Popular Mechanics asks if you should spend a lot of money on gadgets to help you sleep better.
Bedside trackers sit on your nightstand and use radar to track movements as fine as individual breaths. I asked Hawley Montgomery-Downs, a professor at West Virginia University who tests sleep trackers (and who has a fantastic name), if that actually works. She said one consumer device, the ResMed S+, has shown promise in clinical tests. The new SleepScore Max uses S+ technology and adds software from a sleep expert formerly of Apple’s Health team. It’s beautifully simple: Rather than confusing charts, it offers a numerical rating of overall sleep quality—and coaching to help raise it.
