PELAKITA.ID – Japanese researchers have introduced a groundbreaking cooling fabric designed not only to reflect heat but to actually lower body temperature.
This innovative material, developed by a team of material scientists, incorporates nano-crystals that deflect infrared radiation and dissipate heat from the body, functioning much like a wearable heat sink.
Unlike conventional sweat-wicking fabrics, this textile doesn’t rely on moisture evaporation. Instead, it uses a passive thermoelectric process to cool the skin, without retaining humidity.
It’s lightweight, breathable, and remarkably efficient — lab trials showed it could reduce body temperature by as much as 3.5°C under direct summer sunlight, all without the need for batteries, fans, or chemical agents.
This silent, maintenance-free system opens the door to numerous applications, including protective gear for construction crews, safer firefighting uniforms, and comfortable clothing for daily use in a warming climate.
It may also prove vital for elderly care and emergency relief during extreme heat events.
Japan is aiming to scale up production of this fabric for use at the upcoming Osaka World Expo, where it will outfit staff working long outdoor shifts.
