Does the full moon make us sleepless? A neurologist explains the science behind sleep, mood and lunar myths
Research indicates that the moon slightly affects sleep, particularly in the days leading up to a full moon, causing people to lose about 15 to 30 minutes of sleep. However, the direct connection between lunar phases and mental health issues remains largely unsupported by scientific data, with artificial light impacts being more significant.

Have you ever tossed and turned under a full moon and wondered if its glow was keeping you awake? For generations, people have believed that the Moon has the power to stir up sleepless nights and strange behavior – even madness itself. The word “lunacy” comes directly from luna, Latin for Moon.
Police officers, hospital staff and emergency workers often swear that their nights get busier under a full moon. But does science back that up?
The answer is, of course, more nuanced than folklore suggests. Research shows a full moon can modestly affect sleep, but its influence on mental health is much less certain.
I’m a neurologist specializing in sleep medicine who studies how sleep affects brain health. I find it captivating that an ancient myth about moonlight and madness might trace back to something far more ordinary: our restless, moonlit sleep.
What the full moon really does to sleep
Several studies show that people really do sleep differently in the days leading up to the full moon, when moonlight shines brightest in the evening sky. During this period, people sleep about 20 minutes less, take longer to fall asleep and spend less time in deep, restorative sleep. Large population studies confirm the pattern, finding that people across different cultures tend to go to bed later and sleep for shorter periods in the nights before a full moon.
The most likely reason is light. A bright moon in the evening can delay the body’s internal clock, reduce melatonin – the hormone that signals bedtime – and keep the brain more alert.
The changes are modest. Most people lose only 15 to 30 minutes of sleep, but the effect is measurable. It is strongest in places without artificial light, such as rural areas or while camping. Some research also suggests that men and women may be affected differently. For instance, men seem to lose more sleep during the waxing phase, while women experience slightly less deep and restful sleep around the full moon.
The link with mental health
For centuries, people have blamed the full moon for stirring up madness. Folklore suggested that its glow could spark mania in bipolar disorder, provoke seizures in people with epilepsy or trigger psychosis in those with schizophrenia. The theory was simple: lose sleep under a bright moon and vulnerable minds might unravel.
Modern science adds an important twist. Research is clear that sleep loss itself is a powerful driver of mental health problems. Even one rough night can heighten anxiety and drag down mood. Ongoing sleep disruption raises the risk of depression, suicidal thoughts and flare-ups of conditions like bipolar disorder and schizophrenia.
That means even the modest sleep loss seen around a full moon could matter more for people who are already at risk. Someone with bipolar disorder, for example, may be far more sensitive to shortened or fragmented sleep than the average person.
But here’s the catch: When researchers step back and look at large groups of people, the evidence that lunar phases trigger psychiatric crises is weak. No reliable pattern has been found between the Moon and hospital admissions, discharges or lengths of stay.
But a few other studies suggest there may be small effects. In India, psychiatric hospitals recorded more use of restraints during full moons, based on data collected between 2016 and 2017. In China, researchers noted a slight rise in schizophrenia admissions around the full moon, using hospital records from 2012 to 2017. Still, these findings are not consistent worldwide and may reflect cultural factors or local hospital practices as much as biology.
In the end, the Moon may shave a little time off our sleep, and sleep loss can certainly influence mental health, especially for people who are more vulnerable. That includes those with conditions like depression, bipolar disorder, schizophrenia or epilepsy, and teenagers who are especially sensitive to sleep disruption. But the idea that the full moon directly drives waves of psychiatric illness remains more myth than reality. https://www.youtube.com/embed/Q17i1srjOqY?wmode=transparent&start=0 The sleep/wake cycle is synchronized with lunar phases.
Other theories fall short
Over the years, scientists have explored other explanations for supposed lunar effects, from gravitational “tidal” pulls on the body to subtle geomagnetic changes and shifts in barometric pressure. Yet, none of these mechanisms hold up under scrutiny.
The gravitational forces that move oceans are far too weak to affect human physiology, and studies of geomagnetic and atmospheric changes during lunar phases have yielded inconsistent or negligible results. This makes sleep disruption from nighttime light exposure the most plausible link between the Moon and human behavior.
