WRAIR’s Sleep Research Center leads the most comprehensive study of sleep restriction ever attempted

Building on a storied legacy of pioneering sleep research, a collaboration among the Walter Reed Army Institute of Research, the National Institutes of Health, and the National Intrepid Center of Excellence—launched in April 2023—is undertaking the most comprehensive study of chronic sleep loss ever attempted.

The project, led by Dr. Samantha Riedy of WRAIR’s Sleep Research Center, leverages over a century of groundbreaking achievements—from early functional brain scans during sleep to the development of innovative monitoring techniques—to explore how consistently obtaining five or fewer hours of sleep (known as “chronic sleep restriction”) affects both brain function and overall health. With data collection set to conclude in March 2025, this study not only addresses a pressing modern public health challenge but also continues the Center’s tradition of scientific excellence and innovation in sleep research.
