TITLE: Morning sunlight exposure is linked to earlier sleep schedules

URL: https://www.psypost.org/morning-sunlight-exposure-is-linked-to-earlier-sleep-schedules/

Exposure to natural sunlight early in the day is associated with earlier sleep schedules and better overall rest. Researchers found that adults who spent more time in the morning sun had a more aligned internal biological clock, which can promote healthier sleep patterns. The study was published in the journal BMC Public Health.

The human body relies on an internal biological clock, known as the circadian rhythm, to manage sleep and wake cycles. This rhythm is governed by a tiny region in the brain called the suprachiasmatic nucleus. When light enters the eyes, signals travel to this brain region, which then guides the release of various chemical messengers.

One major messenger is melatonin, a hormone that promotes sleepiness. When darkness falls, the body produces more melatonin. When the eyes detect bright light, melatonin production drops, promoting wakefulness.

Modern lifestyles limit how much natural light people receive. Many adults work indoors or spend their leisure time looking at screens. During the COVID-19 pandemic, lockdowns and remote work dramatically reduced the amount of time people spent outside.

Extended periods spent indoors can disrupt the biological clock. When a person’s biological time falls out of sync with their daily obligations, such as waking up early for work despite not feeling rested, they can experience chronic exhaustion. This misalignment is sometimes called social jetlag.

Lead researcher Luiz Antônio Alves de Menezes-Júnior, a public health and nutrition researcher at the Federal University of Ouro Preto in Brazil, and his colleagues wanted to understand how sunlight at different times of the day affects specific elements of sleep. The researchers focused heavily on a metric called the midpoint of sleep, which is the exact halfway mark between the time a person falls asleep and the time they wake up. An earlier midpoint indicates a sleep cycle that is well-synchronized with the natural progression of day and night. A delayed midpoint can mean the internal clock is out of sync with typical social and work schedules.

The researchers conducted a cross-sectional survey of 1,762 adults living in the Iron Quadrilateral region of Brazil between October and December 2020. Interviewers visited homes in two mid-sized cities, using protective measures to prevent the spread of the coronavirus. They randomly selected households from census data, aiming to capture a representative sample across various socioeconomic groups. The participants answered detailed questions about their general health, socioeconomic status, and daily habits.

To evaluate sleep, the participants completed the Pittsburgh Sleep Quality Index, which is a validated questionnaire used to measure different dimensions of rest over the previous month. This tool helped the researchers calculate each person’s total sleep time, the amount of time it took them to fall asleep, and their sleep efficiency. Sleep efficiency is the percentage of time a person spends actually sleeping while in bed. The questionnaire also provided the data needed to calculate each participant’s midpoint of sleep and their overall sleep quality score.

Overall, the participants reported an average total sleep time of just over seven hours per night. The average sleep midpoint was around 5:18 a.m., meaning the typical participant fell asleep shortly before midnight and woke up just after 7:00 a.m.

To track light exposure, the researchers asked the participants to estimate how many days a week they spent time in the sun. The participants then estimated how many minutes they spent in the sun on those days across three specific time windows. These windows were before 10 a.m., between 10 a.m. and 3 p.m., and after 3 p.m.

The research team used statistical models to look for relationships between the timing of sunlight exposure and the various sleep metrics. To analyze the results, they used a directed acyclic graph, which is a theoretical model that maps out how different variables might influence one another. This helped them select the correct factors to adjust for in their models, avoiding false associations. They factored in variables such as age, gender, education level, chronic health conditions, and levels of physical activity.

The researchers found that morning sunlight exposure had the strongest relationship with the midpoint of sleep. For every additional 30 minutes a participant spent in the sun before 10 a.m., their sleep midpoint shifted earlier by an average of 23 minutes. The findings suggest that morning light serves as a primary signal to help reset the biological clock.

Afternoon sunlight exposure also showed a relationship with the sleep midpoint, though the effect was smaller. Every 30 minutes of sun exposure after 3 p.m. was associated with a 19-minute earlier sleep midpoint. The researchers noted that afternoon sunlight might signal the approaching evening, or it might coincide with outdoor physical activity that generally aids sleep.

Sunlight exposure in the middle of the day, between 10 a.m. and 3 p.m., had no statistically significant association with the midpoint of sleep. The lack of an association between midday light and sleep timing suggests that the biological clock is most responsive to light at the extremes of the day.

Beyond the sleep midpoint, morning sunlight was the only time window associated with a better overall sleep quality score on the questionnaire. People who spent more time outside before 10 a.m. reported generally better rest.

