Stress is your body’s reaction to pressure, and it all starts when the stress response is triggered.
21 The body’s response to stress is actually an important survival mechanism handed down from our ancestors. Although nowadays, it’s more likely to be triggered by psychological threats such as running late for a meeting, rather than a sabre-toothed tiger.
When you sense danger – like a car hurtling towards you – your brain prompts the adrenal glands to release the stress hormones adrenaline and cortisol.22
These powerful hormones then activate the sympathetic nervous system, which causes rapid physical changes that are designed to help you escape.
That restless, jittery, stomach-churning sensation you experience when you’re stressed is the infamous ‘fight or flight’ response, helping your body get ready to leap into action.40
But a little stress can still be a good thing; it can keep you laser-focussed in a dance battle, and that jittery feeling before a job interview can help you find focus and power through.
