In what way can a hydrated atmosphere affect the thermal comfort level in a home?

A hydrated atmosphere, which contains higher levels of humidity, can negatively impact thermal comfort levels in a home. When humidity levels increase, the moisture in the air can make it more difficult for the body to cool itself through the evaporation of sweat. This can lead to a feeling of stickiness and discomfort, as the body's natural cooling mechanisms become less effective.

People often perceive higher humidity as warmer, even if the actual temperature remains unchanged. This perception occurs because the moisture-laden air reduces the effectiveness of sweat evaporation, causing a rise in the body's perceived temperature. As a result, occupants may feel uncomfortable and may need to adjust the indoor climate, typically by using cooling systems or dehumidifiers, to restore a comfortable environment.

While high humidity can increase energy consumption if additional cooling or dehumidification is needed, the main immediate effect on comfort is a decrease. Therefore, the impact of a hydrated atmosphere on thermal comfort is significant and largely negative.
