It's comfortable to open the air conditioner to 26 degrees, but I watched the weather forecast. At present, the outdoor temperature is 26 degrees. Why is it sultry if you don't turn on the air conditioner? Personally, although the temperature is the same, the humidity, air velocity, solar radiation and ultraviolet radiation are different, so your feelings are different.

First, the smaller the humidity, the hotter it feels, and the air outside is drier than inside;

Second, the slower the wind speed, the hotter it feels, and the stronger the air conditioning (such as the working principle of electric fans);

Third, solar radiation is directly absorbed outdoors, heat is directly absorbed by skin, and it is indirectly absorbed indoors;

Fourth, outdoor ultraviolet radiation is much greater than indoor ultraviolet radiation.
