Poor breathing is a problem for many people living with anxiety. In some cases, anxiety can be brought on by poor breathing habits, but more commonly the experience of anxiety results in the creation of poor breathing habits by constantly stimulating the autonomic nervous system, ultimately changing the way you breathe.
Poor breathing habits can lead to a variety of issues, the most common of which is hyperventilation. Hyperventilation is responsible for many of the symptoms of anxiety attacks, including chest pain and rapid heartbeat. The solution to poor breathing is, of course, learning healthier breathing habits.
