Washington (SmartAboutHealth) - A new study has found a direct link between warm hands, and having emotionally warm thoughts about someone.

The study was led by Lawrence Williams of the University of Colorado.

The study was carried out with a group of college students in a controlled experiment.

The student volunteers were tested at Yale University’s psychology building.

They gave half of the students a cut of hot coffee, and the other half an iced coffee.

They held the cups of coffee for just a few seconds while riding an elevator.

The coffee was given to them by a woman who was taking them up in an elevator.

During the elevator ride, they were handed the cup of coffee in a discrete way for just a couple of seconds.

Once on the fourth floor, the students had to then fill out a questionnaire, which included evaluating the personality of the woman.

The students who held the hot coffee stated that the woman was more generous, social, and happier.

This compared directly to the students who held the iced coffee.

The study found a direct link between having warm hands, and feeling emotionally warm about someone else.

This was backed up by another similar experiment with the same result.

The study was published in the journal Science.
