## Sleep Science Basics

### Sleep Architecture
- **Light Sleep (N1-N2)**: 50% of night
- **Deep Sleep (N3)**: 20% - physical restoration
- **REM Sleep**: 25% - mental restoration
- **Wake**: 5% - normal brief awakenings

### Circadian Rhythm
- 24-hour internal clock
- Light exposure is primary driver
- Consistency is key
- Individual chronotypes (early bird vs night owl)

### Sleep Pressure
- Builds throughout the day (adenosine)
- Caffeine blocks adenosine receptors
- Naps reduce sleep pressure

## Common Sleep Issues

### Difficulty Falling Asleep
- Racing thoughts
- Poor sleep environment
- Caffeine/stimulants
- Inconsistent schedule
- Blue light exposure

### Waking During Night
- Alcohol consumption
- Room temperature
- Blood sugar fluctuations
- Stress/anxiety
- Sleep apnea

### Not Feeling Rested
- Insufficient deep sleep
- Sleep fragmentation
- Oversleeping
- Poor sleep efficiency
- Underlying conditions
