Poker Physiology
What's happening to your body during a hand?

Your body is an intricate and delicate system designed to sense threat, and biologically programmed to avoid it. Your nervous system is a vast information highway that runs every cellular process in the body. From breathing and your heartbeat to movement and thought, your nervous system affects every process of your body.
So what’s happening in your body during a hand?
Because of the unknown outcomes, the variability of chance, and the sheer financial risk, poker is stressful by design. Let me be clear about what I mean. Let’s define stress as a physical, emotional or chemical factor that causes bodily or mental tension and let’s avoid judgment of whether stress is good or bad. Stress simply exists and we live in relation to it.
So during a hand, regardless of age, gender, ethnicity or experience at the table, a body responds to stress exactly the same. Stress is a threat and regardless of the size, shape, cause or intensity the body reacts with a Fight or Flight response.
Originally intended to protect you, the fight or flight response causes a release of hormones that:
- Increase your heart rate
- Increase your blood glucose (blood sugar)
- Put you in a “ready” state
Ever have the feeling that you need caffeine, sugar and other stimulants to keep you on your toes? You’re simply prolonging the “high” your body has already initiated.
