The invention discloses an air conditioner adjusting method for dynamically maintaining the comfortable degree of a human body in a heating mode. The method comprises the following steps: S1, presetting a mapping relationship between a real-time environment temperature and a target comfortable degree, wherein the real-time environment temperature comprises a real-time outdoor environment temperature and a real-time indoor environment temperature, and the target comfortable degree comprises a target indoor environment temperature, a target indoor humidity, a target indoor wind speed, a target indoor oxygen content and a target noise decibel; and S2, detecting the real-time environment temperature, the real-time indoor humidity, the real-time indoor wind speed, the real-time indoor oxygen content and the real-time indoor noise decibel, and obtaining the target comfortable degree according to the preset mapping relationship and adjusting an air conditioner until the target comfortable degree is achieved. After the air conditioner is switched on, the environment temperature and the current indoor comfortable degree are detected in real time, and then the current indoor comfortable degree is adjusted to be the target comfortable degree, and the temperature is not needed to be set manually, so that circumstances such as overcooling, overheating and air-condition disease are avoided.
