Good night and its rituals

It is known that children do not like to go to sleep. They are capable of suddenly collapsing half-heartedly, but if they are told it is time for bed they either tergiversate, make a thousand excuses, or, when they are particularly tired, seem to engage in a real battle against sleep (and also account for us!), with all deliveries on the tantrums, of whining, etc. But why all this? Is it just a matter of irritability, of bad manners, or does this difficulty have a deeper meaning that education should take into account?

Why don’t babies want to sleep?

Children live in the immediate, the younger they are the more the future ( and by future we also mean the morning after or the after afternoon nap) for them is something extremely vague and nebulous. Falling asleep is like leaving, like dying: losing everything, leaving objects and landmarks behind and sinking into a kind of “black hole” of unawareness. It is precisely this kind of perception that leads them to struggle against sleep experienced almost as a danger and not as a restorative embrace. The goal is not only that the child falls asleep but also that from this fundamental function that is repeated and will be repeated every day and several times a day the child can derive , alongside the good habit, a security of self, based on trust and constancy (of objects, affections, circumstances).

How to promote sleep

For as long as the world has been alive, specific ways have been developed to help children fall asleep: just think of lullabies, the act of rocking, the cradles named after that movement, the habit of telling or reading a story, to the favorite puppet (or blankie or rag), etc. Since time immemorial, to go to sleep, lights are dimmed, noises are dampened, that is, we try to create a situation as of “decompression” in which “exciting” sensory stimuli become more and more distant to make way for a reassuring, repetitive and fading rhythmicity.

All of these behaviors serve the function of promoting relaxation, containing the child, and accompanying the child on a potentially anxiety-inducing path of “abandonment.” It is important that this delicate moment, which among other things marks that essential rhythm of life given by the alternation of wakefulness and sleep, be “ritualized“, that is, have its own canvas (for each child and for each stage of growth, his own) that enshrines the meaning of the moment, its preparation, its unfolding; that contains and reassures the child, never making him feel at the mercy of unknown events; that provides him with awareness of what is happening to him and allows him, precisely by virtue of the space and time dedicated, to connect today’s “bedtime” with yesterday’s and with tomorrow’s awakening.

Endless can be the rituals of the Good Night, rituals made of play, of creativity, of rules, but all of them, like any self-respecting ritual, must be solemnized (that is, they must have their own consistency and constancy), shared among several people (the child and those accompanying him, even if simply reminding him that it is time to sleep), have meaning and purpose.

Avoid sleep caused only by exhaustion

Otherwise, when children are only able to fall asleep if they are “exhausted,” watching television on the sofa, in their parents’ bed or alone in their bedroom, they lose the ability to gain awareness of this function, that is, to enter the world of sleep confidently and voluntarily. Instead, they fall” into it as if into a net without any preparation and basically without any accompaniment. Parents, who are supposed to provide the time, place and mode, instead seem in many cases to passively and laboriously point to their children’s “battery exhaustion,” becoming victims themselves of this confusing mechanism. The principle of all full all empty is substituted for the ability to regulate and pace energy.

So many sleep disorders in children and, especially, adolescents stem from precisely this initial failure to gain awareness, autonomy, and pleasure in regulating rhythms and needs.