Conversely, sunlight exposure at any time of day showed no statistically significant association with total sleep time. Light exposure also had no statistically significant association with how quickly participants fell asleep or their sleep efficiency.

The study relies on observational data, meaning it can only identify patterns rather than prove that sunlight exposure directly causes sleep changes. The participants estimated their own sun exposure and sleep habits, which can introduce memory errors or biases compared to using objective tracking devices.

The researchers calculated a single average sleep midpoint for each participant for the entire week. They did not separate sleep data for workdays versus weekends. People often sleep in on their days off to catch up on rest. A broader weekly average might mask the specific effects of varying daily schedules and weekend sleep habits.

The analysis did not track exposure to artificial light or the amount of time participants spent looking at screens in the evening. Late-day screen light is known to influence sleep onset and biological rhythms, which could skew the interpreted effects of natural sunlight. Additionally, the sleep efficiency data was based entirely on self-reports. Measuring true sleep efficiency generally requires clinical tools like movement-tracking wristbands or formal sleep studies in a laboratory setting.

The data collection took place during the first year of the COVID-19 pandemic, a period marked by high social isolation, anxiety, and altered work routines. These unique societal conditions likely influenced the participants’ stress levels and sleep patterns in ways that are difficult to separate from their light exposure. Future research could use wearable technology to measure outdoor light exposure and sleep patterns precisely, helping clarify exactly how natural light guides the human biological clock under normal daily conditions.

The study, “The role of sunlight in sleep regulation: analysis of morning, evening and late exposure,” was authored by Luiz Antônio Alves de Menezes-Júnior, Thais da Silva Sabião, Júlia Cristina Cardoso Carraro, George Luiz Lins Machado-Coelho, and Adriana Lúcia Meireles.

TITLE: Stopping ADHD medication alters sleep rhythms long after discontinuation

URL: https://www.psypost.org/stopping-adhd-medication-alters-sleep-rhythms-long-after-discontinuation/

Stopping the common attention-deficit/hyperactivity disorder medication methylphenidate can cause lasting disruptions to sleep and activity rhythms. In a recent animal study, researchers found that both adolescent and adult rats experienced reduced rest quality ten days after they stopped taking the drug. The research was published in the journal Psychopharmacology.

Children and adults with attention-deficit/hyperactivity disorder, or ADHD, often experience higher rates of sleep disturbances than their peers. These issues range from difficulty falling asleep to experiencing fragmented and shortened periods of rest. Because sleep problems are so common in this population, medical professionals increasingly view ADHD as a condition that affects people throughout the entire day and night.

The most frequently prescribed treatment for pediatric ADHD is methylphenidate. This psychostimulant helps improve attention and reduce hyperactivity. Patients taking the drug occasionally report side effects like delayed sleep onset and insomnia.

Treatment discontinuation among people with ADHD is highly prevalent. Medical data suggests that a large portion of patients eventually stop taking their prescribed psychostimulants, with the highest dropout rates occurring among young adults.

Researchers have debated whether the medication itself worsens existing sleep disturbances or contributes to new sleep disorders later in life. Much of the existing data focuses on the drug’s effects while a patient is actively taking it. Very few clinical or laboratory studies have tracked what happens to sleep patterns once the medication is stopped.

To answer this question, researchers led by psychologist Leslie R. Amodeo and graduate researcher Carolyn Cueto at California State University, San Bernardino, designed an experiment using an animal model. By observing rats without an underlying disorder, the team aimed to isolate the physiological effects of the drug from the behavioral symptoms of ADHD. They investigated how methylphenidate influenced the natural rest and wake cycles of male and female rats during both adolescence and adulthood.

The experiment involved one hundred and eight Long-Evans rats divided into groups of 56 adolescents and 52 adults. The animals received either a saline control injection or a specific dose of methylphenidate twice a day for ten days. The researchers administered doses of one or two milligrams per kilogram, which correspond to clinically relevant levels in human patients. To mimic the prolonged exposure typical of medical treatment, the researchers administered the drug in the morning and the evening.

To measure activity levels, the researchers fitted each rat with a customized spandex jacket equipped with a lightweight commercial activity monitor. These monitors tracked the animals’ physical movements continuously throughout a twenty-four-hour cycle. Rats are nocturnal animals, meaning they are naturally active in the dark and rest when their environment is brightly lit.

The research team gathered minute-by-minute movement data on three specific days. They analyzed activity on the final day of the medication regimen, on the first day after the drug was stopped, and ten days after the treatment ended.

