Adrenaline

Adrenaline, also known as epinephrine, is a hormone produced by the adrenal glands in response to stress or danger. It prepares your body for a quick response by increasing heart rate, expanding airways, and redirecting blood flow to muscles. This "fight-or-flight" response boosts alertness and energy, helping you react swiftly to challenging situations. Adrenaline also causes pupils to dilate and releases energy stores, providing the necessary fuel for action. It plays a crucial role in short-term physical readiness but is part of your body's natural response to stress.
