Your Apple Watch Might Soon Judge Your Sleep Like a Doctor

Apple Watch sleep tracking may soon get a serious upgrade. Thanks to a new UMass Amherst system called BIDSleep, which brings AI smarts to wrist-based data, researchers say the wearable can now get surprisingly close to medical-grade EEG sleep readings. If accuracy keeps improving, the Apple Watch could become a powerful tool for identifying sleep issues long before a hospital visit is needed.
