Sleep Deprivation


Hey You Guys! 

Sleep Deprivation or sleep loss refers to “sleep of shorter duration than the average basal need of 7 to 8 hours per night” (Institute of Medicine 2006). As college students, most can relate to this sleep pattern and even see it as a normatively. Sleep Deprivation in college students is caused by a variety of different factors including schedule, stress, and social activities. College students are sometimes forced to make a class schedule that is outside what they have previously been accustomed too. Waking up to go to an early morning class, for someone who has previously been known as a night owl, can be difficult to get used to. The stress that comes with being a college student can greatly affect quality of sleep as well. A study in 2001 showed that 73% of students have occasional sleeping problems due to stress (Knowlden 2012) The stress that comes with being a college student cause some to lose sleep, but what about the stress that people in developing countries face every day? Are these sleep loss trends consistent globally or is this solely an American epidemic?


The Five Stages of Sleep- Describes if the Sleep we are getting is restful. REM stands for Rapid Eye Movement because the eyes wander back and forth at this stage (WebMD).

Stage 1- (Non Rem) Theta Waves are present and patients will claim they weren’t asleep (WebMD).

Stage 2-(Non Rem) Rapid brain waves called sleep spindles occur. Heart rate decreases (WebMD).

Stage 3-(Non Rem) Delta Waves Occur and patient will drift from light to deep sleep (WebMD).

Stage 4-(Non Rem) Delta Sleep occurs, bed-wetting or sleepwalking occurs at this  time (WebMD).

Stage 5-(REM) Increased respirations rate and brain activity (WebMD).

Important-  If stage 5, REM stage, isn’t reached… signs of sleep deprivation can still occur (WebMD).


Effects of Sleep Deprivations 


Cognitive- Sleep deprivation is far too common in modern society yet can have many effects on a person.  One negative effect that insufficient sleep can have is on the cognitive performance (Result Filters).  It will generally slow the response speed of a person and increase the inconsistency of a person’s alertness making them in a vulnerable state.


Immune System- The immune system is one part of the body that is negatively affected by the lack of sleep. The response of immune system during sleep deprivation can cause disruptions in beta cells and compliment pathways that help fight infection. (Segerstrom and Miller, 2004).  


Mood- More than the effects on cognition, another negative effect from sleep deprivation is the profound effect on mood (Pilcher). Lets face it we all get irritable during finals week. As a group we ponder if closing the book and getting a full night of sleep would give us a higher grade.


Weight- Another effect on persons, especially women, that obtain insufficient sleep is weight gain.  “Sleep restriction has metabolic effects that predispose to weight gain” (Patel).  Due to the inability to have sufficient cognitive performance, people are less likely to make the best decisions such as good food choices and healthy lifestyle decisions.  Sleep deprivation has completely underestimated effects on the functions of the human body.


Physical Aspects- Inadequate sleep can lead to detrimental effects on the body. The physical aspects of sleep deprivation have profound effects on the body (Matta). The physical aspects of insufficient sleep are forgetfulness, difficulty in concentration, and decreased sociability (Matta). With these physical effects in mind, a person will less productive in the workday and school.


Higher Risk of Chronic Disease- Another detrimental effect of sleep deprivation is the increased risk of chronic disease (Colten and Altevogt, 2006). With the increased risk of chronic disease and less responsive immune system, a person’s overall health will be vulnerable. Regardless of age and gender, sleep deprivation negatively affects a person’s health. Examples of this is would be obesity and hypertension (Colten and Altevogt, 2006). Sleep Apnea is mentioned in Sleep Hygiene.

Sleep Hygiene- Sleep hygiene is in reference to non-medical treatment options to better ones slumber. Below are ways to improve ones sleep hygiene.

Obesity- When an individual is over weight it is most likely that they will suffer from sleep apnea (Marks, 2012). Sleep Apnea is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep (Marks, 2012). When patients are obese they often suffer from obstructive sleep apnea (Marks, 2012). They extra weight crushes their trachea creating a loud snoring sound or create long pauses where the body is deprived of oxygen (Marks, 2012). I lived with a person with obstructive sleep disorder and he would gasp from time to time like he was held under water. Not only is it scary to hear someone having to fight to breath when they sleep, they are often unrested and lethargic throughout the day (Marks, 2012). REM sleep is interrupted when you have to fight to breath while you sleep (Marks, 2012). Studies conclude that patients with sleep apnea are generally obese (Marks, 2012). Studies have also shown that people that get enough sleep crave fewer sweets and empty caloric food (Wilkey, 2012). If your news year’s resolution is to loose weight, add on the sleep.

