Psychological stress has a well-documented impact on body physiology, with studies showing an increase in core temperature due to emotional events. This phenomenon is a direct answer to the question: **Does your temperature go up when you're nervous?**

Research has shown that strong psychological and emotional stress can trigger a real, non-infectious rise in body temperature known as psychogenic fever. This phenomenon reveals the surprising answer to whether it **is it possible to cry so hard you get a fever?**

The sympathetic nervous system is responsible for the body’s involuntary “fight-or-flight” response, a crucial survival mechanism that rapidly prepares you for action. This physiological reaction is precisely **what does sympathetic mean in medical terms**, distinguishing it from normal, resting body functions.

The sympathetic nervous system, a key part of your body's automatic stress response, can cause a near-instantaneous cascade of hormonal changes. In simple terms, this system is responsible for the 'fight or flight' reaction that prepares your body to confront or escape perceived danger. This guide breaks down exactly what does sympathetic mean for your overall health.

Over 31% of US adults experience an anxiety disorder at some point, and one lesser-known symptom can be a physical sensation of surging. This guide details what would cause surging, exploring a range of possible physiological and psychological explanations for this unsettling bodily feeling.

Research has shown that an elevated heart rate shortly after experiencing a traumatic event is associated with a higher likelihood of developing post-traumatic stress disorder (PTSD) later on. This physiological reaction is a fundamental part of the body's stress response and definitively answers the question, "Can trauma raise heart rate?".

The hormone responsible for the body's 'fight or flight' response is known by two distinct names, and Americans use both depending on the context. So, what do Americans call adrenaline? The answer is more complex than you might think, involving a mix of medical and common terminology.

In 1982, Angela Cavallo lifted a 1964 Chevy Impala off her son to free him, a confirmed and remarkable example of what's known as 'hysterical strength'. This incredible story answers the question: Did a woman really lift a car to save her child?

Physiological research indicates that emotional and psychological stress can induce a rise in core body temperature, a phenomenon known as stress-induced hyperthermia. So, does being nervous bring up your body temperature? Yes, the body's fight-or-flight response is the primary mechanism behind this reaction.
