Health anxiety leads us to assume all or most symptoms or bodily sensations are indicative of a serious disease. However, our bodies are "noisy." Learn about the common sources of body noise so you can reshape your beliefs around this and refrain from automatically assuming you have a serious disease.
With health anxiety, we have unhelpful or inaccurate core beliefs about health and illness. These beliefs lead us to process information in a biased way. We tend to seek out "evidence" of our belief (e.g. that serious disease is everywhere) and we ignore or dismiss evidence to the contrary. It can be helpful to use a CBT technique and track your thoughts and assumptions in a thought record so that you can identify these patterns.
With health anxiety, an event happens, we have thoughts about that event, and then react to those thoughts. Learning to evaluate automatic thoughts and identify cognitive distortions is a critical skill for improving health anxiety. Cognitive behavioral therapy helps to improve health anxiety by reshaping dysfunctional thinking patterns, beliefs, and behaviors.
