While an average adult's normal body temperature is 98.6°F (37°C), this can fluctuate throughout the day and with various internal and external factors. Understanding **what can raise my temperature** is crucial for distinguishing between a healthy immune response and a more concerning issue that requires medical attention.

Yes, a fever can be the only symptom, particularly in the initial stages of a viral infection. Approximately 15-30% of fever of unknown origin (FUO) cases are caused by an underlying infection, even when other signs are not immediately present.

While a sustained high temperature is often the focus, fevers that fluctuate are a common occurrence. The medical term for **what is a fever coming and going called** depends on its specific pattern, with intermittent and relapsing being key classifications used by healthcare professionals.

The long-held average normal body temperature of 98.6°F is actually outdated, with many healthy adults now hovering closer to 97.9°F. This means that for many people, a temperature of 99°F is simply within the normal daily fluctuation and not a cause for concern, making the question 'Is a 99 degree fever normal for adults?' a common but often unnecessary worry.

When your body temperature rises suddenly, it's often a sign that your immune system has been activated to fight an invader. A high temperature is not an illness itself but a symptom, leaving many to wonder, **what can cause a sudden spike in fever**?

While the long-held standard for 'normal' body temperature was 98.6°F, more recent studies suggest the average is closer to 97.9°F for adults, and a person's baseline temperature can fluctuate throughout the day. This evolving understanding of baseline temperature is crucial for determining **what is considered low-grade fever in Fahrenheit**, which is an elevated but not clinically significant body temperature.

The normal human body temperature is approximately 98.6°F (37°C), but it can fluctuate throughout the day due to normal physiological processes. A significant increase, however, often indicates an underlying issue, leading many to ask, **what causes my temperature to go up**? The answer involves complex biological processes regulated by the brain's hypothalamus.

Did you know a fluctuating fever is often a sign of a dynamic battle taking place inside your body? Understanding **why do fevers spike up and down** offers a critical look into how your immune system combats an infection, providing insight into your health.

According to the World Health Organization, fever is one of the most common medical symptoms, signaling the body's natural fight against infection. But not all fevers are the same. To understand your body's response, it's crucial to know: What are the 3 types of fever? The main classifications are continuous, intermittent, and remittent.

According to the American Academy of Family Physicians, recurrent fevers are officially defined as three or more febrile episodes within a six-month period. Understanding **why does recurrent fever occur?** requires a look at a range of conditions, not just common infections, to pinpoint the root cause and find effective management.
