Basically, sleep deprivation is when one doesn’t get enough sleep. When someone is in a chronic sleep-restricted state they’ll notice excessive daytime sleepiness, fatigue, clumsiness, and weight gain or weight loss. In addition, being sleep-deprived affects both the brain and cognitive function.

Unlike other basic bodily functions, such as eating and breathing, we still do not fully understand why people need to sleep. There are theories, some think sleep may be the process by which the brain shuts down so it can store the day’s memories. Others, like Dr. Joyce Walseben, a psychiatrist and the former director of Bellevue Hospital’s Sleep Disorders Center, point to sleep’s importance in regulating the body’s hormones. But these theories are not complete.


Sleep deprivation is nearly as misunderstood as sleep itself, but it can physically and mentally harm people in myriad ways. Losing sleep can cause hallucinations, psychosis, and long-term memory impairment. Some studies have linked sleep deprivation to chronic conditions like hypertension, diabetes, and bipolar disorder. In 2003, neurologists at the University of Pennsylvania found that sleep deprivation over three consecutive nights (in the study, staying awake for 88 hours) as well as chronic sleep loss (in the study, four to six hours of sleep each night for 14 nights) seriously impaired cognitive functions in healthy adults. Also in 2003, Japanese researchers found that total sleep deprivation can cause high blood pressure and has “profound” effects on the immune system.

In 1989, at the University of Chicago, researchers observed rats which died after being kept awake non-stop for several weeks. (According to a 2009 article, specialists who have looked at the 1989 study dispute which effects of sleep deprivation ultimately killed the rats. It could have been hypothermia brought on by decreased body temperatures, illnesses that arose from damaged immune systems, or severe brain damage.) In July 2012, Chinese soccer fan Jiang Xiaoshan died after staying awake for 11 days to watch all of the European Football Championship. In August, a Bank of America intern died after three days of sleep deprivation.


There’s a subset of cases whereby sleep deprivation can actually lead to an enhanced mood, alertness, and increased energy. Note that relatively few studies have compared the different effects between chronic partial-sleep restriction and acute total-sleep deprivation, and the total absence of sleep over long periods of time has not been studied in humans.

When rats were exposed to prolonged sleep deprivation the result was that both food intake and energy expenditure increased, resulting in a net weight loss, and ultimately leading to death. The hypothesis of this study is that when moderate chronic sleep debt goes hand-in-hand with habitual short sleep, energy expenditure and increased appetite are encouraged; and, in societies where high-calorie food is freely available the equation is tipped towards food intake rather than expenditure. Nationally representative samples used in several large studies suggest that one of the causes of the United States obesity problem could possibly be due to the corresponding decrease in the average number of hours that people sleep. These findings indicate that the hormones that regulate appetite and glucose metabolism could be disrupted because of sleep deprivation. It appears that the association between obesity and sleep deprivation is strongest in young and middle-age adults. On the other hand, there are scientists who believe that related problems, such as sleep apnea, together with the physical discomfort of obesity, reduce a person’s likelihood of getting a good night’s sleep.

There have also been studies that show sleep restriction might have

potential when it comes to treating depression. We know that people suffering from depression experience earlier incidences of REM sleep, plus increased rapid eye movements; and monitoring a patient’s EEG and waking them during bouts of REM sleep appears to produce a therapeutic effect, thus alleviating symptoms of depression.

When sleep deprived, up to 60% of patients show signs of immediate recovery; however, most relapse the next night. It’s believed that this effect is linked to increases in the brain-derived neurotrophic factor (BDNF). It’s also been shown that, in normal people, chronotype is related to the effect that sleep deprivation has on mood: following sleep deprivation, people who prefer mornings become more depressed, while those who prefer evenings show a marked improvement in their mood. In 2014, a thorough evaluation of the human metabolome in sleep deprivation discovered that 27 metabolites are increased following 24 waking hours, with suggestions that tryptophan, serotonin, and taurine may be contributing to the antidepressive effect.

How long can a person stay awake? In 1965, Randy Gardner stayed awake for 11 days as part of an experiment.


If you are struggling with sleep deprivation symptoms, you should talk to your physician about treatment options.

8 Reasons Why My Dad Is the Most Important Man In My Life

Forever my number one guy.

