What does it mean to turn on the air conditioner in the hotel?

Hotel air conditioning, literally, air conditioning.

Turning on the air conditioner will make the indoor air dry, plus the air is not circulating, which is easy to make people stuffy nose, dry throat and sneeze. In addition, the body temperature will drop when sleeping. If you turn on the air conditioner all night, it will easily cause respiratory discomfort and even cause a cold.

Air conditioning instructions

What is the appropriate temperature for air conditioning? I think the temperature difference between indoor and outdoor is almost 6 or 7℃. If the temperature difference between indoor and outdoor is too large, it is easy to make people's resistance drop between sudden cooling and sudden heating, causing air-conditioning diseases similar to cold symptoms. Scientific research has found that the most comfortable temperature for human body in summer and autumn is about 26℃.

As we all know, the proportion of cold air is larger than that of hot air, so when blowing air conditioning, if you don't choose the swing mode, you'd better put the fan blades up, that is, send the cold air up. In this way, the air can circulate, the overall environment will become cool, and at the same time, cold air will be prevented from blowing directly on you.