Why the myth lingers
If the science is so inconclusive, why do so many people believe in the “full moon effect”? Psychologists point to a concept called illusory correlation. We notice and remember the unusual nights that coincide with a full moon but forget the many nights when nothing happened.
The Moon is also highly visible. Unlike hidden sleep disruptors such as stress, caffeine or scrolling on a phone, the Moon is right there in the sky, easy to blame.
Lessons from the Moon for modern sleep
Even if the Moon does not drive us “mad,” its small influence on sleep highlights something important: Light at night matters.
Our bodies are designed to follow the natural cycle of light and dark. Extra light in the evening, whether from moonlight, streetlights or phone screens, can delay circadian rhythms, reduce melatonin and lead to lighter, more fragmented sleep.
This same biology helps explain the health risks of daylight saving time. When clocks “spring forward,” evenings stay artificially brighter. That shift delays sleep and disrupts circadian timing on a much larger scale than the Moon, contributing to increased accidents and cardiovascular risks, as well as reduced workplace safety.
In our modern world, artificial light has a much bigger impact on sleep than the Moon ever will. That is why many sleep experts argue for permanent standard time, which better matches our biological rhythms.
So if you find yourself restless on a full moon night, you may not be imagining things – the Moon can tug at your sleep. But if sleeplessness happens often, look closer to home. It is likely a culprit of the light in your hand rather than the one in the sky.

Rod's Pure Thoughts
Remembering Patrick Stewart: A Star Trek Journey Through My Life
Remembering Patrick Stewart: From childhood adventures with Kirk to finding another favorite captain in Picard, Rod Washington reflects on Patrick Stewart, the Next Generation cast, and the creativity they inspired.
From childhood afternoons with the original Enterprise crew to the reunion in Picard, Star Trek has been part of my life for decades. Patrick Stewart helped make that journey unforgettable.
Remembering Patrick Stewart
The news of Sir Patrick Stewart’s passing has me thinking about how much of my life has had Star Trek somewhere in the background—and often right in the foreground.
Star Trek: The Original Series has been my favorite since I was in single digits. Kirk, Spock, McCoy and the rest of that crew were part of my childhood. Long before there was a Captain Picard, that was my Enterprise.
Then came the motion-picture era with the original cast. The Wrath of Khan arrived during my teenage years. The Voyage Home followed in my young adulthood. As I grew up, those familiar characters kept coming back with new adventures.
Then we got a new Enterprise and a new generation.
A New Crew Earned Its Place
When Star Trek: The Next Generation began, my reaction was something like, “It’s okay.”
I continued watching. I was curious, but I already had a strong attachment to the original crew. That kind of connection takes time to build.
By the end of the first season, though, I was crazy about The Next Generation.
Patrick Stewart had a lot to do with that. His portrayal of Jean-Luc Picard gave me another captain to believe in. He had his own presence, his own way of handling a situation, and a way of making you listen when he spoke.
Eventually, Picard was on par with Kirk in my eyes. Coming from someone who had loved the original series since childhood, that says a lot.
From the Enterprise to First Contact
The series became an important part of my adult entertainment life. I cared about the characters and wanted to see where their stories would go.
After the television series ended, the TNG movies gave us more time with them. My favorite remains First Contact. It is the one that stands out most for me from that chapter of Star Trek.
Looking back, I can trace different stages of my life through these shows and movies: childhood with the original series, my teenage years with The Wrath of Khan, young adulthood with The Voyage Home, and then the years spent getting to know Picard’s crew.
That is a long relationship to have with a fictional universe. The people who bring it to life become familiar faces across decades.
Seeing Everyone Together Again
By the time Star Trek: Picard arrived, I was well into another chapter of my own life.
It was fun to see those familiar faces again, especially when the crew came back together. There was a lot of personal history attached to watching them share the screen.
Patrick Stewart and the rest of the cast—and yes, that includes Wil Wheaton—were an important part of my adult life as a viewer. Each contributed to a crew I grew to love.
Seeing them again brought back the feeling that had kept me watching all those years earlier.
Thank You for the Inspiration
What stays with me most is how much creativity those performances sparked.
As someone who enjoys filmmaking and storytelling, I appreciate entertainment that leaves me wanting to create something of my own. Stewart and his castmates gave me that feeling many times over the years.
His passing makes me appreciate the time we had with him on screen and the work we can return to. I can watch an episode, revisit First Contact, or spend another evening with the crew and remember why these stories meant so much to me.
