The Japanese Wikipedia states that the mean human body temperature is 36.0 °C (here, row "ヒト").
The statement is referenced by data from the Japanese government.
Actually all of my Japanese friends think the same.
A body temperature of 37.5 °C is considered serious illness in Japan, justifying absence from work.
Most other countries' sources cite 37.0 °C as the mean human body temperature.
Is there a biological explanation to this apparent discrepancy?