Growing up, there's been one consistent man I can always count on, my father. In any aspect of my life, my dad has always been there, showing me unconditional love and respect every day. No matter what, I know that my dad will always be the most important man in my life for many reasons.

1. He has always been there.

Literally. From the day I was born until today, I have never not been able to count on my dad to be there for me, uplift me and be the best dad he can be.

2. He learned to adapt and suffer through girly trends to make me happy.

I'm sure when my dad was younger and pictured his future, he didn't think about the Barbie pretend pageants, dressing up as a princess, perfecting my pigtails and enduring other countless girly events. My dad never turned me down when I wanted to play a game, no matter what and was always willing to help me pick out cute outfits and do my hair before preschool.

3. He sends the cutest texts.

Random text messages since I have gotten my own cell phone have always come my way from my dad. Those randoms "I love you so much" and "I am so proud of you" never fail to make me smile, and I can always count on my dad for an adorable text message when I'm feeling down.

4. He taught me how to be brave.

When I needed to learn how to swim, he threw me in the pool. When I needed to learn how to ride a bike, he went alongside me and made sure I didn't fall too badly. When I needed to learn how to drive, he was there next to me, making sure I didn't crash.

5. He encourages me to best the best I can be.

My dad sees the best in me, no matter how much I fail. He's always there to support me and turn my failures into successes. He can sit on the phone with me for hours, talking future career stuff and listening to me lay out my future plans and goals. He wants the absolute best for me, and no is never an option, he is always willing to do whatever it takes to get me where I need to be.

6. He gets sentimental way too often, but it's cute.

Whether you're sitting down at the kitchen table, reminiscing about your childhood, or that one song comes on that your dad insists you will dance to together on your wedding day, your dad's emotions often come out in the cutest possible way, forever reminding you how loved you are.


7. He supports you, emotionally and financially.

Need to vent about a guy in your life that isn't treating you well? My dad is there. Need some extra cash to help fund spring break? He's there for that, too.

8. He shows me how I should be treated.

Yes, my dad treats me like a princess, and I don't expect every guy I meet to wait on me hand and foot, but I do expect respect, and that's exactly what my dad showed I deserve. From the way he loves, admires, and respects me, he shows me that there are guys out there who will one day come along and treat me like that. My dad always advises me to not put up with less than I deserve and assures me that the right guy will come along one day.

For these reasons and more, my dad will forever be my No. 1 man. I love you!

Being Sick In College Is A Real Struggle

Being sick in college is definitely not as fun as having a sick day in middle school or high school.

Something that I have had to deal with multiple times these past two semesters is being sick while in school. It can be a real pain especially depending on what type of sickness it is. I have had tonsillitis, mono, and I'm pretty sure I also had the flu.

Being at school and away from home can make being sick worse because there is nobody to take of you such as your parents. Another thing is having to make the decision to get the rest that your body needs in order to feel better or staying on top of your assignments to avoid falling behind. My parents will always tell me to get a good night's sleep so my body can feel better the next day. However, sometimes I will feel more stress if my work isn't getting done and I feel like I'm falling behind and leaving things to get done in the last minute.

Currently, I am sick now and the past few days haven't been easy, but I still attended all my classes so I wouldn't miss any material or assignments that were given. I usually end up feeling the worst at night when trying to fall asleep, and by that time the doctors are not present at the student health center. Even though my health is important I usually don't like taking too much time out of my day to go to the health center to see a doctor. Some days I don't really have much free time before the evening.

I don't believe I have been over-exerting myself, but I don't want to just stay in my bed all day and sleep, even though that may be what is best for me. Most professors will be understanding if I email them and provide them a doctor's note as well, but I also just got back from a conference where I had to miss two days of classes next week.

I have been trying to keep hydrated so that way my body can fight the sickness. Also, I have been told if you stay hydrated you can flush the virus out of your body quicker.

Eating can also be a pain when you have a sore throat, for the past couple of days I have tried to have some soup in order to help. Most meals I would have to force myself to eat something of substance in order to give my body some type of energy in order to get through the day. It's also never fun not being able to breathe out of your nostrils. If it wasn't my nose being stuffed, then it would be constantly runny so there was no winning that battle.

Looking back, I probably should have done a bit more work over spring break in order to get ahead in the case that something like this would happen. I wanted my break to be exactly that, a break. After not being home for a few months I just wanted some time off to relax.
