An evidence-first journal of sleep science. No supplements to sell. No mattresses to push. Just careful reading of the literature, in plain English.
Six years after the finale of the American television show The Biggest Loser, a group of former contestants had a problem their scales could not explain.
Actigraphy (wearable sleep tracking) detects rest-wake patterns via motion sensors, offering an accessible alternative to polysomnography for monitoring insomnia, shift work, and circadian disorders with research evidence on accuracy and clinical utility.
Sleep treatment adherence determines whether insomnia therapies, CPAP machines, and sleep protocols actually work in real life, covered through compliance research.
Sleep algorithms predict wake timing and sleep stages using movement data, heart rate patterns, and machine learning models to improve sleep tracking accuracy.
Allergies disrupt sleep quality through nasal congestion, itching, and nighttime symptoms. Research on allergen management, antihistamines, and sleep environment optimization.
AMP-activated protein kinase regulates cellular energy and metabolism during sleep, affecting circadian rhythm timing, sleep quality, and metabolic health outcomes.
Antioxidants reduce oxidative stress linked to poor sleep quality, aging, and disease—here's what the research shows about their actual effects.
Appetite regulation during sleep explores hunger hormones, late-night eating, and how sleep deprivation affects food cravings and weight gain.
Aspartame is an artificial sweetener linked to sleep, metabolism, and circadian rhythm disruption. Research summaries and evidence reviews on dosage effects.
