotional distress and reinforce the desire to remain connected with supportive people. Healthy relationships also influence dopamine. Human connection becomes intrinsically rewarding, motivating us to seek supportive relationships again and again.

At the same time, calming social experiences enhance serotonin signaling, contributing to emotional stability, patience, and behavioural flexibility. In contrast, chronic isolation and unresolved stress elevate cortisol and other stress mediators, making it increasingly difficult for the prefrontal cortex to support attention, problem-solving, and emotional regulation.

This is why relationships matter so profoundly in schools. Before we can teach, redirect, or problem-solve, we must first help students experience safety. A calm voice, genuine curiosity, predictable routines, eye contact, and compassionate presence are not merely acts of kindness; they are biological interventions that reshape the chemistry of the brain thereby seeking calm before cognition, or to regulate before you educate.

Self-Reg reminds us that behaviour is often a window into stress, not character. By becoming a source of calm rather than another source of demand, educators activate the neurobiology of connection. In doing so, they help children borrow a regulated nervous system through what Stuart Shanker refers to as an Interbrain connection.

Connection is not the reward for being regulated. Connection is one of the primary mechanisms through which regulation becomes possible.

Cognitive Dynamics can help change the way you think about connecting for co-regulation.
