Human emotions more intense under bright light
People tend to be emotional--both positively and negatively--under bright lights, concludes a study published in the Journal of Consumer Psychology.
Six studies took place under different lighting conditions, and researchers asked participants to rate several things, including spiciness of chicken wing sauce, aggressiveness of a fictional character, feelings about certain words, the attractiveness of someone, and the taste of two juices.
They found that emotions were experienced more intensely under bright lights, including depression. On sunny days, depression-prone people actually became more depressed, said the researchers. In addition, participants wanted spicier wing sauce, felt the fictional character was more aggressive, found the women more attractive and felt better about positive words and worse about negative words. Participants also drank more of the favorable juice and less of the unfavorable juice.
The scientists suggested that emotions may be more intense in bright light may be because light is perceived as heat, which can trigger emotion. By turning down the lights, people may be able to make more rational decisions or settle negotiations in a better way, the researchers concluded.
