The influence of sleep deprivation and oscillating motion on sleepiness, motion sickness, and cognitive and motor performance - Kaplan J, Ventura J, Bakshi A, Pieobon A, Lackner JR, DiZio P.
Our goal was to determine how sleep deprivation, nauseogenic motion, and a combination of motion and sleep deprivation affect cognitive vigilance, visual-spatial perception, motor learning and retention, and balance. We exposed four groups of subjects to d... (Source: SafetyLit)

Reading Makes You Carsick Because Your Brain Thinks It's Being Poisoned
(Photo: Toni Barth/EyeEm)
By Melissa Dahl
There are those who can happily while away a long road trip with the companionship of a good book, their minds flying away with the plot even as their bodies remain motionless in the passenger seat of a car plowing along a freeway. And then there are those -- well, there are those for whom this all sounds very nice in theory but who know that in reality it would probably result in nausea at best, actual vomit at worst. Carsickness is an annoying quirk of human physiology, but it's one that has more to do with your "idiot brain" than you'd probably think, as neuroscientist and aut...

A Neuroscientist Explores The Illogical Behaviors Of The Mind In 'Idiot Brain'
Dean Burnett says the human brain is like a computer that files information in a way that defies logic. According to Burnett, brains can alter memory, cause motion sickness and affect intelligence. (Source: NPR Health and Science)

Don ’ t Stop Thinking About Tomorrow: How Participatory Medicine Helped My Family
On Halloween night 2014, my mother and I found ourselves sitting in an executive suite at the Verizon Center in Washington, DC, eagerly awaiting to see my favorite band, Fleetwood Mac. I know it may be a little odd that someone my age, which at the time was 21, is obsessed with that band and not something more “hip” like one of the flavor of the week popstars, but what can I say? I have good taste in music, thanks in part to my mother.
As the lights in the arena went down and Stevie Nicks and the group took the stage, I couldn’t help but think how lucky I was to be here with my mother. Looking back now, it is quite ...

Sopite syndrome in wind-excited buildings: productivity and wellbeing impacts - Lamb S, Kwok KCS.
Tall buildings vibrate in response to strong winds at frequencies below 1 Hz, which can cause motion sickness and sopite syndrome in humans. Sopite syndrome is characterized by sleepiness, low motivation and low mood that can reduce productivity in office ... (Source: SafetyLit)

Tips to Prevent Kids from Getting Car Sick
Packing up the kids for a road trip can be difficult. Making sure they are stocked with things to do to keep them occupied can be a tough battle on its own. If car sickness, a common type of motion sickness, is thrown into the equation, road trips can be even more of a struggle. [...] (Source: News from Mayo Clinic)

What Causes Vomiting?
Discussion
Regurgitation is a passive expulsion of ingested material out of the mouth. It is a normal part of digestion for ruminants such as cows and camels. Nausea is an unpleasant abdominal perception that the person may describe as feeling ill to the stomach, or feeling like he/she is going to vomit. Anorexia is frequently observed. Nausea is usually associated with decreased stomach activity and motility in the small intestine. Parasympathetic activity may be increased causing pale skin, sweating, hypersalivation and possible vasovagal syndrome (hypotension and bradycardia). Retching or dry heaves is when there are sp...

Scott Kelly Happy to Be Back on Earth: ‘This Feels Great’
It would take a brave astronaut to eat the dates, raisins and sweetened dough they serve up during the welcome home ceremony at Zheskagzan airport in Kazakhstan. Dates, raisins and sweetened dough would surely look good to a space station crew member who has just put in the average six-month hitch in orbit—to say nothing of Scott Kelly and Mikhail Kornienko after nearly a full year.
But what an astronaut’s stomach says and what an astronaut’s otoliths say are two different things, and when you’re back on Earth and feeling the tug of gravity after a long period in weightlessness, it’s the otoli...

No, the Apollo 10 Astronauts Didn’t Hear ‘Alien Music’ Behind the Moon
There are two ways to try to get attention on the science blogs and in the space nerd circuit: One, claim that there’s a deep, unexplained secret NASA is keeping about an alien encounter during the Apollo era. Or two, don’t claim that there’s a deep, unexplained secret NASA is keeping about an alien encounter during the Apollo era. Which do you think gets you more attention?
If you didn’t have to puzzle too hard over that one, you probably aren’t surprised at all by the attention being paid to a late-breaking, “newly declassified” story that the Apollo 10 astronauts heard alien mus...

Virtual reality makes its best users the most queasy
In a twist of virtual fate, people with the best 3-D vision are also the people most likely to suffer from motion sickness while using virtual reality displays. Researchers demonstrated this irony by playing motion-heavy videos for study participants through the Oculus Rift. Nearly two-thirds of the study subjects quit watching the videos early, overcome by nausea. (Source: ScienceDaily Headlines)

Biodynamic hypothesis for the frequency tuning of motion sickness - Golding JF, Gresty MA.
INTRODUCTION: Motion sickness is often provoked by oscillatory translational (linear) acceleration. For humans, motion frequencies around 0.2-0.3 Hz are the most provocative. A current explanation for this frequency band is that it spans a region of maximu... (Source: SafetyLit)
