These are two interchangeable terms for the hormone that is secreted from the adrenal gland when our body perceives a threat. It is responsible for the “fight or flight” reaction. Epinephrine activates the body’s energy reserves thus keeping us safe by allowing us to fight for survival, or to flee from dangerous situations. It causes increased heart rate; blood pressure and blood flow to the brain, muscles, lungs and heart. Unfortunately the body produces the same response to real physical threat & mental or emotional stress. After an extended stressful time the adrenal glands, and epinephrine becomes depleted and an individuals shows signs of adrenal fatigue. They become worn out and unable to respond mentally, emotionally and physically to situations where quick, efficient action is required. This situation is common in today’s society where everything needed to be done yesterday and we feel as though we are constantly on the go. Many people suffer from low energy, depression, anxiety, poor sleeping and eating patterns and hypertension, all common symptoms of adrenal depletion.
