Bad Karaoke Experiment Explains How Embarrassment Keeps You Up at Night

Shame lives on in the brain.
“Hearing a recording of one’s own voice can be a cringe-worthy experience. Scientists took advantage of that uncomfortable truth, turning up the notch with a karaoke experiment. The goal was to ignite feelings of embarrassment and shame — all in the good name of helpful sleep science.”

People with insomnia have a hard time shedding the distress caused by bad emotional experiences.

That suffering can last weeks — even years — and the researchers wanted to find out exactly why. They had two major questions: What is it about sleep that underlies the problem, and what brain circuits are involved?

So the researchers set out to cause some embarrassment. “To do this, 29 people performed karaoke sessions that were recorded. The catch was that they had to wear headphones that muffled out the sound of their own voice — that way, the scientists could impede pitch correction and promote out-of-tune singing. The participants were not diagnosed with any psychiatric disorders, and they covered a wide range of experiences with insomnia; some had never experienced it, while others were very familiar.”

“Scientists used karaoke to create distressing memories for study participants.
The participants later heard the recordings of their singing while an fMRI machine scanned their brains. They were also exposed to a scent intended to boost their memory of listening to the recordings the next time they smelled it.”

“When asked to choose which emotions they felt after hearing the recording, the most frequent and intense feelings reported were embarrassment and shame. The initial fMRIs confirmed those emotions: As they listened to their out-of-tune singing, the participants’ amygdalae lit up with higher than normal activity. This almond-shaped structure in the brain is involved in processing emotions and is known to activate during emotionally distressing experiences.”

Subsequently, the participants spent the night in the lab hooked up to electroencephalogram monitors. While they slept, the scientists wafted in their trigger smell, curious to see whether it would disrupt their sleep.

“When the participants were brain scanned and exposed to the same song recordings the next morning, a trend emerged: The amygdalae of people who experienced fewer interruptions during rapid eye movement (REM) sleep reacted less strongly than they did the first time around. They felt less embarrassed than they did before. Meanwhile, the people who had fragmented REM sleep ended up feeling more embarrassed than they did on the first go.”

“As for the smells, when compared to the good REM sleepers and control subjects (people in the experiment who were not exposed to a smell), the embarrassment felt by the poor REM sleepers was exacerbated by experiencing the scent.”

“The research team believes that the continuation of embarrassment stems back to the fact that fragmented REM sleep harms the amygdala’s ability to process emotional memories overnight.”

“Processing emotional memories requires synaptic connections to change — some have to be weakened, others strengthened. A chemical called noradrenaline strongly affects the balance between this weakening and strengthening. REM, van Someren explains, is a “very special state” because it is the “only state we have that provides a ‘time-out’ from noradrenaline.”

“People with very restless REM sleep may never enjoy this state anymore. “It is likely that this has repercussions for the balance between weakening and strengthening of synapses, and thus affects overnight emotion regulation.

“In other words, for the majority of people, a night of good REM sleep helps alleviate whatever shame or distress was felt the day before. That doesn’t happen as efficiently when REM sleep is fragmented, and it can become a perpetuating issue. If distress doesn’t dissolve overnight, that can lead to another night of bad sleep, creating a cycle of poor sleep and feeling bad.”

“That state of existence describes the profile of people with insomnia, which van Someren hopes his research can help. He says that instead of focusing on examining sleep-regulating systems in the brain that have been derailed, his team’s study suggests that the better way to help insomniacs is to look for mechanisms in circuits that regulate emotional memory.”

“We also hope that people start to realize that sleep is not always ‘the more the better,’ but that a maladaptive kind of sleep [one with bad REM] can exist,” he explains.

“Restoring REM sleep through novel treatments could be one way of helping to halt this maladaptive sleep. Healthy sleep is central to overall health — and some distressing memories need help being scooted away from the foremost of your thoughts.”

Did you know?: You are more Microbes, Fungi than HUMAN

“There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells. But these tiny compatriots are invisible to the naked eye.  . . . artist Ben Arthur gives a guided tour of the rich universe of the human microbiome.”

Fun to watch and informative!

YOUR body is host to 101 fungal species, with each person harboring between 9 and 23 strains. 

“A growing number of researchers feel that alongside bacteria, the fungi that inhabit our bodies – or, collectively, the “mycobiome” — may also be influential in both our well-being and, at times, disease.”

If your fungi are out of balance it’s not healthy.