Sleep and Memory: Memory in the depth of sleep

The brain, even when we sleep, works. Various research now agrees in assigning the sleeping brain a central role in memory fixation and thus in learning. The demonstration of this apparent paradox comes from research
on the “nap”: volunteers tested for mnemonic retrieval of a list of words learned, whether, between learning
of the list and recovery, they had interjected a nap of about ninety minutes, remembered more words than those who had not slept. This phenomenon has even been found in very young children, as shown by a group of psychologists from Germany’s Ruhr University, who recently published in PNAS a study conducted on children between 6 and 12 months of age. Children’s brains at this age have already developed a strong imitative capacity. The researchers used this skill to test whether napping could improve memorization of simple actions with objects. Children who had slept more than half an hour, after ‘exposure to object manipulation, were more capable, in reproducing these actions, than those who had slept less than half an hour.
The most surprising data, however, come from studies of adults. In fact, the paradox is that memory consolidation, a purely cognitive and therefore demanding activity, occurs when we are in the depths of deep sleep, when the brain machine is at its lowest oxygen consumption, blood flow is slow and the electroencephalogram shows large, slow and very slow waves.It is known that during sleep, our brain activity is highly variable: cycles alternate, of about an hour and a half each, containing phases dominated by slow and very slow electric waves and instead phases characterized by mixed, fast-dominated waves. The latter is called the REM (Rapid Eye Movement ) phase because fast waves are accompanied by rapid eye movements. At this stage we have very detailed and consistent dreams , which have an easier time being remembered. At the electroencephalus gramma, the brain shows a profile very similar to that of wakefulness. Therefore, for a long time REM phase was thought to be the one most related to nighttime cognitive activity. Instead, it is now clear that it is the slow and ultralow wave phase, called Slow Wave Sleep, which is part of the broader Non -REM phase, that is implicated in nighttime memorization. Bjorn Rasch and Jan Born, neuroscientists at the University of Zurich, in an extensive review in Physiological Review, document that exposure to an odor, during a cognitive learning task, prompts memory consolidation only if the same people are re-exposed to the same odor while in the deep sleep stage and not REM sleep. But what are the hypothesized brain mechanisms?
Fixation of a memory is a process that requires the cooperation of two brain areas: the cortex and the hippocampus. The former fixes attention on the object to be memorized, frames it, gives it a code and then transfers this initial encoding to the hippocampus, which will consolidate the trace and then transfer it back to the cortex, where it can be integrated into the various drawers of our memory and remain available for further recall. In this dialogue, the two areas go at different speeds: the cortex is characterized by fast waves and theta waves, which are relatively slow waves, have a rhythm (4 -8 Herz) but are more than twice as fast as the slow waves, the deltas (1-4 Herz), which instead dominate the hippocampus and the deep phase of sleep. During wakefulness then, the first phase of memorization would occur in the sign of theta waves, while during deep sleep, the hippocampus would consolidate the memory with slow and ultralow activity (less than 1 Herz).

What evidence do we have for this explanation? The application of a transcranial current (absolutely painless operation) with delta frequency, on the area of the head that corresponds to the prefrontal cortex during the first stage of sleep, increases the memory of an exercise done before sleep. If a theta frequency is administered instead, the memory is suppressed. But conversely, if a theta frequency is administered during wakefulness, when one is engaged in learning, memory is improved. Further evidence came on March 15 when a group of Austrian neuroscientists hadimproved in the Journal of Cognitive Neurosciencethat theta activity during learning is directly related to the ability to remember after a night’s sleep. In essence, say the researchers,during slow-wave sleep, the hippocampus selects memories to save and those to throw away and does so by following a label that has been affixed to them during wakefulness, the theta label. Finally, there is another type of

Sleep and Memory

And that is the immune one. Volunteers who received a single dose of hepatitis A vaccine, if they did not sleep the night after the vaccine, the antibody level (indicating vaccination efficiency), checked after four weeks, is much lower than that of their colleagues who slept .

The arms and legs of memory

It is well known that we Italians are good communicators and use gestures a lot to emphasize or complete a message. This characteristic, which might appear to be a simple trait of the Latin costume, more expansive and physical than that of the global north, now acquires a new dimension in the light of cognitive neuroscience. In fact, gestures, in addition to playing a communicative role, also play a role in ‘cognitive processing and memory. We have a body of evidence showing that, when recalling an event, gesticulation can promote recall of details better than when gesticulation is interdicted. In addition, gesticulation, prior to recall of previously learned words, helps recall performance. Other studies have documented an effect of gesticulation on working memory. This renewed interest on the relationship between body, cognition and memory has important clinical basis. Indeed, it has long been known that neurological and psychiatric disorders often go hand in hand with motor impairments and, conversely, that motor disorders go hand in hand with psychiatric impairments.
A typical feature of depression is impaired memory and motor slowing, just as motor impairments are common in psychotic and anxiety disorders. Conversely, Parkinson’s, which is the typical disease of the basal ganglia motor system, frequently presents with depressive disorders and/or worsening of cognitive performance and memory. Finally, it is well established by numerous controlled clinical trials that structured exercise has positive effects on major depression and anxiety disorders, dementia, and other neurodegenerative disorders. A recent randomized controlled trial published in Neurology by an interdisciplinary group at the University of Iowa documented that aerobic activity improves not only fitness, motor function, and fatigue, but also mood, cognition, and memory in people with Parkinson’s disease. Extensive animal and human research has documented that physical activity induces the release in the brain of three neurotransmitters critical for memory, such as dopamine, serot onin, and norepinephrine . At the same time, cannabinoids and brain growth and plasticity factors (IGF-1) put into the circulatory stream by muscle contraction reach the brain. One finding established by human research is the physical activity-induced increase in Brain-Derived Nerve Factor (BDNF), an increase that corresponds to improved memory retrieval capacity.

