4. Adrenaline
Have you ever heard someone say that they have just experienced an adrenaline rush? Or, have you heard about people describe themselves or others as adrenaline junkies? Let’s backtrack a little and define adrenaline before proceeding. Adrenaline is one of the hormones produced by the body – the adrenal gland if you want to be more specific – and this is the hormone that’s most often tied to the body’s “fight or flight response”, or the rush that you experience when you are about to go through some kind of physical excitement – or if you get the fright of your life.
An adrenaline rush in the most simple terms is the hormone being released in your body as preparation for your body to undergo some kind of physical strain: This is your body’s way of getting ready for it. Of course, only one of the things caused by adrenaline is heart palpitations.