“Even when we are alone, we are never alone. We exist in symbiosis — a wonderful term that refers to different organisms living together. Some animals are colonised by microbes while they are still unfertilised eggs; others pick up their first partners at the moment of birth. We then proceed through our lives in their presence. When we eat, so do they. When we travel, they come along. When we die, they consume us. Every one of us is a zoo in our own right — a colony enclosed within a single body. A multi-species collective. An entire world.”

Changes in our resident microbiota and their collective genome — called the microbiome — have been linked with a wide range of diseases, from various forms of arthritis to depression. At this point scientists tend to focus on which bacterial species might hinder or maintain health.

But our biota comprises a menagerie of microbes. And a growing number of researchers feel that alongside bacteria, the fungi that inhabit our bodies may also be influential in both our well-being and, at times, disease.

Fungi Out Of Balance

A Telltale Sign For Unwanted Fungi

  • French researchers distinguished the fungi present in healthy human lungs compared with those afflicted with cystic fibrosis. Aspergillus was most prevalent in the lungs of healthy people, whereas various Candida species dominated in those afflicted with CF and other lung disorders.
  • UCLA professor David Underhill  found that mammalian fungi interact with the immune system to control inflammation in the gut.
  • Mice in which the gene encoding for Dectin-1 was inactivated and in which colitis was induced came down with far more severe disease than mice with the active gene. With these findings in hand they then identified a Dectin-1 gene variant in humans that predicted a severe form of inflammatory bowel disease called ulcerative colitis.
  • Recent unpublished findings by Ghannom’s lab show that an interaction between fungi and bacteria in the gut aggravates the body’s autoimmune response in Crohn’s disease, another form of inflammatory bowel disease.
  • In collaboration with a group at Cleveland Clinic, Ghannoum also beginning to show that oral fungal populations are different in people with head and neck cancers.
  • Recent research found that autoimmune arthritis can be induced in mice injected with certain compounds found in fungal cell walls.

“None of these factors are working in isolation . . .it’s probably a confluence of them all interacting with each other and with us – what we eat, what kind of nutrients they have, genetic influences and how our immune system reacts to both fungi and bacteria in the gut.”

“We’re in a stage where we’re recognizing the biological significance of the fungi in our systems to help develop a common language and set of research approaches,” Underhill says. “Soon, hopefully, we’ll know how they can be good for us, bad for us and manipulated to our benefit.”

“There’s a certain beauty in our biologic cooperative; a reminder that mammalian life is complicated and communal, and that in nature imbalance has consequences. But perhaps tinkering with our fungal dwellers will one day help restore our biologic balance and fend off disease.”

“Stress-related disorders and diseases have been on the rise in the whole population for decades, according to data from the Centers for Disease Control and Prevention, including those leading to . . . deaths of despair, but also to heart disease, obesity, and diabetes.”

“National surveys by the American Psychological Association that also capture how stressed, anxious and overwhelmed we feel show a similar increasing pattern. And it shows up in our bodies, even before we get sick or start down the many roads to self-harm.”

I personally have experienced just that.  My fibromyalgia flared for the first time during a particularly stressful time in my life.  The truth is I didn’t realize how stressed I was at the time.  Years later, it dawned on me that I had been in the center of  “the perfect” storm of stressful circumstances: My aging parents and in-laws were dying; my work focused on anger, anxiety, depression – any and all forms of psychological tension or stress; and my own hormonal changes.

I’ve seen similar circumstances with many clients and colleagues who, like me, coped with and habituated to the level of stress they were under and often didn’t know the magnitude of impact until much later when they became ill.  

All of us experience stress from work, money worries, traffic, political news, deadline pressure, relationship difficulties etc. and an even more basic cause which lies hidden at the intersection of psychology and biology:

Biology

“A central biological pathway is from excess cortisol — the fight-or-flight hormone — that characterizes being over-stressed for long periods of time. This “stress dysregulation” leads to risky health decisions, like addiction or overeating, and directly to many health problems linked to excess cortisol.”

Psychology

  • How we THINK triggers the stress response.  We don’t have to actually be in a stressful situation – it’s our perception of it that alone can trigger a neuro-biological stress response.
  • Slow-moving and cumulative social forces “get under the skin” early in life and can show up decades later in morbidity and mortality.
  • Losing a sense of control that you believed you had, whether real or not, justified or not, creates stressful dislocations.

There are many things that can be done to “de-stress”.  Most require time, money, effort or all three.  Basically, we like what is quick and easy.  To that end we’ve accumulated information and exercises over the 30 decades each of us was in practice and have now compiled some of it into a 19 page FREE PDF.
