Some stress hormones are very important. They regulate metabolism, mood, body temperature, blood pressure, appetite, digestion and other important processes in your body. The stress hormones cortisol and adrenaline play an important role in the stress response. If you are stressed, you have high levels of both hormones in your blood stream. You can either lower or increase your level of these stress hormones with food, exercise, meditation, stress reduction techniques and many other ways. Cortisol and adrenaline are your body's way of trying to calm itself down, get ready for the next thing. It's basically like a "fight or flight" response, where the body tries to get the adrenaline to slow down the stress, but you need to give it to it. We all feel this and feel stressed, but when we are stressed out, cortisol and adrenaline is the first thing that comes to mind. If you have not had any exercise or meditation recently, this may be what you feel. If you are really stressed out, and don't know what to do, the idea is to take a few minutes and get your mind off things, so you can think about something positive and calming to take away the stress.
