37C is not really that high
37 C is 99.5 F. That's generally not even considered a "fever" in an adult (which they basically are at their age). That starts about 38C. Here's a table I found:Japanese people go to the doctor an average of 14 times a year, so you could say they are a little health paranoid.
| Temperature (°F) | Classification |
|---|---|
| 97.0 – 99.0°F | Normal range |
| 99.1 – 100.3°F | Elevated / Low-grade fever |
| 100.4°F+ | Fever |
| 103°F+ | High fever |
| 104°F+ | Very high / dangerous |
