This is an automatically translated article.

Previously there was a saying that hands are cold, heart is warm, but in fact, through researches by scientists, the opposite results are shown. Because when we are exposed to warm things, it can stimulate the formation of hormones and create a more sympathetic feeling.

1. What is a warm hand, a warm heart?

Through many studies it has been found that very subtle signals from our environment can significantly influence our behaviors and emotions. There is evidence that throughout our evolution, the part of the brain responsible for processing human warmth is closely related to the part of the brain responsible for physical warmth. Thus, sensory warmth and physical warmth interact.
Lawrence Williams, PhD, assistant professor at the University of Colorado at Boulder, and John A. Bargh, PhD, professor of psychology at Yale University, conducted two studies on college students to evaluate How temperature affects emotions.
The first study was conducted as follows:
First 41 university students were selected with an average age of 18.5 years. An experimenter met each participant in the lobby of the building where the trial was being conducted. In the elevator on the way up, the experimenter asked the participant to hold his or her cup of coffee. Participants did not know the cup of coffee was part of the experiment. Half of the participants were asked to hold a warm cup of coffee and half were asked to hold a cup of iced coffee. Next, when entering the test room, the test participants were given some information about an unknown person and described with words such as smart, ingenious, industrious, practical, and cautious. After receiving the information, the test participants were asked to rate the person's personality with a questionnaire. Participants holding a warm cup of coffee were much more likely to be sympathetic to the information provided than those holding an iced coffee.

In the 2nd study the following was done:
The researcher recruited 53 participants and these participants were asked to hold a hot or cold therapy pad. Participants claimed that they played a role in evaluating the therapeutic product. After testing by holding the therapy pad, the researchers were given an offer to choose a reward for themselves or for a friend or loved one. It was found in this study that the majority of people holding warm therapy pads would choose a gift for their loved one or themselves rather than for themselves. For people holding cold therapy pads, the opposite is true. Through two studies, it was found that physical temperature can affect our behavior and emotions with things around us, like liking someone we don't even know. When our hands are in contact with warm things, creating a feeling of physical warmth also makes us perceive others as warmer and also makes ourselves feel warm, generous, and welcoming. more reliable. So the saying warm hands, warm heart also has a scientific basis. No matter what your personality is, the initial sympathy of others with you is also very important. Apply in daily life if you want to create sympathy for someone, then offer them a hot drink.