The secret to perfect sleep: body temperature

The benefits of sleep are now widely recognized, both for the body but especially for our minds. One of the most common problems, however, for humans, which negatively affects our health, is in fact that of not getting enough sleep or, at any rate, not properly. So what is the secret to resting well and regenerating our body at its best during the sleeping hours? One answer comes to us from a recent and very interesting international study that also involved the Molinette Hospital of the City of Health in Turin, as well as a long list of European and U.S. research institutions (Center for Chronobiology, Basel University, Sleep Medicine Center, University of Berlin, Center for Sleep and Circadian Biology, Northwestern University Chicago). According to the study, more than medications and therapies, the temperature of our body turns out to be crucial for proper sleep. In fact, by lowering the body’s internal temperature, as is the case for some animals during hibernation, sleep results in deeper and more restful sleep.

 

The innovative mattress

The research was developed by analyzing the sleep of 60 volunteers, all healthy and free of sleep problems, either on ordinary mattresses ( low heat capacity) or on A new and innovative mattress (high heat capacity), a polyurethane compound with a heat capacity 10 times the norm, capable of dispersing body heat into the environment. In the last case, there was a considerable increase in slow-wave sleep, which is the deepest phase of non-REM sleep, in which the main physiological and metabolic processes important for our body’s well-being take place. This results in a significant reduction in sleep-related disorders, which are guilty of significantly reducing our cognitive performance (such as attention and memory) and physical performance (causing persistent fatigue and exhaustion).

 

As Molinette Hospital points out, “The secret lies in a high-tech material that covers the mattress and draws heat away from the body, similar to what happens in bears or marmots during winter hibernation. In short, colder body, deeper sleep.” The study, which is being further investigated and refined, may open up new scenarios in the field of sleep modulation, especIially in the pharmacological field.

Going to school an hour later to learn more

Do sleepers catch no fish? Perhaps, but he can get better grades in school for the same amount of effort and hours spent on books during the day.

Reporting this are the results of a studio conducted by researchers at the University of Washington, which evaluated the effects of a measure introduced in high schools in the Seattle (U.S.) district for the purpose of granting children the ability to get a little more sleep in the morning and bring the average number of hours devoted to the night’s rest to the 8-10 hours per night recommended for adolescents by the American Association of Pediatricians (AAP, American Academy of Pediatrics).

Starting from the consideration that the sleep is essential not only to rest the body and mind, but also to promote the reorganization and consolidation of information assimilated during the day, U.S. experts thought that Postpone the time of entry to school by about one hour, from 7:50 a.m. to 8:45 a.m., could have favorable effects on intellectual performance and performance in study.

In fact, the outcomes recorded by comparing the grades obtained by students attending the schools involved in the trial at the same times of the year, before and after the change in the entrance time, confirmed this hypothesis.

Moreover, achieving better school results and taking advantage of a more alert and receptive mind throughout the day took very little. The 55-minute forward shift in the time of school entry was, in fact, matched by an average increase in the time children slept by 34 minutes, bringing the overall nightly sleep duration on school-attendance days from an average of 6 hours 50 minutes to 7 hours 24 minutes, with no significant changes in bedtimes or other changes in sleep-wake rhythms on weekends.

Although the average sleep duration remained below the period recommended by theAmerican Academy of Pediatrics, as well as on school performance, the measure of the Seattle district has also resulted in a significant reduction in the number of late admissions and school absenteeism, especially in favor of students from disadvantaged backgrounds.

The overall effects recorded by the University of Washington researchers have prompted many experts to urge the heads of educational institutions to consider postponing the start time of classes in all upper secondary schools. But wouldn’t it be less complicated to get teenagers used to going to bed earlier in the evening?

