👉 Fever math, also known as the "rule of 100," is a simple yet effective method for estimating the time it takes for your body temperature to rise to a fever after exposure to an infection. When you're exposed to a pathogen, your body's immune response triggers inflammation and feverishness. The rule suggests that your body temperature will increase by about 100 degrees Fahrenheit (or 50 degrees Celsius) for every 30 minutes of exposure to the pathogen. For example, if you're exposed to a virus for 2 hours (120 minutes), your fever might start around 102°F (39.4°C) and reach a peak of about 104°F (40°C). From there, it typically takes another 30 minutes to an hour for your temperature to drop back down to normal. This method provides a quick, approximate estimate and can help gauge the severity of an infection or the effectiveness of treatments.
