Catecholamines are a group of hormones your adrenal glands release in response to physical or emotional stress. They include epinephrine (adrenaline), norepinephrine and dopamine. After using the hormones, your body eliminates the remaining waste through urine.
Catecholamines enter the bloodstream to trigger your body’s fight or flight response. This natural reaction to stress includes:
- Releasing adrenaline for extra energy.
- Increasing your heart rate and blood pressure.
- Heightening your mental alertness.
- Boosting blood flow to the muscles and brain.
