Power of the capsule to help us to control our feelings


When her daughter was in the pre-school, Rebecca Spencer knew something that many parents and carers knew: sacred power.

Without swimming, her daughter was bare, bare, or the two at the same time.

Spencer, a neuroscientist specialist who specializes in sleeping at Amherst Massachusetts University, in the United States, is to explore what is behind this amazing experience.

"Many people realize that a child without restrictions is emotionally controlled," he says. "Give us a question to ourselves:" Are napsan really helpful to handle feelings? ""

8 things you should know about sleeping and the effects on your body

Scientific research has shown that, as a result, sleeping helps us to make sense of feelings. Indeed, it has an important part in encoding the information from day-to-day experience, and so it is essential to preserve the memories.

And the emotional memories are distinctive because of the way in which they function: amygdala body: the emotional heart of the brain.

"Spencer says is the functioning of an amygdala body that helps you to remember your wedding day and funeral for parents more than any other day of work," said Spencer.

The amygdala corpse describes these memories as a meaning, so that they are longer treated and treated; happening more than other wild memories.

It is the result that an emotional memory is important in the future.

But by influencing how reminiscences are handled, the dream can also change their power.

"Sleep is especially effective when it comes to emotional change," said Elaina Bolinger, a specialist in mood and sleep at the University of Tuebingen, Germany.

In a recent study, Bolinger and his colleagues showed different and neutral drawings for children aged between 8 and 11 years old. Their children showed their emotional response by " choosing simple images of people.

5 tips for good, long and deep sleeping

Later on, some of the children were sleeping and others did not. The researchers were in control of her & # 39; brain biology through electrons from the next room.

The next morning, the children saw the same images, as well as new ones. And compared to the children who stayed awake, their children who were awake, better sleep and control their emotional responses.

This search shows that sleeping is at # 39; help you to retrieve emotional and emotional information. controlling how it implies us to & # 39; feeling. And this is happening quickly.

"Much of the current research shows that one night of sleep is already useful," said Bolinger. "It's useful for memory processing, and it is also important for general emotional management."

But not every dream is the same.

Types of sleep

Sleep-acting (REM) is associated with emotional memories, and if more sleeping REM causes people to better evaluate the intentions of others and remember emotional stories.

One theory indicates that the hormone stressed noradrenaline in REM sleeping. Being released recently from this hormone, the brain can produce processless processes.

The stunning dreams of the amazing knowledge: can you control what you do long & # 39; as you sleep

Simon Durrant, head of the Laboratory of Sleeping and Science at the University of Lincoln, in England, marks another side.

The prefrontal lagoon is the most prominent part of the brain: that is where Durrant says, "the person is motivated to keep calm and not, deal with things right away. "

At the time of awaking, this is the part that is </ p> <p> control the body of codigo and, therefore, the feelings. During sleep, that connection is reduced.

"In a special way, when REM is sleeping, the mind is going on."

Why are we dreaming and why dreams come from? going again?

But Spencer believes that there is also an important role in non-REM sleeping. Slow-wave sleeping (SWS) is a first phase of sleep that is a Confirmation of memory, and is particularly effective when editing neutral memories.

Spencer's research shows that the level of SWS activity during sleeping time; influencing how the emotional memories are transformed.

Naps is a non-REM sleeping. And a recent article written by Spencer is the first one that shows that news, and not only in the nighttime sleep, contributes to interesting childhood memory processing.

Without a collision, children showed a sense of expression. With nap, they also responded to neutral incentives and emotional incentives.

In a summary, he / she makes sure that "if they do not stretch, their children will be attractive to emotional stimulation," because they have not confirmed bags emotional that day.

Spencer believes that news also contributes to emotional behavior in adults, although not just as high. An adult has a hypocross more advanced and, thus, more ability to preserve memorials. Sleep does not harm them.

However, that's just up to a point. Spencer's research is related to a & # 39; getting older says "we need to consolidate memories more often when we get older."

Interestingly, older adults show distressing memory that sucks good, long and full memory; Are young adults closer to negatives

Why not be asleep as slow as your life is

This may be due to the fact that children and adolescents are in a position; Focusing on negative experiences because they have basic knowledge to learn: from fire hazards to the dangers of adopting a stranger drink.

But in terms of end of life, people are prioritizing what is positive. They are also less than REM sleep, the type of sleep that is likely to save negative memorials, especially in people with depression.


Casting researchers also investigate the ability of some special sleep to deal with stress disorder after disturbance (PTSD).

One study indicates sleeping within 24 hours of poor experience; making these memories not so sad afterwards. For people with worry, sleeping medicine can remind them that they have scared their fear.

On the other hand, there is a protection of immunity – in which people are consumed of a single thing – a & # 39; distributed as a means of dealing with depression.

In some cases insomnia can have a protection effect. Spencer says, "after trauma," is the insomnia in the natural biological response of those situations. "

So, sometimes, it can be good that the lack of REM wear adversely affects the brain's ability to reinforce emotional memories.

The home-based home test will know if you're sleeping

"There is evidence that REM sleepers are longer likely to be worse," said Durrant. The expert believes that this is because a sub-group of people with dementia is reinforcing negative reminiscences in REM sleeping.

"I do not think I can settle this case," he says about the clinical demands that may be of sleep and healing medicine.

But what is clear that some decisions come after sleeping, partly due to the way in which sleeping is happening; rule all of those feelings.

Bolinger clearly explains: in general, "sleeping helps you to feel better".

At the end, the best rash for a broken heart or fast mind may be the proportion.
