The connections between lack of sleep and cancer

Did you know, for example, that long stretches of shift work may increase cancer risk.

Johns Hopkins Medicine »

Long-term sleep disruptions may raise the risk of some cancers. But sleep and cancer are intertwined in other ways too. Getting a good night’s sleep is difficult during cancer treatment and can be a lifelong challenge for survivors.

“In our research, nearly one in four survivors of childhood cancer had difficulty falling asleep and staying asleep,” says cancer expert Kathryn Ruble, M.S.N., Ph.D. , of the Johns Hopkins Kimmel Cancer Center . “Helping cancer survivors improve their sleep might help them perform at school, on the job, and throughout their lives.”

Disruptions in the body’s “biological clock,” which controls sleep and thousands of other functions, may raise the odds of cancers of the breast, colon, ovaries and prostate. Exposure to light while working overnight shifts for several years may reduce levels of melatonin, encouraging cancer to grow.

Sleep is your life-support system and Mother Nature’s best effort yet at immortality, says sleep scientist Matt Walker. In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep — and the alarmingly bad things that happen when you don’t, for both your brain and body. Learn more about sleep’s impact on your learning, memory, immune system and even your genetic code — as well as some helpful tips for getting some shut-eye.

A good night’s sleep can help reduce anxiety

 

Yasmin Anwar »

Researchers have found that the type of sleep most apt to calm and reset the anxious brain is deep sleep, also known as non-rapid eye movement (NREM) slow-wave sleep, a state in which neural oscillations become highly synchronized, and heart rates and blood pressure drop.

“We have identified a new function of deep sleep, one that decreases anxiety overnight by reorganizing connections in the brain,” said study senior author Matthew Walker, a UC Berkeley professor of neuroscience and psychology. “Deep sleep seems to be a natural anxiolytic (anxiety inhibitor), so long as we get it each and every night.”

The findings, published this month in the journal Nature Human Behaviour, provide one of the strongest neural links between sleep and anxiety to date. They also point to sleep as a natural, non-pharmaceutical remedy for anxiety disorders, which have been diagnosed in some 40 million American adults and are rising among children and teens.

A 4-day workweek at Microsoft Japan boosted employees’ productivity

Microsoft experimented with a four-day workweek this past August. Employees received Fridays as paid leave. Not 92% of employees were happy with the program.

Humza Aamir, writing in Techspot » 

All of 2,300 employees working at Microsoft Japan had three-day weekends in August this year, as part of the company’s ‘Work Life Choice Challenge.’

[…]

Getting an extra day off every week made for improvements in several areas, including productivity and operational costs. Sales per employee, used to determine productivity, rose by 39.9 percent as compared to figures in August 2018, while remaining closed for an extra day reduced the firm’s electricity costs by 23.1 percent and saw a 58.7 percent decline in paper printing.

Given that employees had only four days to work, meetings were capped at 30 minutes, while remote conferences were increased to eliminate commuting where possible. The experiment also incorporated self-development and family wellness schemes and received positive feedback by the majority of employees, 92.1 percent of whom liked the shorter workweek.

Too many bad nights of sleep could play a role in developing dementia

Katherine Ellen Foley, writing in Quartz »

“Sleep disorders and insufficient sleep contribute to Alzheimer’s decades before people develop the disorder,” Ruth Benca, a psychiatrist at the University of California, Irvine, said during a panel on brain health at the summit in Washington, DC.

Benca’s work has tracked the relationship between sleep—particularly the deep sleep known as rapid-eye movement (REM)—and its relationship to developing dementia later in life. In 2017, she and her team published work following healthy individuals with a variant of a gene called APOE that puts them at a higher risk of developing Alzheimer’s. They found that individuals who reported lower-quality sleep tended to have larger buildups of the proteins associated with Alzheimer’s disease, called amyloid and tau, in the fluid surrounding their brains than those who reported sleeping well. It seemed, they thought, that the process of sleep might be clearing some of these buildups.

Subsequent work has backed up that theory. The same year, another study found that among a cohort of adults over 60, those who took longer to enter REM sleep and dreamt less were at an elevated risk of developing dementia. Last year, researchers from the National Institutes of Health in Bethesda, Maryland published the results of a study that found healthy participants who agreed to be woken up hourly for a night (yeesh) had higher levels of amyloid the following day. And earlier this year, a separate group from Washington University School of Medicine found that older adults who got less REM sleep were likely to have higher amounts of tau, too.

About 30% of Canadians suffer from a sleep disorder

Maryse Zeidler at the CBC News writes »

Dr. Ram Randhawa, a psychiatrist at the University of British Columbia’s Sleep Disorders Program, says about 30 per cent of Canadians struggle with getting to or staying sleep at any given time. The prevalence of insomnia does seem to be higher among women, he said.

For most people, sleep issues are a temporary problem brought on by stress or worry. For some, they can be a debilitating, life-long problem.

The Stress of Separation and Detention Changes the Lives of Children

These actions have focused outrage and attention on the current U.S. Administration’s callous, racial, and white supremacist agenda.

What shocks me the most is not that these actions are supported by many Americans. The U.S.A. has a long history of problems over race. What shocks me the most is just how deep and wide the support really is.

This is the United States of America today. This is what is happening now. And there is a good chance this will continue for a while as there’s a good chance he will get reelected.

The horrific conditions under which immigrants and especially immigrant children are being held in US detention centers, rightly reminds us of the Nazi concentration camps. Lessons of the past have been forgotten.

What I’ve Learned: If their words don’t match their actions, trust their actions. More important than talk is how one lives their life and how they treat others.

Isaac Chotiner, writing for The New Yorker (paywall):

What most concerns you about what we have read about and seen from these border facilities holding children?

Oh, God, where do I begin? I think—to cut through all of the noise, the politics, the back-and-forth on the details—there are just two core issues that are screaming out. One is the fact that the forced and abrupt separation of children from their parents is a huge psychological trauma and assault. The magnitude of the nature of the crisis for a child’s health and well-being cannot be overstated. Abrupt separation from primary caregivers or parents is a major psychological emergency.

The second issue is the prolonged placement of children in institutional settings. Obviously, the two are linked in this particular situation. From the perspective of what we know about children’s health and well-being, what we know about trauma, abrupt separation is one area where we have a lot of research and a lot of evidence about its consequences. But prolonged institutionalization is a separate area in which we have an equally deep research base and knowledge about how damaging that kind of setting is for kids. We are dealing with two very well-studied, serious assaults on the health and well-being of children.

If you are not getting enough sleep, it’s killing you. Literally

According to neuroscientist Matthew Walker, not sleeping enough makes you:

… makes you dumber, more forgetful, unable to learn new things, more vulnerable to dementia, more likely to die of a heart attack, less able to fend off sickness with a strong immune system, more likely to get cancer, and it makes our bodies literally hurt more. Lack of sleep distorts your genes, and increases your risk of death generally, he said. It disrupts the creation of sex hormones like estrogen and testosterone, and leads to premature aging. Apparently, men who only sleep five hours a night have markedly smaller testicles than men who sleep more than seven.

“Sleep loss will leak down into every nook and cranny of your physiology,” he said. “Sleep, unfortunately, is not an optional lifestyle luxury. Sleep is a nonnegotiable biological necessity. It is your life support system.”
