Stress has a bad reputation, but it's a tool. Your body's stress response evolved to get you ready for a challenge. The trouble starts when it never switches off.
What happens in your body
When your brain spots a threat, often before you're consciously aware of it, thanks in part to the amygdala, your body releases adrenaline and cortisol. Your heart beats faster, you breathe quicker and more sugar goes into your blood. You're ready to act.
That's useful in short bursts. A bit of pressure can sharpen you: the old Yerkes–Dodson idea says performance rises with arousal up to a point, then falls if it climbs too high. The problem is chronic stress, weeks or months of it, which is linked to poorer sleep, memory and health.
What emotions are for
Emotions are fast summaries that tell you what matters and nudge you to act: fear says "be careful", anger says "something's unfair", sadness says "you've lost something". Paul Ekman proposed six basic emotions with expressions recognised across cultures (happiness, sadness, fear, anger, surprise and disgust), though how universal they are is still debated.
Strategies with good evidence
- Reappraise. Change the story, not just the face. Seeing a racing heart before an exam as "my body getting ready" works better than trying to force calm. In one set of studies, people who said "I am excited" before a stressful task did better than those who told themselves to calm down.
- Name it. Putting a feeling into words ("I'm anxious about tomorrow") tends to turn its volume down. This is affect labelling.
- Breathe slowly, with a longer out-breath. It switches on the body's calming system.
- Move. Regular exercise reliably helps mood and anxiety, and even a short walk helps for a while.
- Talk to someone. Social support is one of the strongest buffers against stress.
What tends not to help: suppressing feelings (hiding them without changing them), and ruminating, going round and round a problem without moving toward an answer.
This deck is about everyday stress. If stress or low mood is getting in the way of daily life, talk to a doctor or a mental health professional.
