«While the ability to sense the moisture of the skin is important for the behavioral and autonomic adaptations, humans are no specific skin receptors to determine the moisture content. Since a hypothesis was that we "learn" feel humidity based on the earlier situations where our skin is in contact with a moist surface. However, the individual role of thermal and tactile signals, and how they interact in the central nervous system when in contact with moisture, are not yet fully understood.
During the quantitative sensory testing, we found that people perceive the warm-wet and wet-neutral subjects as less wet compared to cold-wet, but the moisture content was the same everywhere. Furthermore, when the skin temperature and tactile sensitivity was significantly reduced by suppressing the activity of the corresponding nerve-afferents, the perception of the subjects significantly decreased humidity. The experimental results provide evidence of the existence of a specific model of information processing, which reinforces the nervous representation of a typical wet incentives. Data collected during the experiment will help to better understand how people feel warm, neutral and cool moisture of the skin ».
