Irregular Sleep Linked to 172 Diseases

In the largest study of its kind, researchers linked irregular sleep patterns to elevated risk for 172 diseases. Using objective sleep data from actigraphy devices worn by over 88,000 people for nearly seven years, the study found that erratic bedtimes and poor circadian stability were among the most damaging traits.

Inflammation Influences Cannabis’s Effects on Anxiety and Sleep

A new study shows that inflammation levels influence how cannabis affects anxiety and sleep quality. Researchers found no overall change in inflammatory markers after 4 weeks of cannabis use, but baseline inflammation moderated outcomes.

Math Reveals Why Sleep Patterns Shift With Age, Light, and Routine

A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier. Researchers expanded the classic two-process sleep model by adding the effects of light exposure, uncovering how internal and external factors interact to regulate sleep.

Hunger Sharpens Sleep Rhythms That Solidify Memories

New research shows that the brain’s slow oscillations and sleep spindles — key rhythms that consolidate memories during sleep — can be shaped by more than just age. While these rhythms have long been thought of as stable traits, studies reveal that metabolic state, like fasting before sleep, can enhance their timing and co-occurrence.

Sleeping Brain Reveals Clues to Hidden Disorders

The brain remains highly active during sleep, and mapping this activity can reveal early signs of neurological and sleep disorders. Using rare intracranial EEG data, researchers refined methods to distinguish functional areas of the cerebral cortex based on their unique electrical activity, even at rest.

Sleep to Consciousness: How the Brain Transitions from Dreams to Reality

Each morning, your brain undergoes a precise sequence to shift from sleep to wakefulness, reorienting you to the world. A study using high-density EEG recordings found that awakening begins in frontal regions and spreads backward, with distinct patterns depending on whether you wake from REM or non-REM sleep.

Oxytocin Protects Mood During Sleep Loss

New research suggests oxytocin, the so-called “love hormone,” may help protect women from mood disturbances caused by sleep disruption and hormonal changes during postpartum and menopause. In a controlled study, women with higher oxytocin levels before sleep fragmentation reported fewer mood symptoms the following day.

Eating Dairy May Trigger Nightmares

A new study links lactose intolerance and food sensitivities to disrupted sleep and frequent nightmares. Researchers surveyed over 1,000 students and found that those with dairy intolerance reported more vivid and disturbing dreams, likely due to nighttime gastrointestinal discomfort.

Sleep Learning: How Synapses Strengthen While We Rest

New research reveals how synaptic connections in the cerebral cortex can strengthen during sleep, offering insight into how the brain continues learning even while we rest. Using computer simulations, researchers demonstrated that synaptic activity during sleep follows known "synaptic learning rules" when neural activity reaches specific thresholds.

Short Naps Linked to “Aha” Moments and Creative Insight

A new study suggests that a short nap, especially one reaching deeper N2 sleep, can significantly boost problem-solving insight. Participants who achieved N2 sleep were far more likely to discover a hidden shortcut in a task after napping.

Sleep’s Secret Sequence May Sculpt Our Memories Like a Garden

A new theory suggests that the order of sleep phases—non-REM followed by REM—is essential for strengthening and organizing memories. In mice studies and computational models, researchers found that non-REM sleep reinforces new memories, while REM sleep prunes overlapping or irrelevant ones, keeping them distinct.

How Sleep Deprivation Amplifies Pain in Migraine

New research reveals that sleep deprivation alters how the brain processes pain in people with migraines. Using EEG and pain stimulation, scientists found that migraine sufferers’ brains respond differently after poor sleep, showing reduced ability to suppress pain signals.
