In Sleep Restriction Therapy (SRT), your Time-in-Bed (TIB) prescription is adjusted weekly based on your average Sleep Efficiency (SE). This algorithm helps consolidate sleep, increasing homeostatic sleep drive.
Standard Algorithm
- SE > 90% (or >85% for seniors): Increase TIB by 15-30 minutes.
- SE 85% - 90% (or 80%-85% for seniors): Maintain current TIB.
- SE < 85% (or <80% for seniors): Decrease TIB by 15-30 minutes (never below 5-5.5 hrs).
