Yes, that's what I know. Another reason why you place the air conditioning unit "away from people". The skin and muscles "will get sick" if exposed to sudden change in humidity. Some with sensitive skins can attest to this, like formation of "flakes" around the lips and itchiness to joints accompanied by redness.

It is generally recommended to set the thermostat with a 5 degree difference from the ambient temperature, comfortable to most people staying inside the room all the time.

However, most of us are known to be stubborn, just like me, and so we go against the recommendations​ of the experts.
