SLEEP LESS, DIE EARLY5 REASONS WHY SLEEP LOSS CAN SHORTEN YOUR LIFE
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.
5 REASONS WHY SLEEP LOSS CAN SHORTEN YOUR LIFE

SLEEP LOSS DECREASESIMMUNITY
REASON #1
#1: DECREASES IMMUNITY
People who are sleep
deprived have poor
antibody response to
flu vaccine—less
than 50%—compared
to people with
enough sleep.

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

SLEEP LOSS INCREASESRISK OF DIABETES
REASON #2
#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
#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.

SLEEP LOSS INCREASESRISK OF OBESITY
REASON #3
#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
#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
SLEEP LOSS INCREASESRISK OF STROKE
REASON #4
#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
Poor sleep increases the production of stress
hormones and drives up blood pressure, a major
risk factor for heart attacks and strokes.

SLEEP LOSS INCREASESPROBABILITY OF ACCIDENTS
REASON #5
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

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.

Now that you understand
how less sleep can cause early death,
you might want to consider
shutting down your computer
and get some sleep.
