Season 9, Episode 7 w Dr Hannah Scott: 11 million nights of sleep data, what can it tell us?

In this episode, I am joined by Dr Hannah Scott. We specifically discuss her recent work, “Are we getting enough sleep? Frequent irregular sleep was found in an analysis of over 11 million nights of objective in-home sleep data. In this study, data were analyzed from registered users of the Withings under-mattress Sleep Analyzer (predominantly located in Europe and North America) who had ≥28 nights of sleep recordings, averaging ≥4 per week. Sleep durations (the average and standard deviation) were assessed across a ∼9-month period. The sample consisted of 67,254 adults (52,523 males, 14,731 females; aged mean ± SD 50 ± 12 years). About 30% of adults demonstrated an average sleep duration outside the recommended 7-9 h/night. Even in participants with an average sleep duration within 7-9 hours, about 40% of nights were outside this range. Only 15% of participants slept between 7 and 9 hours for at least 5 nights per week.
