Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

REM Sleep Reactivation Locks Memories in Place

Rare adult-born neurons in the hippocampus are reactivated during REM sleep, locking waking experiences into long-term memory. Using genetically modified mice, they found that these neurons fire in the same patterns during sleep as they did during learning.

Cannabis Linked to Reduced Insomnia and Anxiety

A new study suggests cannabis-based medical products may help people with insomnia sleep better over the long term. Across 124 patients followed for up to 18 months, participants consistently reported improved sleep quality, less anxiety and depression, and a better overall quality of life.

Omega-3s May Protect Against Daytime Sleepiness

A new study has identified seven blood metabolites linked to excessive daytime sleepiness (EDS), a condition affecting one in three Americans. The findings show that both diet and hormones play a role, with omega-3 and omega-6 fatty acids associated with lower risk, and compounds like tyramine linked to higher risk.

Nighttime Brain Activity Keeps Glucose Levels in Check

A new study reveals that the brain actively maintains blood sugar stability during everyday life, not just during crises. Researchers identified VMHCckbr neurons in the hypothalamus that regulate glucose by promoting fat breakdown, especially during the early hours of sleep.

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.
