Some decisions are so difficult that you can mull them over from every conceivable angle and there is still no obvious answer.

But if you need to make an enlightened decision, dimming the lights could help. Scientists claim that turning down the lights reduces emotional intensity, allowing you to keep a clear head when making tough choices.

A new study led by the University of Toronto Scarborough has found that both positive and negative human emotions are felt more intensely in bright light.

Alison Jing Xu, an assistant professor of management at the university, and Aparna Labroo of Northwestern University conducted a series of studies to examine the unusual paradox of lighting and human emotion.

While other studies have shown that people can be more optimistic about the stock market on sunny days and that gloomy days can result in seasonal affective disorder, Xu said: “We found that on sunny days depression-prone people actually become more depressed.”

The duo asked experiment participants to rate a wide range of things, such as the spiciness of chicken-wing sauce, the aggressiveness of a fictional character, how attractive someone was and the taste of two juices, under different lighting conditions.

They found emotions run higher in bright light, so sauce tasted hotter, characters felt more aggressive and people looked more attractive. – Daily Mail
