Lead Author and Institution
Prof. Matthew Walker
UC Berkeley - Center for Human Sleep Science
Main Results
- After 19 hours without sleep, cognitive performance degrades to a level equivalent to 0.05% blood alcohol concentration.
- 40% deficit in integrating new memories (hippocampal blockage).
Application in Deuswell
Deuswell tracks the "sleep debt" metric using wearable data to alert users when their cognitive performance drops below clinical safety thresholds.
