1. 24 bio clock
2. jet lag
3. melatonin (hormone) - sun -> hypothalamus -> pineal gland
4. manage what time we go to bed
1. Stage 1 - alpha waves: neural activity decreases
2. Stage 2 - sleep spindles: neural activity decreasing. Easily woken up.
3. Stage 3 & 4 - "deep sleep" - delta waves : brain is least active. Feel worse after getting 8 hrs. of sleep.
- "Paradoxical Sleep": Brain extremely active -> body is "locked down"; body doesn't move.
- Rapid eye movement
20 minute nap = coffee; 6-8 hrs. of energy; Stage 1 & 2
90 minutes = more energy (boost); Awake -> REM
Stage 3 & 4 - danger zone
1. 3/4 -> REM; REM increases the longer you sleep
2. REM Rebound - put body in REM earlier & stay in longer
3. Most in stage 2
-long-term potentiation/info processing (memory consolidation)
