Elevated body temperature can be a source of concern for many individuals, especially in the context of recent health crises like the COVID-19 pandemic. Understanding whether an elevated temperature constitutes a fever or is simply a normal variation is crucial for appropriate health management.

In general, a normal body temperature for adults typically ranges from about 36.1°C to 37.2°C (97°F to 99°F). A temperature of 37.5°C (99.5°F) is considered to be on the higher end of the normal range, but it can also indicate a low-grade fever, especially when accompanied by other symptoms. According to medical definitions, a fever is usually defined as a body temperature of 38°C (100.4°F) or higher. Therefore, your readings of 37.1°C to 37.7°C are not classified as a fever, but they do suggest that your body is experiencing some form of stress or response.

The symptoms you describe—sweating in your hands and feet, discomfort in your throat and tonsils, and feelings of fatigue—are noteworthy. These symptoms could indicate a mild infection or inflammatory process, which could be causing your body temperature to rise slightly. The presence of sweating can also be a physiological response to regulate body temperature, as your body attempts to cool itself down.

It is essential to consider the context of your symptoms. If you have been exposed to someone with an infectious illness, or if you have other symptoms such as a cough, body aches, or gastrointestinal issues, it may be prudent to seek medical advice. The throat discomfort you mentioned could suggest a viral or bacterial infection, such as pharyngitis or tonsillitis, which can sometimes cause a mild fever.

Moreover, environmental factors can also play a role in body temperature regulation. For instance, if you are in a warm environment or have been physically active, your body temperature may rise temporarily. The body's thermoregulation system, primarily controlled by the hypothalamus, works to maintain a stable internal temperature through various mechanisms, including sweating and altering blood flow to the skin.

If your symptoms persist or worsen, or if you develop a higher fever, it would be advisable to consult a healthcare professional. They can perform a thorough evaluation, which may include a physical examination and possibly laboratory tests, to determine the underlying cause of your symptoms and elevated temperature.

In summary, while your current body temperature readings do not meet the clinical definition of a fever, the accompanying symptoms warrant attention. Monitoring your temperature and symptoms closely, staying hydrated, and resting are essential steps. If you notice any significant changes or if your condition does not improve, do not hesitate to seek medical advice. Your health and well-being are paramount, and a healthcare provider can offer the best guidance tailored to your specific situation.
