In our approach to dealing with people with adrenal fatigue, this is a very common complaint, so what is really going on? When you exercise, several things are happening to your body. One of the most important things is the release of adrenaline in order for you to do aerobic exercises, for example. You are not going to be able to stand up and run without an output of norepinephrine, as well as epinephrine also called adrenaline. So many people feel wonderful, they feel great during the exercise high. Why? Because the adrenaline is helping their heart pump, they’re increasing oxygenation, they basically don’t have the fatigue because the adrenaline is taking over as a large result, and the adrenaline is driving the body.
