And Why It’s Not Just a Personal Issue
Sleep has always been treated as an individual responsibility.
Get more of it. Improve your habits. Switch off earlier.
But that thinking is starting to fall short.
Because for many employees today, the issue isn’t just sleep.
It’s anxiety about sleep.
And increasingly, that anxiety is being shaped by work itself.
The problem most organizations fail to see
Sleep anxiety shows up in a very specific way.
The workday ends but it doesn’t. Mentally, that is. The person continues in work mode.
People lie in bed thinking about:
- Whether their boss likes them
- Deadlines they haven’t finished
- Conversations that didn’t go well
- What’s waiting for them tomorrow
- And whether they’ll be able to cope
The body may be resting but the mind is in full work mode.
That’s where recovery breaks down.
From restless nights to weaker performance
When sleep is disrupted, the impact isn’t subtle.
It shows up the next day in how people think, respond, and perform.
Employees experiencing sleep anxiety commonly report:
- Reduced concentration and focus
- Increased irritability
- Lower motivation
- More frequent mistakes
These are not isolated issues.
They directly affect how work gets done.
The real cost: more than lost time
Research shows employees can lose the equivalent of two working weeks per year due to poor sleep and fatigue.
That’s not just about absence.
It’s about reduced effectiveness while at work.
Across an organization, that leads to:
- Slower decision-making
- Lower quality output
- Reduced creativity
- Weaker collaboration
Financially, this translates into thousands in lost productivity per employee each year.
But the bigger issue is capability loss.
People are showing up.
Just not at full capacity.
Where leaders misdiagnose the issue
The default assumption is that sleep is personal.
Something employees need to manage better on their own.
But many of the triggers behind sleep anxiety are work-driven:
- Unclear or shifting priorities
- After-hours communication
- High workloads with no clear stopping point
- Constant cognitive load
When these are present, switching off isn’t a choice.
It’s a challenge.
A Mental Wealth perspective: performance starts with recovery
At WMHI, the focus is not just on reducing stress.
It’s on building capability in environments that support it.
Recovery is not separate from performance.
It is part of performance.
Sleep is a critical part of that.
If recovery is compromised, performance follows.
Which means this isn’t just a wellbeing issue.
It’s a leadership and design issue.
What organizations can do differently
Addressing sleep anxiety doesn’t require overhauling everything.
It starts with how work is structured day to day.
- Define clearer endpoints to work
When work feels unfinished, it carries into the night.
Clarity helps people mentally switch off.
- Set boundaries around after-hours communication
Even unread messages create cognitive load.
Small changes, like delayed sending, reduce that pressure.
- Increase predictability
Fewer last-minute changes mean less mental spillover after work. - Treat recovery as a performance lever
Not a benefit. Not a perk.
A requirement for sustained output.
The leadership reality
Sleep anxiety doesn’t start at night.
It starts during the day, in how work is experienced.
And over time, it shows up in:
- Lower energy
- Reduced focus
- Higher burnout risk
- Declining performance
This is not a marginal issue.
It’s a compounding issue.
Final thought
If people can’t switch off at night, it’s worth asking what’s making that difficult during the day.
Because the way work is designed doesn’t just shape output.
It shapes recovery.
And that, ultimately, shapes performance.
