How workplaces can support healthier sleep habits and improve staff productivity
Sleep is often treated as a personal issue – something that’s generally kept separate from work. But new global research shows that sleep is one of the most powerful, and overlooked, drivers of workforce health, productivity, and, as a result, long‑term costs.
According to a major global study conducted by the Vitality Research Institute in collaboration with the London School of Economics and Political Science (LSE), poor and irregular sleep is one of the most underrated health risks worldwide. The analysis, which examined more than 47 million nights of real‑world sleep data, found that one in three adults globally fails to achieve the recommended seven hours of sleep per night.
For U.S. employers facing rising healthcare costs, productivity pressure, and workforce fatigue, the research helps show that sleep is no longer a “nice‑to‑have” wellbeing topic – it’s a strategic lever for prevention and performance.
According to the report, improving sleep can:
- Reduce healthcare costs by up to $287 per member per year, driven by fewer and shorter hospital admissions.
- Boost productivity: Poor sleepers lose the equivalent of 6.4 working days per year through absenteeism and presenteeism.
- Extend life expectancy by two to four years through improvements in both sleep duration and regularity.
The science of sleep
The Vitality and LSE research demonstrates that sleep directly influences health outcomes that matter to employers. The study found that insufficient or irregular sleep is associated with higher risk of chronic conditions, increased healthcare utilization, and reduced productivity.
Importantly, the research shows that sleep regularity matters just as much as sleep duration. Maintaining a consistent bedtime – falling asleep within a one‑hour window each night – was shown to be a stronger predictor of positive health outcomes than total sleep time alone.
From an employer perspective, this reframes sleep as a modifiable behavior, not a fixed trait. It also highlights why traditional wellness approaches that focus only on awareness often fall short.
As Christine Brophy, Vice President of Behavior and Engagement at Vitality, explains: “We don’t always think of sleep as a habit – but it is. Like physical activity or nutrition, sleep behaviors are shaped by daily choices and routines, and they can be improved when people are supported in the right way.”
The report proposes a simple, evidence‑based rule that distils sleep science into a habit‑forming behaviour: seven hours of sleep, within a one‑hour bedtime window, five nights a week.
This “7–1” rule meets the behavioural design principles that makes delivering shared value benefits to employees effective:
- It’s measurable via consumer devices.
- It’s memorable.
- It addresses behavioural biases such as present bias (“one sleep at a time”).
- It provides a clear cue and routine – both critical for habit formation.
Only 10% of people currently achieve this pattern consistently, meaning there is significant room for measurable improvement across a large population.
Why sleep is a business issue — not just a health one
The Vitality and LSE analysis links poor sleep to outcomes that directly affect business performance. The research estimates that improving sleep behaviors can help recover lost working days and reduce healthcare costs, highlighting sleep as a critical – and preventable – driver of economic loss.
For employers, the implications are clear:
- Fatigued employees are less focused, less productive, and more prone to errors
- Chronic sleep loss increases the likelihood of long‑term health conditions that drive medical spend
- Irregular sleep undermines mental resilience, engagement, and sustained performance
Rather than adding more programs or interventions, sleep represents an opportunity to optimize what employees already do every day – rest and recover.
The role employers play in supporting better sleep
Although sleep happens outside of working hours, the research reinforces that workplace culture strongly influences sleep behavior. Long hours, blurred boundaries, and constant digital engagement make it harder for employees to maintain consistent routines.
The Vitality and LSE white paper emphasizes that small, realistic behavior shifts – such as consistent bedtimes – can deliver measurable benefits when adopted at scale.
That means employers can have real impact by:
- Encouraging healthier boundaries around work and recovery
- Supporting realistic routines rather than perfection
- Integrating sleep into broader prevention and wellbeing strategies
As the research highlights, sleep should be treated as an active behavior – one that can be measured, practiced, and improved over time.
How Vitality supports healthier sleep habits
Vitality U.S. applies these global insights by focusing on behavior change, engagement, and prevention – rather than one‑off interventions.
By encouraging consistent healthy behaviors and reinforcing them over time, Vitality helps employers:
- Address sleep as a foundational driver of long‑term health risk
- Support employees in building sustainable daily routines
- Strengthen the link between wellbeing investment and business outcomes
What the Vitality and LSE research ultimately demonstrates that when sleep is approached as a habit – supported by data, feedback, and incentives – it becomes a powerful tool for improving population health and productivity at scale.
Global evidence now makes one thing clear: sleep is not a soft wellbeing issue – it’s a measurable (through wearable devices) and preventable risk factor with direct implications for workforce performance and healthcare costs.
By encouraging and enabling employees to use real‑world data to understand their sleep – and by supporting better sleep habits through smarter engagement – employers can unlock meaningful gains in health, productivity, and resilience.
A good night’s sleep isn’t just good for employees. It’s good for business too.
