Often forget things and do not know why? Have trouble concentrating? Probably not enough sleep. Lack of sleep can you stop to think clearly and keep your emotions under control. Excessive lack of sleep can affect work performance, social relationships and lead to psychological problems such as anxiety or depression.
Why people do not put value on sleep
Most people who do not sleep enough are unable to recognize how it affected their mental health. Many believe that sleep is a luxury, a little pampering. They admit however that they feel better when they sleep well all night and that they feel worse when you do not. In fact, it is no secret that sleep improves memory and learning and understanding power.
"When sleep is like you put some energy in the bank," explains Dr. Barry Krakow from Maimonides Sleep Arts and Sciences, quoted by WebMD. Sleep, "literally the body repair at the cellular level. Without sleep can not do what you have proposed, or physically or mentally."
Recovery sleep is sometimes more challenging than we can imagine. If less than six hours sleep per night for a week, for example, have recovered about one night of sleep, too much to address a few extra hours of sleep over the weekend.
Effects of chronic fatigue
People who do not sleep enough frequently complain of dizziness. Here are three cases:
1. Lack of sleep slows the thinking process. Scientists who analyzed it found that sleep deprivation leads to reduced capacity of attention and concentration, and the more difficult to concentrate and pay attention to certain activities even feel more confused. All these affect the ability to perform tasks that call for a logic and complex trial.
Also, people who sleep poorly may have difficulties in taking decisions, because it is more difficult to assess the situation and choose appropriate behavior.
2. Excessive lack of sleep affects memory. Memory relies on a series of nerve connections, which they recover and harden during sleep. "Sleep is the experience and knowledge gained during the day to be stored in short-term memory," explains Dr. Avelino Verceles, College of Medicine assistant professor at the University of Maryland.
In fact, it appears that each phase of sleep has a well defined role in the consolidation of new information.
If you are sleepy, it is more likely to forget things. Inability to concentrate due to lack of sleep weakens as even more memory. If you fail to focus on something, it will not be stored in short-term memory and hence no long-term memory.
3. Lack of sleep makes learning more difficult. insufficient sleep affects learning in two ways. Becomes more difficult to assimilate information, because you can not focus, therefore learning becomes ineffective. Also, memory is impaired, which is essential in learning. In children, lack of sleep can also lead to hyperactivity.
Lack of sleep increases during the reaction, which is crucial when driving or perform other activities requiring reaction speed. Some statistics show that almost 20% of U.S. traffic accidents occur due to driver fatigue. Drowsy driving can be as dangerous as drunk.
In addition, insufficient sleep can significantly affect mood. May cause irritability, anger, and may reduce the ability to handle stress. Tired people are more likely to cause traffic jams and create conflicts. Also less likely that people who sleep less to do enough exercise, eat healthy or to engage in relaxing activities.
Fatigue increases the risk of depression. A 2005 study by researchers at the University of North Texas found that people with insomnia are 10% more likely to develop a form of depression and 17 times more likely to be sick of anxiety than those who have a healthy sleep.
Sleep deprivation and depression are so closely related that experts can not say with certainty that never came first. "Sleep and mood influence each other," says Professor Verceles. "It's not unusual for people who do not sleep enough to suffer from depression, not for people who suffer from depression do not sleep enough."
As the number of hours of sleep needed each varies from person to person, experts say the way we feel is the best indicator. "I should feel sleepy when you wake up," explains Professor Verceles. "You should be energetic throughout the day and to feel more tired as they close at the usual bedtime.
