Smartwatches and GPS devices show promise for tracking environmental impacts on health in real time

As climate change drives more frequent extreme heat and worsening air pollution, researchers are seeking better ways to understand how these exposures affect health in real time. A new pilot study led by researchers at The City University of New York demonstrates the feasibility of combining wearable devices, smartphone location data, and real-time surveys to capture individuals' environmental exposures and their immediate physical and emotional effects.
