Grade Level:
11/12
Subject:
Sociology
Overview- Everyone cycles through different levels of awareness when sleeping. The Reticular
Activating System in your brain is responsible for controlling your cycle. Your hypothalamus also
plays a role in regulating body temperature, BP and heart rate. Sleep Deprivation can cause
longterm health problems. Infants need more sleep than adults. NREM sleep goes from twilight
sleep to Stage 4. REM (Rapid Eye Movement ) sleep cycles every 90 minutes and the brain is highly
active during this phase.
Do Now:
Do Now: Have you ever had jet lag? Have
you ever had a hard time adjusting to

symptoms?
They Do: Continue to keep track of their
sleeping patterns in sleep journal.
