Scientists Develop T-Shirt Fabric That Can Reduce Body Heat And Protect Them From The Harmful Rays Of The Sun

While finding clothes to keep you warm seems relatively easy, there are actually some clothes that can manage to keep you cool. While using light fabrics or certain materials can help keep someone feeling more refreshed than other types of clothes, they’re not as easy to develop as clothes made for warmth.

Unlike buildings or cars, which are often painted on with ultra-white color, or even mirrors or tint that have the ability to reflect the sun’s rays off them, two Chinese scientists discovered a way to keep your skin an impressive 5°C cooler using a normal, everyday t-shirt.

Moreover, the pair of scientists even said that they have found a way to mass produce these shirts, at a fractional cost at that. This would mean that those forced to work outside, or even those that enjoy being on the beach for lengthened periods of time, there’s a way to better deal with the harmful effects of climate change on the body.

How it works is it takes the near-infrared electromagnetic radiation (NIR) from the rays of the sun, which is a component that heats up whatever objects the sun happens to be hitting. These NIRs also cool when they are given off, but when there is water vapor in the air, they are also absorbed within to keep the neighboring air temperature scorching.

The scientists share that the human skin naturally spews a different type of electromagnetic radiation known as mid-infrared. And instead of this radiation being trapped within the water particles, instead, it goes straight out of the atmosphere.

The two scientists, Ma Yaoguang of Zheijang University, and Tao Guangming of Huazhong University of Science and Technology, developed a synthetic fiber blend that has ‘particles of titanium dioxide to reflect the NIR.’ They also have polylactic acid that absorb one’s body heat, which it later on ejects through the shirt as MIR, subsequently cooling the person wearing it.

During testing, one participant wore a special vest made from half white cotton, while the other half was the cooling fabric, while sitting in a lawn chair under the sun for at least an hour. What they saw via thermal imaging was that the portion of the body seen underneath the artificial fabric managed to stay at 5°C, or 9°F, cooler than the other half.

While the report, which was published in Science, shows that there is some doubt over whether the motion of the fabric could actually lessen the cooling effect since any kind of MIR-emitting material has only been tested when it’s kept ‘flat and motionless towards the sun.’ The worry is that a t-shirt that moves or curves over the shoulders and arms of a person could end up having a varied outcome ‘over a vertical midday sun.’

Since the scientists explain that the production and material costs are just a tenth higher than those of regular cotton, manufacturing them should be totally worth the cost. They figure that any type of protective clothing that could make being under the damaging sun less harmful and detrimental is worth a shot. And honestly, we can’t disagree.
