It might make you nervous about your worry, which is paradoxical. Anxiety is a condition of negative arousal; the key to overcoming it is to use that arousal in a constructive way, transforming anxiety into enthusiasm. Excitement is a comparable high activation state, making it much easier to transition to. In fact, research has shown that intense exercise can help reduce symptoms of anxiety. Excessive excitement or stress can lead to anxiety. This makes sense because anxiety is caused by an imbalance of chemicals in the brain. When there is too much activity in one area of the brain it can cause anxiety. For example, if you are prone to anxiety you may find activities like dancing or extreme sports stressful because they use up too much adrenaline. The good news is that anxiety can be reduced by reducing the stressors that cause it and increasing the time spent doing things you enjoy. It's also helpful if you can learn how to deal with these situations effectively so you don't cause more anxiety later. Cognitive behavioral therapy (CBT) has been shown to be very effective in treating anxiety disorders. CBT focuses on learning how to respond rather than react, which means learning how to cope with stressful situations. For example, if you are anxious when asked to speak in public you could practice speaking in front of small groups before big events. This will help you develop strategies for coping when you feel nervous. Then when the time comes you will be better able to handle it.