On the final day of treatment, the medication increased overall activity levels across both the light and dark phases. Adult rats receiving the higher dose experienced longer and more frequent active periods during their usual waking hours in the dark. The researchers also noticed shifts in the timing of the animals’ daily circadian rhythms, with peak activity occurring later than usual.

The medication altered the quality of rest during the light phase as well. Female rats in particular showed signs of impaired rest on the last day of the drug regimen. They experienced fewer total rest periods and exhibited more fragmented sleep patterns compared to those receiving the saline control.

The researchers then stopped the injections and observed the animals during the first twenty-four hours of withdrawal. During this acute discontinuation phase, the rats’ activity patterns began to shift in the opposite direction. The previously sustained periods of wakefulness seen in adult rats shortened and became more erratic.

During their normal resting phase in the light, the rats undergoing acute withdrawal continued to experience sleep disruptions. Adolescent rats that had received the lower dose of the drug showed shorter rest episodes than their peers in the control group. Both male and female rats experienced an increase in rest fragmentation, meaning their periods of stillness were frequently interrupted by bursts of movement.

The most pronounced impairments emerged ten days after the animals stopped taking the medication. During this prolonged withdrawal phase, widespread disruptions to rest quality appeared across all age and sex groups. Rats that had been given methylphenidate experienced a drop in both the total number of rest episodes and the average duration of each resting period.

The activity monitors revealed that the animals’ sleep-like states remained highly fragmented long after the stimulant had left their biological systems. Sleep fragmentation involves frequent physical arousals that interrupt continuous rest. In human populations, this type of fragmented rest is linked to memory impairment, increased physical stress, and metabolic dysfunction.

While the findings demonstrate a link between methylphenidate withdrawal and altered rest patterns in an animal model, rats process medications differently than humans. The rats used in this study also did not have a neurological equivalent of ADHD. People taking the medication for a diagnosed condition might experience different physiological responses than a non-diseased animal subject.

The researchers measured sleep-like behavior using activity monitors that track physical movement rather than brain waves. True sleep architecture requires monitoring electrical activity in the brain to identify specific sleep stages. Relying on physical stillness provides a useful approximation for rest, but it does not capture the deeper neurological shifts associated with entering deep sleep.

Future research will need to explore exactly how early exposure to stimulants alters the brain’s long-term sleep and arousal circuitry. Previous rodent studies have suggested that withdrawing from stimulants can alter glucose metabolism in the hypothalamus, a brain region critical to regulating wakefulness. Researchers hope to determine if these prolonged sleep disturbances contribute to changes in cognitive function or reward processing later in life. Understanding these extended withdrawal effects could help doctors better manage the treatment plans of patients who eventually stop taking their medication.

The study, “Methylphenidate leads to disruptions in rest/wake patterns after discontinuation,” was authored by Carolyn Cueto, Magdalena R. Gonzales, Alexandra N. Tejada, Kimberly Guerrero Leon, Alexandra Mora, Andrew Cabrera, and Leslie R. Amodeo.

TITLE: Night owls may face a higher risk of acquired premature ejaculation

URL: https://www.psypost.org/night-owls-may-face-a-higher-risk-of-acquired-premature-ejaculation/

Men who naturally prefer staying up late might be more susceptible to developing premature ejaculation later in life, and they often experience more severe symptoms than early risers. A recent study found that this association is partly linked to lifestyle habits, highlighting how sleep preferences and daily behaviors influence sexual function. The research was published in The Journal of Sexual Medicine.

Premature ejaculation is one of the most common sexual health conditions affecting men worldwide. Doctors categorize it into two main subtypes based on when it begins. Lifelong premature ejaculation is present from a person’s first sexual encounters. The condition can also develop later in life after a period of normal sexual function, a state known as acquired premature ejaculation.

Men experiencing the acquired form often face a sudden onset of symptoms. The condition typically reduces the time to ejaculation to less than three minutes. This rapid shift causes considerable psychological distress and can rapidly impair a person’s overall quality of life.

Medical professionals have identified several risk factors for this acquired sexual dysfunction. Chronic pelvic pain, anxiety, and thyroid issues are all known to play a role. However, the exact biological and behavioral roots of the condition remain somewhat mysterious.

In clinical settings, doctors noticed a recurring pattern among patients dealing with acquired premature ejaculation. Many of these men seemed to favor late bedtimes and experienced erratic sleep schedules. They also struggled with emotional volatility and had a hard time maintaining healthy daily routines.

