FDA-approved Apple Watch NightWare app treats PTSD-linked nightmares

An app designed for Apple Watch has received approval from the Food and Drug Administration (FDA) for an effective treatment for nightmares caused by post-traumatic stress disorder (PTSD). Called NightWare, the application is now marketed as an aid for the'temporary reduction of sleep disturbances related to nightmares in adults.' The app uses Apple Watch sensors to monitor body movement and sleep and when it detects the user is experiencing a nightmare, the device will vibrate to disturb their sleep. NightWare is currently only available with a prescription and the company stresses it is not a standalone treatment for PTSD. Approximately eight million Americans suffer from PTSD and up to 96 percent of them have nightmares as a result.
