Have you ever feel fussy and dizzy? Maybe it was due to lack of sleep. Do not ever take for granted this! Lack of sleep can affect the sexual life, memory, health, appearance, and even make your body "stretch".
Here are 10 surprising things that happen due to lack of sleep:
1. Accident
Lack of sleep is one of the biggest disasters in the history of other nuclear accident at Three Mile Island in 1979, the biggest oil spill Exxon Valdez, Chernobyl nuclear crisis in 1986, and others.
Sounds excessive, but you should be aware of the lack of sleep also affects your safety every day on the road. Drowsiness can slow the time you are driving, the equivalent when you are drunk while driving.
A study conducted Safety Board The National Highway Traffic Americans shows that fatigue is a cause 100,000 car accidents and 1,500 deaths a year in the U.S.. The victim under the age of 25 years.
The same study showed that, if you lack sleep or have a low sleep quality, then it can cause accidents and injuries at work. In one study, workers who complained of excessive sleepiness during the day while working and injured vulnerable continually suffered the same accident while working.
2. Decreased concentration
Good sleep plays an important role in thinking and learning. Lack of sleep can affect many things. First, affect alertness, concentration, reasoning, and solving problems. This makes learning difficult and inefficient. Second, the cycle of sleep at night play a role in "strengthening" of memory in the mind. If you do not get enough sleep, so you will not be able to remember what you learned and experienced during the day.
3. Serious health problems
Sleep disorders and chronic sleep deprivation can bring your level of risk:
* Heart disease
* Heart attack
* Heart Failure
* Irregular heart rate
* High blood pressure
* Stroke
* Diabetes
According to some studies, 90 percent of people with insomnia, sleep disorder characterized by difficulty sleeping and waking up all night, also have similar health risks.
4. Decreased sex drive
The experts reported that poor sleep in men and women reduce the level of libido and boost sexual intercourse. This is due to depleted energy, drowsiness, and rising tension.
For men who suffer from sleep apnea (breathing problems that interfere with sleep) sleep deprivation causes sexual desire doldrums. A study published in the Journal of Clinical Endocrinology & Metabolism in 2002 showed that almost all people who suffer from sleep apnea have lower levels of testosterone. Nearly half of those who suffer from severe sleep apnea have a low testosterone level at night.
5. Cause depression
In the 1997 study, researchers from the University of Pennsylvania reported that people who sleep less than 5 hours per day for seven days cause 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 a strong relationship with depression. In a study in 2007 involving 10,000 people revealed that people with insomnia to 5 times more susceptible to depression. In fact, insomnia is often one of the first symptoms of depression.
Insomnia and appetite due to depression are related. Sleep deprivation worsen the symptoms of depression and depression makes you more difficult to sleep. The plus side, a good sleep pattern can help treat depression.
6. Affect skin health
Most people who have pale skin and black eye after a night of little sleep. This condition is true because of chronic sleep deprivation can lead to dull skin, fine lines on 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 collagen or proteins that make skin silky smooth and elastic.
Lack of sleep also can cause the body to produce less growth hormone. When we were young, human growth hormone growth. In this case, the hormone that helps 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. Forgetful
Do not want to forget the best memories in your life? Try sleeping good. In 2009, researchers from the United States and France found that brain events are called sharp wave ripples are responsible for strengthening the memory in the brain. This event also transfer information from the hippocampus to neocortex in the brain, where long-term memory storage. Sharp wave ripples occur mostly during sleep.
8. Body to be "stretch"
If you ignore the effects of sleep deprivation, so be prepared with the threat of being overweight. Lack of sleep is associated with increased hunger and appetite, and possibly could be obese. According to a 2004 study, nearly 30 percent of those who slept less than six hours a day tend to be fatter than those who slept seven to nine hours a day.
Recent research focused on the relationship between sleep and peptides that regulate appetite. Ghrelin stimulates hunger and leptin to signal satiety to the brain and stimulating appetite. Short sleep time is associated with decreased leptin and increased ghrelin.
Lack of sleep not only stimulates the appetite. It also stimulates the desire to eat fatty foods and foods high in carbohydrates. The ongoing research is conducted to investigate whether sleep is eligible to be a standard part of a weight loss program.
9. Increased risk of death
In the Whitehall study-2, British researchers discovered how sleep patterns affect the mortality rate of more than 10,000 British civil servants over the past two decades. According to the research that was published in 2007, those who sleep less than 5-7 hours a day increases the risk of death due to various factors. Even the lack of sleep increased two-fold risk of death from cardiovascular disease.
10. Destructive evaluation, especially regarding sleep
Lack of sleep can affect the interpretation of events. The body is weak so we can not judge a situation accurately and wisely. In the faster-paced world of today, sleep habits become a kind of badge of honor. Specialists on the bed said, You are wrong if you think okay despite the lack of sleep because no matter where you work in any profession, will be a big problem if you can not judge something better.
"Studies show that over time, those who slept for 6 hours, not 7 or 8 hours a day, began to feel that they have adapted to the lack of sleep. They're used to it," says Gehrman.
"But if you see the results of tests of mental alertness and performance, their value continues to deteriorate. It explains how lack of sleep affect our daily activities."
