If the relative humidity of a room is increased, what must happen to the temperature in order to maintain comfort?

When relative humidity increases in a room, it means that the air is holding more moisture. High humidity levels can make the air feel warmer than it actually is because the body's ability to cool itself through the evaporation of sweat is reduced in humid conditions.

To maintain comfort when humidity is high, the temperature should ideally decrease. This reduction in temperature helps balance the discomfort caused by the increased moisture in the air, allowing for a more pleasant indoor environment. As the temperature drops, it can help facilitate the evaporation of sweat and improve overall comfort, making it easier for people to feel cool despite the higher humidity levels.

In contrast, if the temperature were to increase while humidity is already high, it could lead to an uncomfortable environment, as it would further impede the body's natural cooling mechanisms. Consequently, maintaining a comfortable atmosphere in a high-humidity setting typically requires lowering the temperature.
