Epinephrine — commonly called adrenaline — is our bodies’ naturally occurring hormone used during the natural stress response. When something stressful occurs, the adrenal gland releases adrenaline into the bloodstream combined with a few other hormones such as cortisol.
The heart understands this as a message to pump harder, which automatically increases blood pressure, narrowing blood vessels and increasing the blood flow to important muscles and activating body’s „fight or flight“ response in cases of perceived threat.
In individuals with chronic stress, this response is constantly triggered and physical and psychological consequences can be detrimental. This is why the body often becomes exhausted. The abundance of adrenaline and cortisol can be the cause of decreased immunity and many other health issues.
Epinephrine can be triggered in response to both positive and negative stress. While positive stress (excitement) can help to maintain vitality, you have to balance how much stress is triggered overall.
