Can Anxiety Weaken Your Immune System?

When you are overwhelmed with worry, fear, or stress, it’s common to feel exhausted or run down. Persistent fatigue can, in turn, be both a symptom of and a risk factor for certain physical illnesses. Does this mean that anxiety can weaken the immune system?

What Is Anxiety?

Before we dive into the relationship between anxiety and the immune system, let’s take a moment to review what, exactly, anxiety is.

Anxiety is a general term that can refer to several distinct mental health disorders. The anxiety section of fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes the following disorders:

  • Generalized anxiety disorder
  • Specific phobia
  • Social anxiety disorder
  • Panic disorder
  • Selective mutism
  • Separation anxiety disorder
  • Agoraphobia

All anxiety disorders are characterized by excessive fear or worry. The separate types of anxiety disorders are differentiated primarily by what types of events, experiences, or circumstances can prompt the onset of symptoms. 

Does Anxiety Weaken Your Immune System?

Research indicates that anxiety can have a negative effect on the immune system. But experts have not yet identified a common, universal connection between anxiety and the immune system. 

For example, the authors of a 2015 article in the journal Current Opinion in Psychology reported that “psychological stress has been linked empirically with dysregulation of facets of the human immune system.” However, the authors of this article noted, the ways that excessive stress can impact the immune system appear to vary from person to person. 

Several sources, including the Mayo Clinic, have identified cortisol as a contributor to stress-related problems in the immune system. When a person encounters what they believe to be a threat, their body’s reaction includes the production of several hormones, including adrenaline and cortisol. (It is important to understand that the threat does not have to be real for this response to occur – just that the person believes that they are in danger, which is what happens when a person has an anxiety disorder.)

In general, the body’s reaction to perceived threats is to shut down non-essential functions so that maximum energy can be directed toward the “fight or flight” response. Among cortisol’s role in this process is altering how the immune system operates.

Ideally, this type of reaction is relatively rare. However, people who have anxiety disorders may constantly feel that they are in peril, which means their body will engage in this response over and over again. The cumulative impact of this perpetual emotional distress can include an erosion of the body’s ability to protect itself from diseases and illnesses. 

How Else Does Anxiety Impact the Body?

The physical effects of anxiety aren’t limited to the immune system. Depending on which type of anxiety disorder a person has developed, they may also have the following types of physical symptoms:

  • Excessive perspiration
  • Elevated heart rate
  • Tingling in the hands and feet
  • Dizziness and lightheadedness
  • Shortness of breath
  • Sensation of being choked or smothered
  • Chest pain
  • Nausea

If a person has panic disorder, symptoms such as the ones listed above can occur at any time, with little to no warning. These symptoms can be severe enough to make a person believe that they may be about to die.

Other types of anxiety disorders can also cause symptoms like the ones listed above. For example:

  • Someone who has specific phobia may develop many distressing physical symptoms when they are exposed to a certain animal, object, or circumstance. 
  • People who have social phobia may develop these symptoms when they are placed into a situation where they fear that they may be judged negatively by others.
  • Individuals who have agoraphobia may suffer from these types of physical responses when they are among a crowd of people, in wide open spaces, or in certain other environments.
