You may
call yourself a night owl, but the reality of sleep deprivation is that staying
up too late is bad for your health.
“There
is no doubt that adequate duration and quality
sleep is important to our health,” said Peter Yau, MD, a
pulmonologist on the medical staff at Scott & White Memorial Hospital –
Temple who specializes in sleep medicine.
So if
you’ve been staying up late watching TV, reading articles on your smartphone,
or trying to get things done, it might be time to turn out the light.
You’ve
been telling yourself that you need to get more sleep, but what will it take to
really make a change?
You’re
not alone. Sleep deprivation is a real problem in America, and it is impacting
more than just young adults cramming for college exams. Many people are
suffering from poor sleep quality and poor sleep quantity. In fact, the Centers
for Disease Control (CDC) announced that insufficient sleep is now “epidemic” in America.
What Happens If I Don’t Get Enough Sleep?
If
you’re suffering from late nights and trying to combat them with caffeine, your
health may be suffering. Here are a few areas where sleep deprivation takes a
toll.
Stress
“Sleep
deprivation leads to increase cortisol level, which is the same hormone
released during stress,” Dr. Yau said. “Essentially being sleep deprived either
with quality or quantity can increase stress level.”
Are you
feeling stressed? Do you stay up late to get things done, thinking you’ll be
less stressed? It turns out this could have the opposite effect. As Dr. Yau
points out, this hormone may make you feel even more overwhelmed.
Brain
A study
published this year in the Journal of Neuroscience found that staying
awake too long destroys brain cells in mice, and may do the same in humans.
Researchers
at the University of Pennsylvania put mice under an irregular sleep schedule to
see the effects on the mechanics of the brain. Researchers found that 25
percent of the locus coeruleus was permanently damaged. This area of the brain
is responsible for alertness and cognitive thinking.
Forbes says, “It’s the
first study to show (if only in animals) that sleep loss can lead to
irreversible brain cell damage.”
It’s
clear that medical professionals and researchers agree — sleep is important for
our brain development and function.
Body
“Our
psychiatric well being, immune, endocrine, cardiac system and overall
performance level can be negatively impacted by sleep deprivation,” Dr. Yau
said.
Sleep
impacts all areas of life. If we stay up late, we may tend to snack on
unhealthy foods, impacting our diet and throwing off a healthy routine. If we
fail to get the proper amount of sleep, we may get sick more often, have heart
issues or become anxious or depressed.
Poor performance
If you
think you function better late at night, you may need to think again.
“Staying
up late leads to sleep deprivation, which can be counterproductive in ‘getting
things done,’” Dr. Yau said. “Your focus worsens, and productivity decreases.
Being sleep deprived results in similar performance as being intoxicated.”
Irregular sleep habits
A
result from sleep deprivation may carry over into an unhealthy sleep schedule.
If you are repeatedly staying up late, you may feel the need to sleep in, thus
throwing off an ideal sleep cycle.
“Adults
are recommended to have six to eight hours of good quality sleep,” Dr. Yau
said. “Significant variability in bed time and wake time daily can lead to both
insomnia and hypersomnia.”
The
best thing to do for yourself is to get into a regular schedule of sleep and
wake times. This will help your body get into a routine, and know how to fall
asleep and wake up with the best results.
Sleep
impacts your productivity, relationships and overall health. If you’re
combatting your lack of sleep with caffeine or suffering from drowsiness, talk
to your doctor.
