Bacteria Growth Prevention Bacteria thrive in warm environments, so hospitals combat this with cold temperatures, which help slow bacterial and viral growth. … Operating rooms are some of the coldest areas in a hospital, usually around 65-69° with a humidity of 70%, to keep the risk of infection at a minimum.

Does cold air kill germs in house?

Air temperature is key for bacteria. In general, cold air kills germs while warm air incubates them.

What temperature kills germs in the house?
