The Science of Slumber
When you sleep, specifically during SWS (Slow Wave Sleep), your pituitary gland releases Growth Hormone. This is when tissue repair happens. If you cut sleep short, you blunt this release. You also increase Cortisol (stress hormone), which is catabolic (eats muscle).
sleeping 5 hours instead of 8 can reduce fat loss by 55% and increase muscle loss by 60% in a calorie deficit.
Tracking Recovery
Fitblues allows you to log sleep duration and quality. Users with wearable integrations (Apple Health) can sync this automatically.
The app calculates a "Recovery Score" (0-100).
- Score < 40: The AI Coach suggests a Rest Day or Mobility session.
- Score 40-70: Normal training volume.
- Score > 80: Go hard. You are primed for performance.
Sleep Hygiene Tips
Fitblues offers educational content on improving sleep:
- Blue light reduction (No screens 1h before bed).
- Temperature control (Cool rooms sleep better).
- Caffeine timing (Stop at 2 PM).
Conclusion
You can't out-train a bad diet, and you can't out-diet bad sleep. Prioritize recovery as much as your workout, and use Fitblues to keep you honest.
