1. Sleep Deprivation and Exercise Michelle, Hannah, Eliza, and Eliana

2. Later start time  Teens have trouble falling asleep before 11pm  Their deepest sleep point is around 7am  After or the time that most teens wake up for school

3. Early Morning Classes  Test showed that students who were assigned early morning classes didn’t perform as well  Their grades were lower overall compared to students in classes with later start times

4. What happens when you don’t sleep? Sleep Deprivation links to…  Depression, suicide thoughts, weight gain, risky behavior in teens  Teens who drive/walk to school without enough sleep or while its dark are more likely to have accidents

5.  Tendency to get up later until age 19.5 in women and 21 in men  At this point they start waking up earlier again  By the age of 55-60 you are waking up the same time you were at the age of 10

6. Exercise and the Brain

7. Chemicals Roles  Serotonin: lifts mood  Epinephrine: response to stress/ fear  Dopamine: signals pleasure and makes you happy  Endorphin: bodies natural pain killer

8. Why exercise is necessary  Increases blood calcium which stimulates dopamine production and uptake in your brain  Helps produce serotonin/ epinephrine/ dopamine/ endorphin  These chemicals can help students by lifting their mood, keep them active and healthy, and give them a break from academic classes like science, history, language arts, math, etc.

9. Breaks from academic classes  Down time and breaks from classes like math or history help reinforce new connections of new things you’ve learned that day  That is why we have gym class for 4 th period- to help strengthen things you learned in the first 3 periods  It is important to support these new memories so breaks are important

10. Gym class every day  Gym is a good way of exercise  Exercise elevates mood by producing the chemicals we just mentioned  It is necessary for Middle school students to have a good mood because if they didn’t they could get stressed and stress has a negative impact on the brain

11. Updated Schedule

12. With our new schedule…  Classes will start two hours later because the teen brain stops developing melatonin later than adult brains which makes them tired and less focused in the morning  Gym class everyday before lunch so students get daily exercise  School ends at 4:10 PM, still leaving enough time for an after school activity
