Researchers have uncovered a strikingly consistent pattern in how brain activity unfolds during the transition from sleep to wakefulness: the brain doesn’t wake up all at once, it orchestrates a precise sequence of activation 🧠💤➡️🌅

Why we need sleep may lie in mitochondria 💤🔋. When mitochondria of certain sleep-regulating brain cells (studied in fruit flies 🐞) become overcharged, they leak electrons ⚡, producing potentially damaging reactive oxygen species ☣️. This mitochondrial electron leak triggers sleep when a threshold is crossed.

**New study found considerable variation between people in how strongly sleep attenuates sounds 🔊💤, which may explain why people differ in their sensitivity to nighttime noises 🌙. Because sound continues to be processed to some level during sleep, maintaining a quiet sleeping environment is a good idea.**

Dopamine neurons—the cells that drive reward & motivation while we’re awake—become surprisingly active during nonrapid eye movement sleep 💤 right after we learn something new. This night surge 🌙 that helps strengthen motor memories 🏃‍♂️ and improves motor skills, according to a new U-Michigan study.

🧠💤⚡ Sleep loss damages the brain’s wiring insulation, called myelin, leading to conduction delays and disrupted interhemispheric synchronization. Cognitive and motor performance are affected, and the deficits persist beyond recovery sleep. Restoring cholesterol delivery to myelin prevents them.

* 😴 New research from March 23, 2026, suggests that anticipating stressful events can lead to more negative dreams and disrupted sleep, especially in the early morning hours.

* 🧠 Investigators Sandrine Baselgia and Björn Rasch explored whether stressful dream content explains why sleep deteriorates when anticipating a difficult task.

* 💡 Reducing anticipated stress can improve both dreams and sleep quality, with techniques like CBT-I, good sleep hygiene, and stress-reduction methods recommended.

🚀 SLEEP Advances: 2025 Review & 2026 Outlook
In 2025, SLEEP Advances accepted 11 Protocol Papers and launched 4 Special Collections, with plans to promote Protocol Papers from 2025 in a new "Advances in Sleep and Circadian Protocols 2025" collection. The journal also introduced its first "Reviewers of the Year" awards, recognizing Chin Moi Chow, Greg Elder, Erin Hanlon, Anthony Reffi, Jennifer Tudor, and Emerson Wickwire.

📝 Editorial Team & New Initiatives
Eight new Associate Editors are joining in 2026, selected for their expertise and geographic representation. Dr. Rebecca Robbins will lead the Social Media efforts. The journal also thanks outgoing Associate Editors and Editorial Advisory Board members for their contributions.

📅 2026 Special Collections & Focus Areas
Three Special Collections are planned for 2026: "Sleep and Circadian Mechanisms in Mental Health" (launching soon with a late June submission deadline), "AI, Machine Learning, and Data Science in Sleep and Circadian Rhythms," and "Lived Experience and Codesign in Sleep and Circadian Science" (both with Q3/Q4 submission deadlines). A Supplement Issue on sodium oxybate therapy is also scheduled.

Women rate their sleep quality lower than men, despite sleeping better. This is because they estimate their night-time awakenings more accurately than men, who tend to underestimate their frequency of wakefulness

🧠 New study in Alzheimer's & Dementia suggests brain immune cells (microglia) may be responsible for sleep loss in Alzheimer's, not just amyloid-beta plaques.

💤 Researchers found that disabling microglia in mice with Alzheimer's restored 2 hours of sleep per night, highlighting the importance of this restorative sleep for brain health.

🔬 The study also identified early brain changes at six months in mice that could potentially flag Alzheimer's progression in the future, possibly through portable EEG monitoring.

🧠 New UC Berkeley research published Sept. 11, 2026, links the buildup of tau protein, a marker for Alzheimer's disease, to disruptions in deep non-REM sleep.

💤 These disruptions affect slow brain waves crucial for forming episodic memories, leading to poorer memory recall, even before Alzheimer's symptoms are apparent.

🔬 The study used EEGs and PET scans, showing that older adults with more tau in their frontal cortex had less synchronized brain waves during deep sleep and weaker memory consolidation.

🧠 Brains stay alert to noise during sleep, especially sounds that could signal danger.

☁️ The study found sleep environment disruptions didn't impact sleep duration in young adults, possibly due to their ability to sleep in later.

👂 Researchers focused on personal perception of sleep disruptors, not just objective measures like noise levels, as experiences are individual.

🌱 Developing good sleep habits in young adulthood is crucial for long-term health, similar to childhood habits.

Cannabis may not actually help you sleep better: a 35-year study of 1,266 U.S. adults found long-term and recent users slept worse when tracked by wrist monitors (more waking up, more broken sleep), yet they didn't notice it themselves and rated their sleep just as good as nonusers did.
