Scientists at Stanford University have invented a fabric that is able to cool the person’s body by 2 degrees Celsius and to reflect the sun’s rays, allowing you to leave the thermal radiation. It is reported by The Telegraph.

at normal temperature of the human body, radiates heat in the mid-infrared range which partially overlaps with a part of the visible light spectrum. Any tissue that blocks the visible light, and also picks up body heat.
The material created by the American physicists characterized in that the heat does not accumulate and block the penetration of heat and light from the outside. Scientists say that this shirt is cool even in rooms without air conditioning. It follows that the invention has yet another advantage – economic. With this dress, the electricity will be consumed less.
NanoPE, so scientists named material is a thin film with tiny holes – hundreds of times smaller than a human hair. They passed the infrared light but block that is visible to the human eye.
The fabric allows sweat to evaporate. If the cotton passes only 1.5 percent of the infrared waves, nanoPE permeability – 96 percent. According to the physicists, in clothes from the new material a person is 2 degrees cooler than in the cotton.
Now that of a material such clothes were not only functional, but also attractive, scientists have been experimenting with different colors. the researchers also tested the fabric on other sites -. tents, buildings and vehicles
