With gadgets to mentor your fitness, the latest tech will make sure you're drinking enough water
Our bodies are 70% water. When we're well hydrated we think more clearly, we sleep more deeply and our skin glows. And, now we're all well used to being prompted to keep moving by counting our steps, and encouraged to exercise portion control by counting our calories, the latest element of our wellbeing to track is our water intake.
Coming next in fitness wearables is the world's first hydration monitor. US company LVL has created a fitness tracker worn on your wrist that doesn't just check your heart rate, steps, calories burned and sleep; it also tells you exactly how much water you need to drink, using infrared light to measure the water levels in your body and your sweat rates.
It even tells you how much you can expect your workout performance or sleep quality to improve if you follow its instructions.
LVL founder and CEO Dustin Freckleton says he was aiming to create a wearable that focused on people's actions rather than just analysing data.
He was inspired to tackle hydration when he suffered a stroke, caused by being dehydrated, as a medical student.
The start-up's patented red-light technology is shone into the body from the bracelet, and the way the wavelengths are absorbed creates a spectrographic picture of the body's water content at that moment. Shipping is planned for next August and trackers will cost $199.99 (£164).
Until then, there are hydration apps such as Waterlogged and iDrated Water to keep a log of your H2O. And the latest Apple Watch has an app called WaterMinder, which encourages you to record every time you have a glass of water and reminds you if you're not on course to reach your daily target.
It might seem as if all this data-monitoring is counter-intuitive to the mindful approach we're all supposed to be making towards our health, but it actually plays into the concept of staying present and being aware of your body.
The health service recommends we drink six to eight cups of water every day, so be mindful of your thirst, savour every sip and enjoy that virtual pat on the back from your phone.
