Missing Nights in Wearable Sleep Studies: How to Handle Non-Wear When Participants Forget the Device
One of the most common questions researchers ask when designing a wearable sleep study is deceptively simple: what do you do about the nights a participant forgot to put the device on, or the stretch where a sensor quietly stopped recording? Every real-world deployment produces these gaps. The mistake is treating them as a nuisance […]

One of the most common questions from researchers designing a wearable sleep study is deceptively simple: how many nights of data do I need before my estimate of a participant’s sleep is stable and representative?
How many nights of wearable data do you really need? Learn why 7 nights is enough for habitual means, but 60+ nights are required for sleep variability study.
