How Sleep Deprivation Undermines Executive Performance (And How To Combat It)

We undoubtedly live in a world where everything seems to move at lightning speed. When it comes to business and leadership specifically, executives are often celebrated for their ability to tirelessly grind and burn the midnight oil to drive success. However, beneath the surface of this line of thinking that in certain circles has become the cultural norm, a silent health saboteur looms—sleep deprivation.

Regardless of job function, everyone requires adequate sleep, which the National Institute of Health says for adults is at least 7 hours of sleep per night. Regularly getting less than the recommended 7 hours of sleep nightly has been linked to an increased risk of poor health outcomes including depression, obesity, lack of cognitive function, stroke, heart disease, and a higher risk of death.

Like everyone else and arguably more, executives need sufficient rest to perform their functions optimally and to be clear-thinking leaders in their field, especially where the stakes are high when mistakes are made. In this article, we will shed some light on the profound impact sleep deprivation has on leaders specifically that will help shine a spotlight on quality sleep’s significance in the pursuit of leadership performance and excellence.

 The Toll of Sleep Deprivation Take On Executive Performance

Sleep quality is very specific to an individual. With that said, not all executives suffer from sleep deprivation. However, with mounting peer-reviewed studies showing the correlation between lack of sleep and a variety of health conditions including effects that can negatively affect decision making and emotional stability, it is important to understand the negative effects lack of sleep can have on someone who makes decisions that have implications for other people in addition to themselves.

Below are some of the negative consequences that can occur when leaders are lacking sound sleep.

  • Cognitive Impairment: Sleep is a fundamental biological necessity. Depriving the brain of adequate rest impairs cognitive functions such as attention, memory, problem-solving, and decision-making. A sleep-deprived executive might find it challenging to stay focused during critical meetings or make strategic choices that demand acute mental acumen. Researchers have found that even one night of sleep deprivation can impair an executive’s cognitive capabilities.
  • Reduced Creativity and Innovation: The lifeblood for successful leadership is innovation. Sleep deprivation hampers creative thinking, stifling the ability to generate fresh ideas and inventive solutions to complex challenges. Executives who operate on inadequate sleep may struggle to inspire their teams and foster a culture of innovation.
  • Emotional Instability: Sleep deprivation has a profound impact on emotional regulation. Executives deprived of sleep may experience heightened stress, irritability, and mood swings. Emotional instability can trickle down to interactions with colleagues, affecting teamwork, collaboration, and the overall organizational atmosphere, which can be costly if it leads to high turnover of team members.
  • Deteriorating Judgment: Effective decision-making is paramount in executive roles. Sleep-deprived individuals are more prone to biased judgments, taking unnecessary risks, and making poor choices. A single sleepless night can compromise executive judgment, potentially leading to costly errors in business strategy.
  • Decline in Productivity: It shouldn’t come as a surprise that sleep deprivation often leads to a decrease in productivity. A tired executive may spend more time on tasks that would normally be completed efficiently, resulting in a vicious cycle of diminished output and increased fatigue.
  • Weakened Communication Skills: Communication is the key to any human dynamic and especially when it comes to leadership. Sleep-deprived executives may struggle to articulate ideas coherently, listen actively, or engage in meaningful conversations. This impedes effective communication both within the organization and with external stakeholders.
  • Physical Health Risks: Sleep deprivation that is prolonged can contribute to a variety of increased health risks including obesity, diabetes, cardiovascular disease, and a weakened immune system. When leaders are juggling demanding work schedules and sleepless nights, they are vulnerable to health issues that can undermine their health and their performance at work.
  • Interpersonal Relationships Can Suffer: Outside of the boardroom, sleep deprivation can put strain on personal relationships that can add stress and further impair the executive’s work performance. Maintaining a healthy work-life balance will be key so that both professional and personal relations are not affected.

Strategies To Enhance Sleep & Performance

Now that we covered how sleep can affect an executive’s performance, let’s talk about some solutions. Below are a few strategies that can help you get a good night’s sleep so you are healthy and can perform your daily work functions.

  • Create A Sleep-Conducive Environment: Executives should create a bedroom environment that promotes restful sleep including minimizing sound and light, creating a consistent sleep schedule, and investing in quality bedding and a solid mattress.
  • Practice Healthy Sleep Hygiene: Good sleep hygiene consists of healthy habits that promote quality sleep including limiting screen time, avoiding caffeine, heavy meals, tobacco, and alcohol a few hours before bed since all these things can affect sleep. Regular practices like meditation may also be helpful.
  • Create Clear Work Boundaries & Time Management: Clear work-life boundaries should be established so that there is dedicated time for self-care and rejuvenation where the executive is fully disconnected from work responsibilities. To do this, utilizing a tool like time blocking can help with scheduling the time to recharge.
  • Lead By Example: When executives prioritize healthy sleep habits it can set a precedent for their teams. By demonstrating the value of well-rested leadership, it fosters a culture that respects the importance of sleep while also enhancing health and performance amongst the team.

Takeaway

The idea that high-level executives and decision makers thrive on minimal sleep to drive organizational success is both outdated and perilous. The reality is that sleep deprivation takes a heavy toll on executive performance including negatively affecting mood, decision-making capabilities, response time, creativity, and in the long-term, sleep deprivation can lead to serious health complications.

It is important that organizations understand and value the fact that when the mind and body are well rested, optimal leadership thrives. When executives prioritize quality sleep, they can lead with clarity and navigate the inevitable complexities of their role with both resiliency and grace.
