It's a little cold recently. Will turning on the air conditioner for one day and one night have an effect?

Obviously, using air conditioner for a long time, closing doors and windows when you rest, indoor carbon dioxide exceeds the standard, which leads to depression and lack of oxygen in the brain. At this time, people must not rest well. In this case, it is necessary to open the window to let the indoor air circulate, but it will definitely affect your rest, because the noise outside will also affect the energy consumption of the air conditioner.
