How many degrees is it appropriate to turn on the air conditioner in winter?

It is suggested to turn on the air conditioner at around-1 degree in winter, because we usually wear thick clothes in winter. Although the weather is very cold, we wear thick clothes and keep warm indoors.

Then, it can not only save resources, but also be more conducive to environmental protection. It can also be preheated when needed and save unnecessary waste when not needed.

Finally, not turning on the air conditioner will make the body feel dependent and unable to adapt to colder weather. If it is opened unnecessarily, it can increase the body's resistance, and the advantages outweigh the disadvantages.

Therefore, it is recommended to turn on air conditioning or heating at around-0/degree in winter.
