我觉得是24-27摄氏度（75-80F）。
低则略冷，高则太热。（在室内只穿内衣的状态）

The most comfortable room temperature for humans typically falls between 68°F to 72°F (20°C to 22°C). However, comfort can vary based on factors like humidity, personal preference, and activity levels. Generally, a slightly cooler temperature is recommended for sleeping, around 60°F to 67°F (15.5°C to 19.5°C).
