• Structure: 体温 (たいおん) is a compound noun for the measured temperature of a person’s body.
• Basic usage: 体温を測って記録する makes the post-exercise reading the object measured, while 体温が範囲に戻る makes the value the subject returning to its usual range after a fever.

2. Common pitfalls and similar expressions

• Measurement and return to baseline
  • 体温を測る is the act of obtaining a value, whereas 体温が戻る describes a change in bodily state. Recording a measurement does not by itself establish that it is normal.
