When stress and anxiety “disguise” themselves as common physical illnesses: how to identify them

A feeling of physical discomfort similar to that of a cold or the flu can have an unexpected origin: anxiety. According to experts cited by Prevention, this mental health disorder usually manifests itself through physical symptoms easily confused with common illnesses, which makes both its detection and adequate treatment difficult. Anxiety, the most common mental health problem in the United States, goes beyond simple worry or nervousness. Psychiatrist David Merrill, from the Pacific Neuroscience Institute, explained to Prevention: “In addition to emotional symptoms, many people experience irritability, fatigue, restlessness, and a general feeling of imbalance.” However, physical symptoms can be even more disconcerting, mimicking conditions like colds, allergies, or a hangover. Merrill warned that these mental and physical symptoms often form a cycle, in which anxiety triggers bodily discomforts and these, in turn, intensify anxiety.

Physical Symptoms of Anxiety

Among the most frequent physical manifestations, specialists highlight the acceleration of heart rate. Clinical psychologist Joseph Laino, assistant professor at the Grossman School of Medicine at NYU, specified that anxiety activates the body’s alarm system. The amygdala detects threats and triggers the release of substances such as cortisol and adrenaline, preparing the body to react. This process elevates heart rate and blood pressure, and can even cause palpitations. Laino emphasized that, although this reaction is essential for survival, it can be harmful if it is prolonged excessively. Another common manifestation is the alteration of body temperature. Merrill indicated that the hypothalamus, responsible for regulating body heat, responds to anxiety with chills, excessive sweating, or both symptoms at the same time. In addition, muscle activation during these episodes can produce unusual muscle pains. Respiratory distress represents another relevant symptom. Merrill explained that the increase in heart rate leaves less oxygen available, forcing the lungs to work harder. In situations of extreme anxiety, such as a panic attack, it is common to experience tachycardia and a feeling of shortness of breath. The specialist recommended practicing deep breathing to alleviate both symptoms, although he insisted on seeking immediate medical attention if chest pain persists or worsens.
