Anxiety is more than just a mental struggle—it can produce significant physical symptoms. People experiencing anxiety often notice heart palpitations, muscle tension, and even digestive problems like nausea or irritable bowels.

According to the Mayo Clinic, anxiety’s physical effects are wide-ranging, highlighting the close bond between mental and physical wellbeing.
