Related Notes:Many people use air conditioners in the summer to keep their homes as constant or quasi-constant as possible. However, medical meteorologists have found through experiments that constantly adjusting the temperature of the room can make people's physiological body temperature regulation mechanism in a "tense state", so as to gradually adapt to the greater changes in temperature and improve people's self-protection ability.

Correct approach: The temperature of the whole room should be constantly changing, but the amplitude should be controlled between 3 and 5.
