Catecholamines

Catecholamines are a group of chemicals produced by the adrenal glands in response to stress. The main types include adrenaline (epinephrine), noradrenaline (norepinephrine), and dopamine. They play vital roles in the body's "fight or flight" response, increasing heart rate, blood pressure, and energy availability. When you’re excited or under stress, these hormones help prepare your body to react quickly. Imbalances in catecholamines can affect mood and health, relating to conditions like anxiety, depression, or high blood pressure.
