Noradrenaline

Noradrenaline, also known as norepinephrine, is a chemical messenger in the body that plays a key role in the fight-or-flight response. It is produced by nerve endings and the adrenal glands, helping to increase heart rate, blood pressure, and blood sugar levels during stressful situations. Noradrenaline influences alertness and focus in the brain, preparing the body to respond quickly. It also constricts blood vessels, directing blood flow to muscles and vital organs. Overall, noradrenaline helps the body respond effectively to stress or danger while also supporting attention and awareness.
