Does the hotel turn on the air conditioner when sleeping at night?

Don't turn on the air conditioner when sleeping in the hotel at night.

There is no need to ventilate the room when sleeping at night. If you ventilate the room when you sleep at night, especially when you sleep with the window open, it will increase the chance of catching a cold and may cause facial paralysis.

Although indoor ventilation can prevent respiratory tract infection and is good for health, it is generally necessary to get up early every day and ventilate for 15-30 minutes. There is no need for ventilation before going to bed or before going to bed, and excessive ventilation will also have adverse effects on health.

Matters needing attention in hotel check-in

Registration information protects personal privacy. Generally, you must register your relevant information in the lobby before staying in the hotel, especially your ID card and bank card information. Be careful not to be seen by others when registering, because there will be more people in the general hall, so don't be stolen by others.

When choosing a room to stay in, the ground floor is generally not chosen, because the security measures of the ground floor room are relatively insufficient, and outsiders are more likely to break in. At least upstairs, you can largely avoid entering through the window.