This observation led doctors to wonder if a person’s innate biological clock might influence their ejaculatory control. Chronotype refers to an individual’s natural internal circadian rhythm. This biological preference dictates an individual’s ideal times for sleeping and waking over a 24-hour cycle.

People are generally grouped into morning types, intermediate types, and evening types based on these natural rhythms. Those with an evening chronotype, colloquially called night owls, frequently experience poorer sleep quality. They are also more prone to anxiety and depressive symptoms, which are already known risk factors for sexual dysfunction.

Lead author Zhi Cao and a research team from the First Affiliated Hospital of Anhui Medical University and Peking University First Hospital in China designed an observational study to explore this potential connection. They wanted to see if an evening chronotype correlated with the presence and severity of acquired premature ejaculation.

The researchers also sought to understand if certain behavioral routines played a role in bridging this gap. Specifically, they looked at health promoting lifestyles, which encompass proactive habits like nutritious eating, regular physical exercise, and active stress management. Prior research has connected these positive habits to better erectile function and a lower risk of overall sexual dysfunction.

Because night owls often exhibit lower rates of physical exercise and more irregular sleep durations than morning types, the researchers formulated a testable hypothesis. They speculated that lifestyle habits might mediate the relationship between chronotype and ejaculatory control.

The study involved 1,011 adult men. This sample included 516 patients previously diagnosed with acquired premature ejaculation and 495 healthy control subjects. The control participants were matched to the patient group based on age, body mass index, and substance use history to ensure an even comparison.

Participants completed a series of paper questionnaires during visits to a medical clinic. These surveys evaluated their ejaculatory control, their baseline erectile function, and their natural position on the morning to evening chronotype spectrum. The surveys also assessed the men’s regular engagement in health promoting lifestyle habits.

Men in the diagnosed group filled out an additional survey to measure their illness perception. This concept refers to how threatening, persistent, and uncontrollable a patient believes their own medical condition to be. High illness perception means a patient feels deeply burdened or hopeless about their symptoms, while low illness perception suggests they view the condition as manageable.

The researchers found that men with acquired premature ejaculation scored globally lower on morningness and lifestyle habits than the healthy control subjects. Having an evening chronotype was statistically linked to the presence of the condition. Among the men dealing with the dysfunction, a stronger preference for staying up late correlated with worse ejaculatory control.

Circadian rhythm disruptions, which are common in night owls, might explain this link on a biological level. These internal cycles regulate numerous physiological processes, including the production of key neurotransmitters like serotonin and dopamine. Animal studies have shown that serotonin levels fluctuate in a circadian pattern, and central nervous system serotonin is closely linked to ejaculatory latency.

Disruptions in these monoamine systems could undermine the body’s ability to delay ejaculation. Statistical analyses in the current study revealed a secondary behavioral pathway at work. Daily habits partly explained the link between sleep preferences and sexual function in the patient group.

Individuals with an evening chronotype tended to engage in fewer health promoting behaviors. These diminished health habits in turn correlated with worse symptoms. The data indicated that lifestyle habits accounted for a substantial portion of the association between chronotype and symptom severity.

A patient’s individual perception of their condition altered these relationships. For men who felt a high degree of threat and lack of control regarding their sexual health, the positive association between being a morning person and having better lifestyle habits weakened. A similar attenuation appeared in the link between healthy habits and symptom severity.

When men feel overwhelmed by their condition, the potential benefits of regular exercise, nutrition, and stress management seem to diminish. High anxiety and constant symptom vigilance consume cognitive and emotional resources. This heavy psychological burden likely reduces the energy available to maintain healthy daily routines.

Because the study relied on taking a snapshot of data at a single point in time, the researchers cannot state that being a night owl directly causes acquired premature ejaculation. The relationships observed might operate in multiple directions. Repeated failures of ejaculatory control frequently trigger severe sexual performance anxiety.

This anxiety can activate the sympathetic nervous system, leading to difficulties initiating sleep. Progressive delays in bedtime could then reinforce an evening chronotype over time. Validating this cycle definitively requires observing patients over multiple years.

The participant pool was drawn from a single hospital in China, meaning the demographic sample was limited. Testing these variables across different cultural contexts and in broader community settings would help verify the patterns. The researchers also relied on self-reported questionnaires, which are vulnerable to recall bias and social desirability bias.

The researchers did not formally assess clinical anxiety or depressive symptoms beyond basic screening. Since these mental health factors heavily influence sleep, lifestyle, and sexual function, future studies will need to incorporate standardized psychological evaluations to get a more accurate picture of the dynamics at play.