Perhaps, but in light of current knowledge it may be more difficult for children to get used to anticipating falling asleep, and the overall effects of this type of intervention may not be particularly favorable. During adolescence, in fact, the internal biological clock tends to be “shifted forward” from that of adults, making teens more likely to fall asleep a little later in the evening and wake up a little later in the morning. Keeping the time of kids’ spontaneous falling asleep constant and giving them even only 30-40 minutes more sleep in the morning would, therefore, seem to be the most “physiological” solution and characterized by the best psychophysical and intellectual outcomes.

Fibromyalgia, a real puzzle of modern medicine

Fibromyalgia syndrome, more commonly known as fibromyalgia, represents a real enigma, as recently pointed out by some authors (Häuser et al, 2019). Over the past three decades, the acceptance, although not always unanimous, of the diagnosis of fibromyalgia has led to an unwarranted increase in the number of cases; in fact, guidelines accepted by the international scientific community are necessary for a correct diagnosis.

The most important complaint is chronic widespread pain along with two so-called major symptoms, fatigue and unrestorative sleep. In the 2016 review (Wolfe et al, 2016), in addition to the above criteria, the need for the patient to undergo careful medical examinations, including a history and objective assessment, was noted. Specifically, this revision combines medical criteria with those on patient-administered questionnaires, minimizes misclassification of regional pain disorders, and eliminates previous confusing recommendations regarding diagnostic exclusions. The importance of self-assessment forms in the clinical diagnosis of the individual patient, on which the previous criteria were based, is also reduced.

Although at present there are no specific laboratory tests for the diagnosis of this syndrome, careful medical examinations, especially in the fields of rheumatology and neurology, and the performance of instrumental and laboratory investigations are essential to rule out other pathologies.

Improving sleep with a smartphone or portable kit is now possible

A cutting-edge kit that helps analyze an individual’s microbiome may provide insight into why some people sleep poorly: that’s one of the new technologies that were unveiled at the Consumer Digital Association 2019 Digital Health Summit in Las Vegas, developed for the purpose of improving sleep.

It is not easy to give the doctor objective information about sleep quality or to explain why you have difficulty having deep sleep-it is a complicated problem to describe and solve.

Using the kit, consumers send a stool sample to a laboratory that, using special metagenomic technology, is able to assess the presence of different bacteria in the gut.

In addition to the effect of microorganisms on gluten sensitivity, inflammation, lactose intolerance, weight and metabolism, the analysis examines the levels of bacteria that produce certain neurotransmitters involved in natural sleep rhythms, such as serotonin and gamma-aminobutyric acid (GABA).

The report generated by the microbiome analysis provides information on ways in which diet and lifestyle can help change the bacterial composition of the gut. A second test is recommended to verify the effectiveness of the interventions.

Another technology presented at the summit makes it possible to assess sleep quality. It is in this case a App which can tell whether the user is in a waking, light sleep, deep sleep or REM sleep state: simply place your smartphone on the bedside table to detect, every 30 seconds, the radio frequency and low-power energy emitted by the body. An algorithm built into the App generates a score from 0 to 100 to indicate a person’s sleep quality-the data can provide doctors and patients with objective information.

Again, the instrument not only measures sleep quality but also offers breathing techniques for relaxation and provides personalized advice; it also has a smart alarm clock that sounds during the light sleep phase, when waking up is less traumatic.

According to Daniel Kraft, who works in medicine and neuroscience at Singularity University, an organization dedicated to technology development, these are examples of the kind of tools that will increasingly allow us to affect not only sleep, but different aspects of our health: “Insights into the microbiome, glucose monitoring, metabolic data from respiration, and much more, detectable with a simple handheld device…the combination of all of this gives us new ways to get detailed information. We will be able to use these tools to track not only vital signs, but also behaviors, providing help to change them and make them healthier.”

Too much stress and too little sleep enemies of the heart

Several studies on this have already been done, but new evidence and quantification of the cardiovascular risk associated with excessive stress at work and at the sleep poor, taken singly or in combination, reported by the group coordinated by Karl-Heinz Ladwig of the German Research Centre for Environmental Health – Technical University in Munich, Germany, cannot go unnoticed, especially if you have high blood pressure.

