Your Apple Watch may be the key to addressing sleep problems related to nightmares. The FDA has approved the sale of NightWare, an Apple Watch app (with its respective iPhone element) that helps treat nightmares stemming from disorders like PTSD. The system uses the smartwatch’s heart rate and movement data to detect when you have a nightmare and vibrates your wristband in response, awakening (but not waking) you to interrupt bad dreams and uniquely maintain sleep.
NightWare is only prescribed by prescription and its company of the same name insists that this is not an independent treatment. That̵7;s part of a larger strategy to include drugs. It also warns against trying Apple Watch therapy if you “act” while you sleep.
