Sleep Less, Die Early

  1. 1. SLEEP LESS, DIE EARLY 5 REASONS WHY SLEEP LOSS CAN SHORTEN YOUR LIFE SONIA WIBISONO
  2. 2. Not getting enough sleep each night can lead to serious health risks. It can also have long lasting, possibly permanent, negative impact on your body and mind.
  3. 3. 5 REASONS WHY SLEEP LOSS CAN SHORTEN YOUR LIFE COMPILED FROM DIFFERENT SOURCES, ALL BASED ON SCIENTIFIC RESEARCHES
  4. 4. REASON #1 SLEEP LOSS DECREASES IMMUNITY
  5. 5. #1: DECREASES IMMUNITY People who are sleep deprived have poor antibody response to flu vaccine—less than 50%—compared to people with enough sleep. Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu
  6. 6. #1: DECREASES IMMUNITY People who are sleep deprived have 73% lower natural killer cells activity, which plays a major role in fighting tumors, cancer, and virus infected cells. A natural killer cell Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu

  8. 8. REASON #2 SLEEP LOSS INCREASES RISK OF DIABETES
  9. 9. #2: INCREASES RISK OF DIABETES Sleep loss can make your body become more insulin-resistant. What that means is normal levels of insulin do not trigger glucose absorption. Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu
  10. 10. #2: INCREASES RISK OF DIABETES As a result, pancreas releases even more insulin, which will result in a drop in blood sugar. Insulin-resistance can progress to type-II diabetes, which can reduce your life expectancy by up to 10 years. Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu
  11. 11. REASON #3 SLEEP LOSS INCREASES RISK OF OBESITY
  12. 12. #3: INCREASES RISK OF OBESITY Lack of sleep can cause an imbalance between the two hormones of hunger. Sleep loss results in lower leptin (“do not eat” hormone) and higher ghrelin (“eat” hormone). Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu
  13. 13. #3: INCREASES RISK OF OBESITY Consequently, you will feel hungry all the time and usually crave foods high in carbs in particular. Even after eating, you might still feel unsatisfied. This can ultimately lead to obesity. Note: obese people live 3-12 years less than normal-weight people. Walker, M. P. Sleep Deprivation I: Immune Function & Metabolism [PowerPoint slides]. Retrieved from http://bspace.berkeley.edu
  14. 14. REASON #4 SLEEP LOSS INCREASES RISK OF STROKE
  15. 15. #4: INCREASES RISK OF STROKE Studies show that if you get less than six hours of sleep per night, you have a 48% greater chance of developing/dying from heart disease and 15% greater chance of developing/dying from stroke. http://www.theguardian.com/lifeandstyle/2011/feb/09/sleep-medical-research
  16. 16. #4: INCREASES RISK OF STROKE Poor sleep increases the production of stress hormones and drives up blood pressure, a major risk factor for heart attacks and strokes. http://en.wikipedia.org/wiki/Sleep_deprivation
  17. 17. REASON #5 SLEEP LOSS INCREASES PROBABILITY OF ACCIDENTS
  18. 18. #5: INCREASES PROBABILITY OF ACCIDENTS Sleep deprivation was cited as a significant factor in these catastrophes: • Three Mile Island’s partial nuclear meltdown in March 1979 • Nuclear meltdown at Chernobyl in April 1986 • Exxon Valdez oil spill in March 1989 http://healthysleep.med.harvard.edu/healthy/matters/consequences/sleep-performance-and-public-safety
  19. 19. #5: INCREASES PROBABILITY OF ACCIDENTS The National Highway Traffic Safety Administration conservatively estimates that 100,000 police-reported crashes are the direct result of driver fatigue each year. It takes only 4 seconds of attention lapse to result in a potentially fatal crash. http://drowsydriving.org/about/facts-and-stats/ Walker, M. P.
