Smartwatch algorithm could predict asthma attacks a week in advance

Asthma affects 1-in-7 children and 1-in-8 adults in New Zealand, with Māori and Pacific populations experiencing 2-3 times higher hospitalization rates and excessive steroid exposure increasing risks of diabetes, stroke, and cardiovascular disease.

For half a century, asthma care has followed a familiar rhythm: wait for the crisis, then respond. Researchers at the University of Auckland are now challenging that logic, developing a smartwatch system capable of detecting the physiological signs of an impending attack up to seven days before it arrives — offering, for the first time, a genuine window for prevention. The work carries particular weight in a country where Māori and Pacific communities bear a disproportionate share of asthma's harm, and where the standard treatments themselves carry serious long-term risks.
