Did you guess that there is a reason hospitals are so cold? The hospitals are required to keep the cooling set honestly low for safety complications, however the main reason is the spread of bacteria & germs, then mold prefers warm, wet places… With the AC on, that is no longer a problem, but a cooling plan naturally dries out the air & also keeps it colder.
Mold, mildew & fungi have a harder time forming & breeding in honestly chilly conditions.
Also, the cooling plan circulates the air around a space. The odors, dust & hair that is in the air quality is being moved all around, but it is better for a patient to breathe in, then hospitals do go one step further & have ultraviolet lights installed in the AC equipment. As the air is cycling around, the UV lights are purifying it. The air is typically fresh & wipe for a person to breathe in. Another reason for the heavy cooling is sweat prevention… Not only would it be gross for a nurse to toil around sweat, but not as safe. The sweat could contaminate a room or make an operating process messy. The cooling plan has the patient cut out in goosebumps rather than drip. Also, the AC is for the nurse too. The kicker is that hospital operating tools emit heat… So the AC has to counteract the tools, movement & stressful situation by adding a bunch of chilly air in the space. So while no one likes freezing to death on a check up, there is a superb reason for it.
