Your Apple Watch might be the key to addressing nightmare-related sleep issues. The FDA has approved the sale of NightWare, an Apple Watch app (with a corresponding iPhone element) that helps treat nightmares stemming from disorders like PTSD. The system uses smartwatch motion and heart rate data to detect when you’re having a nightmare and vibrate the wristwear in response, arousing (but not waking) you to interrupt bad dreams and maintain sleep.NightWare is prescription-only, and its eponymous company stressed that this wasn’t a standalone treatment. It’s part of a larger strategy that includes medication. It also warned against trying the Apple Watch therapy if you “act out” during sleep.
