Being touched by a man really gets the ladies hot, new research suggests.Sexy Old Ladies Umina Beach
When physically touched by a male experimenter, women actually did get "hot and bothered" — their skin temperature increased, specifically in the face and chest. Andrews, in the United Kingdom, told LiveScience.
These changes were subconscious in many of the participants. Figuring out how skin temperature changes womab response to stress and other emotional factors could help researchers study arousal non-invasively and develop hands-off lie detectors.
The face heats up when under stress, or when scared, or angry hence the term hot-headed. The researchers wanted to find how other emotions impact facial temperature, so they took heat-showing pictures of two groups of young heterosexual women during a standard interaction with an experimenter, which included touching the arm, palm, toucu and chest using a light probe that they were told measures skin color.
When an experimenter of either gender touched a participant, the participant's average skin temperature toudh about a tenth of a degree Celsius. The effect wasn't as large when considering only touches to the participant's arm or palm, and the skin of the face and chest regions changed the most. The jump was about three times larger when the experimenter was male, the researchers found.
The facial and chest skin of a young female, when touched in those areas by a male experimenter, got about 0. A increase is pretty large for a facial temperature change, the researchers said. Many of the participants were unaware of their skin temperature reaction, when asked about it after the fact.
The rest were consciously unaffected by the interaction," Hahn said. The researchers can't say if the changes are toufh to the naked eye, or if they could be detected with touch. If others can detect these changes, they could serve as social cues that we use to communicate nonverbally.
