Wearable hydration monitor could help prevent heatstroke, scientists say

A new wearable sensor could help people avoid the dangers of dehydration by alerting them when their bodies need more water Developed by researchers at the University of Texas the non-invasive device continuously measures hydration levels in real time and wirelessly transmits the records to a smartphone according to an SWNS statement Dehydration is a silent threat that affects millions of people every day stated Professor Nanshu Lu of the University of Texas at Austin who led the examination CLINT EASTWOOD'S LONGTIME SECRETS OF GOOD STRENGTH AND LONGEVITY REVEALED Our wearable sensor provides a simple effective way to monitor hydration levels in real time empowering individuals to take proactive moves to stay healthy and perform at their best she added per SWNS The sensor uses a method called bioimpedance which sends a small safe electrical current through the body via strategically placed electrodes The current's flow depends on how hydrated the tissues are hydrated tissue allows the current to pass easily while dehydrated tissue resists the flow according to SWNS Arm bioimpedance is not only sensitive to hydration changes but also aligns closely with whole-body hydration measurements announced survey co-author Dr Matija Jankovic a post-doctoral researcher in Professor Lu s lab This means the sensor can be a reliable surrogate for tracking hydration levels even during everyday pursuits like walking working or exercising Jankovic added To validate the device the research company conducted multiple experiments including a diuretic-induced dehydration review and a -hour real-life trial Participants were given medication to promote fluid loss Their hydration levels were monitored via the wearable and compared to urine samples CLICK HERE TO SIGN UP FOR OUR HEALTHCARE NEWSLETTERThe device established a strong correlation between changes in arm bioimpedance and total body water loss SWNS stated The findings were published in the Proceedings of the National Academy of Sciences The new sensor could offer an accessible and wearable alternative to traditional hydration tracking methods such as urine or blood analysis which are invasive time-consuming and impractical the researchers noted Hydration is known to be essential for regulating body temperature maintaining organ function and supporting numerous other vital processes Even mild dehydration can impair concentration and performance while severe dehydration may lead to serious soundness problems like heatstroke kidney stones and cardiovascular issues according to experts Beyond everyday use the researchers believe the mechanism could benefit patients with chronic dehydration kidney sickness or heart conditions Athletes too could use the wearable to stay safe and perform optimally especially in hot weather While the current model tracks relative hydration changes Professor Lu noted the band aims to develop reference evidence for absolute hydration levels They are also exploring more advanced wearable formats like breathable electronic tattoos or sweat-absorbing patches to enhance comfort during long-term use For more Healthcare articles visit www foxnews com wellbeing This is just the beginning Professor Lu explained per the SWNS summary Our goal is to make simple hydration monitoring accessible to everyone
