Have you ever imagined that your simple T-shirt could cool you down by up to 5℃ on these hot summer days? Thanks to a recent discovery, the possibility is getting closer. An amazing invention can help those who want to feel comfortable and fresh in the outdoors on extremely hot days.

Its inventors, engineers Ma Yaoguang and Tao Guangming, made a great discovery. They designed a special textile (纺织物) that can absorb body heat and send out its energy into space as MIR (中红外辐射). This textile cools both the objects and their surroundings. This means that you are actually wearing a shirt that works like a mirror.

Scientists at Stanford University in 2017 had already managed to cool the wearer by 3℃, but this was not enough. So researchers still need to test the new textile to see how effectively it works while the wearers are taking outdoor activities. They also need to examine how well it works when T-shirts are not in close contact with the skin.

Ma and Tao are now looking for producers that are interested in using their textile. They believe that the new material will increase costs by just 10 percent. "We can make it with mass production (大批量生产), which means everybody can get a T-shirt and the cost is basically the same as their old ones," Ma said.

So if you are an athlete or simply someone that has to deal with the extremely high temperatures, be patient because your days of feeling hot may come to an end soon!
