A closer look at how targeted support for sleep can improve day-to-day functioning at work and improve mental health symptoms
Sleep is one of the most important and least visible drivers of performance at work. A cross-country analysis found that employees who sleep fewer than six hours per night lose the equivalent of roughly six additional working days per year due to absenteeism and reduced productivity compared to well-rested peers.
For employers, there is no easy way to see who is struggling with sleep or when sleep disruption begins to affect work. What often becomes visible instead are downstream effects that overlap with broader mental health and well-being concerns: rising burnout, reduced engagement, lower productivity, and increased healthcare utilization.
What is easy to miss is how closely sleep and mental health are connected. Poor sleep can increase vulnerability to anxiety, depression, and emotional exhaustion. At the same time, stress, anxiety, and burnout can disrupt sleep, creating a reinforcing cycle that gradually erodes well-being and work performance. Over time, persistent sleep disruption can make it harder for employees to focus, regulate stress, and sustain consistent performance.
This means sleep and mental health are not separate conversations. They influence one another over time. For employers, the implication is practical: supporting employee mental health may also help address underlying factors that affect sleep, resilience, and day-to-day functioning at work.
Sleep and mental health influence one another through a reinforcing cycle. Research across clinical and population studies has consistently found that sleep disruption can both contribute to and result from mental health challenges.
Key dynamics in this cycle include:
Left unaddressed, this cycle can gradually deepen strain across a workforce. Earlier research from Modern Health found that nearly 1 in 4 employees face both mental and physical health challenges, underscoring how interconnected these issues often are.
To better understand how behavioral health support may influence sleep over time, Modern Health conducted a longitudinal study of employee members using the Modern Health platform through their employer-sponsored benefit.
The study examined whether engagement with integrated behavioral health support, including therapy, coaching, and digital resources, was associated with changes in sleep quality over time, along with related outcomes such as depression, anxiety, and burnout.
Researchers followed 578 working adults who accessed Modern Health through their employer benefit and assessed sleep quality, anxiety, depression, and burnout at three points:
During this period, participants engaged with Modern Health’s multi-modal care approach, which includes:
This allowed researchers to examine how sleep quality changed over time and how those changes related to broader mental health outcomes.
Sleep disruption was common among working adult participants at the start of the study. At baseline, 42% of participants reported poor sleep quality. Those participants also had significantly higher levels of depression, anxiety, and burnout than participants who reported good sleep.
As participants engaged with Modern Health through their employer-sponsored mental health benefit, sleep outcomes improved over the 12-month period.
These findings suggest that sleep quality can improve over time when employees have access to integrated behavioral health support.
Mental health outcomes also improved among participants who reported better sleep over time.
Among participants who reported poor sleep at baseline but good sleep by the 12-month follow-up:
These findings highlight the close relationship between sleep and mental health, and suggest that improvements in one may coincide with improvements in the other.
Organizations are asking employees to continuously adapt: navigate change, build new skills, manage uncertainty, and sustain performance in demanding environments. That kind of adaptability depends on cognitive clarity, emotional regulation, and steady energy.
Sleep disruption undermines those capacities, and the workforce impact is measurable.
In day-to-day workforce settings, sleep disruption can show up as absenteeism, presenteeism, inconsistent performance, and greater difficulty navigating ongoing stress.
Against that backdrop, these findings carry practical implications for employers. When sleep improves, the benefits may extend beyond rest alone to areas that affect workforce stability, resilience, and day-to-day functioning.
For HR and benefits leaders, this suggests that providing access to integrated behavioral health support may help address underlying drivers of workforce strain.
Modern Health addresses sleep challenges within a broader behavioral health model that recognizes how stress, life stage, and everyday demands affect rest and recovery.
Support available through Modern Health includes:
The platform operates on an Adaptive Care Model that matches members with the right level and type of support that fits their needs. Care is structured so members can move between support modalities as their needs change.
Mental health care should improve more than symptom scores.
When people sleep better, they can regulate emotions more effectively, think more clearly, and show up differently at work. At scale, those shifts shape how teams function, how decisions are made, and how pressure is absorbed across an organization.
