Lower cortisol in high-stress school settings

How do you keep pace with the curriculum when more students are arriving dysregulated, depleted or already close to overload – and when teacher rates of depression, anxiety and stress are three times the national norm?

There is no single answer to such a complex situation, but one of the few things school leaders can actively shape is the physical environment that staff and students experience each day.

Complexity in the classroom

Australian data shows that

That’s without counting the children navigating parental separation or divorce, grieving the loss of a grandparent or the 20% of under-14s whose families are experiencing housing stress.

At the same time, schools are navigating a “national teacher workforce crisis” (according to our education ministers) while UNSW reports that 90% of teachers are experiencing extreme stress and 70% say their workload is unmanageable.

When a classroom keeps the stress response switched on

Cortisol is one of the body’s main stress hormones. In short bursts, it helps mobilise attention and energy. When stress is sustained, the picture changes.

A 2023 review in Frontiers in Endocrinology summarised a large body of evidence linking cortisol and stress physiology to changes in cognitive functioning. To put it another way, students experiencing sustained stress may struggle to learn. An overloaded nervous system can translate to distraction, meltdown or shutdown.

For some students, the environment itself is part of the problem: fluorescent lighting, scraping chairs, crowded visual displays, reverberant noise, frequent transitions, and unpredictable movement can all trigger sensory overload.

What changes when the environment changes

If the environment is part of the problem, it follows that it can also be part of the solution. When the body remains in a heightened stress state, it creates the conditions that keep cortisol elevated. Supporting the nervous system to settle helps ease that broader stress response.

Once stress levels reduce, self-regulation becomes more manageable. That’s critical as self-regulation is strongly associated with academic performance, classroom behaviour and social participation.

A calming sensory room offers overstimulated students (and staff!) a room to reset

A sensory room is a controlled environment designed to reduce sensory load and support regulation. That includes therapeutic lighting, reduced or managed sound, and tactile or proprioceptive input that gently soothes the senses.

These low-stimulation, restorative environments can help to calm breathing and heart rate, even in healthy individuals. Students may enter the room feeling agitated or overwhelmed, but gradually, their breathing slows, their body softens, and they gain capacity for engagement and learning.

They don’t return to the classroom in the same state, nor are they amped up the way they might be after a typical breaktime. A calming sensory room supports students to return to the classroom with renewed capacity for participation.

A practical step in a complex system

Cortisol is rarely discussed in staff meetings, but its effects are visible every day, in restlessness, shutdown, escalation and fatigue.

A sensory room does not replace teaching expertise, clinical support or broader wellbeing strategies. It sits alongside them, offering students a place to soothe their senses, ease their overwhelm and access a calmer version of themselves that’s more ready to learn.
