Sleep Devices & Products
From sleep trackers and CPAP machines to white noise devices and weighted blankets — an evidence-based guide to the technology and products that can genuinely improve your sleep.
A Note on Consumer Sleep Devices
Consumer sleep technology has advanced rapidly, but it's important to understand its limitations. Wearable sleep trackers and smartphone apps are not medical devices and cannot diagnose sleep disorders. Their accuracy for sleep stage identification is significantly lower than clinical polysomnography (PSG). That said, many products in this category provide genuinely useful data for tracking trends and patterns over time, which can inform conversations with healthcare providers and guide behavior changes.
