Re: Lightheadedness when reading something stressful or having stressful thoughts
When we're stressed or anxious our normal breathing becomes altered and we then breathe a little quicker which leads to over-breathing, and this would induce the lightheadedness. Paradoxically, when we do deep breathing exercises this can also produce lightheadedness. It's all about the balance between oxygen and carbon dioxide levels. Many years ago, doctors would recommend breathing into a paper bag to restore the balance. It worked too!
