A recent study has suggested that warm hands lead to warm thoughts about the person.

The study headed by Lawrence Williams of the University of Colorado studied a group of college students in a controlled experiment.

The volunteers were tested at the psychology building of Yale University of Colarado.

During an elevator ride a woman handed over cups of coffee to the volunteers. Half the volunteers were given hot cup of coffee whereas the other half were given iced coffee. They held the cups while riding an elevator which means just for a few seconds.

Thereafter the students were asked to fill up a questionnaire.

A surprising revelation was made by the volunteers. The students who had been given hot coffee described the woman as more generous, happier and more social as compared to the ones who has been served cold coffee.

In a second study 53 different students were made hold one of those heat or ice pads sold in drugstores for pain as attesting campaign for a product. Thereafter  they were asked to choose between -  An ice-cream coupon or bottled drink for themselves, or one for a friend.

Students who held the hot pad were more likely to choose a reward for a friend, while those who held the ice pad were more likely to choose a reward for themselves.

Physical and psychological concepts "are much more closely aligned in the mind than we have previously appreciated," said Williams, now at the University of Colorado.
