Hitting Snooze Disrupts REM Sleep

Despite expert warnings, hitting the snooze button is a common part of many people’s morning routines. A large global study analyzing data from over 21,000 individuals found that snoozing occurred in 56% of sleep sessions, with heavy users snoozing for up to 20 minutes each morning.

Insomnia Isn’t Just About Sleep, Your Personality Plays a Role

Certain personality traits significantly influence the risk of developing insomnia. People with high levels of neuroticism—a trait linked to emotional instability—were much more likely to experience sleep disturbances.

This shows a brain and a person sleeping.

Excessive Sleep May Hurt Cognitive Function

Sleeping more than nine hours a night may be detrimental to brain health, particularly for individuals experiencing symptoms of depression, according to a new study. Researchers analyzed data from nearly 2,000 dementia-free adults and found that long sleep duration was associated with worse performance in memory, visuospatial ability, and executive function.

Sleep Apnea Erodes Memory Over Time

Obstructive sleep apnea (OSA) contributes to significant memory decline, especially in visual and verbal working memory, according to a new review of human and animal studies. Key features of OSA, intermittent hypoxia and sleep fragmentation, drive brain inflammation, oxidative stress, and neuronal injury, impairing memory and cognition.

Why OCD, Tics, and ADHD Keep You Up at Night

People with obsessive-compulsive spectrum disorders (OCSDs), chronic tic disorders (CTDs), and ADHD often suffer from significant sleep disturbances, and a new review suggests that disruptions in the cortico-striatal-thalamo-cortical (CSTC) pathway may be the reason why. The review highlights how dopamine and GABA dysregulation in CSTC circuitry contributes to both poor sleep and the disorders themselves, suggesting a bidirectional and additive relationship.

Does the TikTok Grounding Trend Really Improve Sleep?

Grounding, or physically connecting the body to the Earth, has gained traction as a wellness trend—now even through high-tech mats and sheets designed to replicate direct Earth contact. Advocates claim benefits for sleep, mood, and recovery, but scientific evidence remains limited.

Shared Brain Circuit Links Insomnia, Anxiety, and Depression

A large brain imaging study suggests that insomnia, depression, and anxiety—often co-occurring—share overlapping brain abnormalities. Researchers found reduced cortical surface area, smaller thalamic volume, and weaker brain connectivity across all three disorders, while each also displayed unique neural patterns.

What Poor Sleep Really Does to Your Brain

Chronic sleep disorders and short-term sleep deprivation affect different regions of the brain, highlighting distinct neural impacts. A meta-analysis of 231 brain studies showed that chronic sleep disorders alter regions involved in emotions and memory, while short-term deprivation primarily affects attention and movement regulation.

Sleep Prepares the Brain for Both Past Memories and Future Learning

A new study reveals that sleep not only consolidates existing memories but also primes the brain for future learning. Researchers tracked neuronal activity in mice and discovered 'engram-to-be cells' that synchronize during sleep, preparing to encode new experiences.

What Makes Dreams Memorable? Study Reveals Three Key Predictors

Not everyone remembers their dreams, and a new study reveals why. Researchers found that dream recall is most strongly influenced by a person’s attitude toward dreams, their tendency to mind-wander, and specific sleep characteristics.

Earlier Bedtimes Linked to Better Brain Function in Adolescents

A large-scale study has found that adolescents who go to bed earlier and get slightly more sleep show better brain function and higher cognitive test performance than their peers. Using wearable devices and brain imaging from over 4,000 participants, researchers discovered that even small differences in sleep duration and timing impacted brain volume and task performance.

Lucid Dreaming Reveals a New Layer of Conscious Brain Activity

Lucid dreaming, where people become aware they are dreaming, has long fascinated both scientists and dreamers. A new study with the largest dataset of its kind has identified distinct brain activity patterns that separate lucid dreaming from both REM sleep and wakefulness.
