A sleeping nap or short nap helps to make emotional information crystal and helps control how it feels.
When her daughter was in the past, Rebecca Spencer feels something that many parents and caretakers are aware of: tree power.
Without sleeping, her daughter was dizzy, upset, or both at once.
Spencer, a neuroscientist specializing in sleep at Massachusetts Amherst University in America, wants to check what's behind this extraordinary experience.
"Many people know that a sleepy child is emotionally free," she explains. "It asked us a question: 'Does the eyes really help in the process of emotions? & # 39;

Scientific research has already shown that sleep generally helps us to understand the meaning of emotions. In fact, they play an important role in coding information from day-to-day experiences, so it's essential to save memories.
And emotional memories are unique because they enable the Amigadala body: the emotional origin of the brain.
Spencer says, "The activity of Amgadala's body is that you can remember more than working on your wedding day and your parents' funeral the next day."
The Emigadala body labeled these memories as meaningful, so that they are processing for a long time during sleep and more frequently than other small memories.
The result is easy to recover emotionally important memories in the future.
But by the influence of how memories are processed, the power which they have the dream can also change.
Says Elena Bolinger, an emotional and sleep specialist at Tubingan University in Germany, "sleep is especially effective when it comes to emotional memory changes."
In a recent study, Bolangar and his colleagues showed negative and neutral images to children aged 8 to 11 years old. The children showed their emotional reaction by choosing children's easy drawings.

Later, some children slept and others did not. Researchers controlled their brain's physiology from electrodes in the next room.
The next morning, children watched similar images, as well as some new paintings. And compared to the children being awake, the children who slept have better control their emotional responses.
This research indicates that sleep helps to make emotional information cryptic and controls how we feel. And this effect happens quickly.
Bolinger says, "Most recent research suggests that a night of sleep is already useful." "It's useful to process memories, and it's also important for emotional regulation as well."
But not all dreams are the same.
Types of sleeping
Rapid eye movement (REM) is associated with sleeping emotional memories, and due to more REM sleep, people evaluate others' motives and remember emotional tales.
One theory REM points to the absence of stress hormone norendranolin during sleep. Temporarily releasing this hormone, the brain can process memories without stress.

Simon Durant, Head of Sleep and Cognition Laboratory at Lincoln University in England, has highlighted one other aspect.
The prefrontal cortex is the most developed part of the brain: it is where Durant says, "Human desire does not calm down and give immediate feedback on things."
During waking, this is the part that keeps the ammunition in control and therefore, keeps the emotions under control. During sleep, it reduces the connection.
"In certain sense, REMs are intense during sleep."
- Why do we dream and repeat dreams?
But Spencer believes that non-REM sleep also plays an important role. Slow Wave Sleep (SWS) is the first phase of sleep that integrates memories and is especially effective when processing neutral memories.
Spencer's research suggests that the amount of SWS activity during sleep is changed to emotional memories.
Nops have mainly non-REM sleep. And an article co-written by Spencer is the first article to show the naps, and not only the night's sleep, but also contributes to the emotional memory process in children.
Children without prejudice showed bias towards emotion. With nap, they gave a similar answer to a neutral stimulus and emotional stimulus.
In a nutshell, they assure that "if they do not sleep, children become addictive towards emotional stimuli", because they did not collect emotional goods that day.
Spencer believes that naps also contribute to an emotional process in adults, but not to the same extent. Adults are more mature hippocampus and therefore, there is more ability to save memories. Sleep does not hurt them much.
However, it is only up to one point. Spencer's research related to aging suggests that "we need to strengthen memories as often as we get older."
Interestingly, older adults show a positive attitude towards positive memories, while younger adults tend to negatively.
- Why would your life less sleep less?
This can be the reason because children and adolescents focus on negative experiences because they contain important information to be learned: the dangers of accepting a drink from the dangers of fire by the dangers of fire are risked.
But at the end of life people prefer positivism. They have low REM sleep, the type of sleep that most often preserve negative memories, especially in depressed people.
Sleep researchers are analyzing the possibility of some aspects of sleep for the treatment of post-traumatic stress disorder (PTSD).
One study suggests that sleeping within 24 hours of a traumatic experience makes memories less depressive in later days. Sleeping treatments for people with anxiety can help them remember that they are relieving their fears.
Conversely, awareness therapy – where people are deliberately deprived of sleep – spread as a method to treat depression.
In some cases insomnia can have a protective effect. Spencer notes that, after the shock, "those situations have a natural biological response insomnia."
Thus, sometimes it may be good that REM sleep reduces the ability to integrate the brain's emotional memories.

Durant says that "there is evidence that people who have been sleeping in the REM for a long time are more frustrated." Expert believes that this is because the subseat REM of depressed people re-unites negative memories during sleep.
"I do not think I will solve this problem," he says about possible clinical applications for sleep and awareness therapy.
But what is clear is that certain types of decisions are improved after sleep, partly due to which all the feelings of sleep emotions are controlled.
The bowler clearly explains: Generally, "sleep looks better for you".
In the end, the best way to get a broken heart or a cloudy mind can be a nap.
