Study Notes
Sleep Stages
-
Non-Rapid Eye Movement (NREM) Sleep:
- Stage 1: Transition from wakefulness to sleep, characterized by slow eye movements and a relaxed brain
- Stage 2: Body temperature cools, heart rate slows, and brain waves slow down
- Stage 3: Deep sleep, slow delta brain waves, and difficult to wake up
-
Rapid Eye Movement (REM) Sleep:
- Characterized by rapid eye movements, increased brain activity, and vivid dreams
- Brain waves similar to those during wakefulness
Sleep Cycles
- A full sleep cycle lasts around 90-120 minutes
- Each cycle consists of NREM stages 1-3, followed by REM sleep
- Most people experience 4-6 cycles per night
Sleep Functions
- Memory Consolidation: Processing and strengthening memories during sleep
- Clearing Waste: Removal of toxins and waste products from the brain during sleep
- Hormone Regulation: Release of hormones that help with growth, development, and appetite regulation
- Immune System Regulation: Regulation of the immune system and inflammation response
Sleep Disorders
- Insomnia: Difficulty falling or staying asleep
- Sleep Apnea: Pauses in breathing during sleep
- Narcolepsy: Excessive daytime sleepiness and sudden attacks of sleep
- Restless Leg Syndrome: Uncontrollable leg movements during sleep
Sleep Recommendations
- Adults: 7-9 hours of sleep per night
- Teenagers: 8-10 hours of sleep per night
- Children: 9-11 hours of sleep per night
- Establish a Bedtime Routine: Consistent sleep schedule and relaxing bedtime habits
Sleep Stages
-
NREM Sleep:
- Comprises stages 1-3, characterized by decreasing brain activity and increasing difficulty to wake up
- Stage 1: Transition from wakefulness, slow eye movements, and relaxed brain
- Stage 2: Cooling body temperature, slowed heart rate, and slowed brain waves
- Stage 3: Deep sleep, slow delta brain waves, and difficulty to wake up
-
