The stress response and chronic stress

Last reviewed 3 August 2026. How we write this.

Stress is a normal adaptive response; the problem is sustained load without adequate recovery or control.

The autonomic and hormonal stress systems mobilise attention and energy. Chronic stress can affect sleep, mood, behaviour and physical symptoms.

Useful response layers

Reduce avoidable demands where possible.
Protect sleep, meals, movement and connection.
Use paced breathing or relaxation for acute arousal.
Seek professional support when distress persists or function falls.

Stress should not be used to dismiss new physical symptoms without assessment.
