What is the normal skin temperature?

Under normal circumstances, skin temperature ranges from 36°C to 37.5°C, though it may vary due to multiple factors. If you experience any discomfort, seek medical attention promptly and follow your physician’s guidance for appropriate treatment. A detailed analysis follows:

When at rest, a person’s normal skin temperature typically falls between 36°C and 37.5°C. However, this range is not absolute; skin temperature may vary depending on time of day, gender, anatomical site, and physiological state. Over the course of a day, normal skin temperature fluctuates: it reaches its lowest point between 2:00 and 5:00 a.m., and peaks between 5:00 and 7:00 p.m. Nevertheless, this diurnal variation generally remains under 0.8°C. Additionally, skin temperature differs across body regions. For instance, the skin on the fingers, forehead, and oral mucosa tends to be relatively cooler, whereas the palms, chest, and axillae tend to be relatively warmer.

If skin temperature exceeds 37.8°C, it may indicate low-grade fever; temperatures above 38.4°C signify high-grade fever, requiring prompt cooling measures.
