Definition & Meaning of "adrenaline"

What is "adrenaline"?

Adrenaline, also known as epinephrine, is a hormone produced by the adrenal glands. It plays a crucial role in the body's response to stress and emergencies. When released into the bloodstream, adrenaline triggers various physiological changes, such as increased heart rate, elevated blood pressure, and heightened mental alertness. These effects prepare the body for a "fight-or-flight" response, helping to mobilize energy and enhance physical performance. Adrenaline is an essential component of the body's stress response system and contributes to our ability to cope with challenging situations.
