Lamp tracks sleep without wearables

A sleep tracker usually works by watching a signal your body leaks all night, like motion from your wrist or changes in your pulse, and then guessing whether you are awake, in light sleep, or in deep sleep. The new twist is a bedside lamp called the Sleepal AI Lamp that says it can make those guesses from your nightstand instead of from your skin. (youtube.com) (sleepal.ai) The lamp’s main sensing trick is millimeter-wave radar, which is a radio-based way to notice tiny movements the way a bat notices a room without touching anything. Sleepal says that radar lets the lamp pick up breathing rhythm, body movement, and presence from beside the bed without a watch, ring, or strap. (homekitnews.com) (gadgetsandwearables.com) Once a device can see those small movements, it can turn them into a sleep report by matching patterns, like hearing footsteps upstairs and inferring who is awake. Sleepal says its app shows sleep score, sleep efficiency, breathing score, sleep stages, heart rate, respiration rate, heart rate variability, noise, temperature, humidity, illuminance, sleep regularity, and duration. (homekitnews.com) The lamp is not just measuring the room after the fact. Sleepal says it uses the data in real time to dim into warmer light at night, reduce output after it detects sleep, add low-level light if it senses wakefulness, and brighten gradually in the morning as a wake-up cue. (homekitnews.com) That makes the product different from a plain sleep tracker in the same way a thermostat differs from a thermometer. A thermometer only reports the temperature, while a thermostat changes the room, and Sleepal is pitching the lamp as both the sensor and the thing that changes your sleep environment. (homekitnews.com) (sleepal.ai) The April 9 YouTube review that pushed this product into wider view came from smart-home creator Shane Whatley, who said he had used the lamp for several weeks and that it replaced his Apple Watch for sleep tracking and even his phone at night. In the video description, he lists contactless sleep tracking, adaptive wake-up lighting, posture insights, white noise, environmental sensing, and possible future Apple Health integration as the key features. (youtube.com) Sleepal says the device processes data locally and includes a physical privacy button, which matters because a bedside sensor is sitting in one of the most private rooms in a home. The company also says the system was validated with more than 2,000 clinical datasets and claims 99 percent heart-rate correlation, 99 percent breathing-rate accuracy, 95 percent snoring detection accuracy, and 91 percent sleep-position accuracy. (sleepal.ai) Those numbers should be read like carmaker mileage claims, which are useful for comparison but not the same as everyday driving. The American Academy of Sleep Medicine says consumer sleep technology has potential uses, but it also says these products have limitations and should not be treated as clinical truth in the way a formal sleep study is. (aasm.org) That gap matters most when companies move from “tracking” to “screening.” The Food and Drug Administration’s clearance for Apple’s sleep-apnea notification feature says it is meant to detect signs of moderate to severe obstructive sleep apnea in adults, but it is not intended to replace traditional diagnosis or treatment by a clinician.

It is that sleep tech is moving away from gadgets you remember to wear and toward furniture that watches passively, the way a smoke detector watches the ceiling. If that shift works, the winning products may be the ones that ask for the least effort, reveal just enough about your body to be useful, and keep the raw data inside the room.
