How to use the air conditioner in the hotel?

1- Turn on the air conditioner when you leave the room and turn off the air conditioner when you come back from the trip. The room is very cool.

2- Adjust the temperature before going to bed, and don't turn on the air conditioner when sleeping.

3- The difference between indoor temperature and outdoor temperature should not be too big, generally about 5℃. Of course, personal habits and requirements should also be properly considered.

4- at any time, avoid cold air blowing directly on your body.

5- Don't blow cold air when you come back from a sweaty trip or just after taking a shower, or you will catch a cold easily.