The original series will always have that special place in my heart. Patrick Stewart helped another Enterprise crew earn a place there, too.
Thank you, Sir Patrick, for the years of entertainment, the inspiration, and a captain who became part of my life.
News Background
Stewart died October 28, 2026, at age 86, according to his spokesperson’s statement reported by Reuters. This entry is a personal reflection on his work and its place in my life.

Golden Bird in Compton: When Mom Took a Night Off
Golden Bird in Compton was an occasional Friday or Saturday treat when Mom wanted a break from cooking. A personal look back at its Alondra Boulevard location and the memories that linger.
Some childhood meals stay with you for decades. For me, Golden Bird fried chicken in Compton is one of them.
Growing up in the Los Angeles area, an occasional Friday or Saturday meant my mom wanted a break from cooking. Those were the nights when takeout became a treat, and Golden Bird was one of the places I remember enjoying most.
The location on East Alondra Boulevard sounds like the one we visited. Researching it brought me to 2600 East Alondra Boulevard, Compton—an address listed in Los Angeles County records under Golden Bird #1.
An address can help place a memory on a map. But what I remember most is much simpler: the chicken was delicious, and getting it was a welcome weekend treat.
Part of Our Family’s Takeout Rotation
Golden Bird wasn’t our only chicken stop. Over the years, there was Pioneer, KFC, Church’s, Louisiana Fried Chicken, and later Popeyes. I also remember Jim Dandy from when I was very young, especially its crinkle-cut fries.
Each name brings back a different memory. Golden Bird brings me back to Compton and those evenings when my mother could take some time off from preparing dinner.
As a kid, I thought about enjoying the food. Looking back, I also appreciate what those meals meant for her: one less dinner to cook and a chance to take a break.
The History Behind the Address
Golden Bird’s own history describes a family recipe associated with Zelma and a wet batter designed to give the chicken a crisp outside while keeping the meat moist. My own memory is simply that I loved eating it.
The Alondra Boulevard location also connects to another chapter in Southern California’s fried-chicken history. Vincent Williams opened a Compton Golden Bird franchise in 1983, according to the Los Angeles Times.
A later profile described Williams developing his Honey’s Kettle concept in his former Compton franchise location. Honey’s Kettle dates its beginnings on Alondra Boulevard to 2000, and a 2012 restaurant visit documented its original location at 2600 East Alondra Boulevard. Those accounts point to a connection between the two businesses at that address.
I haven’t established who operated the restaurant during every year my family visited. But learning about its history adds another layer to a place I remember through its food.
A Weekend Memory Worth Keeping
For me, Golden Bird’s place in the story starts with family. It was an occasional treat, a meal I enjoyed, and a Friday or Saturday when Mom could let someone else handle the cooking.
Decades later, that is still a good reason to remember a neighborhood restaurant.
Editor’s note: Golden Bird is still serving fried chicken in South Los Angeles at 8300 South Western Avenue, at West 83rd Street. For those of us who remember it as a weekend family treat, it’s good to know the Golden Bird name remains part of LA’s food scene. Order pickup and delivery

For generations, the Santa Monica Pier sign has marked the start of a day at the beach. Now, the familiar blue neon landmark is preparing for a journey of its own.
Santa Monica scheduled removal of the 1941 sign for October 20–22, with shipment to Las Vegas anticipated October 26. The timetable is subject to change, according to the city’s October 19 announcement.
The temporary removal accompanies replacement of the aging bridge connecting Ocean Avenue to the pier. It also creates an opportunity to preserve the historic sign.
YESCO will restore it at its Las Vegas facility. The company’s experience includes work on the “Welcome to Fabulous Las Vegas” sign.
Crews will repair neon tubing, treat rust, repaint components and address structural needs while retaining historic features. The sign will remain in secure storage during bridge construction.
Once the project is finished, it will return above the new bridge at a slightly greater height for visibility and vehicle clearance. The city’s latest announcement targets project completion by 2028, ahead of the Los Angeles Olympics and Paralympics.
Meanwhile, visitors can photograph a lighted, half-scale replica near Pier Burger.
For anyone who associates that glowing arch with Southern California memories, its absence will be noticeable. The restoration is intended to ensure future generations can make memories beneath it, too.
