Judy Seto, the Lakers’ director of sports performance, wears one. In an interview that took place in February, Seto removed the titanium ring to show the glowing inside where sensors could detect different happenings in her body. “The electronics of this one is similar to a Fitbit but it’s a little bit more accurate,” Seto said. “… I can get it wet. I can have impact on it and it doesn’t catch on anything. This tells me how long did it take for me to fall asleep. It tells me sleep cycles. Light sleep, deep sleep, REM sleep. How much did I get. Did I stay asleep or did I toss and turn at night? Gives me feedback of, ‘Hmm saw that you went to bed a little late or you kept on waking up at night. Is something bothering you?’ Your body temperature’s elevated, are you feeling well? Maybe you’re getting a little under the weather.”
