noradrenaline (norepinephrine)

Noradrenaline, also called norepinephrine, is a chemical messenger in the body that functions both as a hormone and a neurotransmitter. It is involved in the body's fight-or-flight response, preparing you to react to stress or danger by increasing heart rate, blood pressure, and energy supplies. It helps regulate attention, focus, and alertness, and influences mood. Produced mainly in the adrenal glands and nervous system, noradrenaline plays a key role in responding to stress and maintaining overall alertness. Its balanced function is essential for emotional stability and effective stress management.
