In this episode of GoedeMorgenCommissaris, neuroscientist and sleep expert Els van den Helm guided us through the world of sleep. It’s common sense: sleep is important for personal well-being and performance. Insufficient sleep can cause cognitive impairments comparable to intoxication. Van den Helm’s research and experiences with various organizations shows that better sleep can significantly boost performance and reduce stress.

Personal and professional health

The dynamics of today’s world urge everyone to take good care of themselves, with sleep being a crucial component of that. Sleep has enormous impact on well-being and performance, both personally and professionally. The average person needs between seven and nine hours of sleep, but there is significant variability. Sleep debt can be calculated with interactive tests, which helps individuals to gain insight into their sleep habits and the consequences thereof. With sleep being essential for personal health, it also impacts the performance of organizations. Van den Helm states that poor sleep habits can lead to diminished cognitive functions and increased stress, ultimately affecting the productivity and effectiveness of teams.

Risks of sleep deprivation

Sleep deprivation has negative effects on decision-making. Perhaps the most striking example is the NASA Challenger disaster where poor decision-making was caused by lack of sleep. It is important to prioritize sleep because it forms a foundation for performance and well-being. Sleep deprivation can lead to a deterioration of mental and physical health. Research shows that people who do not get enough sleep consume more calories, are less likely to exercise, and are more vulnerable to stress. Sleep deprivation can lead to an increased risk of burnout and decreased performance. Statistics about the effects of sleep on cognitive performance show that individuals with a sleep deficit of eight hours exhibit performance levels comparable to those with a blood alcohol level of 0.1%. 

How to sleep better

Sufficient rest enhances creativity and problem-solving. Studies demonstrate improved cognitive flexibility and ethical behavior after a good night’s sleep. Individually, sleep quality can be improved by creating a favorable sleep environment, avoiding screen time before bed, and developing a consistent sleep schedule. Van den Helm also emphasizes the importance of napping as an effective way to compensate for sleep debt. Establishing clear boundaries and employing relaxation techniques, such as meditation, also help to improve sleep and overall performance.

In organizations leadership has a role by setting an example when it comes to sleep and well-being. In the media, leaders who sleep little are often glorified. This is a dangerous message, especially in high-stakes environments, where sleep is crucial for performance and safety. Leaders should foster discussions about sleep within their organizations and prioritize their own sleep as well.
