Powerpoint Presentation Circadian Rhythms

  2. 2. INTRODUCTION I started writing this paper basedon my curiosity of our circadianrhythms. I know that there are manythings that can affect our circadianrhythms, and alcohol is just a smallportion of it.
  3. 3. Purpose and Research Question•My purpose of this research is to see ifalcohol does in fact affect our circadianrhythms.•How does alcohol affect our CircadianRhythms?•My hypothesis is that alcohol does insome way affect our circadian rhythms.
  4. 4. Benefits to this Research •Understand it better •We blame other circumstances •Environment •Stress •Our uncomfortable beds
  5. 5. Circadian Rhythms What are Circadian Rhythms?  Our body clock  Sleep cycle  How we run our days
  6. 6. Circadian Rhythms Operate the same in every human body. Work on a 24 hour cycle, just like the Earth’s rotation.
  7. 7. Alcohol It affects our cerebellum (aka small brain), which controls many of our body’s functions.  Motor Skills (aka Balance)  Breathing
  8. 8. Alcohol Lowers body temperature  Been correlated to hypothermia Alcohol also has been researched to destroy certain brain cells.  Example: Studies show it destroys our GABA cells
  9. 9. How are they related? Body temperature drops when we intake alcohol, therefore our body has a harder time going to rest. Sometimes the intake of alcohol is too much, we get the “spins” as people say, which means that our balance and motions are off.  That makes it more difficult to sleep when the “spins” are taking place.
  10. 10. Conclusion Alcohol does in fact have an influence on our circadian rhythms. Circadian Rhythms are flexible. Alcohol is an inhibitor. Other factors that affect circadian rhythms.
