She explains how Firstbeat’s professional-grade wearable tech helps individuals and organisations understand stress patterns, sleep quality, and the importance of personalised recovery. Backed by large-scale data trends, Tina offers practical insight into what modern life is doing to our bodies and what we can do to counterbalance it.Check out Firstbeat at https://www.firstbeat.com
