Human emotion is also dominated by the light

Two researchers Aparna Labroo and Xu Jing, Alison has conducted a series of studies to examine the extraordinary paradox of light and human feelings. Soothing light reduces the intensity of emotion, allowing you to have "cold heads" to make the hard choices.

The previous research pointed out, people feel more optimistic on sunny days and emotional disorders or in those gloomy days. But Professor Xu said: "we found that on sunny days, people are also vulnerable to depression."

To get to this, experts conducted a survey of volunteers and asked them to rate a series of things, the sweetness of the sauce, the flavor of the two types of juice or hot anger before each measurement situations ... in two different light conditions.

The experts found, emotions of the volunteers usually higher increase with light intensity is stronger, so they will feel darker sauce, a character in the film more appealing ...

Professor Xu believes, lighting effects can impact on the emotional level, causing many different emotional state. She added: "excessive amount of light will affect the reaction as well as our emotions are dominant. So, with just the right light intensity, gentle will help people take more rational decisions, as well as resolve the negotiations easier. "

In addition to the light also helps people relieve pain. The scientists of the Department of Bio-X at the University of Stanford (USA) have used gene therapy to impact the species of mouse, so you can use the light projected onto the base of the mouse changes the sensitivity of the pain.

This application in neural modulation technique called optogenetics. Start by inserting the light sensitive protein called opsin in the nerves of mice. The researchers found that when exposed to the levels of different colors and then the mouse is very sensitive to the pain increases or decreases.

Scientists believe that this research will help to understand more deeply on how to endure the pain of the individual and will eventually use of light to treat for humans, especially those patients with debilitating and chronic pain patients.

Gizmag magazine quoted Professor Linda Porter of Stanford University said, this approach shows great potential to help millions of patients with persistent pain due to nerve damage.=