Reduce intake of caffeinated beverages- Caffeine is a stimulate drug and a Northwest staple. It is also a crutch to college students during midterms and finals week. I was nine when I had my first coffee drink, and I don’t recall when my first caffeinated soda was. Studies show that no matter when caffeine is consumed it effects you sleep cycle (Woerner, 2013). That is right even a “cup of Joe” in the morning can impede sleep (Woerner, 2013).

Reduce alcohol intake- This suggestion surprised me because I find myself sleepy after having a glass of wine. It is common for me to hear a fellow student say, “I need to wind down” and opt for an adult beverage. Although alcohol is a depressant, therefore disturbs circadian rhythms and REM cycles (Szalavitz, 2013). This is one of the reasons why people whom have drunk the night before feel unrested after sleep (Szalavitz, 2013).  
Bed is for sleep only… Ok maybe one more thing- Sleep specialists claim that TV, eating, and discussing emotional issues in bed disrupt sleep cycles (Graven, 2012). Ladies, pillow talk is not longer considered cute and men you have a leg to stand on. The bed should be used for sleep and sexual acts only. If not, we can associate the bed with other activities and it often becomes difficult to fall asleep (Graven, 2012).

Meditation- A study at Yale University did a study on the relationship of meditation and sleep (James, 2011). Associates discovered that people that participated in the study that meditated regularly are basis are able to switch on or off the areas of the brain that is responsible for Attention Deficit Hyperactivity Disorder (ADHA), schizophrenia, and anxiety (James, 2011). The study finds these people become more mindful of their surrounding and not self-centered due to less activity in the “default mode network” of the brain (James, 2011). A new network is reported when brain activity is monitored through an (MRI) Magnetic resonance imaging device when a patient meditates (James, 2011). What does this mean to the sleep deprived? Fewer vices to keep people suffering from sleep deprivation awake, such as chocolate, caffeine, or nicotine (James, 2011). In order to do this an individual needs to turn busy beta wave state in their brain to an alert but calm alpha wave state (James, 2011). Alpha waves activate the parasympathetic nervous system (PNS), allowing the individual to slow down and the brain to regenerate (James, 2011). This will only take 10-15 minutes out of your day or before bedtime (James, 2011).

Medication- The use of medication is recommended by physicians only, these methods are reported to be a last resort. Over uses and abuse of prescription drugs can lead to addiction (Ogbru, 2013). 


Prescription- Many prescription drugs can cause drowsiness, but there is a whole class of drugs used to treat insomnia. The most common are called hypnotics (Ogbru, 2013). There are a variety of hypnotics we see on television commercials such as Ambien, Lunesta, and Restoril. The main difference among the various hypnotics is their half-life or how long the drug is active in the body before it is processed out of the body (Ogbru, 2013). This may sound like a “dream” come true. The list of possible side effects for prescription sleep aids is well of 25 items long and sound torturous (Ogbru, 2013).


Over the Counter- Example of these that I’m familiar with are Tylenol PM and melatonin supplements. Dr. Ogbru as states allergy medicine can bee used if you have problems sleeping (Ogbru, 2013).  These have been proven safe for consumption and addiction isn’t likely, although I would consult a physician before going on a nightly regiment (Ogbru, 2013).

Sleep Deprivation in the Developing World


Sleep deprivation in the developing world is not that well known. But recent research has shown the prevalence of sleep deprivation. A study was done in 8 developing countries (South Africa, Tanzania, Kenya, Ghana, Vietnam, Bangladesh, Indonesia, India) and across Asia and Africa in older adults age 50 and older (Stranges 2012). The results show that “16.6% of adults 50 and older reported sleep problems” (Stranges 2012). Assuming this is true across the entire developing world, this would mean about 150 million people have sleep problems in 2010 (Stranges 2012). In a related issue, a global study done by the United Nations on global aging shows that by year 2050, “for the first time in history, seniors older than 60 will outnumber children younger than 15” (as cited in Gelineu 2013). In the future, the entire world faces an increasing older population and with this an enormous challenge of sleep deprivation if nothing is done. But developing countries have additional hurdles that make addressing this issue more problematic. Taken all together, sleep deprivation is a global health issue that has not received the attention it needs to properly address the problem. The research we have presented is only from adults age 50 and older (Stranges 2012). This doesn’t include children and adults younger than age 50 (Stranges 2012). Our group speculates that the prevalence is even higher if all age groups were included.
