Experts About Sleep Intelligence
In high-pressure environments,
sleep is often the first thing we sacrifice
With packed schedules, constant demands, and never-ending to-do lists, there never seems to be enough hours in the day. So you work a little longer, go to bed a little later, and tell yourself you’ll catch up on sleep when things calm down. But have you noticed how much harder it becomes to stay focused during meetings, make clear decisions, or remain patient with your colleagues after a few short nights? The effects of sleep deprivation often go unnoticed, even as they begin to affect how we think, feel, and interact with others. What if the very thing you’re sacrificing to get ahead is holding you back?
In Sleep Intelligence, sleep neuroscientist and executive advisor Dr. Els van der Helm, PhD, challenges the idea that sleep is simply a habit to optimise or a matter of willpower. Drawing on neuroscience and real-world experience, she introduces a practical framework for understanding sleep and making it a strategic foundation for sharper thinking, stronger leadership, and sustainable performance.
