Could a few feet of the cold stuff really have such a fundamental effect on beliefs and behavior? Absolutely, according to recent studies on how temperature influences us at an unconscious level. Researchers affiliated with the Center for Decision Sciences at Columbia Business School measured the public's changing attitudes about climate change

Those who felt that the current day was warmer than usual for the time of year were more likely to believe in and worry about global warming than those who thought it was cooler outside. They were also more likely to donate the money they earned from taking the survey to a charity that did work on climate change.

Physical warmth activates circuits in the brain associated with feelings of psychological warmth. The insular cortex, or insula, plays a critical role in this crossover between the outside world and our experience of it. This peach-sized region helps us to perceive whether a sensation is hot or cold, pleasurable or painful. It is activated when we crave chocolate, fall in love or get disgusted. The insula also guides us on social matters: whether to trust or feel guilty, to empathize or be embarrassed. People who meditate, according to some studies, have a thicker insula.

As it turns out, the insula's poetic merging of the physical and emotional helps to explain much of our unconscious behavior. People who are socially rejected—given the cold shoulder—get chills and crave warm food such as soup.

Warm springtime conditions are related to a better mood and expanded memory, but both take a plunge in the summer heat. Extreme temperatures make people hostile and aggressive, and violent crimes occur more often in the hotter months. Drivers honk more in heat waves. When you're hot and tired, you're more likely to interpret another person's neutral expression negatively.

our perception of reality still relies on sensory experience. Though we may wish for it to be otherwise, our minds cannot be separated from our bodies. And our bodies depend on the environment—what we encounter here on planet Earth
