Your Sleep Deprivation Is Contagious: Why Rested Leaders Build Psychological Safety And Compassion

9 Jun

It’s Thursday morning and I’m about to embark on a 40-hour trip from Brisbane to Madrid with my husband and two young kids. ‘What could possibly go wrong with my sleep?’ she says naively.

Anyone who’s done this trip, with or without kids, knows that sleep is hard to come by when you’re sitting upright and tightly squeezed into a tin can hurtling through the sky. And while I can’t control every element about this situation, I’m already aware that the whole family will end up tired and grumpy and at some point someone will probably lose their temper. So I’ll be doing what I can to make sure that sleep is a big part of our pre-flight and post flight recovery plan so we can make the most of the fun parts of travelling overseas.

While sleep is a big factor in overseas travel, it also plays a central role in how organisations function. Imagine a leader in a tense meeting, exhausted, and running on their third coffee. When a team member asks a legitimate question, the leader misreads it as criticism and shuts the conversation down. In that moment, psychological safety collapses, not just between the two of them, but within the whole team.

They don’t think, ‘Well, our leader is tired, they didn’t mean to snap", because most people don’t look deeper into the underlying reasons for someone’s behaviour, especially when they’re under the pump and don’t know each other well. They’re more likely to think that their work environment is not a safe space to speak and ask questions, and this isn’t something that can be easily fixed.

So when it comes to leadership, one of the most powerful strategies for a leader who wants to be great is to be well-rested.

Sleep Deprivation: The Risk in Modern Workplaces

Sleep deprivation narrows the gap between stimulus and response. When we're exhausted, our amygdala, the brain's threat-detection centre, hijacks our prefrontal cortex, which handles reasoning, empathy, and perspective-taking.

A tired leader becomes reactive. Sometimes the exhaustion is not even overt, because the leader is doing their best to keep a lid on it. So the exhaustion shows up in a micro-expression of frustration, a clipped word, a dismissive body gesture, signals that tell teams it’s not safe to bring their problems to the table.

This is especially problematic in workplace wellbeing because nervous systems sync. Mirror neurons create contagion within teams. When a leader's nervous system is dysregulated, anxious, and reactive, the team mirrors it back. Conversely, a regulated, rested leader creates calm ripples outward. The whole system becomes safer, more creative, and more resilient.

This is why, when leaders are depleted, workplace wellbeing initiatives fail. You can't build psychological safety on a foundation of exhaustion.

Sleep supports Emotional Intelligence and Compassion

Emotional intelligence requires something sleep deprivation destroys: the ability to pause. Being able to pause means finding the space between what we feel and what we do.

Jeff Bezos, Microsoft's Satya Nadella, and other high-performing leaders prioritise at least 8 hours of sleep nightly, and they're explicit about why. Bezos schedules all mentally demanding meetings for 10 a.m., avoids major decisions after 5 p.m., and focusses on having a very analogue, slow-start morning with his family. In a 2018 interview Bezos said, "I think better, I have more energy, and my mood is better" with adequate sleep.

Good sleep shouldn’t be seen as a luxury. Being well-rested creates the infrastructure for genuine compassion, and compassion is an essential trait for a leader. Compassion isn't something you can summon through willpower, and it’s hard to find when exhausted.

Compassion is a neurological capacity that only emerges when your nervous system has the bandwidth to access it. A well-rested leader can sit with a colleague's struggle without rushing to fix it. They can see the person, not the problem. This is the nervous system capacity that actually holds psychological safety, and it depends on a stable and rested nervous system.

For organisations investing in leadership development and leadership training programs, sleep and rest is a key development piece that’s often missing.

How Psychological Safety Cascades From Rest

By now it should be clear, there is a cascade of events that take place when a leader is recovered and rested. The pattern looks something like this:

Leader sleeps → regulated nervous system → less reactivity → calmer responses → team feels safer → people speak up, contribute, admit mistakes → leader has the bandwidth to respond with curiosity, not judgment.

A rested leader can be curious, not as a tactic, but because they’re genuinely interested and open rather than defensive and scanning for threats. A team can recognise this difference. This is what workplace wellbeing consultants should be teaching.

Real Examples: Organisations That Prioritise Sleep

Aetna CEO Mark Bertolini is incredibly invested in the wellbeing of his employees. His initiatives have gone way beyond performative wellness perks into creating sustainable and measurable programs that impact employees and improve the metrics of the company. From 2014-2016 and beyond Aetna ran a program where employees tracked their sleep using devices like Fitbits. Employees earned USD$25 per night when they slept seven or more hours for 20 consecutive nights, and were able to earn up to USD$500 annually. The first year of Aetna's comprehensive wellness program, which included yoga, meditation, and sleep education, Aetna's health care costs dropped 7.5 percent.

It’s clear that Bertolini understood that when you're exhausted it permeates into your work and your relationships. When executives visibly protect their sleep, refuse to glorify late nights, and refrain from sending emails after hours, they send a cultural message: "Rest is how we take care of ourselves and each other." This is the kind of modelling where workplace wellbeing ripples out into the organisation. This is what proactive wellbeing strategies look like, and they demonstrate an organisation that is actively seeking to prevent psychosocial risks for their leaders and their teams.

Accessibility and Inclusion

Sleep is vital for those already struggling with stretched schedules. This can look like parents who are managing night wakings, caregivers running on inadequate down-time, neurodivergent employees, and anyone whose sleep is interrupted by circumstances beyond their control.

When leaders normalise conversations around sleep challenges and build flexible cultures around them, it’s not a soft approach. Leaders who are willing to talk about sleep are being compassionate and inclusive. They're acknowledging that exhaustion does affect you’re ability to show up well at work. This is what compassion-centered leadership training should address.

Reframing sleep in Leadership

Sleep is self-care, but it shouldn’t be relegated to the ‘nice-to-have’ bin. Sleep is the leadership infrastructure you need for sustainability.

Successful leaders aren't the ones who hustle hardest. They're the ones who sleep, stay regulated, and create conditions where their teams can do the same. They work with compassion and create the psychological safety that keeps organisations thriving. All that’s needed is the courage to rest and the systems to make it work.
