Mounting scientific evidence reveals that the most accessible route to enhanced cognitive performance may be one already available to everyone: quality sleep. Leading neuroscientists demonstrate that sleep transcends simple energy restoration—it actively consolidates memories, eliminates metabolic brain waste, and strengthens neural pathways underlying problem-solving and creativity. This means improving sleep habits could boost academic performance and workplace productivity in ways that brief “brain training” applications cannot match, according to specialized neuroscience research interviews and comprehensive sleep studies.

A growing body of research suggests that the simplest route to sharper thinking and better learning may be the one most people already have access to: sleep. Neuroscientists say sleep does more than restore energy — it actively consolidates memories, clears metabolic waste from the brain and strengthens the neural pathways that underpin problem-solving and creativity. That means improving sleep habits could boost academic performance and work productivity in ways that short bursts of “brain training” apps cannot match (Tom’s Guide interview with a neuroscientist).

James B. Maas, the pioneering psychologist who popularized the concept of the “power nap,” passed away on June 23, 2025, at the age of 86. Revered for transforming tiredness into a subject of national fascination and workplace reform, Professor Maas’s work left an indelible mark on how sleep is valued—especially the brief midday nap that claims to refresh both body and mind. Following his passing, the global scientific community continues to expand on his foundational insights, revealing the intricacies of why short naps offer unique cognitive benefits and the right way to integrate them into modern lives, including those of Thais grappling with work-life pressures and sleep deficits.

A major new study tracking 20,000 adults has sparked fresh debate over bedtime habits, revealing that going to bed earlier may have profound health benefits. The findings, highlighted in a recent report drawing international attention, suggest that shifting to an earlier sleep routine is associated with improved mood, better physical wellbeing, and a lower risk of chronic illness. This expansive research is sending ripples through Thailand’s health community, where late-night working and screen-time culture are on the rise.

A groundbreaking research initiative at Penn State University is poised to unlock new secrets about nightmares and their intricate relationships with anxiety-related mental health disorders—a move that could ultimately shape how conditions like PTSD are predicted, prevented, and managed worldwide, including in Thailand.

Nightmares, those unsettling nocturnal experiences, are a nearly universal phenomenon among humans and many animals. Yet, the question of why dreams—especially bad ones—occur and what purpose they serve has eluded scientists for centuries. Now, thanks to a three-year, US$1.2 million grant from the W.M. Keck Foundation, an interdisciplinary neuroscience team is taking aim at this enduring mystery. According to principal investigators at Penn State, the study aims to illuminate how nightmares emerge and whether they are a symptom, a cause, or even a warning sign for serious mental health conditions such as post-traumatic stress disorder (PTSD) and anxiety disorders (psu.edu).

A short daytime nap, especially one that allows a person to reach a deeper stage of sleep known as N2, may considerably boost the likelihood of experiencing creative breakthroughs and “aha” moments, according to a groundbreaking new study published in PLOS Biology. The research offers the first neural clues suggesting why even brief sleep might help the brain connect dots that were previously hidden, with potential implications for Thai students, professionals, and anyone seeking to enhance their problem-solving abilities.

A major new study from Harvard Medical School and Massachusetts General Hospital warns that certain common patterns of daytime napping—especially long, irregular, or midday-heavy naps—may signal a higher risk of premature death. This research, considered among the most robust to date on napping and mortality, has sparked fresh debate on whether taking a nap is always the healthy break many believe it to be, raising important questions for millions in Thailand and around the world who routinely indulge in afternoon siestas.

A growing body of research is lending scientific weight to a tradition long observed by artists, inventors, and thinkers worldwide: the creative spark ignited by a nap. Recent studies and expert commentary, as highlighted in reputable outlets such as Psychology Today and ScienceAlert, suggest that even short episodes of daytime sleep can enhance creative thinking and problem-solving abilities in ways both measurable and meaningful for people of all ages.

The significance of this news resonates strongly for Thai readers, reflecting longstanding local practices of midday rest and challenging contemporary perceptions that equate constant alertness with productivity. As Thailand’s economy and education system increasingly prioritise innovation and digital skills, understanding the cognitive benefits of napping could shift attitudes among educators, employers, and families alike.

Scientific curiosity about dreams has captured the human imagination for centuries, yet neuroscientists have only recently started to unravel why some people vividly recall their dreams while others wake up with no memory at all. As reported in May 2025 in a new study published in Communications Psychology, researchers have identified multiple factors—ranging from sleep patterns to personality traits—that influence an individual’s ability to remember dreams, offering fresh insights with both global and Thai relevance (Medscape).

A new review has shed light on why people living with obsessive-compulsive spectrum disorders (OCSDs), chronic tic disorders (CTDs), and attention-deficit/hyperactivity disorder (ADHD) often experience pronounced sleep disturbances—as well as how these intertwined problems could one day be better managed. The research, recently published in the Harvard Review of Psychiatry and summarised by several neuroscience outlets, finds that disruptions in a crucial brain circuit, the cortico-striatal-thalamo-cortical (CSTC) pathway, underpin both the psychiatric symptoms and the insomnia, delayed sleep onset, and other sleep issues reported in these populationsNeuroscience News.

A new study has revealed that lucid dreaming is not simply a vivid form of REM sleep, but constitutes an entirely unique state of consciousness—one with neurological hallmarks that set it apart from both waking and ordinary dreaming. This major breakthrough in sleep science, published in The Journal of Neuroscience, offers tantalising implications for understanding the human mind and may one day help people harness more of their cognitive potential—even outside of sleep.

A new wave of parenting discussion has swept through Thailand, mirroring a global debate on the benefits and challenges of co-sleeping with children beyond infancy. Prompted by recent commentary such as “I still co-sleep with my seven-year-old daughter” from The Times, Thai parents and experts are reflecting on both cultural traditions and modern research to navigate what is best for their families.

For generations, co-sleeping—where parents and children share the same bed or bedroom—has been deeply rooted in Thai culture as a way to foster closeness, emotional security, and familial bonds. Many Thai families consider it a practical solution, especially in multi-generational households with limited space, and a way to ensure a child’s safety and comfort during the night. However, as Western parenting philosophies gain influence and research on child development evolves, more Thai parents are questioning when—and if—children should transition to sleeping alone.

In a groundbreaking study, researchers have unveiled that letting our minds wander during simple tasks can enhance learning, challenging the long-held belief that focused attention is always necessary for effective learning. Conducted by Péter Simor and colleagues at Eötvös Loránd University, the research, published in JNeurosci, examined the impact of spontaneous mind wandering on low-effort learning tasks. It revealed that participants who allowed their minds to drift performed just as well, if not better, than when they were fully focused, highlighting the cognitive benefits of states akin to daydreaming.
