Take Back Your Sleep

You’re not just tired. You’re missing the deep, restorative sleep you need.

You already know sleep matters. What most people don’t realize is that even with a full night in bed, the brain may not be getting the deep, restorative sleep it needs—and that gap affects how you think, decide, and perform.

In Take Back Your Sleep, Dr. Ana Casas, MD, and Victoria Dhar, MSc, combine clinical medicine and sleep neuroscience to show how deep sleep drives clarity, resilience, and long-term brain health. Drawing on real-world work with executives and high performers, they reveal how modern life disrupts sleep, and how to restore it.

You’ll learn how to:

• Increase deep sleep to improve focus and decision-making
• Reset your internal clock, even with travel or irregular schedules
• Calm your nervous system for consistent, high-quality sleep
• Build simple routines that support energy, performance, and longevity

Deep sleep is where your brain clears waste, processes information, and resets for the day ahead. When you improve it, everything else gets easier.
