While her daughter was in preschool, Rebecca Spencer experienced something many parents and caregivers were familiar with: the power of the cut.
As a shortcut to your daughter's dizziness, grumpy or both at the same time.
Spencer, a neuroscientist specializing in Amherst University at the University of Massachusetts in the United States, wanted to explore what lies behind this anecdotal experience.
Or A lot of people realize that a cut is emotionally deregulation of a child, “he explains. 39 This has prompted us to ask ourselves a question: Do the niches really help to convey emotions? & # 39;
8 things you should know about sleep and the effects on your body
In general, scientific research has shown that sleep can help us understand emotions. In fact, it plays a key role in coding the information extracted from today's experiences, so it is essential to keep the memories.
And emotional memories are unique because of the way in which the amygdala activates the body: the emotional core of the brain.
Hatırla The activation of the Amygdala body is what allows you to remember the wedding day and the funeral of your family more than any working day, Sp says Spencer.
The amygdala body significantly labels these memories, so that they are processed longer during sleep and are repeated more often than any other insignificant memories.
As a result, emotionally important memories are easier to recover in the future.
However, by affecting how memories are processed, they can change the power they have.
Ina Sleep is especially effective when converting emotional memory,, says Elaina Bolinger, professor of emotion and sleep, at the University of Tuebingen, Germany.
In a recent study, Bolinger et al. Showed both negative and neutral images to children aged 8 to 11 years. Children showed their emotional reactions by choosing simple drawings of people.

Later, some children slept and others did not. The researchers checked the brain physiology through the electrodes in the next room.
The next morning the children saw the same images as well as some new ones. Compared with awake children, sleeping children had better control of their emotional reactions.
This research suggests that sleep can help crystallize emotional information and control how it feels. And this effect is quick.
"Most of the available research shows that a single night of sleep is already useful," says Bolinger. "It is useful for processing memories and is also important for emotional arrangements in general."
But not all dreams are the same.
Rapid eye movement (REM) sleep is associated with emotional memories, and more sleep of REM causes people to better evaluate others' intentions and remember emotional stories.
One theory points to the absence of noradrenaline in the stress hormone during REM sleep. The temporarily released brain from this hormone can process memories without stress.
Curious experience of clear dreams: Can you control what you are doing while you sleep?
Simon Durrant, head of the Sleep and Cognition Laboratory at the University of Lincoln, UK, highlights another aspect.
The prefrontal cortex is the most advanced part of the brain: as Durrant puts it, "the human urge to remain calm and not react immediately to things."
During awakening, this amygdala is the part that keeps his body under control and hence holds emotions. This connection is reduced during sleep.
"In a certain sense during REM sleep, the feeling is very common."
Why are we dreaming and why do the dreams repeat themselves?
However, Spencer believes that REM sleep plays an important role. Slow-wave sleep (SWS) is the first sleep phase that combines memories and is particularly effective when processing neutral memories.
Spencer's study suggests that the amount of SWS activity in sleep affects the way emotional memories are transformed.
Confectionery mainly consists of non-REM sleep. And a recent article by Spencer appears to be the first person to show that he contributes to the processing of emotional memory for children, not just to sleep.
Without drowsiness, children showed prejudice against sentimentality. They responded in a similar way to neutral stimuli and emotional stimuli.
In summary, if they do not, children become hypersensitive to emotional stimuli, because they ensure that they do not reinforce the emotional baggage of that day.
Spencer believes that somnolence has contributed to emotional processing, although not to the same extent. An adult has a more mature hippocampus and therefore has more ability to preserve memories. Failure to sleep does not cause them much harm.
However, this is only up to a point. Spencer's research on aging suggests that "as we grow older, we must unite more memories."
Interestingly, older adults show a bias against positive memories, whereas young adults tend to be negative.
Why would you get any less sleep?
This may be because children and adolescents focus on negative experiences, because they contain important information to learn: from the risk of fire to the risk of accepting a drink from a foreigner.
But towards the end of life, people give priority to the positive. In addition, people with less REM sleep, especially those with depression, are likely to sleep in such a way as to recover negative memories.
Sleep researchers also analyze the potential of some sleep conditions to treat posttraumatic stress disorder (PTSD).
One study demonstrates that a 24-hour follow-up of a traumatic experience makes these memories less painful in later days. For people with anxiety, sleep therapy can help them to remember that they have removed their fears.
In contrast, wakefulness therapy, in which people deliberately lack sleep, are spreading as a method to treat depression.
In some cases, insomnia may have a protective effect. Spencer noted that after a trauma, "the natural biological response under these conditions is to have insomnia."
For this reason, sometimes REM sleep deprivation may be good for the brain's ability to reinforce emotional memories.
Do you sleep a little when you sleep home?
"There is evidence that people with longer REM sleep tend to get more depressed," Durrant says. The expert believes this is due to the fact that a subset of depressed people are reuniting negative memories during REM sleep.
Is I don't think I've solved this problem, ğ he says.
But what is clear is that certain types of decision-making after sleep are partly due to the way in which sleep is regulating the whole vortex of emotions.
Bolinger explains this clearly: in general, "sleep helps you feel better".
