Which rectal temperature indicates hyperthermia?

A rectal temperature of 105°F indicates hyperthermia because it exceeds the normal body temperature range, which is typically considered to be around 97°F to 100.4°F. Hyperthermia occurs when the body's temperature regulation fails to dissipate heat effectively, leading to an elevated core temperature. This condition can be caused by various factors, such as excessive environmental heat, strenuous physical activity, or underlying medical issues.

In clinical practice, a rectal temperature of 105°F is significant because it can lead to serious health concerns, including heat stroke or organ dysfunction. Recognizing such high temperatures is crucial for timely intervention and treatment, making it essential in various medical and emergency settings to monitor and respond to hyperthermia effectively.
