Estudo sobre genes e sono

https://www.thesun.co.uk/news/8306330/depression-schizophrenia-risk-increase-night-owl/

Citando:
"They identified 351 genetic variations linked to being a “morning lark” or “night owl”.

Those with the most “night” variations were programmed to wake up to 25 minutes later.


And they were more likely to suffer frommental health issues.


But the boffins found no link between these genetic variations, sleep duration and sleep quality.


They also made no difference to the risk of developing type 2 diabetes or obesity.


Eye opening


It is thought the genes affect the effectiveness of the retina, which reacts to sunlight and “resets” the body clock each day."

Calculadora do sono para crianças

Calculadora da hora de deitar (online), desta vez para crianças:
https//www.web-blinds.com/resources/kids-sleep-calculator/

A lógica é a mesma do que para os adultos: 14/15 mins de lead time (tempo para adormecer) incluído nas contas e contas de maneira a que não se acorde a meio de ciclos do sono. Ciclos variáveis no caso das crianças: Por exemplo: 13 anos, ciclos de 60 mins; 16 anos, ciclos de 90.

Citando:
"Your child (13 years old) needs to wake at 7:45am, so they should go to bed at:
9:31pm or
10:31pm or
11:31pm
About the results:
All children’s body clocks are unique – some need 12 or more hours of sleep each night, others are content with much less.Happy mornings rely on sleeping patterns that fall in line with sleep cycles. And that’s where our sleep calculator helps.The Sleep Calculator for Kids works out the best time for your child to wake up by counting sleep cycles. Each cycle for a 13-year-old lasts around 60 minutes.Waking up mid-cycle can mean your child wakes up grumpy. So your results show wake-up times that are between cycles – that’s when you’re most likely to be greeted with a smile from your child.Most children take roughly 14 minutes to nod off (depending on the quality of the bedtime story). This time is included in your results."

Dizem que uma boa noite de sono vale milhões (equivale a sair a lotaria)...

Para isso é preciso não ser um grande camelo (para não ter peso na consciência, ou então ser um inconsciente), não ter stress a mais, não ter problemas respiratórios obstrutivos (que provoquem apneia), etc...

Alguém estudou que uma boa noite de sono vale mesmo milhões, e quantificou:

Good night's sleep boosts happiness as much as winning the lottery | Life | Life & Style | Express.co.uk

Citando:
"The study shows that positive changes in sleep over time - improved quality and quantity, and using less sleep medication - are linked with improved scores on the General Health Questionnaire (GHQ), which is used by mental health professionals to monitor psychological wellbeing in patients.

People surveyed who reported positive improved sleep scored a two-point change in the GHQ - a result comparable to those recorded from patients completing an eight-week programme of mindfulness-based cognitive therapy designed to improve psychological wellbeing.

The same people showed improvements in physical and emotional health, as well as an ability to perform everyday activities."

Relação entre dormir mais de 9h e Alzheimer?


http://www.techtimes.com/articles/199356/20170226/more-than-nine-hours-of-sleep-could-indicate-alzheimers-disease-here-are-other-warning-signs-of-dementia.htm

Citando:
"Although the researchers did not find a heightened dementia risk for individuals who had been sleeping for nine hours or more a night for more than 13 years, they noticed an increased risk for those who recently started to sleep for more than nine hours.

The researchers found that new long-sleepers have an increased likelihood of developing dementia. Those who recently started to sleep for more than nine hours were found to have a 20 percent increased likelihood of being diagnosed with the neurological condition. They also appeared to have smaller brain volumes."

Mais sobre a higiene do sono

Sobre a higiene do sono, os motivos que podem estar a sabotar o nosso sono e recomendações para cada um deles:

"As well as the new study by Aviva healthcare, an increasing raft of health research suggests it’s time we took our sleep even more seriously, as deprivation can have detrimental effects on everything from our brain power to blood pressure, and has even been linked to early death."

Podemos treinar-nos para dormir menos?