Future research will need to track men over longer periods to see how sleep preferences and health routines evolve alongside sexual function. Clinical trials could eventually test whether targeted behaviors, like improving dietary habits or adjusting sleep schedules, actually improve ejaculatory control. In the meantime, medical professionals might benefit from asking patients about their sleep timing, daily lifestyle, and emotional reactions to their symptoms during routine consultations.

The study, “Chronotype is associated with acquired premature ejaculation: evidence from moderated mediation analysis,” was authored by Zhi Cao, Tianle Zhu, Yunlong Ge, Peng Yang, Yukuai Ma, Pan Gao, Hui Jiang, and Xiansheng Zhang.

A #SpaceMirror Will Test Turning Night Into Day. What To Know About the Controversial Project

by Jeffrey Kluger, Jul 14, 2026

Excerpt: "The company envisions multiple uses for sun-reflecting satellites: assisting search and rescue operations, allowing construction projects to operate around the clock, charging solar power stations, increasing crop yield. But critics cite all manner of risks. Human and animal #CircadianRhythms could be badly affected if the sun—or a simulacrum of it—never sets. The practice of changing the clocks by a mere hour twice a year is already known to mess with human sleep-wake cycles, after all. Plants could bloom when they shouldn’t and die before their time. Orbital mirrors flashing and winking back to Earth could distract airline pilots. Finally, #LightPollution is already interfering with astronomical observations—a problem made even worse by satellite constellations like #SpaceX’s 10,000-strong #Starlink fleet. #ReflectOrbital’s 50,000 birds would dwarf even that."

Big Picture Science for June 29, 2026: Skeptic Check: Blue Light Special

Many of us know the feeling: we intend to go to bed but pull out our phones for one last scroll. Setting them aside hours later, we’re wide awake, unable to fall asleep. For years, scientists have singled out blue light emitted from our devices as the key culprit behind our post-scrolling insomnia, but the scientific consensus is shifting. Although blue light signals to brains that its daytime, surprising new research suggests that our glowing screens may play a smaller role than previously thought.

We present the fascinating science around biological mechanisms of sleep and wakefulness, why circadian rhythms have more in common with your grandfather’s clock than you might think, and why scientists who question the role of blue light in causing nighttime restlessness, still don’t let our phones off the hook completely.

Guests:

#FCC Deciding Whether to Allow Startup to Launch Huge #MirrorSatellite to Blast Sunlight on Cities at Nighttime

"The implications for #wildlife, for all life, are enormous."

By Frank Landymore
Published Mar 10, 2026

Excerpt: "The idea is as far-fetched as it is controversial. But something like it has been attempted before. In 1993, the Russian satellite Znamya, or 'Banner,' deployed a 65-foot-wide sheet of mylar that reflected a beam of light twice as bright as the Moon, illuminating a roughly three mile wide circle onto the Earth below like an orbital spotlight. It didn’t prove to be practical, however, with ground observers noticing no more than a flash of light, and it was exorbitantly expensive to pull off.

"Even so, it has the potential to massively disrupt the environment and interfere with many human operations. And the far-reaching consequences of such a technology is exposing the limits of the FCC’s remit.

"Experts fear that light from space mirrors could disrupt circadian rhythms in nature, posing a problem for flora and fauna alike. Animals might breed at the wrong time, and hibernating insects and migrating birds could be confused, Martha Hotz Vitaterna, a research professor of neurobiology at Northwestern University, told the NYT. And plants could bloom when pollinators aren’t active.

" 'The implications for wildlife, for all life, are enormous,' added Vitaterna, who is co-director of the Center for Sleep and Circadian Biology."

Science has uncovered the role of light in mood changes and mental disorders https://www.psypost.org/science-has-uncovered-the-role-of-light-in-mood-changes-and-mental-disorders/?utm_source=dlvr.it&utm_medium=mastodon #MentalHealth #CircadianRhythms #MoodDisorders #LightTherapy #Depression

“Year-round Standard Time has the potential to promote healthier circadian rhythms on a population level.” #CircadianRhythms #DitchDST

Daylight Saving Time makes us set alarms an hour earlier than Standard Time. Permanent Standard Time aligns clocks to the sun, for naturally better sleep! #DitchDST #SleepHealth #CircadianRhythms

⏰🔄 The magic happens in the proteins!
We found that 10% of proteins and a whopping 66% of phosphorylated proteins in O. tauri follow daily rhythms. It's a microscopic dance in time with the light. #ProteinDance #CircadianRhythms 2/7
