Vitality Data Reveals ‘Super Sleepers’
New analysis from Vitality, the next-generation health and life insurer, has identified a cohort of 'Super Sleepers' who avoid the detrimental health outcomes typically associated with short sleep. The ‘Super Sleepers’ are a cohort of adults under 60, without chronic conditions, who all exercise consistently and whose sleep architecture reflects good quality rest.
The data suggests that, for this group, sleeping between five and six hours does not produce the adverse health outcomes typically associated with short sleep. Crucially, the analysis identifies that consistent exercise, a minimum of three times per week, is the primary factor enabling this cohort to become ‘Super Sleepers,’ providing them with a unique resilience to shorter sleep durations.
The traits and behaviours of the 'Super Sleeper' cohort include:
- Aged under 60
- No chronic conditions, such as hypertension or diabetes
- Regular exercise – at least three sessions of 30 minutes per week
- Consistent bedtime with variation of no more than 45 minutes night-to-night
- Sleep architecture consistent with good quality rest: at least 16% deep sleep and 23% REM sleep
The analysis draws on wearable device data across more than 150,000 Vitality members and shows that rather than the hours slept, the time people go to bed and the consistency of their sleep are two of the biggest factors in determining health outcomes for this group.
This builds on Vitality's research published with the London School of Economics (LSE) earlier this year, which found that adopting consistent positive sleep behaviours could add up to two years to life expectancy and reduce mortality risk by almost a quarter. That study, which tracked more than 47 million nights of sleep, also found that bedtime consistency was an even stronger predictor of health risk than hours slept alone.
The prevailing consensus and current guidelines recommend seven hours of sleep per night to support broader health. Vitality's member data shows many adults fall well below that target: 36% of members sleep less than seven hours per night, of which 16% sleep less than six hours. Falling short of the seven-hour guideline is associated with a range of adverse outcomes, including cardiovascular disease, metabolic dysfunction and cognitive decline. Vitality analysis verified by the LSE shows that achieving more than seven hours of sleep is associated with an 8% reduction in in-hospital claims compared to those sleeping less than seven hours. This same 8% reduction is also observed among ‘Super Sleepers,’ individuals who achieve high sleep quality scores despite shorter durations, when compared to those with low sleep scores resulting from poor duration.
With a significant proportion of adults consistently falling short of current guidelines, the question becomes how adults can better protect their health through sleep. Broad guidelines have their place, but the research suggests that, for this cohort at least, the answer isn't necessarily more sleep — it's a personalised approach: an active lifestyle paired with a consistent bedtime and sleep duration.
Katie Tryon, Deputy CEO of VitalityHealth, said: "For years, the message has been simple: get eight hours or face the consequences. Our data tells a more nuanced story. Broad sleep guidelines have their place, but what this data shows us is that a personalised approach — one that accounts for lifestyle, activity levels and sleep consistency — can be a more meaningful guide to health than a universal hour-based target. This is a specific finding about a specific cohort: younger, active adults without chronic conditions, where lifestyle factors, sleep quality and consistency matter as much as duration. We have seen members sleeping under six hours avoid the negative health outcomes typically associated with short sleep, but only when their bedtime and sleep length are consistent, night after night. This builds on our research with LSE, which showed that consistent sleep behaviours alone can add up to two years to life expectancy. Together, this tells us that how — and when — we sleep can matter just as much as how long."
Notes to editor
This data is based on analysis of sleep and clinical outcomes data from more than 150,000 Vitality members in South Africa who actively engaged with the Vitality Sleep benefit following its launch on 1 May 2026. Sleep data is derived from wearable device data submitted by members through the Vitality app.
Additional context statistics on sleep, mortality risk and life expectancy are drawn from separate research published by Vitality and the London School of Economics (LSE) in February 2026, which analysed more than 47 million nights of sleep.
The Vitality Sleep Score is a personalised metric that aggregates sleep duration, quality and consistency data, then links it directly to health outcomes using causal inference modelling across the Vitality member population.
