This device uses Apple Watch to address nightmare disorder

The US Food and Drug Administration (FDA) has permitted marketing of a new device that uses Apple Watch to reduce sleep disturbance related to nightmares. The device targets adults 22 years or older who suffer from nightmare disorder or have nightmares from post-traumatic stress disorder (PTSD), the FDA said on Friday.

It provides gentle vibration through touch based on an analysis of heart rate and motion during sleep.

The device, called Nightware, is a digital therapeutic that uses an Apple Watch and an Apple iPhone that are configured and logged into a software application and the Nightware server.
