Adrenaline

Adrenaline, also known as Epinephrine, is both a hormone and neurotransmitter — but its primary role is as a stress hormone, released by the adrenal glands in response to the  fight-or-flight response (FFR). In flight mode, the body responds with a surge of adrenaline to boost the stamina to run from danger longer and faster than is typical. Adrenaline is made and released quickly, creating body sensations like sweaty palms, faster breathing, racing heart, and slower digestion. Muscles use the glycogen stored in the body to help with strong, extended muscle contractions. An adrenaline rush can feel like anxiousness, nervousness, or excitement as body and mind prepare — it’s meant to keep one focused and ready to act.
