Negative Impact of Sleep Deprivation Due

You ever feel moody and dizzy? Maybe it's due to lack of sleep. Do not ever underestimate this situation! Lack of sleep can affect your sex life, memory, health, appearance, and even make your body "stretchy".
Here are 10 surprising things that happen due to lack of sleep:
1. AccidentSleep deprivation is one of the biggest disasters in the history of factors other than nuclear accidents at Three Mile Island in 1979, the biggest oil spill Exxon Valdez, Chernobyl nuclear crisis in 1986, and others.
Sounds excessive, but you must realize lack of sleep also affects your safety every day on the road. Drowsiness can slow down your time driving, which is equivalent when you are drunk while driving.
A study conducted Safety Institute National Highway Traffic Americans showed that fatigue is a cause 100,000 car accidents and 1,500 deaths a year in the U.S.. The victim was a person under the age of 25 years.
The same study shows, if you lack sleep or have a low sleep quality, then it can cause accidents and injuries at work. In one study, workers who complain of excessive sleepiness during the day are vulnerable injured at work and constantly experience the same accident at work.
2. Concentrations decreasedA good sleep plays an important role in thinking and learning. Lack of sleep can affect many things. First, interfering with alertness, concentration, reasoning, and problem-solving. This makes learning difficult and inefficient. Secondly, the sleep cycle at night play a role in "strengthening" the memory in mind. If not enough sleep, then you will not be able to remember what you learned and experienced during the day.
3. Serious health problemsSleep disorders and chronic sleep deprivation stage can take you to the risk:
* Heart disease* Heart attack* Heart failure* Irregular heartbeat* High blood pressure* Stroke* Diabetes
According to some studies, 90 percent of people with insomnia, sleep disorder characterized by trouble falling asleep and stay awake all night-are also experiencing similar health risks.
4. Decreased sex driveThe experts reported, lack of sleep in men and women reduce libido and sexual drive. This is due to depleted energy, drowsiness, and rising tension.
For men who suffer from sleep apnea (breathing problems during sleep disturbing) lack of sleep cause sexual arousal sluggish. A study published in the Journal of Clinical Endocrinology & Metabolism in 2002 showed, almost all people who suffer from sleep apnea have lower testosterone levels. Nearly half of people who suffer from severe sleep apnea have a low testosterone level at night.
5. Causes depressionIn a 1997 study, researchers from the University of Pennsylvania reported that people who sleep less than 5 hours per day for seven days led to stress, anger, sadness, and mental fatigue. In addition, lack of sleep and sleep disorders can cause symptoms of depression.
The most common sleep disorder is insomnia, which has strong links with depression. In a study in 2007 involving 10,000 people revealed that people with insomnia 5 times more prone to depression. In fact, insomnia is often one of the first symptoms of depression.
Insomnia and no appetite due to depression are related. Sleep deprivation exacerbates symptoms of depression and depression makes you more difficult to sleep. On the positive side, a good sleep pattern can help treat depression.
6. Affect skin healthMost people have pale skin and puffy eyes after a night of sleep deprivation. The situation is completely due to a chronic lack of sleep can lead to dull skin, fine lines on the face, and dark circles under the eyes.
If you are not getting enough sleep, your body release more stress hormones or cortisol. In excessive amounts, cortisol can break down skin collagen or proteins that make the skin smooth and elastic.
Lack of sleep also can cause the body to release less growth hormone. When we were young, human growth hormones to encourage growth. In this case, these hormones help increase muscle mass, skin thicken, and strengthen bones.
"This occurs when the body is sleeping soundly-which we call slow wave sleep (SWS)-growth hormone is released," said Phil Gehrman, PhD, CBSM, Assistant Professor of Psychiatry and Clinical Director of Behavioral Sleep Medicine Program University of Pennsylvania, Philadelphia.
7. ForgetfulDo not want to forget with the best memories in your life? Try to multiply sleep. In 2009, researchers from America and France found that brain events are called sharp wave ripples is responsible for strengthening the memory in the brain. This event also transfer information from the hippocampus to the neocortex in the brain, where long-term memories are stored. Sharp wave ripples occur mostly during sleep.
8. Body to be "stretched"If you ignore the effects of sleep deprivation, so be prepared with the threat of being overweight. Sleep deprivation is associated with increased hunger and appetite, and likely to become obese. According to a 2004 study, nearly 30 percent of the people who sleep less than six hours a day tend to be fatter than those who slept seven to nine hours a day.
Recent research has focused on the relationship between sleep and peptides that regulate appetite. Ghrelin stimulates hunger and leptin signals satiety to the brain and stimulates the appetite. Short sleep time is associated with decreased leptin and an increase in ghrelin.
Lack of sleep not only stimulates the appetite. It also stimulates the desire to eat fatty foods and foods high in carbohydrates. Ongoing research conducted to investigate whether adequate sleep should be part of the standard weight-loss program.
9. Increase the risk of deathIn the Whitehall study of the 2nd, British researchers discover how sleep patterns affect mortality rate of more than 10,000 British civil servants over the past two decades. Based on research published in 2007, those who have been sleeping less than 5-7 hours a day increased the risk of death due to various factors. Even the lack of sleep increased two-fold risk of death from cardiovascular disease.
10. Particularly damaging assessment of sleepLack of sleep can affect the interpretation of events. State's limp body to make we can not judge the situation accurately and wisely. You who sleep less are particularly vulnerable to bad judgments when it comes time to assess what is lacking of something.
In a fast paced world today, sleep habits become a kind of badge of honor. Specialists say about sleep, you're wrong if you think you are fine despite lack of sleep because no matter where you work in any profession, will be a big problem if you can not judge something well.
"Studies show that from time to time, people who slept for 6 hours, instead of 7 or 8 hours a day, began to feel that they have adapted to less sleep state. They're used to it, "says Gehrman.
"But if you look at the results of test performance and mental alertness, their value continues to deteriorate. That explains how your sleep deprivation interfere with our daily activities. "