Based on data obtained from the analysis of nearly 2,000 workers hypertensives between the ages of 25 and 65, in fact, those who are subjected to occupational stress and suffer from sleep disorders have a risk of death from cardiovascular causes as much as three times higher (+300%) than those who have relative job serenity and sleep well. And this is in the absence of aggravating risk factors such as metabolic syndrome, diabetes or known cardiovascular disease.

Even taken alone, work stress has anything but beneficial effects on the cardiovascular system, being associated with a 1.6-fold (+60%) increase in the risk of death from cardiovascular causes, while if fragmented and/or insufficient sleep is present in the absence of work stress, the increase in the risk of death from cardiovascular causes is 1.8-fold (+80%), compared to those affected by neither problem.

In absolute terms, over an 18-year follow-up period, work stress and inadequate sleep were associated with a risk of death from cardiovascular causes of 7.13 per thousand person-years compared with 3.05 per thousand person-years of those who are not stressed and sleep well, 4.99 per thousand person-years of those who are only stressed, and 5.95 per thousand person-years of those who sleep poorly without the work stress component.

The authors of the study point out that job stress is established in situations in which the worker is required to perform at a high level of performance with little or no decision-making power, that is, when in addition to being under pressure, one is also forced to carry out orders, without having a voice. Conversely, even a heavy workload can be irrelevant or beneficial to health if you can be in control of the situation and choose for yourself how to act.

Job stress is often associated with difficulties in fall asleep and to early awakenings that leave ample room for prolonged ruminations on the difficulties and frustrations of the day that has just passed or that will have to be faced after the alarm clock sounds, preventing the physiological stand-by that the cardiovascular system needs to stay healthy. If the situation involves short periods (days or weeks) it is not a big problem, but if it goes on for a long time (years) the matter changes dramatically, and the risks increase.

To avoid problems it is essential to act on both fronts, because while it is true that stress disrupts sleep it is equally true that unsatisfactory sleep makes one more nervous and prone to develop anxiety and stress. In particular, experts from the European Society of Cardiology (ESC) suggest:

  • Learn relaxation techniques and use them several times a day;
  • Follow a healthy lifestyle (balanced diet and regular physical activity);
  • Avoid smoking, alcohol and stimulants (excess caffeine, energy drinks, etc.);
  • Maintain regular rhythms and fall asleep and wake up at fixed times;
  • Identify personal strategies to reduce work stress;
  • Improve social relationships and increase leisure time;
  • If sleep does not improve, seek the help of a Sleep Medicine specialist;
  • If anxiety and stress are frankly excessive and difficult to control independently, seek psychological support.

Always tired? Here are the most common reasons

It will be the fault of spring, the heat of summer, the gloom of autumn or the cold of winter. Certainly, weather conditions and seasonal changes can contribute in no small way to making us feel tired, slowed down and down in tone. But the reasons behind exhaustion that is not commensurate with the actual daily physical and mental effort and that persists for more than a few days may also be related to the presence of disorders and diseases that require specific therapies. Therefore, protracted fatigue should always be reported to the doctor and deepened with some targeted examination. Unless it is simple sleep debt due to too short nights. A list of the main causes and some pointers to counteract them.

Good habits for good sleep

Even if one does not habitually suffer from insomnia, a few nights disturbed by discomfort or worry or spent completely blank for a variety of reasons can always happen. And the next day is usually very tiring to live through, especially if you have to work or study.
Here are some tips
of lifestyle to encourage peaceful and fulfilling nights and feel fresh and efficient during the day.

Sleep disorders in menopause

Many women complain of sleep disturbances in conjunction with menopause. Insomnia, pain syndromes, and snoring are the most frequent changes they experience, and the night often becomes long and tiring.

During the period of the so-called menopause, women experience a lot of stress of a hormonal nature, resulting in some very common complaints: sudden hot flashes, pressure changes, sudden mood changes, anxiety attacks, disturbed sleep, and insomnia.

Especially sleep disorders trigger a vicious cycle of nervousness, restlessness, and fatigue that go to the detriment of the female relational sphere. Let’s look at them in detail.

Restless leg syndrome

Patients who suffer from it report a sensation of discomfort in one or both legs (with involvement of the arms as well in severe cases) with an unavoidable need to move them, for example, if sitting too long. A feeling of restlessness that improves if the patient moves or massages the legs.

The disorder often occurs in the evening, when the patient is trying to fall asleep, and may also occur at night.
