A "normal" body temperature isn't a single number, but rather a range. While 98.6°F (37°C) is often cited as the average, a normal temperature can actually range from 97.5°F (36.4°C) to 98.9°F (37.2°C). This range varies depending on the time of day (lower in the morning, higher in the evening), individual variations, and recent activity.
What constitutes a fever?
Most healthcare providers define a fever as a temperature of 100.4°F (38°C) or higher. However, some sources suggest a temperature of 100.0°F (37.8°C) might also indicate a fever. It's crucial to remember that what constitutes a fever can differ slightly based on the source and individual circumstances. Always consult your healthcare provider if you are concerned about a fever, particularly in children, where high fevers can cause seizures or confusion.
Several sources indicate that a fever is simply a body temperature higher than your usual normal. Therefore, what's considered "normal" varies from person to person and it's important to use this information in conjunction with other symptoms and individual health history.
