Your body doesn't distinguish between 'important match' and 'danger'. It releases adrenaline, increases heart rate and breathing, and diverts blood from your hands and digestion. That's why your hands are cold and your stomach feels tight.
That's a readiness to perform, not a weakness
Players who feel no tension before games are rarely the best players. There's a zone where activation helps – too little is just as bad as too much. Your job isn't to be calm. Your job is to land in your zone.
When it turns sour
- You read the symptoms as proof that you're about to fail.
- Your focus is on yourself instead of the game.
- You try to push the tension away – and make it bigger.
What actually helps
Two things, in this order: lower arousal (long exhale) and redirect attention (a specific word for your first task). Both take less than two minutes and can be done in the changing room.
"Stay calm" isn't an instruction your brain can do anything with. "Four in, eight out, then make contact" is.