Podemos treinar-nos para dormir menos? A resposta rápida é, por muito que nos custe (aos que gostariam de aproveitar o tempo de sono para fazer outras coisas, o que quer que sejam): Não.

E eis mais uns quantos estudos sobre o sono e o facto e provavelmente não se conseguir reduzir a quantidade de horas de sono (sem afectar a capacidade óptima de processamento do cérebro):

Privação do sononpode levar a depressão?

Que a depressão afecta o sono (insónias) já se sabe. E se o contrário também for verdade?
http://thewire.in/73233/lack-sleep-makes-us-depressed-can/


Citando:
"But could things really be the other way around? Could poor sleep be making you depressed? Over the past decade or so it has become increasingly clear that disturbed sleep often comes before an episode of depression, not afterwards, helping to do away with the notion that sleep problems are secondary to other disorders."
(...)
"It was found that participants who had been sleep deprived for approximately 35 hours showed a greater amygdala response when presented with emotionally negative pictures when compared to those who had not been sleep deprived. Interestingly, links with parts of the brain that regulate the amygdala seemed weaker, too – meaning that the participants were perhaps less able to control their emotions. Such findings could help to explain how poor sleep may actually cause difficulties such as depression."

Recomendações para dormir bem (sequências/fórmulas)

Um pouco senso comum mas é uma sequência/formulação interessante para relembrar:
http://www.telegraph.co.uk/news/newstopics/howaboutthat/12182052/Be-more-productive-This-simple-10-3-2-1-0-formula-could-help.html


Citando:
"The 10-3-2-1-0 formula
10 hours before bed: No more caffeine
3 hours before bed: No more food or alcohol
2 hours before bed: No more work
1 hour before bed: No more screen time
0: The number of times you hit the snooze button in the morning

“The single most important factor in winning your mornings and owning your days is to get up 15 minutes earlier and work on your No. 1 priority before anyone else is awake. It's that simple,” he explains.
“When you follow this formula, you'll get more done and stop letting the big opportunities in your life slip away.”"






E esta sequência/formulação induz alegadamente o sono num minuto (acaba com as insónias):
http://www.telegraph.co.uk/science/2016/03/12/simple-4-7-8-breathing-trick-can-induce-sleep-in-60-seconds/


Citando:
"The trick is holding the breath for four seconds, breathing out then holding for seven seconds. After that exhale completely for a count of eight. The steps are then repeated between two and four times.

Dr Weil says it works because it allows the lungs to become fully charged with air, allowing more oxygen into the body, which promotes a state of calm.


“You have to do this two times a day religiously. It will become a wonderful way to help you fall asleep. You can do it more often throughout the day,” added Dr Weil."
(...)
"The method is based on an ancient Indian practice called pranayama, which means regulation of breath, and is used widely in yoga and pilates."

Informação sobre ciclos do sono em jovens e adolescentes (e horas de exames)

Horas de exames nacionais questionadas:
https://www.publico.pt/sociedade/noticia/o-horario-dos-exames-esta-desajustado-dos-ciclos-do-sono-1736118?frm=ult
Citando:
"O que é indicado é que a marcação de exames deveria, a partir da adolescência, recair no período da tarde, com início às 15h, o que dará a adolescentes e jovens adultos "mais oportunidades de obter uma duração de sono adequada na véspera do exame".
Da mesma forma, e em relação aos horários escolares, Ana Allen Gomes considera que "deixam de estar ajustados" pelo menos a partir do 2.º ciclo do ensino básico: "Não se compreende por que motivo, à medida que a criança se torna mais velha e se aproxima da puberdade, os horários escolares se iniciem mais cedo, o que está em contradição com aquilo que é a tendência oposta com a entrada na puberdade, que é a de atraso [deslocação para mais tarde] do sistema circadiano, como é exemplo o ritmo sono-vigília, com tendência para o adolescente se deitar e levantar mais tarde", diz."
