There is no summer that passes without hearing the classic mantra from all national news: you drink a lot. Be hydrated It is essential to keep body temperature low and ensure the correct functioning of the organs.
Now a wearable device (in English Wearable) developed by researchers from the University of Texas in Austin promises to help us constantly monitor the hydration levels of our body in a non -invasive way. The details are published on PNAS.
The importance of water. Our body is made for about 60-70% of water (percentage that rises to 75% in children). Water is essential because it transports nutrients, regulates the temperature and makes the joints and delicate organs such as the brain and eyes correctly function.
Just lose 0.5% of liquids to be thirsty, reaching 7% you start having hallucinations And with 10% less you enter coma. This is why it is essential to monitor the hydration levels of our body, especially when it is hot or when we carry out physical activity.
Electrical flow. The device developed by the researchers uses the bioimpertencea technique that involves the passage of a weak electric current through the body, to monitor the body’s hydration levels. The way electricity flows depends on the quantity of water present in the fabrics: if hydrated electricity flows easily, if dehydrated it passes with greater difficulty.
To test the operation of the appliance, the researchers conducted several experiments, comparing the sensor results with those of a urine sample. “The sensor can be a reliable alternative to monitor hydration levels, even during daily activities such as walking, working or exercising,” says Matija Jankovic, one of the authors.
Advantages and future developments. Compared to traditional methods, such as urine or blood tests, this is not invasive, it is quick and collects data in real time. Other similar devices on the market are more bulky and require the user to remain stationary during monitoring, limiting their use. In the future it would be interesting to explore new design, such as wearable or wearable tattoos capable of absorbing sweat, to improve comfort and performance during prolonged use.
