Study Notes
Importance of Sleep
- Sleep is essential for survival and functioning.
- During sleep, the brain is active, organizing and storing daily events for easy retrieval.
Brain Function During Sleep
- The brain clears away waste products that build up during the day.
- Deeper sleep enables more effective brain cleaning.
Sleep Requirements
- Adults need 7-9 hours of sleep for maximum brain performance.
Consequences of Insufficient Sleep
- Impairs ability to remember and concentrate.
- Leads to mood swings, irritability, and increased risk of anxiety and depression.
- Impairs judgment and performance, similar to being drunk.
- Increases risk of accidents and injuries.
- May increase risk of dementia over time.
Good Sleep Hygiene
- Put away electronic devices 1 hour before bedtime.
- Engage in relaxing activities before bed.
- Establish a consistent sleep schedule.
- Avoid stimulants like caffeine and alcohol in the late afternoon or evening.
- Avoid heavy meals before bedtime.
- Create a quiet, cool, and dark bedroom environment.
- Engage in moderately intense exercise (at least 30 minutes) on most days to improve sleep and overall health.

Importance of Sleep
- Sleep is crucial for survival and functioning, as it enables the brain to organize daily events and file them for later retrieval
- During sleep, the brain performs "housekeeping" by clearing away waste buildup from the day
Benefits of Deep Sleep
- Deep sleep is essential for effective brain cleaning and optimal brain performance
- Adults need 7-9 hours of sleep to maximize brain performance and cognitive function
Consequences of Insufficient Sleep
- Insufficient sleep impairs memory, concentration, and judgment
- Lack of sleep leads to mood swings, irritability, and increased risk of anxiety and depression
- Prolonged sleep deprivation impairs performance, increases the risk of accidents and injuries, and has similar effects to being drunk
- Chronic sleep deprivation may increase the risk of dementia and other long-term health consequences
Good Sleep Hygiene
- Establish a consistent sleep schedule to regulate the body's internal clock
- Create a sleep-conducive environment: quiet, cool, and dark to improve sleep quality
- Avoid stimulants like caffeine and heavy meals before bedtime to promote relaxation
- Engage in relaxing activities before bedtime to calm the mind and body
- Engage in moderately intense exercise (at least 30 minutes) on most days to improve sleep and overall health
