The holy month of Ramadan is a sacred time when millions of Muslims around the world embark on a profound spiritual journey of fasting, prayer, and reflection. But it is also a time when many face serious health risks, as going without food or water from sunrise to sunset—often in scorching heat—can lead to dangerous levels of dehydration. Now, scientists at KAUST have found a surprisingly simple way to track the body's water levels during fasting: by measuring how skin interacts with a touchscreen. The study is published in the IEEE Sensors Journal. It is not only useful when fasting. The research team, led by electrical engineer Tareq Al-Naffouri and colleagues at KAUST, showed that the same method applies to athletes, who often experience dehydration due to intense exertion and fluid loss through sweat.
