Did you know your watch can spot dehydration?

Transcript

Imagine your watch not only telling time but also keeping an eye on your hydration. Modern wearables use sensors that measure the electrical conductance of your skin, a method known as galvanic skin response. When you are well hydrated, your skin has more water and conducts electricity better. In contrast, when you are dehydrated, the skin becomes less conductive due to reduced water levels. These devices also monitor subtle changes in your body temperature, which can provide further clues about your hydration status. Together, these advanced measurements help predict when you might be becoming dehydrated, allowing you to take action before health issues arise.
