Humans do Blush in the Dark; Scientists from Germany Reveal

It was long known that blushing is one of the common and most fascinating expressions that humans experience but what actually makes this happen was still a mystery. To reveal the fact a team of researchers from the Germany's University of Erfurt and the Dutch Academy of 'Pataphysics in Amsterdam with the help of heat-sensitive cameras, revealed that humans mostly blush in the dark. This report has been published in the Telegraph UK reports.

The instruments that have been used for this study are not new. These existed around for several years, but have never been used before.

During the study, a 31-year-old woman was made seated in a blacked-out room. The room had a thermogenic camera using which the team was able to record her face expressions and its temeprature. Denise Wächter and Wolter Seuntjens were also a part of this team.

Once the woman adapted the room's temperature, the team measured her pre-blush measurements and then asked her to describe an embarrassing incident that she had experienced in her life. When the woman started, she was blushing, and at that time, they took a second measurement of her blush.

As a result, they revealed that the amount of heat in her face was higher than before.

The researchers reported in the Annals of Improbable Research: "By showing that people can blush in the dark we have finally solved this age-old problem".
