Stress is a powerful force that can affect both our emotional and physical health. While many of us associate stress with symptoms like headaches or muscle tension, it can also lead to something more surprising: a fever. This type of fever, known as psychogenic fever, occurs as a result of psychological stress, and it can be just as intense as a fever caused by physical illness. In this article, we explore what psychogenic fever is, how stress can cause a fever, and the steps you can take to manage it.

What Is Psychogenic Fever?

Psychogenic fever is a condition where the body experiences a rise in temperature due to psychological stress rather than an infection or illness. The term "psychogenic" refers to the fact that the fever is rooted in a psychological cause, as opposed to a physical one. Unlike a regular fever, which is typically triggered by infections, psychogenic fever is associated with stress-induced physiological changes.

A study conducted in 2021 found that individuals who were highly stressed—such as those dealing with the anxiety of the COVID-19 pandemic or preparing for a surgical procedure—developed fevers as a result of their emotional distress. These fevers can vary in severity, from low-grade fevers that last for months to higher fevers reaching up to 105.8°F during particularly stressful episodes.

Psychogenic Fever vs. Regular Fever

The primary difference between psychogenic fever and regular fever lies in their causes. Regular fevers are usually caused by infections, medications, or inflammatory conditions. In contrast, psychogenic fever is solely triggered by psychological stress.

Psychogenic fevers also lack some common symptoms of regular fevers, such as chills, muscle aches, and sweating. Anti-inflammatory drugs, which are often effective for treating regular fevers, generally do not reduce psychogenic fever.

How Stress Leads to a Fever

Stress has long been known to affect the body in many ways, from headaches and digestive issues to sleep disturbances and increased heart rate. However, stress-induced fevers, or psychogenic fevers, are less commonly discussed. So, how exactly can stress cause a fever?

Stress and Its Effects on the Body

When the body is under stress, the adrenal glands release stress hormones such as cortisol and adrenaline. These hormones prepare the body for a "fight-or-flight" response, which helps you react to the stressor at hand. However, prolonged or chronic stress can disrupt the body’s natural balance, leading to immune system suppression. A weakened immune system can make the body more susceptible to infections, which can, in turn, trigger a fever.

Additionally, stress has a direct impact on body temperature regulation. While there is little scientific evidence to definitively prove that stress itself can directly raise body temperature, the physiological changes stress causes may indirectly result in a fever. Stress can increase inflammation and alter blood flow, both of which may contribute to a rise in body temperature.

Factors That Contribute to Stress-Related Fevers

  • Chronic stress: Long-term stress from work, relationships, or personal issues can lead to a sustained rise in cortisol levels, which may, over time, trigger a psychogenic fever.

  • Emotional or mental health issues: Anxiety, depression, and other mental health conditions are commonly associated with stress-induced fevers. The psychological distress caused by these conditions can elevate the body’s temperature.

  • Sleep deprivation: Lack of sleep is a major stressor for the body. Research shows that sleep deprivation can increase cortisol levels, which may lead to a higher body temperature.

How to Manage a Psychogenic Fever

If you are experiencing a fever as a result of stress, there are several steps you can take to manage your symptoms. The key is to address the underlying cause of the stress and adopt strategies that promote relaxation and wellness.

Identify and Address the Source of Stress

The first step in managing stress-related fevers is identifying what is causing the stress in your life. Common sources of stress include:

  • Work-related challenges, such as deadlines, job changes, or conflicts with coworkers

  • Personal challenges, including relationship problems, financial issues, or family responsibilities

  • Major life changes, such as moving, getting married, or experiencing a loss

Once you identify the source of stress, take action to address it. This may involve setting boundaries, delegating tasks, or seeking professional help to manage the stressor.

Practice Relaxation Techniques

Relaxation techniques can help lower stress levels and reduce the likelihood of a stress-induced fever. Consider incorporating the following practices into your routine:

  • Deep breathing exercises: Deep breathing can help reduce the body's stress response and promote relaxation. Try inhaling deeply for a count of four, holding your breath for four counts, and exhaling slowly for a count of four.

  • Yoga and meditation: Mindfulness practices such as yoga and meditation have been shown to reduce stress and lower cortisol levels. These activities help you relax and focus on the present moment.

  • Progressive muscle relaxation: This technique involves tensing and then relaxing muscle groups in the body. It helps relieve tension and can reduce the physical symptoms of stress.

  • Massage therapy: Regular massages can help alleviate stress by soothing tense muscles and promoting relaxation.

Adopt Healthy Lifestyle Habits

Maintaining a healthy lifestyle is crucial for managing stress and preventing stress-related fevers. Some habits to consider include:

  • Exercise regularly: Physical activity helps reduce stress hormones in the body and promotes overall well-being. Aim for at least 30 minutes of moderate-intensity exercise five days a week.

  • Eat a nutritious diet: A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help support your immune system and combat stress.

  • Prioritize sleep: Getting enough sleep is essential for stress management. Aim for seven to nine hours of sleep each night to help your body recover and recharge.

Seek Professional Help

If stress is taking a toll on your mental and physical health, consider seeking professional help. A mental health professional, such as a therapist or counselor, can help you develop coping strategies and manage stress more effectively.

If you continue to experience unexplained high body temperatures or other concerning symptoms, consult a healthcare provider. They can conduct tests to rule out underlying conditions and help you find the right treatment.

A Quick Review

Stress-related fevers, also known as psychogenic fevers, can occur as a result of prolonged psychological stress. Although stress may not directly cause a fever, it can weaken the immune system, making the body more susceptible to infections that trigger a fever. Managing stress through relaxation techniques, exercise, and healthy lifestyle habits can help reduce the likelihood of stress-induced fevers.

If you experience persistent high body temperature or other concerning symptoms, consult a healthcare provider to determine the underlying cause and receive appropriate treatment.
