  3. Why are some reasons we need sleep?

  4. Sleep allows our body to rest and repair itself • Sleep: • Allows our body to rest • Our muscles, our senses • Gives us energy, makes us alert • Improves movement and coordination • Helps brain to repair and reorganize • Allows for learning and memory • Improves mood

  5. Some parts of our body slow down: • Breathing • Heart rate • Digestion • Other parts speed up: • Our BRAIN Sleeping is an active process

  6. Brain activity is measured as electric waves A special machine measures and records our brain waves, as reflected in an electroencephalogram (EEG)

  7. Different types of brain waves exist during our sleep cycle

  8. There are two types of sleep: REM and Non-REM • REM: Rapid eye movement • Our eyes rapidly move back and forth underneath our eyelids. • Dreaming occurs • Video:http://www.youtube.com/watch?v=H0DJzFDOgzg • NREM: Non-REM sleep • The Sleep Cycle alternates between REM and NREM sleep.

  9. Stages of Sleep • Stage 1 and 2: We fall asleep, but are not in a deep sleep. • Stage 3 and 4: We are in a deep sleep, and our body’s activities slow down. • Stages 1 4 are part of Non-REM sleep. • Stage 5: REM sleep

  10. Video: The Science of Sleep • http://www.videojug.com/film/the-science-of-sleep-explained

  11. The hypothalamus helps regulate sleep The hypothalamus sets something called our biological clock

  12. The Biological Clock • Our biological clock controls when we go to sleep and when we wake up. Awake Asleep

  13. Clock-Dependent Alerting • Clock-dependent alerting (CDA) is a wake-up signal from our brains to maintain alertness. • CDA keeps us awake during the day, giving us periods of high alertness and energy.

  14. Sleep Need “Sleep need” is the amount of sleep we need to stay alert during the day. How many hours do teenagers need to sleep each night? How many hours did you sleep last night?

  15. Sleep debt • Sleep debt is when we get less sleep than we need. We need: We get: Sleep debt:

  16. Sleep debt adds up! 2 hours+ 1 hour+ 2 hours= 5 hours of sleep debt

  17. How do we get rid of sleep debt? • Pay it back! • The only way to eliminate sleep debt is to sleep extra. • Take naps

  18. Consequences of Sleep Deprivation • Too much accumulated sleep debt results in sleep deprivation. • Consequences: • Weight gain • Acne • Trouble concentrating in class • Poor sports performance • Bad mood • More likely to get sick • Poor memory • Slower reflexes

  19. Sleep Deprivation can be deadly! • Sleepiness while driving leads to at least 100,000 traffic accidents every year.

  20. Sleepiness Quiz! Activity:

  21. Sleep Hygiene: Good sleeping habits • Get 8-10 hours of sleep every night

  23. Sleep Hygiene: Good sleeping habits • Set a regular sleep schedule • Go to sleep and wake up at the same time every day.

  24. Sleep Hygiene: Good sleeping habits • Sync up with your biological clock • Take a nap when you are sleepy, study when you are alert. • Do not go to sleep too early or too late, or you will not be able to fall asleep.

  25. Sleep Hygiene: Good sleeping habits • Be active during the day, exercise regularly. • Avoid excitement or exercise right before bed.

  26. Sleep disorders: Obstructive Sleep Apnea • Two symptoms: Loud snoring and daytime sleepiness • Consequence: A person’s airway becomes blocked, causing them to stop breathing and forcing them awake.

  27. Sleep Disorders: Narcolepsy • The brain cannot control when and where a person falls asleep. • People with narcolepsy fall asleep suddenly and lose muscle movement. • Narcoleptic Dog Video: • http://www.bofunk.com/video/6297/skeeter_the_snoozey_poodle.html

  28. Sleep disorders: Insomnia • Insomnia: Difficulty falling asleep or staying asleep • Caused by stress, time zone change, noises, biological clock problems.
