**San Francisco, CA** – While smartwatches boast life-saving features like fall detection and heart rate monitoring, hydration tracking remains a neglected area, despite its crucial role in preventing heat exhaustion and dehydration, especially during strenuous activities.
The recent tragic death of a runner during a half-marathon in scorching heat has highlighted the need for improved hydration tracking on smartwatches. Experts warn that athletes, especially those in hot weather, must stay hydrated, and smartwatches are uniquely positioned to assist in this critical area.
While some brands like Samsung and Garmin offer basic hydration tracking features, they are often limited to manual logging or generic reminders, lacking the context-sensitive approach required for personalized hydration recommendations.
“It’s past time for fitness brands to prioritize hydration tracking,” says Michael, Android Central’s wearable expert. “Smartwatches have the potential to estimate sweat loss based on activity and provide personalized reminders to rehydrate throughout the day, especially during workouts.”
Samsung, for example, utilizes a combination of heart rate, body data, and ambient temperature to estimate sweat loss. While this is a step in the right direction, experts advocate for more advanced solutions like direct sweat measurement.
“Ideally, a smartwatch would continuously monitor sweat levels and provide real-time recommendations, adjusting hydration goals based on individual needs and environmental factors,” adds Michael.
The future of hydration tracking lies in incorporating real-time sweat measurements, leveraging existing technology like the cEDA sensor found in the Pixel Watch 3, or developing new sensors like the ones Apple has patented.
By combining advanced sensor data with algorithms that consider individual factors like body size, age, and activity level, smartwatches could provide users with vital hydration alerts during workouts and beyond, helping them stay safe and perform at their best.
“Smartwatches have the potential to be more than just fitness trackers,” says Michael. “They can be essential tools for promoting health and safety, and hydration tracking is an area that needs urgent attention.”
