Episode notes
Manipulate Temperature For Faster Sleep
- Use cooling pillows or keep ambient bedroom temperature low (60–68°F) to promote sleep.
- Warm your feet or wear socks before bed to trigger distal warming and lower core temperature to fall asleep faster.
Consolidate Time In Bed For Insomnia
- For insomnia, use sleep restriction to consolidate sleep and boost homeostatic sleep drive.
- Avoid naps and reduce time in bed until sleep efficiency improves.
Use Sensory Cues To Boost Memory
- Use targeted memory reactivation: pair a sensory cue during learning and replay it in light sleep to boost consolidation.
- Replay cues softly so they prime memory without waking you.
