Adrenaline, also known as epinephrine, is your body’s ultimate “fight or flight” hormone, a natural stimulant produced by the adrenal glands in high-stress or exciting situations. Picture it as your body’s own action movie hero, ready to jump into action when danger is sensed, boosting your heart rate, pumping up your energy, and sharpening your focus—all to prepare you for rapid response. It’s like a built-in alarm system that gives you the superpowers you need, exactly when you need them, whether it’s to run faster, think quicker, or react with lightning speed.
